Hi all, i have a question. Is it possible to use the PWM module of PIC16f877a as a D\A converter just by varying the duty cycle ?
for eg. 2.5v = 127 duty cycle
and the output is connected to a simple two pole RC filter.
What are the values of R and C do i have to use ?
How fast is the conversion speed?
Your help is much appreciated.
