Reply to "Arduino TMCC signalling"

Glad it worked!

If the TMCC receive test is successful, you can try transmitting a very simple 3-byte TMCC command - the emergency stop command (FE FF FF).  Get something running on your layout, then run this program (again assuming the serial adapter is connected to Serial1:

#define TMCCPort Serial1

void setup() {
Serial.begin(115200);
Serial.println("E-stop test starting");
TMCCPort.begin(9600);

TMCCPort.write(0xFE);
TMCCPort.write(0xFF);
TMCCPort.write(0xFF);

}

void loop() {

}


If successful everything TMCC on the layout should shut down.
