>I can reasonably easily repurpose a VFD display interface board of ours (w= ith an onboard FPGA and 5V level translators) to reconfigure the strobe to = whatever duration I want... probably 50 microseconds? The delay that way w= ould be very minimal and low jitter. How about a simple 555 circuit? An FPGA seems a bit of overkill to generate= one pulse :-) - - Bob Ammerman RAm Systems --=20 http://www.piclist.com/techref/piclist PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist .
