Dear all,

Hai,i'm working on a project using 8951...
i try to put ir remote and 6 push-button (for input) and double pwm to drive 2 motor and 6 7's all in single micro.
The ir is conneted to INT1 and 6 push-buttons are connected to AND gate to INT0 and each are also connected to the rest of the port3 (so whenever there is INT0, i check the port 3 which button is press).
The pwm for motor drive is also generated using interrupt (timer1), the source code is almost similar to Mr. Suzatob Aang' code (http://www.8052.com/codelib/unlimited%20pwm)

THe 7's uses scanning method and activated from interupt timer 1.

Everyting works well when i replace the motor drive with LED (for testing), but when i connect to motor drive L293D and then to DC motor (motor for CD), problems occur..the motor doesn't run.
I have to push the push-button or the remote all the time to make it run...it should be running automatically...
The pwm period is 3mS..

Can anybody give any possible solution?

plz,regards

Leo
