i want to have ra3(pin 1) on 16f84a alternate high and low at 30 second intervals to control motor direction through an lmd18200. can someone give me code for this? thanks
Hi everyone: Am doing MS project on SRM. Using PIC16F877 as the controller. need to find out how I will accelerate and decelerate the machine. Cannot simply increase/decrease the switching freq. Need to implement a PI controller digitally. At the same time need to change between current chopping regulation (using chopping strategy) and single pulse operation as the machine speeds up. Say up to 1500rpm current chopping and above this single pulse operation.At very high speeds need to advance the switching angle. Hard stuff I have. Anyone knows anything e-mail to email@example.com pls... Cheers.+
