Thanks for the rtos suggestion, but I am looking for hobby servo control code.

Okay, I found the PWM example on the Keil website. It looks like as 
long as I only want to use the PWM timer for hobby servos and not 
mix in true pwm motor control I can set it up with the 20ms interval 
my servos are looking for. Now I just have to see if I can get that 
working behind the scenes with a task in freertos updating the match 
values on an as needed basis.

Thanks,
Michael
