Pulse generation on I/O Pins

Hi,

I am using Duet RepRap Pro V0.8.5.

Input voltage for my board is 28V and I am using both PWM Fans.

I would like to generate a single pulse (+5V) on any of the available pins on the board. Using one of the pins on the expansion header might be much easier in this case.

Could any one advice on how to generate a +5V pulse signal on expansion header pins by sending a G/M commands.

Regards
Siva

How critical is the width of the pulse? If it is not critical, you could just use M42 commands to set the pin high and then set it low, perhaps with a G4 delay command in between to define a minimum width for the pulse.

Could you tell me which pin do I have to use?

If you look up M42 in the gcode wiki, it tells you which pins are available for use with M42 on the Duet.
