I am currently trying to establish a serial connection between a e-paper and a ESP32-WROOM-32U on a ESP32_Devkitc_V4.
I connected cables to TX and RX pins on the ESP32 and created the following code :
Code: Select all
soc = UART(1)
soc.init(rate, timeout=5000, tx=1, rx=3)
...
soc.write(cmd) #cmd is a string
Unfortunately, i get this in green in the console (i think it's a system output):
Code: Select all
I (8647) uart▒A500090ACC33C33Ca6
After this, the program totally freezes and I have to reboot with the reset button ...
Anybody have an idea ?
