Hi Michael, It would be really good to understand your application a little more so that any specific needs that you have may be met. In the meantime, I would also suggest searching on ni.com for "pwm" or other keywords that relate to your application. You will see a faceted navigation on the left side that allows you to narrow your search for example code, tutorials, etc.Please post back with more information and the community will be able to help out with suggestions.<a href="http://search.ni.com/nisearch/main/p?q=pwm&x=0&y=0" target="_blank">ni.com search for "pwm"</a>
