Re: Multiplexing LED
1. 16x1 led.
2. actually, is not flickering, but is not as bright as i want.
3. just using any pic, with timer 0 enabled and every interrupt i change the pin that drives the next led.
dc servo pulse-direction input
OK, i have mach3 software... and now i want to convert the output of mach3 (for steper motors) to servo motors. Do you have any idea how can i do that?.

Everybody knows that every CNC software controls Steper motors with pulse-direction instruccion.
Can someone give me an idea to convert pulse-direction instruccion to a Servo instruccion, like speed... position, etc?.
