So over all this is for a CNC machine I am adding a 3d printer extruder and hotplate. I have got my arduino PID controller to work for the heaters. Right now Im just trying to display my temp and set temp.
Now, this code is no where near done but I only need help on adding letters. It allows me to display BEEF, all other letters dont work. I want to display any letter that will show on a 7seg, or the ability too.
Then my only other goal is to display a letter prior to my temp/set readings. Meaning a letter prior to a variable. for example C237 or S278.
Thanks in advance

void setup() {
#ifndef __AVR_ATtiny85__
Serial.begin(9600);
Serial.println("7 Segment Backpack Test");
#endif
matrix.begin(0x70);
}
void loop() {
If(POTCount != PrevPOTCount){ // this will be an average count of mutiple readings for hysteresis
matrix.print(0xBEEF, HEX); // Want BEEF to Say ADJ or any other letters, only B,E,and F work
matrix.writeDisplay();
delay(500);
// print a floating point
matrix.print(setPoint); //this will be POT temp set point But Iwant a letter prior to temp setting
matrix.writeDisplay();
delay(5000);
}
if(POTCount == PrevPOTCount){
matrix.print("C",Temp); //this will be current temp set point but I woulld like a C before my 3 digit C temp
matrix.writeDisplay();
delay(100);
}
}
