TIMER Extended features

The Timer Extension features include:
1. Complementary outputs with programmable dead-time for :
2. Synchronization circuit to control the timer with external signals and to interconnect
several timers together.
3. Break input to put the timer output signals in reset state or in a known state.
4. Supports incremental (quadrature) encoder and hall-sensor circuitry for positioning
purposes

How to use this driver

1. Initialize the TIM low level resources by implementing the following functions
depending from feature used :
2. Initialize the TIM low level resources :
a.
b.
3. The external Clock can be configured, if needed (the default clock is the internal clock
from the APBx), using the following function: HAL_TIM_ConfigClockSource, the clock
configuration should be done before any start function.

Output Compare
PWM generation (Edge and Center-aligned Mode)
One-pulse mode output
Complementary Output Compare : HAL_TIM_OC_MspInit()
Complementary PWM generation : HAL_TIM_PWM_MspInit()
Complementary One-pulse mode output : HAL_TIM_OnePulse_MspInit()
Hall Sensor output : HAL_TIM_HallSensor_MspInit()
Enable the TIM interface clock using __TIMx_CLK_ENABLE();
TIM pins configuration
Enable the clock for the TIM GPIOs using the following function:
__GPIOx_CLK_ENABLE();
Configure these TIM pins in Alternate function mode using HAL_GPIO_Init();
