I'm basically trying to do this: https://www.instructables.com/id/Interf ... -pySerial/

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 ....

(I also posted on Loboris' forum) I'm using loboris' fork with an m5stack. I'm trying to send bytes to and receive bytes from the device using PySerial. 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...

That worked!

Thanks a ton. I sent a donation. Keep up the great work

That's right. I added leading underscore to "aes_encrypt" and "aes_decrypt" definitions in MicroPython_ESP32_psRAM_LoBo/Tools/esp-idf/components/wpa_supplicant/src/crypto/aes-internal-enc.c and MicroPython_ESP32_psRAM_LoBo/Tools/esp-idf/components/wpa_supplicant/src/crypto/aes-internal-dec.c respect...

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...
