That looks nice and simple. If I have troubles with what I've got on hand (the CNC4PC charge pump board) I might try your circuit out. (So if you improve it please feel free to post :) ) Are you running that directly off a parallel port pin or is it buffered/opto-isolated? > Regarding the frequency - yes, the period depends on the thread speed. > It toggles the output each time it runs, so a 1KHz run rate = 500Hz out. So in order to get my CNC4PC charge pump board to work correctly (it relies on a 12.5kHz constant signal) I am going to need to create it's own thread in addition to the servo thread and the base thread? I am thinking this is possible to do, are there any negatives to creating a third thread? I'm still assembling my control enclosure so I can't fire things up to experiment, the backplane isn't quite ready to mount the MOBO yet as I'm still drilling tapping to mount some parts. Would help if my ebay score of contactors showed up...I'd get more motivation to get it done. ------------------------------------------------------------------------- This SF.net email is sponsored by the 2008 JavaOne(SM) Conference Don't miss this year's exciting event.
