Non-STM32 reference signals found in existing code

These rows are not STM32 pins. They are the actual motor-control pin/peripheral evidence found in the available C2000/Simulink source and should be used only as a migration checklist.

TODO for STM32G474CEU6 migration

Add the real STM32 project files, then regenerate this document from:

  • .ioc: pin names, peripherals, AF selections, ADC channels, DMA, timers.
  • Core/Inc/main.h: GPIO aliases and active-level macros.
  • Core/Src/gpio.c, adc.c, tim.c, usart.c, fdcan.c, spi.c, i2c.c: init functions.
  • Core/Src/stm32g4xx_hal_msp.c: MSP GPIO AF and DMA binding.
  • .uvprojx: included source tree and target device.
