Hello everybody,
I d like to share some of my routines which are based upon Neutone s ideas.
We use this code in our welding machines successfully for more than 2 years now.
The protocol is built like this: Firstly the MASTER scans the bus to find out what SLAVE(S) is/are present in the system. Its behaviour (commands issued to particular SLAVES) depends on the results of this scanning process. The main loops in all members must be designed so that they take 1 msec because all bus timings (end of fr a me recognition) rely on that. The advantage is that no other timers are needed for the communication.
The code will run on PIC16F877@20MHz or PIC18F452 and it s been compiled with PCM or PCH 3.190
Well, let s start with MASTER main part
