[Product Revision] Stepper Driver with AtomS3 support (& other improvements)

  • C

    • Add a STM32F0 that communicates via I2C
    • Move RST, FLT, EN & VIN(sense) (G39/G38/G5/G8) to STM32F0
    • (Optional) Add port with 4 external Digital I/O pins using spare STM32F0 pins (for limit switches & accessory triggers)
    • (Optional) Add Grove Ports (I2C pass-through using G38/G39 & Generic using G5/G8)

    I had difficulty getting that module working, even on my AtomS3 Lite, the example Arduino code didn't work (and didn't even use all the connected pins). I had to use the schematic & datasheet to adapt AccelStepper to work with it. It would be nice if they moved the extra pins to I2C (and had them in the right state at startup so it actually works).
