It's straight forward and easy to extend.

I'm super green with coding Arduino's. But I started with FilePhil's code and couldn't get Artisan to talk to it using TC4. I made a simple modification that got it working very reliably and not needing power resets. Seems the code needed the serial port initialized and baud rate defined. So I stripped out all but what is necessary from FilePhil's code and attached my sketch below.
//TC4 Emulator.ino
bool unit_F = true; //true = °F - false = °C
double tempA=200;//ET Temp
double tempB=300;//BT Temp
//Parsing Serial Commands
void handleSerialCommand(){
if (Serial.available()>0){
String msg = Serial.readStringUntil('\n');
if (msg.indexOf("CHAN;")== 0){ //Ignore this Setting
Serial.print("#OK");
}
else if (msg.indexOf("UNITS;")== 0){
if (msg.substring(6,7)=="F"){ //Change to Farenheit
unit_F = true;
Serial.println("#OK Farenheit");
}
else if (msg.substring(6,7)=="C"){ //Change to Celsius
unit_F = false;
Serial.println("#OK Celsius");
}
}
else if (msg.indexOf("READ")==0){ //Send Temps
Command_READ();
}
}
}
//Send Data
void Command_READ(){
Serial.print("0.00,");
Serial.print(tempA,4);
Serial.print(",");
Serial.print(tempB,4);
Serial.println(",0.00,0.00");
}
void setup() {
// initialize USB serial
Serial.begin(115200);
while (! Serial); // Wait untilSerial is ready
}
void loop() {
handleSerialCommand();
}LMWDP #671
