STAMP-C3 problem with Serial2
-
Hello folks
Using
#include <M5Unified.h>HardwareSerial Serial2(2);
and then
Serial2.begin(115200, SERIAL_8N1,GPIO_NUM_21,GPIO_NUM_20);But can't get Serial2 to communicate.
Switched RX and TX no avail.
Tested the slave with another device : slave works okay.What am I missing here?
Thanks -
Solved
I don't why I have been klinging on to Serial2, it got me in all kind of testing out, but the solution is to use Serial 1.
