Hey guys! What are your views on Software based PWM. I can create multiple timers in my C# application and allow user to select the time interval of the timers and hence, the frequency and the duty cycle. The software timers will transmit some bits once they reach their threshold value and will turn a Pin ON/OFF. I will test the output tomorrow on a Scope as well to determine the accuracy.

 

I tried making a simple protocol for the data transfer.  A 10 bit packet is transmitted from the GUI which determines the control. I am having some timing issues and to remove these, i will need one of the timers in the MSP430g2553 device making only 1 timer available for the PWM. I am working on making the same GUI function for Stellaris/TIVA C Launchpad as well.
