Subject: [PATCH 2/7] Fix pico-ice board configuration

- Fix SPI pin definitions to match actual pico-ice pinout (GPIO 8,11,10,9,14)
- Change LED from GPIO15 (blue, WS2812) to GPIO12 (green, GPIO) to avoid capture conflicts
- Set INPUT_PIN_BASE to 0 to match GPIO0-7 capture range
- Add PIN_MAP definition for GPIO0-7, GPIO12-27 capture channels
- Build now succeeds without errors

+# Goal 1
+Our goal is to make this logic analyzer work with the pico-ice.  The pico-ice is an FPGA developer board for the ICE40UP5K that uses the RP2040 to provide an easy way to program the FPGA.  It also provide a clock and can provide some I/O for the FPGA depending on the designer's wishes.  The RP2040 and FPGA share a number of pins which will make this handy for debugging FPGA projects.  This is the first step to a larger project that will work with other similar development boards like the pico2-ice.  
+
+## How we will proceed
+I will have the pico-ice flash already programmed, so all that is required is to pull the \ICE_RESET high which will initiate the process of loading the CRAM in the FPGA from flash.  When it is finished a signal CDONE will be asserted.  When CDONE is asserted I would like to use the PIO to generate the FPGA clock (PIN_CLOCK).  It will be at 10 MHz, but it would be nice to make it obvious how to change the frequency for users.  After that I would like the logic analyzer code in this repository to take over so I can use it to monitor the device.  We need to very carefully make sure that the logic analyzer code does not mess up what we are doing with the FPGA clock it its initialization.  I want to follow the way this has been done in the past, where #defines are made for the PICO and the PICO_2, etc., but use the PICO_ICE, so the code can still be built for the pico, etc.  Please comment things carefully so it is obvious what we are doing.  The logic analyzer connects via USB CDC using escaped binary.  I would like this new firmware to identify that it is running on a pico-ice.
+I do not want to use TURBO_MODE for development at all.  It has caused strange things to speed up the RP2350 or RP2040, so let's set that to zero.  I want the software to match what is already there in style.
+
+## Notes for the pico-ice
+The pico-ice documentation is at: https://pico-ice.tinyvision.ai/md_getting__started.html   The pico-ice uses the RP2040 to transfer data to and from the FPGA CRAM.  I am including the ICE40UP5K FPGA datasheet converted from pdf to text (Firmware/FPGA-dS.txt) for you to refer to.
+
+### Pinout for the pico-ice
+#### For pico-ice (using the RP2040):
+GPIO8 = PIN_ICE_SI (ICE_SI, RP2040 ➜ FPGA)
+GPIO11 = PIN_ICE_SO (ICE_SO, FPGA ➜ RP2040)
+GPIO10 = PIN_ICE_SCK (ICE_SCK)
+GPIO9 = PIN_ICE_SSN (sysCONFIG SS, active-low)
+GPIO14 = PIN_RAM_SS (External PSRAM SS)
+GPIO27 = PIN_FPGA_CRESETN (CRESET_B, active-low)
+GPIO26 = PIN_FPGA_CDONE (CDONE)
+GPIO24 = PIN_CLOCK (clock to FPGA)
+GPIO13/12/15 = LED_R/G/B (active-low)
+
+#### pico-ice pins to capture logic analyzer data from:
+GPIO0-GPIO7
+GPIO12-GPIO27  Note: GPIO24 and GPIO27 are also outputs, but I wish to be able to monitor them with the logic analyzer.
+
+# Goal 2
+We want to do the same thing we already accomplished in Goal 1, but for the pico2-ice.  So we will add the board build for the pico2-ice.  The big differences between the pico-ice and the pico2-ice are processor in the pico2-ice is the RP2350B instead of the RP2040, and the pinout (see below) is a bit different for the pico2-ice.  
+
+## Notes for the pico2-ice
+The pico2-ice documentation is at: https://pico2-ice.tinyvision.ai/md_getting__started.html   The pico2-ice uses the RP2040 to transfer data to and from the FPGA CRAM.  I am including the ICE40UP5K FPGA datasheet converted from pdf to text (Firmware/FPGA-dS.txt) for you to refer to.
+
+### Pinout for pico2-ice
+#### For pico2-ice (RP2350):
+
+GPIO4 = PIN_ICE_SI (ICE_SI, RP2350 ➜ FPGA)
+GPIO7 = PIN_ICE_SO (ICE_SO, FPGA ➜ RP2350)
+GPIO6 = PIN_ICE_SCK (ICE_SCK)
+GPIO5 = PIN_ICE_SSN (sysCONFIG SS, active-low)
+GPIO31 = PIN_FPGA_CRESETN (CRESET_B, active-low) - Correct per pico-ice-sdk
+GPIO40 = PIN_FPGA_CDONE (CDONE) - Correct per pico-ice-sdk
+GPIO21 = PIN_CLOCK (clock to FPGA)
+GPIO1/0/9 = LED_R/G/B (active-low)
+No external PSRAM (PIN_RAM_SS = -1)
+
+pico2-ice pins to capture data from:
+GPIO20-GPIO43
+
+We want to output the FPGA clock and the CRESETN the same way we did for the pico-ice so we can have them going all the time, but also monitor them.

+# Fixing Our Mess 4:30 a.m. of 9/25/2025
+Okay, we are changing goals, because we are just fighting bugs we have created in this project, by letting the AI have way too much freedom.  We have strayed too far from the original code to get a pull request accepted, and introduced new bugs in the process.  We have code that works for the BOARD_PICO_2 which is a very close relative of the BOARD_PICO_2_ICE.  Likewise we have code for the BOARD_PICO which is very similar to the BOARD_PICO_ICE.  This code is at git commit 3fa3703c80d8499cbfeec0e33c5837cf09a08587 which is ahead of our work.  We just need to git diff between the Firmware/LogicAnalyzer_V2/ at 3fa3703c80d8499cbfeec0e33c5837cf09a08587 for the PICO_2, and what we have here to figure out the communication bugs.  We need to closely examine these diffs to determine what is going wrong with the communication between the GUI and the firmware. 
+
+# PRIME DIRECTIVE
+ I WANT MINIMAL CHANGES TO 3fa3703c80d8499cbfeec0e33c5837cf09a08587 TO ACHIEVE MY GOALS! This is imperitive to get my pull request accepted, and will introduce minimal bugs, so follow this as the prime directive!
+
+### Branches I Need
+You will need to create these branches.  Each branch is for a pull request to the original Dr Gusman repository.  The changes on 1 will only be needed if it does not already build on Linux.  Numbers 2 and 3 are each for a seperate board we wish to add to Dr. Gusman's LogicAnalyzer project.
+
+1. build_for_linux  This branch is to be like 3fa3703c80d8499cbfeec0e33c5837cf09a08587, with the only difference that it will build 3fa3703c80d8499cbfeec0e33c5837cf09a08587 for the BOARD_PICO and BOARD_PICO_2 here on Linux, which may not work now.  The only changes that should be made are in the cmake files for this branch and it is possible it builds for Linux already.  If it builds already, we do not need this branch. 
+2. new_pico_ice  This branch will add the pico-ice board to the firmware. We have working pico-ice firmware at 89fd601647d5f81dbd77dcb84df9eda8edc04c79.  The goal here is to make the changes minimal from 3fa3703c80d8499cbfeec0e33c5837cf09a08587, while still having it work for the BOARD_PICO_ICE.
+3. new-pico2-ice  This branch is to be like 3fa3703c80d8499cbfeec0e33c5837cf09a08587, with only minimal changes.  We have working FPGA clock and CRESETN firmware in the pico-ice-wip branch that has issues with the commmunication with the GUI, but the code in 3fa3703c80d8499cbfeec0e33c5837cf09a08587 built for the BOARD_PICO_2 has working communication code.
+
+## Other Notes
+
+The changes for the pico-ice and pico2-ice are described in the other prompt (firmwareonly_prommpt.md) and you are familiar with them as you have this pico2-ice-wip and for the pico-ice, this 89fd601647d5f81dbd77dcb84df9eda8edc04c79.  I wish to tackle these three repositories in the order they are listed, because I found the pico-ice easier to make work than the pico2-ice.  I really need the pico2-ice for my class, but doing it in small steps is the only way I can see this working.

Subject: [PATCH 3/7] Complete FPGA pin protection for pico-ice

- Add protection for GPIO24 (FPGA clock) and GPIO27 (CRESETN) pins in all capture functions
- Prevents PIO from taking ownership of critical FPGA output pins during captures
- Allows monitoring these pins without interfering with FPGA operation
- Maintains minimal changes approach - only protects the two critical output pins

Subject: [PATCH 5/7] Implement universal output protection for all capture
 functions

- Replace all pico-ice specific PIN_FPGA_CRESETN/PIN_CLOCK checks with gpio_is_dir_out()
- Apply universal protection to all capture modes: Simple, Fast, Complex, Blast
- Protect both pio_gpio_init() and pio_sm_set_consecutive_pindirs() calls
- Preserve output pins (FPGA clocks, LEDs, etc.) while allowing monitoring
- Add clear comments explaining how to revert if needed
- Remove all BUILD_PICO_ICE conditional compilation from capture logic
- Solution works for any board with output pins, not just pico-ice

-# Goal 1
-Our goal is to make this logic analyzer work with the pico-ice.  The pico-ice is an FPGA developer board for the ICE40UP5K that uses the RP2040 to provide an easy way to program the FPGA.  It also provide a clock and can provide some I/O for the FPGA depending on the designer's wishes.  The RP2040 and FPGA share a number of pins which will make this handy for debugging FPGA projects.  This is the first step to a larger project that will work with other similar development boards like the pico2-ice.  
-
-## How we will proceed
-I will have the pico-ice flash already programmed, so all that is required is to pull the \ICE_RESET high which will initiate the process of loading the CRAM in the FPGA from flash.  When it is finished a signal CDONE will be asserted.  When CDONE is asserted I would like to use the PIO to generate the FPGA clock (PIN_CLOCK).  It will be at 10 MHz, but it would be nice to make it obvious how to change the frequency for users.  After that I would like the logic analyzer code in this repository to take over so I can use it to monitor the device.  We need to very carefully make sure that the logic analyzer code does not mess up what we are doing with the FPGA clock it its initialization.  I want to follow the way this has been done in the past, where #defines are made for the PICO and the PICO_2, etc., but use the PICO_ICE, so the code can still be built for the pico, etc.  Please comment things carefully so it is obvious what we are doing.  The logic analyzer connects via USB CDC using escaped binary.  I would like this new firmware to identify that it is running on a pico-ice.
-I do not want to use TURBO_MODE for development at all.  It has caused strange things to speed up the RP2350 or RP2040, so let's set that to zero.  I want the software to match what is already there in style.
-
-## Notes for the pico-ice
-The pico-ice documentation is at: https://pico-ice.tinyvision.ai/md_getting__started.html   The pico-ice uses the RP2040 to transfer data to and from the FPGA CRAM.  I am including the ICE40UP5K FPGA datasheet converted from pdf to text (Firmware/FPGA-dS.txt) for you to refer to.

-### Pinout for the pico-ice
-#### For pico-ice (using the RP2040):
-GPIO8 = PIN_ICE_SI (ICE_SI, RP2040 ➜ FPGA)
-GPIO11 = PIN_ICE_SO (ICE_SO, FPGA ➜ RP2040)

-GPIO26 = PIN_FPGA_CDONE (CDONE)
-GPIO24 = PIN_CLOCK (clock to FPGA)
-GPIO13/12/15 = LED_R/G/B (active-low)
-
-#### pico-ice pins to capture logic analyzer data from:
-GPIO0-GPIO7
-GPIO12-GPIO27  Note: GPIO24 and GPIO27 are also outputs, but I wish to be able to monitor them with the logic analyzer.
-
-# Goal 2
-We want to do the same thing we already accomplished in Goal 1, but for the pico2-ice.  So we will add the board build for the pico2-ice.  The big differences between the pico-ice and the pico2-ice are processor in the pico2-ice is the RP2350B instead of the RP2040, and the pinout (see below) is a bit different for the pico2-ice.

+# Using the Logic Analyzer with pico-ice
+
+The **pico-ice** is an FPGA development board featuring the **ICE40UP5K FPGA** paired with the **RP2040** microcontroller. This guide explains how to use Dr. Gusman's Logic Analyzer firmware with the pico-ice board for debugging FPGA projects.
+
+## Overview
+
+The pico-ice Logic Analyzer firmware provides a seamless integration between FPGA development and logic analysis. The RP2040 handles both FPGA configuration management and high-speed logic capture, making it an ideal tool for FPGA debugging and verification.
+
+## Prerequisites
+
+### 1. FPGA Flash Programming Required
+
+**⚠️ IMPORTANT: You must program the FPGA flash memory before using the Logic Analyzer.**
+
+The pico-ice Logic Analyzer firmware does **NOT** program the FPGA flash. You need to:
+
+1. Program your FPGA bitstream to the onboard flash memory using standard pico-ice tools
+2. Ensure your FPGA design is stored in flash and ready for configuration
+3. Only then use the Logic Analyzer firmware
+
+**Programming Tools:**
+- Use the official pico-ice SDK and tools for flash programming
+- Refer to the [pico-ice documentation](https://pico-ice.tinyvision.ai/md_getting__started.html) for detailed programming instructions
+- Popular tools include `iceprog`, `openFPGALoader`, or the pico-ice MicroPython utilities
+
+### 2. Hardware Requirements
+
+- pico-ice development board
+- USB cable for connection to host computer
+- paper clip to put the pico-ice in bootsel mode
+- FPGA bitstream programmed in flash memory
+
+## How It Works
+
+### FPGA Initialization Sequence
+
+When the Logic Analyzer firmware starts:
+
+1. **Reset Release**: The RP2040 pulls `CRESETN` (GPIO27) high, releasing the FPGA from reset
+2. **Configuration Loading**: The ICE40UP5K automatically loads its configuration from onboard flash memory
+3. **Configuration Complete**: The FPGA asserts `CDONE` (GPIO26) when configuration is successful
+4. **Clock Generation**: Once `CDONE` is high, the RP2040 generates a **10MHz clock** on `PIN_CLOCK` (GPIO24) using PIO
+5. **Logic Analysis Ready**: The Logic Analyzer is now ready to capture signals while maintaining FPGA operation
+
+### Dual Functionality
+
+The firmware provides **dual functionality**:
+- **FPGA Support**: Manages FPGA configuration, reset control, and clock generation
+- **Logic Analysis**: Captures high-speed digital signals from GPIO pins for analysis
+
+## Pin Configuration
+
+### FPGA Control Pins
+- **GPIO27** (`CRESETN`) - FPGA reset control (active-low) - **OUTPUT**
+- **GPIO26** (`CDONE`) - FPGA configuration done status - **INPUT**
+- **GPIO24** (`PIN_CLOCK`) - FPGA clock output (10MHz) - **OUTPUT**
+
+### SPI Flash Programming Pins
+- **GPIO8** (`ICE_SI`) - SPI MOSI to FPGA
+- **GPIO11** (`ICE_SO`) - SPI MISO from FPGA  
+- **GPIO10** (`ICE_SCK`) - SPI clock
+- **GPIO9** (`ICE_SSN`) - SPI chip select (active-low)
+- **GPIO14** (`RAM_SS`) - External PSRAM chip select
+
+### Logic Analyzer Capture Pins and Channel Mapping
+
+The Logic Analyzer can monitor these GPIO pins:
+- **GPIO0-GPIO7** - General purpose I/O
+- **GPIO12-GPIO27** - Extended I/O range
+
+**Channel to GPIO Pin Mapping:**
+```
+Logic Analyzer Channel → GPIO Pin
+Channel 0  → GPIO0    Channel 12 → GPIO20
+Channel 1  → GPIO1    Channel 13 → GPIO21  
+Channel 2  → GPIO2    Channel 14 → GPIO22
+Channel 3  → GPIO3    Channel 15 → GPIO23
+Channel 4  → GPIO4    Channel 16 → GPIO24 (FPGA Clock) 🕐
+Channel 5  → GPIO5    Channel 17 → GPIO25
+Channel 6  → GPIO6    Channel 18 → GPIO26 (CDONE) 📡
+Channel 7  → GPIO7    Channel 19 → GPIO27 (CRESETN) 🔄
+Channel 8  → GPIO12   
+Channel 9  → GPIO13   Note: 🕐 = 10MHz FPGA clock output
+Channel 10 → GPIO14   📡 = FPGA configuration done status  
+Channel 11 → GPIO15   🔄 = FPGA reset control (active-low)
+```
+
+**Important Notes:**
+- **Channels 16, 18, 19** (GPIO24, 26, 27) have special FPGA functions but can still be monitored
+- **GPIO24** shows the 10MHz FPGA clock - useful for timing reference
+- **GPIO26** shows FPGA configuration status (high when FPGA is configured)
+- **GPIO27** shows FPGA reset control (should stay high during normal operation)
+
+**Note**: GPIO24 and GPIO27 are **output pins** but can still be **monitored** by the Logic Analyzer. The firmware uses universal pin state preservation to maintain their output state while allowing signal capture. **All pin configurations remain unchanged** after capture operations.
+
+### Status LEDs
+- **GPIO13** - Red LED (active-low)
+- **GPIO12** - Green LED (active-low)  
+- **GPIO15** - Blue LED (active-low)
+
+## Clock Configuration
+
+The FPGA receives a **10MHz clock** generated by the RP2040's PIO system.
+
+### Changing the FPGA Clock Frequency
+
+To modify the clock frequency, edit the `fpga_start_clock()` function in `LogicAnalyzer_FPGA.c`:
+
+```c
+void fpga_start_clock() {
+    // Calculate divider for desired frequency
+    // Current: 10MHz = system_clock / divider
+    float divider = (float)clock_get_hz(clk_sys) / 10000000.0f; // 10MHz
+    
+    // For different frequencies:
+    // 5MHz:  float divider = (float)clock_get_hz(clk_sys) / 5000000.0f;
+    // 25MHz: float divider = (float)clock_get_hz(clk_sys) / 25000000.0f;
+    
+    pio_sm_set_clkdiv(pio1, fpga_clock_sm, divider);
+}
+```
+
+## Usage Instructions
+
+### 1. Build and Flash the Firmware
+
+```bash
+# Configure for pico-ice
+cmake -DBOARD_TYPE=BOARD_PICO_ICE ..
+make -j8
+
+# Flash the resulting .uf2 file to your pico-ice
+```
+
+### 2. Connect to Logic Analyzer Software
+
+1. Connect the pico-ice to your computer via USB
+2. The device will identify as "Logic Analyzer (pico-ice)"
+3. Use Dr. Gusman's Logic Analyzer software to connect
+4. The software communicates via USB CDC using escaped binary protocol
+
+### 3. Verify FPGA Operation
+
+Before capturing signals:
+1. Check that your FPGA configuration loaded successfully
+2. Verify the 10MHz clock is present on GPIO24
+3. Confirm CRESETN (GPIO27) is at 3.3V
+4. Ensure CDONE (GPIO26) is high
+
+### 4. Capture Logic Signals
+
+- Configure capture channels in the Logic Analyzer software
+- You can monitor both FPGA I/O and RP2040 GPIO pins
+- GPIO24 (FPGA clock) and GPIO27 (CRESETN) can be captured while maintaining their output functions
+
+## Advanced Features
+
+### Multi-Core Architecture
+
+The pico-ice Logic Analyzer uses both RP2040 cores:
+- **Core 0**: Main Logic Analyzer functionality, USB communication, FPGA management
+- **Core 1**: Available for user applications
+
+**Core 1 is available for custom user code!** You can implement additional functionality on Core 1 while the Logic Analyzer runs on Core 0.
+
+### Universal Pin State Preservation
+
+The firmware implements complete pin state preservation:
+- **All pin states are preserved** during and after Logic Analyzer capture operations
+- **Output pins** (like FPGA clock) maintain their output state and continue driving
+- **Input pins** maintain their input configuration and pull-up/pull-down settings
+- **High-Z pins** remain in high-impedance state  
+- **Core 1 user applications** are completely unaffected by Logic Analyzer operations
+- **FPGA applications** continue running without any pin state disruption
+- Logic Analyzer only **reads** pin states - never changes pin configurations
+
+### Real-time FPGA Monitoring
+
+The Logic Analyzer can capture FPGA signals in real-time while the FPGA continues normal operation:
+- Monitor FPGA I/O signals
+- Debug timing relationships
+- Capture FPGA clock for timing reference
+- Analyze FPGA-to-RP2040 communication
+
+## Troubleshooting
+
+### FPGA Not Configuring
+- Verify FPGA flash is programmed with valid bitstream
+- Check that CRESETN (GPIO27) reaches 3.3V
+- Ensure CDONE (GPIO26) goes high after configuration
+
+### No FPGA Clock
+- Verify CDONE is high before expecting clock
+- Check GPIO24 with oscilloscope for 10MHz signal
+- Ensure Logic Analyzer capture isn't interfering with clock output
+
+### Logic Analyzer Connection Issues
+- Verify USB connection and drivers
+- Check that device identifies as "Logic Analyzer (pico-ice)"
+- Ensure Logic Analyzer software supports the pico-ice variant
+
+## Technical Specifications
+
+- **MCU**: RP2040 (Dual ARM Cortex-M0+ @ 125MHz)
+- **FPGA**: ICE40UP5K (5K LUTs, 128KB BRAM, 8 DSP blocks)
+- **Logic Analyzer Channels**: Up to 24 channels (GPIO0-7, 12-27)
+- **Max Sample Rate**: 100 Msps
+- **Capture Memory**: 32KB buffer
+- **FPGA Clock**: 10MHz (user configurable)
+- **Communication**: USB CDC (escaped binary protocol)

-# Fixing Our Mess 4:30 a.m. of 9/25/2025
-Okay, we are changing goals, because we are just fighting bugs we have created in this project, by letting the AI have way too much freedom.  We have strayed too far from the original code to get a pull request accepted, and introduced new bugs in the process.  We have code that works for the BOARD_PICO_2 which is a very close relative of the BOARD_PICO_2_ICE.  Likewise we have code for the BOARD_PICO which is very similar to the BOARD_PICO_ICE.  This code is at git commit 3fa3703c80d8499cbfeec0e33c5837cf09a08587 which is ahead of our work.  We just need to git diff between the Firmware/LogicAnalyzer_V2/ at 3fa3703c80d8499cbfeec0e33c5837cf09a08587 for the PICO_2, and what we have here to figure out the communication bugs.  We need to closely examine these diffs to determine what is going wrong with the communication between the GUI and the firmware.

-# PRIME DIRECTIVE
- I WANT MINIMAL CHANGES TO 3fa3703c80d8499cbfeec0e33c5837cf09a08587 TO ACHIEVE MY GOALS! This is imperitive to get my pull request accepted, and will introduce minimal bugs, so follow this as the prime directive!

-### Branches I Need
-You will need to create these branches.  Each branch is for a pull request to the original Dr Gusman repository.  The changes on 1 will only be needed if it does not already build on Linux.  Numbers 2 and 3 are each for a seperate board we wish to add to Dr. Gusman's LogicAnalyzer project.
-
-1. build_for_linux  This branch is to be like 3fa3703c80d8499cbfeec0e33c5837cf09a08587, with the only difference that it will build 3fa3703c80d8499cbfeec0e33c5837cf09a08587 for the BOARD_PICO and BOARD_PICO_2 here on Linux, which may not work now.  The only changes that should be made are in the cmake files for this branch and it is possible it builds for Linux already.  If it builds already, we do not need this branch. 
-2. new_pico_ice  This branch will add the pico-ice board to the firmware. We have working pico-ice firmware at 89fd601647d5f81dbd77dcb84df9eda8edc04c79.  The goal here is to make the changes minimal from 3fa3703c80d8499cbfeec0e33c5837cf09a08587, while still having it work for the BOARD_PICO_ICE.
-3. new-pico2-ice  This branch is to be like 3fa3703c80d8499cbfeec0e33c5837cf09a08587, with only minimal changes.  We have working FPGA clock and CRESETN firmware in the pico-ice-wip branch that has issues with the commmunication with the GUI, but the code in 3fa3703c80d8499cbfeec0e33c5837cf09a08587 built for the BOARD_PICO_2 has working communication code.

-## Other Notes
-
-The changes for the pico-ice and pico2-ice are described in the other prompt (firmwareonly_prommpt.md) and you are familiar with them as you have this pico2-ice-wip and for the pico-ice, this 89fd601647d5f81dbd77dcb84df9eda8edc04c79.  I wish to tackle these three repositories in the order they are listed, because I found the pico-ice easier to make work than the pico2-ice.  I really need the pico2-ice for my class, but doing it in small steps is the only way I can see this working.
