Hello People, this is my first thread here. I just want to ask here, what does a programmer do to program a controller, actually i want to make a programmer my self, dont want to copy it from any site. please help me to understand this phenomenon.
Thanks.
Regards, Asad Raza
What i mean to ask is, how a controller is programmed? what conditions required for the controller pins , or what voltage to what pins we povide so that it is programmed. NOBODY can answer you in a general way. for chip a it is ... for chip b it is ... for chip c it is ... not even two different chips from the same manufacturer may program the same way
If i give it up to in making a programmer, but can any body tell me what is the process?????? drop the if

I mainly work on AT89c51, i am intrested in this controller.. Now If someone has an idea, then direct me to that one.
if you insist on supporting Bayer (the manufcturer of Aspirin) go to 8052.com and do a search on 'kitchen table programmer'.
You will find some OLD threads that discuss kitchen table programmers and (although I doubt it) you may find a thread that ends with 'success'. I know there are references to some web published programmer(s?) with "why can I not get it to work".
Again, be nice to yourself, DO NOT GET INTO THIS QUAGMIRE, switch to modern chips where a 'programmer' cost you nothing (UART types) or $25 (SPI types) or $30 (JTAG types)
Since this topic has nothing whatsoever to do with Keil, that would be a more appropriate place anyhow!
