Re: Noob question: how to send and receive bytes over USB?

Where should I look to fill in the parameters to machine.UART constructor? There's a UART id, "rx" and "tx" values. I understand that "rx" and "tx" correspond somehow to wires, but don't know more than that ....

On the m5stack side I've tried from machine import UART import utime uart = UART(1, tx=22, rx=21) def main(): while True: msg = uart.readline() pr...

Help with m5stack project (willing to pay)

I'm trying to make a toy Bitcoin wallet using an m5stack ESP32 microcontroller. I have this fork of loboris' firmware: https://github.com/justinmoon/MicroPython_ESP32_psRAM_LoBo. I added one commit which attempts to hook up 2 libraries containing cryptographic primitives and their MicroPython bindin...
