I trying to build a slave flash trigger for a digital camera.
with a programmed 12f629.
need a little help with the code.
digital cameras have 1 or 2 preflashes before the main flash.
using a photodiode to trigger a input to GPIO.2 I'm thinking if I can program it to ignore the first 2 flashes and give a output on GPIO.4 to fire the slave flash on the 3rd. it mite work.
what little programming I can do is with PBP and CDlite.
can anybody give me A jump start. Thanks
