Accessing second UART on M5Stamp-PICO
-
Is there a way to access a second hardware UART on the M5Stamp-PICO?
I do not need the SPI port but I do need the UART (and I2C) and uploading code while also using the UART in the application is really inconvenient.
Any help appreciated. -
Hello @didier9
for UART you should be able to use any available GPIO for RX and TX like this:
Serial2.begin(115200, SERIAL_8N1, <RX>, <TX>);for I2C you should be able to use any available GPIO for SDA and SCL like this:
Wire.begin(<SDA>, <SCL>);Thanks

Hi Felix,
Sorry for the delay... my STAMP_PICO project was momentarily shelved but I just resurrected it and found your response.
I will definitely try your suggestion since I would like to keep the native port to flash but I need another UART.
Thank you!
