Roadmap

0. Extension before release

• modules respect stopping/starting [DONE]
• combined modules reset [DONE]
• speed vs time plot [DONE]
• global module flags bitfield (sizespeed & power optimziation) [DONE]
• increase timer resolution [DONE]

1. Cleanup before release

• define module convenience functions API (null select action) [DONE]
• calibrate timer [DONE]
• global module screen erase [DONE]
• module list redraw on start [INVALID]
• clean up speed builtin & rationalize references to pulse_table [DONE]
  * replace pulse_index detection with module stop/start and global stopped flag [INVALID]
• create global builtins flags (stopped, module switched) [DONE]
• separate signals from the rest of the code [DONE]
• disentangle timers [DONE]
• move all device-specific code to either /avr or /display [DONE]

2. Preparation before release

• hw design docs [DONE]
• hacking guide [DONE]
• define module API [DONE]

3. Pre-release [DONE] (out of order)
4. Release

• assembly tutorial [IN PROGRESS] & vid [DONE]
• examples walkthrough [DONE]
• runtime wheel setting module [DONE]
• move signals out from /modules [DONE]
• move plots & others to /lib [DONE]
• display decimal point [DONE]
• create header files for files to be used by modules [IN PROGRESS]
• separate builtin loggers from displayers in the FS [DONE]
• separate speed display from speed_factor persistence [DEFERRED]
• upload eagle files [DONE]

5. Next release

• make modules/base.c a normal builtin
• expose SPI bus
• dedicated buttons
• dedicated pulse sensors

5. Future

• redesigned board
• size optimization (asm)
• memory optimization (programspace)
• prettifying
• plots merge idling pulses into one blank space
• crank rotation [DONE]
• µSD logging (SPI, FAT, file format)
• sleep mode (stop timers, blank screen), decrease frequency
• replace macros with bitfields in drawing procedures
• plot scaling & labelling [EXAMPLE IMPLEMENTED]
• separate code specific to AVR models from /avr/avr.c [DONE]
• precise external timer
• programmable timers (rewrite stopwatch, svtplot) [DONE]
• GPS/compass
• screen API for different screens
• redesign of number printing API (dec. point, number format, position)
• EEPROM/SD persistence builtin
• total distance module
• example for timer calibration
• clock
