Yes, this LED is connected to GPIO 38, but I am not using the pin.

I was testing the pins one by one and the problem was pin 48, but I don't know why.

Hello. I am using the ESP32-S3-DevKitC-1 board, but apparently I connected something wrong or some statement, since the LED that comes on the board turns on white, sometimes at the beginning it turns green. What could be the problem? It is worth mentioning that I have it mounted on a PCB, so it is d...

Hello, I have a problem with the implementation of the PxMatrix library on the esp32-S3. Specifically in the definition of the SPI pins. In the library code snippet I start the definition of the SPI bus: spi_t * spi = SPI.bus(); // reg_value = 0x1234; debug for(int i=0; i<47; i++) SPI_2BYTE(reg_valu...

Hello, I have been trying, without much success, to connect an ESP32-S3-DevKitC-1U to an LED dot matrix, with the help of the video: https://www.youtube.com/watch?v=Nkhmpz1rV78&t=234s where they use the mdm32 library: https://github.com/Qudor-Engineer/DMD32 I guess my problem lies in the definition ...

Thank you very much for your answer. I'm a little new to this and would like to go deeper, but from what I understand you're telling me that by using the GPIO matrix, can I assign functions to any pin? If so, how would the programming be, for example, if I want a pin to be MOSI, how would I do it? I...

First post I've made in my life, I hope it can help me. I am working with the esp32-S3 board, I need to use SPI and I2C communication, but I cannot find the pins related to these. I understand that in GPIO35-36-37 there is SPI communication (of the two available), but it does not explain the MOSI, M...
