STM32 Timer PWM Input Capture

The timers in STM32 MCUs are incredible powerful. We have used them before to generate PWM Signals and to decode signals from rotary encoders. In this example we will use them to determine frequency an duty cycle of an external PWM signal.

For the example we will be using a Black Pill development board and we will be using the same MCU to both generate and to decode the PWM signal.

The source of the complete example is here.
