Random Code
- Writing an arbitrary number of bits to pins
byte pins[] = {2,3,4,5,6,7}; byte totalPins = 6; void setup(){ for(byte a = 0; a < totalPins; a++){ pinMode(pins[a], OUTPUT); } } void writeData(byte data, byte numberOfBits, byte startBit){ for(byte a = startBit; a < numberOfBits; a++){ if((data >> a) & 0x01){ digitalWrite(pins[a], HIGH); }else{ digitalWrite(pins[a], LOW); } } }
