I am trying to controll 2 dc motors with the pic16f877.
when i let one motor turn it will work fine but when i let them both run the both motors wont turn, in flowcode it works perfect.
Can someone help me with this ?
Thanx.

Re: Rs232 pwm controll motors
Hello
If you have the LCD component connected then you can print out the RS232 values to the display to ensure that the values are being received correctly. The program looks ok to me but I cannot test the comms side of things so this could be the cause of the problems. Do you have an LED or something similar that you can drive directly from output CCP2 to test that the motor is not at fault.

Re: Rs232 pwm controll motors
By the names you have given on your LEDS, I am assuming your trying the pan tilt head route. You have initialised 2 PWM outputs assuming one for pan, one for tilt.. Your program is only showing one PWM(0) output. This may be your problem.
