I have a ADuC7026 Evaluation Kit. I have written a program that generates a PWM signal in three different cases (each case has a different duty cycle for PWM). Program works fine while in debugging mode but as soon as i disconnects the kit from PC (via USB port), the signal level drops plus signal starts shaking.
I even tried to download hex file via serial link cable to the controller but result is same i-e as soon as i disconnects the serial link the voltage level drops.
Plz Help
