Hey yo steve and darrel,

It's working.I add some config on the inc file (STACK OVERFLOW & LVP OFF)(and that's weird too why that thing come in my way?) and it's working.So do goes for the SPI.It never jump to main loop this time.Thanks a lot guys.I safely blinked the LED'S this time.Talk about screen saver polling LPT's,geee..that's freaky.Lucky for me,i disable screen savers as i hate one =>.But the flourescent,is that for real?.Cuz i do work or test anything i do with my only one table lamp thats couple of inches away from my project desk.I don't face that kind of problem and especially 'resets' on pic?.Hmm..for sake i gotta bear in my mind.But i face a 50hz distortion ( using fluke dmm) but i knew that's a AC current nearby but i do re-calculate.Beside,the nature of flourecent driver (balast ,starter e.t.c) is more toward crude stuff.
