Using Matter light example to control onboard addressable LED for esp32c6 (CON-1054)

[julesrodrigues11]

I was working with the light example available on the esp-matter repository on the esp32c6 board. I have been trying to make it such that the power button would toggle the addressable LED on board the esp32c6. To this extent, I studied the blink example that is available in the esp-idf repository, and was working on merging the code together. However, I wasn't quite achieving the result I wanted. How would I go about doing this? Many thanks for your time in advance.

Hi @julesrodrigues11, I am so sorry, we found the issue in light example in esp-matter when you use esp32c6. There is bad pin for BOOT selected, it should be GPIO9: CONFIG_BSP_BUTTON_1_GPIO=9.

And should be changed this (all occurrences in the file):

Hi @espzav , many thanks for your reply. I'm going to implement the changes shortly and test it out. I assume the value of CONFIG_BSP_LEDS_NUM=1 would be correct in this case then. Is that correct? Or what should it be instead?

[espzav]

Yes, this is right settings:

# ESP32-C6-DevKitM-1 Settings
# Buttons
CONFIG_BSP_BUTTONS_NUM=1
CONFIG_BSP_BUTTON_1_TYPE_GPIO=y
CONFIG_BSP_BUTTON_1_GPIO=9
CONFIG_BSP_BUTTON_1_LEVEL=0
# LEDs
CONFIG_BSP_LEDS_NUM=1
CONFIG_BSP_LED_TYPE_RGB=y
CONFIG_BSP_LED_RGB_GPIO=8
CONFIG_BSP_LED_RGB_BACKEND_RMT=y

I've managed to get the light working now. Not exactly how I wanted it, but I'll tinker around with it a bit more and I think I should get it working soon. Many thanks! On another note, is there any documentation with regards to the config settings that can be studied to understand what is correct and what is not.

The fix is merged to Github with bed4aa9. Closing this issue. @espzav Can you please check the above question around the documentation. Thanks!

@julesrodrigues11 Here is documentation for Generic BSP, which is used there: https://github.com/espressif/esp-bsp/tree/master/bsp/esp_bsp_generic
