Obegränsad which pin for brightness? #1

Hi @phiten,

In your config for Obegränsad there's GPIO14 set for brightness control, but where to connect this to the matrix board?

Is this right?

    latch_pin: 12 # CLA
    clock_pin: 04 # CLKDI
    data_pin: 05 # IN

Maybe for esp8266_pwm we use pin labelled EN? Can we use ledc if we have ESP32?

Yes brightness is on the EN pin. On esp32 ledc should work but haven't tested that yet.

ledc works like a charm
