29 ##### TIMER Extended features #####
30 ==============================================================================
31 [..]
32 The Timer Extended features include:
33 (#) Complementary outputs with programmable dead-time for :
34 (++) Output Compare
35 (++) PWM generation (Edge and Center-aligned Mode)
36 (++) One-pulse mode output
37 (#) Synchronization circuit to control the timer with external signals and to
38 interconnect several timers together.
39 (#) Break input to put the timer output signals in reset state or in a known state.
40 (#) Supports incremental (quadrature) encoder and hall-sensor circuitry for
41 positioning purposes
42 (#) In case of Pulse on compare, configure pulse length and delay
43 (#) Encoder index configuration
44
45 ##### How to use this driver #####
46 ==============================================================================
47 [..]
48 (#) Initialize the TIM low level resources by implementing the following functions
49 depending on the selected feature:
50 (++) Hall Sensor output : HAL_TIMEx_HallSensor_MspInit()
51
52 (#) Initialize the TIM low level resources :
53 (##) Enable the TIM interface clock using __HAL_RCC_TIMx_CLK_ENABLE();
54 (##) TIM pins configuration
55 (+++) Enable the clock for the TIM GPIOs using the following function:
56 __HAL_RCC_GPIOx_CLK_ENABLE();
57 (+++) Configure these TIM pins in Alternate function mode using HAL_GPIO_Init();
58
59 (#) The external Clock can be configured, if needed (the default clock is the
60 internal clock from the APBx), using the following function:
61 HAL_TIM_ConfigClockSource, the clock configuration should be done before
62 any start function.
63
64 (#) Configure the TIM in the desired functioning mode using one of the
65 initialization function of this driver:
66 (++) HAL_TIMEx_HallSensor_Init() and HAL_TIMEx_ConfigCommutEvent(): to use the
67 Timer Hall Sensor Interface and the commutation event with the corresponding
68 Interrupt and DMA request if needed (Note that One Timer is used to interface
69 with the Hall sensor Interface and another Timer should be used to use
70 the commutation event).
71 (#) In case of Pulse On Compare:
72 (++) HAL_TIMEx_OC_ConfigPulseOnCompare(): to configure pulse width and prescaler
73
74
75 (#) Activate the TIM peripheral using one of the start functions:
76 (++) Complementary Output Compare : HAL_TIMEx_OCN_Start(), HAL_TIMEx_OCN_Start_DMA(),
77 HAL_TIMEx_OCN_Start_IT()
78 (++) Complementary PWM generation : HAL_TIMEx_PWMN_Start(), HAL_TIMEx_PWMN_Start_DMA(),
79 HAL_TIMEx_PWMN_Start_IT()
80 (++) Complementary One-pulse mode output : HAL_TIMEx_OnePulseN_Start(), HAL_TIMEx_OnePulseN_Start_IT()
81 (++) Hall Sensor output : HAL_TIMEx_HallSensor_Start(), HAL_TIMEx_HallSensor_Start_DMA(),
82 HAL_TIMEx_HallSensor_Start_IT().
