Add RMT LED support #15

Closed jetpax closed 10 months ago

jetpax commented 10 months ago

This PR adds support for an addressable LED eg as fitted to the ESP Devkit-M

It displays diag codes , eg blink twice during wifi connect, blink once when connected

It uses the espressif/led_strip: "^2.5.2" managed component

The color/brightness can be changed by issuing a command like

{"type":"request","target":"rmtled","name":"color","data": [0,128,0]}

to set the LED to green with half brightness

To enable it, pass the desired pin to the constructor in main eg

dev::useRmtled(GPIO_NUM_48);

Thank you, @jetpax, do we really need espressif__led_strip in CMakeLists.txt? I believe adding dependency to esp32m/idf_component.yml is sufficient, can you check?

jetpax commented 10 months ago

Wouldnt compile for me without it, but maybe there is another way I am not aware of?

dyarkovoy commented 10 months ago

Okay, I tried to compile it on my end and I see the problem. The component needs a "public: true" declaration in idf_component.yml:

  espressif/led_strip:
    public: true
    version: "^2.5.2"

Please try to compile with this change and with espressif__led_strip removed from CMakeLists.txt, it seems to be working for me

Good catch, works fine for me too.
