 -2 Off-Topic		 #101249 - write PID sotfware for mcs51 micro.
Responding to: ???'s previous message
i am studying PID controllers of microcontrollers but unlucky!Because i have to do PID software for 8051 microcontroller to help me graduate from a university in year 2006!
Anyway i also feel so difficult about my subject i am doing for 8051 while i don't have very much document in this areas.And so i cannot do better now! i hope i am hoped with others arround me with "source code,flow chart+schematics+tutorials"for example.At that time,i can try my best to pass myself if you guys help me!
Please help me if you can!
Thank you before because you read my e_mail!
