Hi Roman! Happy new year for you! ;oD >Hi Alexandre, yes it will work.

Thanks for the input! I bought a little 6 x 2 key, that will key MCLR,= SCL, SDA and 5V in programming. So the clock will stay connected. The= little box will have a 5V supply, 12V supply, PIC programmer and level= shifter RS232<>TTL. So it will be enough for most of my applications. >I have a little setup like this and it's great. >Flip one switch, program, flip it back, device >is running. Who needs an ICE?? ;o) Hehe, nice! Can we share photos and schematics? I'd like to take a look= ;o))) My old 486 Notebook is turning the ultimate PIC development portable= station! ;oD ---8<---Corte aqui---8<---- Alexandre Souza taito@terra.com.br http://planeta.terra.com.br/lazer/pinball/ ---8<---Corte aqui---8<---- -- http://www.piclist.com hint: The list server can filter out subtopics (like ads or off topics) for you.
