I use sprintf for this stuff. This puts the integer variable 'a' converted to text in commands[1].

int a = 24;
sprintf(commands[1],"%d",a);
Serial.println(commands[1]);

I can imagine sscanf or atoi helping, but not really sprintf.
Can you explain, SurferTim?

I'll have a look at that. I have about 80 bytes of space left :slight_smile:

So we'll see what it takes.
