Varying dutycycle

Hi,

I am using cortex-M3. I need to generate a square wave using ADC values. Also i need to change the duty cycle. Already i have used timer program to generate square wave with 16ms of timeperiod. Please help me how to change the program.

Thank You.

What program? What chip?

Could you not just DMA the ADC reading periodically into the timers period or duty registers? Or via and ADC EOC interrupt?
