Hi, as i'm very new to PICs and i want to find out more about them I would like to learn how to program them. I found some documentation about some commands that are used by the PIC e.g. 'write program memory' = $02h + data to be written. But in a sourcecode i found some other 16bit codes for those commands and so I'm really confused about it. What I want to do later on is to write my own PIC-Programmer software for some kind of stupid serial-port programmers i build. So if anyone here please could help me finding the required informations I would be very happy. Thanks Stefan p.s.: I hope it becam clear what I meant and sorry for the bad english ;-) -- Sent through GMX FreeMail - http://www.gmx.net
