</div>They’re quite processor-power hungry. As I understand it, the timing requirements are very tight. If the control signals are generated by bit-banging, the processor can’t do much else while LEDs are addressed. Some processors have PWM outputs that can be mis-used to generate the signals, but this looks like an ugly hack to me.<br>
