Need one output pin #68

Open borkog opened 1 week ago

borkog commented 1 week ago

Hi, I need T-RGB to work as slave with Raspberry PI (PI as a master)

But I need one single output pin on T-RGB as an interrupt for communication slave->master (to trigger RPI to read slave)

I don't plan to use SD card ... I see that ESP_SD_MISO is connected to GPIO38 ... is it safe to pluck that pin from the SD card slot and use it?

Thanks, B

It is possible to use it that way because the board only has one SPI device. If you use it this way, be careful not to damage the PCB.
