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
Your subject line is highly deceiving. You obviously have no problems at all downloading files, but rather when you're not downloading any more.
My guess would be that this has nothing to do with software. It's your hardware or your measurement equipment that's showing problems.
thnx for your time Broeker. Actually it was the problem of registration of Uvision3. Once i got it registered, it all started functioning right. thnx for your help
