I bought a couple of Arduino Nano ESP32 boards. I look at the schematic and I don't see what I might be doing wrong. I cannot get the Red LED in the RGB LED to turn on. I know it is active low. The Green and Blue work fine. I am using Legacy PIN mode for my sketch. I have tried LED_RED and 46. Nothing seems to work. This has been across multiple boards and programming it from both Linux and Windows. Is there something in the schematic I am just missing? It isn't a huge deal, but I wanted some status and the Red helps with that.
I used blink again, thought I had done this before. I used both Arduino Pin Mappings and Legacy Pin (GPIO). Both worked. It must be with a library I am using that is inhibiting this for me. I will look at the OneWireNG library I am using for a temperature sensor. I don't have any other library being used with this sketch.
happens the same to me when working in pin legacy mode. if i revert to default pinmode, everything is ok. What is worse is that macros D14, D15 and D16 are not supported (which are the ones we should be using ofr rgb led).
found the answer in another question: LED_RED , LED_GREEN, LED_BLUE macros are working
Why not share what you found?
I found my issue was when I had copied and pasted, I missed the pinmode assignment for the RED LED. That was my issue with the original code base I had started with. After that is worked fine.
