Compiling for esp32c3 #27

Open bronzeblood opened 7 months ago

bronzeblood commented 7 months ago

What parameters need to be changed to use it with the advanced pcb that @davidebeatrici designed. I can get it to compile but the esp just boot loops.

bronzeblood commented 7 months ago

ok i got it to compile by replacing the old section in the project yaml with this..

esp32:
  variant: ESP32C3
  board: esp32-c3-devkitm-1
  framework:
    type: esp-idf

Also add these lines to the main.yaml file

esphome:
  platformio_options:
    board_build.flash_mode: dio

Seems like my boot loop was caused by low voltage from the usb uart i was using, when powered from the inverter its starting fine.

However i'm not getting any communication, can someone clarify the gpio pins used for tx/rx on the advanced design.

bronzeblood commented 7 months ago

Figured it out 

  inverter_tx_pin: GPIO7
  inverter_rx_pin: GPIO6

When using the advanced pcb

All seems to be working fine, maybe this will help anyone that makes the advanced pcb in the future.

Thank you for using my advanced PCB!

For reference, it was added in #10. Please note that I've been using arduino as framework type without setting the flash mode, but it's probably more correct to use esp-idf since it's the official Expressif framework.
