36 ##### TIMER Generic features #####
37 ==============================================================================
38 [..] The Timer features include:
39 (#) 16-bit up, down, up/down auto-reload counter.
40 (#) 16-bit programmable prescaler allowing dividing (also on the fly) the
41 counter clock frequency either by any factor between 1 and 65536.
42 (#) Up to 4 independent channels for:
43 (++) Input Capture
44 (++) Output Compare
45 (++) PWM generation (Edge and Center-aligned Mode)
46 (++) One-pulse mode output
47
48 ##### How to use this driver #####
49 ==============================================================================
50 [..]
51 (#) Initialize the TIM low level resources by implementing the following functions
52 depending from feature used :
53 (++) Time Base : HAL_TIM_Base_MspInit()
54 (++) Input Capture : HAL_TIM_IC_MspInit()
55 (++) Output Compare : HAL_TIM_OC_MspInit()
56 (++) PWM generation : HAL_TIM_PWM_MspInit()
57 (++) One-pulse mode output : HAL_TIM_OnePulse_MspInit()
58 (++) Encoder mode output : HAL_TIM_Encoder_MspInit()
59
60 (#) Initialize the TIM low level resources :
61 (##) Enable the TIM interface clock using __HAL_RCC_TIMx_CLK_ENABLE();
62 (##) TIM pins configuration
63 (+++) Enable the clock for the TIM GPIOs using the following function:
64 __HAL_RCC_GPIOx_CLK_ENABLE();
65 (+++) Configure these TIM pins in Alternate function mode using HAL_GPIO_Init();
66
67 (#) The external Clock can be configured, if needed (the default clock is the
68 internal clock from the APBx), using the following function:
69 HAL_TIM_ConfigClockSource, the clock configuration should be done before
70 any start function.
71
72 (#) Configure the TIM in the desired functioning mode using one of the
73 Initialization function of this driver:
74 (++) HAL_TIM_Base_Init: to use the Timer to generate a simple time base
75 (++) HAL_TIM_OC_Init and HAL_TIM_OC_ConfigChannel: to use the Timer to generate an
76 Output Compare signal.
77 (++) HAL_TIM_PWM_Init and HAL_TIM_PWM_ConfigChannel: to use the Timer to generate a
78 PWM signal.
79 (++) HAL_TIM_IC_Init and HAL_TIM_IC_ConfigChannel: to use the Timer to measure an
80 external signal.
81 (++) HAL_TIM_OnePulse_Init and HAL_TIM_OnePulse_ConfigChannel: to use the Timer
82 in One Pulse Mode.
83 (++) HAL_TIM_Encoder_Init: to use the Timer Encoder Interface.
84
85 (#) Activate the TIM peripheral using one of the start functions depending from the feature used:
86 (++) Time Base : HAL_TIM_Base_Start(), HAL_TIM_Base_Start_DMA(), HAL_TIM_Base_Start_IT()
87 (++) Input Capture : HAL_TIM_IC_Start(), HAL_TIM_IC_Start_DMA(), HAL_TIM_IC_Start_IT()
88 (++) Output Compare : HAL_TIM_OC_Start(), HAL_TIM_OC_Start_DMA(), HAL_TIM_OC_Start_IT()
89 (++) PWM generation : HAL_TIM_PWM_Start(), HAL_TIM_PWM_Start_DMA(), HAL_TIM_PWM_Start_IT()
90 (++) One-pulse mode output : HAL_TIM_OnePulse_Start(), HAL_TIM_OnePulse_Start_IT()
91 (++) Encoder mode output : HAL_TIM_Encoder_Start(), HAL_TIM_Encoder_Start_DMA(), HAL_TIM_Encoder_Start_IT().
92
93 (#) The DMA Burst is managed with the two following functions:
94 HAL_TIM_DMABurst_WriteStart()
95 HAL_TIM_DMABurst_ReadStart()
