Esto funciona perfectamente, pero estoy interesado en implementar el control RGBW, que requerirá un cuarto canal.
Por lo tanto, asumí que tendría que cambiar el número de LED de 3 a 4 bajo la aplicación PDM_DIMMED_LAMP, asignar un pin al nuevo LED, actualizar el número de ranuras relevantes en la aplicación DMX512 de 3 a 4, agregar un nueva línea en el código para recopilar datos de 8 bits para el nuevo LED (estoy usando la parte AZUL en el segundo LED RGB como soporte para el blanco) y luego ejecuto el código.
Sin embargo, cuando cambio el número de ranuras relevantes de 3 a 4, los 4 canales se iluminan pero dejan de responder al atenuador.
¿Podría ser esto un problema de atenuación?
Si alguien tiene alguna sugerencia acerca de por qué esto podría estar sucediendo, sería muy apreciado.
