Overview

FlightPanel-01 is a custom input controller based on the ATmega32U4 (Arduino Pro Micro compatible). This project serves as a bridge for migrating an older design into a new, consolidated prototype. It features a high-density input matrix using a 16-channel multiplexer to support a variety of flight simulation controls.

Hardware Specifications

• MCU: ATmega32U4 (TQFP-44)
• Multiplexer: CD74HC4067M (16-Channel Analog Mux/Demux)
• Inputs:
  • 8x Toggle Switches (via Mux)
  • 11x Tactile Push Buttons (8 via Mux, 3 direct)
  • 1x Rotary Encoder with Push Button (direct)
  • 3x Potentiometers (Analog)
• Outputs:
  • 4x Cathode-driven LEDs (PWM capable)

Project Status

This repository is currently in the prototype and migration phase. The schematic and initial PCB layouts are being refined to ensure compatibility between legacy code and the new hardware architecture.
