FastLED support #165

Open materight opened 1 year ago

materight commented 1 year ago

I'm trying to build an ESPHome image for a bk7231n device that controls an addressable LED strip. So I've added this component:

light:
  - platform: fastled_clockless
    chipset: WS2811
    pin: P17
    num_leds: 43
    rgb_order: RGB
    name: light

when I try to build it, I first get:

Internal Error: require_framework_version does not support this platform configuration
    platform: bk72xx
    framework: arduino

I assumed it was just a missing check, so I added a condition for CORE.is_libretiny here and recompiled, but I get this:

Is FastLED not supported yet or am I missing something?

kuba2k2 commented 1 year ago

It is not supported. FastLED needs a platform compatibility layer for each supported microcontroller. Apparently ESPHome uses FastLED version older than 3.3.3, which assumes every other platform than supported is AVR:

#elif defined(ESP32)
#include "platforms/esp/32/led_sysdefs_esp32.h"
#else
// AVR platforms
#include "platforms/avr/led_sysdefs_avr.h"
#endif

Normally, you should get an error stating that this platform is not supported.

Ah thanks for the clarification. So I guess adding support for it depends on the FastLED team?

kuba2k2 commented 1 year ago

That, and supporting the appropriate protocols in LibreTiny.
