add m5stamp-c3 board

[jcgruenhage]

fixes #670

I have never done this before, so if I'm doing this very wrong, please tell me. I have not found any documentation on how to do this though.

I've based this on the esp32-c3-devkitm-1.json board, most stuff is unchanged.

After some help on the ESPHome Discord, I've gotten this to work. The now updated version of this PR successfully boots into ESPHome using the following config:

esphome:
  name: m5stamp-c3

esp32:
  board: m5stamp-c3
  variant: esp32c3
  framework:
    type: esp-idf
    platform_version: https://github.com/jcgruenhage/platform-espressif32#m5stamp-c3

logger:
  level: DEBUG

Is there a way to manually include this until it is merged and released?

[pho3nixf1re]

I managed to figure this out (I think, not fully tested) by following the instructions here on creating custom boards. Hopefully it works. Would be really great if this could be merged officially.

[pho3nixf1re]

Is it possible for this to support Arduino? This board supposedly does.

[jcgruenhage]

I'll play around with that, we'll see.

[jcgruenhage]

jcgruenhage@34858df works, but it's not based on develop, but on feature/arduino-upstream, (which seems not to have been merged since I started working on this back in February).

[pho3nixf1re]

Hm, thanks for checking on this. I may just stick with the esp framework then.

any updates on merging this pull request?

[Jason2866]

Please use mode qio Board does support

[jcgruenhage]

iirc I changed it to dio after qio didn't work, but I can still change it back and test it when back in reach of one of these boards

[Jason2866]

Yes, dio was needed for core < 2.0.4. Was a bug in bootloader generation.

[jcgruenhage]

I have pushed that, although I wasn't able to validate it yet because I'm using the commit based on the feature/arduino-upstream branch, which doesn't seem to have been worked on recently? Arduino support is quite important to me..

Hi, any progress on this? I'm trying to use this PR with arduino framework.

[jcgruenhage]

I've rebased this and this is working for me, including arduino support:

esphome:
  name: ${device_host}
  platformio_options:
    platform_packages:
      - framework-arduinoespressif32 @ https://github.com/espressif/arduino-esp32.git#2.0.14
    platform:
      - https://github.com/jcgruenhage/platform-espressif32.git#m5stamp-c3
  on_boot:
    then:
      - light.turn_on:
          id: "${device_id}_led"
          red: 80%
          green: 0%
          blue: 100%

esp32:
  board: m5stamp-c3
  variant: esp32c3
  framework:
    type: arduino

binary_sensor:
  - platform: gpio
    pin: 3
    name: "${device_name} Button"
    id: "${device_id}_button"
    on_click:
      then:
        - light.toggle:
            id: "${device_id}_led"

light:
  - platform: neopixelbus
    id: "${device_id}_led"
    type: GRB
    variant: SK6812
    method: ESP32_RMT_1
    num_leds: 1
    pin: 2
    name: "${device_name} Led"

Can we finally get this merged? It's been nearly two years now.

@valeros Board is supported in Arduino espressif32 https://github.com/espressif/arduino-esp32/blob/master/variants/m5stack_stamp_c3/pins_arduino.h

[valeros]

@Jason2866 This variant is not available in the latest stable 2.0.14. Furthermore, it seems that the m5stick_c variant was renamed to m5stack_stamp_c3, but these are two different boards, aren't they?

[Jason2866]

Ahh, yes board m5stack_stamp_c3 is added in Arduino master. The board m5stick_c was renamed to m5stack_stickc.
Oh my this boards mess, who ever thought it is a good idea to set boards specific settings via a boards name....

Is there work done or planned to add a boards settings generator? Not just for espressif boards, a general solution?

Most issues here and for users is this boards mess...

[lboue]

Could you validate this request?

[jcgruenhage]

@valeros Board is supported in Arduino espressif32 espressif/arduino-esp32@master/variants/m5stack_stamp_c3/pins_arduino.h

I just checked the arduino-esp32 repo again, and it's still not in any release yet. There are release candidates for 3.0.0 though, which do contain the board.
