Hello. I user Arduino IDE. I have ESP32-S2-Saol-1RI with integration USB port. I try to connect USB device, rfid card reader, and send hex data to it.
I connect:
D+ --> GPIO 20
D- --> GPIO 19
VCC --> v5
GND --> GND
But can't found any information, how to send hex data to it? Can anyone help? Thanks!
