4.5 PWM Examples

Many TM4C microcontrollers come with a dedicated PWM module that offers more features and flexibility compared to running a hardware timer in PWM mode. The two PWM examples provided will demonstrate how to configure the PWM peripheral for output and how to use some basic features for adjusting the output.
