PWM Timer Calculations Spreadsheet

[jgschmidt]

While working on a PWM application I struggled with datasheets, application notes and forum topics to arrive at the correct parameters for the CCS statements that control the PWM hardware. I also wanted to capture what I learned since I would probably forget it by the time I needed it again, so I developed a spreadsheet that produces the actual statements you need to include in your program. This was featured in the June 2010 issue of Servo Magazine. The article and spreadsheet are on my website at www.jgscraft.com/ledpwm.

Here is an example of the code the spreadsheet produces for a PWM frequency of 16KHz on a midrange PIC running at 8MHz.

Great work!
I plan on using this for several projects in the future.
Having run through several scenario, it looks accurate to me.

Thanks for the feedback.
