Detailed Description

PWM IN library for STM32F4xx devices - http://stm32f4-discovery.com/2015/01/library-48-measure-pwm-input-signal-with-stm32f4.

This library allows you to measure PWM input signal (Frequency, Duty Cycle) using TIM peripheral.

- PPx: Pins Pack 1 to 3, for 3 possible channel outputs on timer.

Notes on table above

Not all timers are available on all STM32F4xx devices
All timers have 16-bit prescaler
TIM6 and TIM7 don't have PWM input feature, they are only basic timers
TIM2 and TIM5 are 32bit timers
TIM10, TIM11, TIM13 and TIM14 have only one PWM channel
One timer can measure just 1 frequency and duty cycle at a time!
