45 ##### TIMER Generic features #####
46 ==============================================================================
47 [..] The Timer features include:
48 (#) 16-bit up, down, up/down auto-reload counter.
49 (#) 16-bit programmable prescaler allowing dividing (also on the fly) the
50 counter clock frequency either by any factor between 1 and 65536.
51 (#) Up to 4 independent channels for:
52 (++) Input Capture
53 (++) Output Compare
54 (++) PWM generation (Edge and Center-aligned Mode)
55 (++) One-pulse mode output
56 (#) Synchronization circuit to control the timer with external signals and to interconnect
57 several timers together.
58 (#) Supports incremental encoder for positioning purposes
59
60 ##### How to use this driver #####
61 ==============================================================================
62 [..]
63 (#) Initialize the TIM low level resources by implementing the following functions
64 depending on the selected feature:
65 (++) Time Base : HAL_TIM_Base_MspInit()
66 (++) Input Capture : HAL_TIM_IC_MspInit()
67 (++) Output Compare : HAL_TIM_OC_MspInit()
68 (++) PWM generation : HAL_TIM_PWM_MspInit()
69 (++) One-pulse mode output : HAL_TIM_OnePulse_MspInit()
70 (++) Encoder mode output : HAL_TIM_Encoder_MspInit()
71
72 (#) Initialize the TIM low level resources :
73 (##) Enable the TIM interface clock using __HAL_RCC_TIMx_CLK_ENABLE();
74 (##) TIM pins configuration
75 (+++) Enable the clock for the TIM GPIOs using the following function:
76 __HAL_RCC_GPIOx_CLK_ENABLE();
77 (+++) Configure these TIM pins in Alternate function mode using HAL_GPIO_Init();
78
79 (#) The external Clock can be configured, if needed (the default clock is the
80 internal clock from the APBx), using the following function:
81 HAL_TIM_ConfigClockSource, the clock configuration should be done before
82 any start function.
83
84 (#) Configure the TIM in the desired functioning mode using one of the
85 Initialization function of this driver:
86 (++) HAL_TIM_Base_Init: to use the Timer to generate a simple time base
87 (++) HAL_TIM_OC_Init and HAL_TIM_OC_ConfigChannel: to use the Timer to generate an
88 Output Compare signal.
89 (++) HAL_TIM_PWM_Init and HAL_TIM_PWM_ConfigChannel: to use the Timer to generate a
90 PWM signal.
91 (++) HAL_TIM_IC_Init and HAL_TIM_IC_ConfigChannel: to use the Timer to measure an
92 external signal.
93 (++) HAL_TIM_OnePulse_Init and HAL_TIM_OnePulse_ConfigChannel: to use the Timer
94 in One Pulse Mode.
95 (++) HAL_TIM_Encoder_Init: to use the Timer Encoder Interface.
96
97 (#) Activate the TIM peripheral using one of the start functions depending from the feature used:
98 (++) Time Base : HAL_TIM_Base_Start(), HAL_TIM_Base_Start_DMA(), HAL_TIM_Base_Start_IT()
99 (++) Input Capture : HAL_TIM_IC_Start(), HAL_TIM_IC_Start_DMA(), HAL_TIM_IC_Start_IT()
100 (++) Output Compare : HAL_TIM_OC_Start(), HAL_TIM_OC_Start_DMA(), HAL_TIM_OC_Start_IT()
101 (++) PWM generation : HAL_TIM_PWM_Start(), HAL_TIM_PWM_Start_DMA(), HAL_TIM_PWM_Start_IT()
102 (++) One-pulse mode output : HAL_TIM_OnePulse_Start(), HAL_TIM_OnePulse_Start_IT()
103 (++) Encoder mode output : HAL_TIM_Encoder_Start(), HAL_TIM_Encoder_Start_DMA(), HAL_TIM_Encoder_Start_IT().
104
105 (#) The DMA Burst is managed with the two following functions:
106 HAL_TIM_DMABurst_WriteStart()
107 HAL_TIM_DMABurst_ReadStart()
108
109 *** Callback registration ***
110 =============================================
111
112 [..]
113 The compilation define USE_HAL_TIM_REGISTER_CALLBACKS when set to 1
114 allows the user to configure dynamically the driver callbacks.
115
116 [..]
117 Use Function HAL_TIM_RegisterCallback() to register a callback.
118 HAL_TIM_RegisterCallback() takes as parameters the HAL peripheral handle,
119 the Callback ID and a pointer to the user callback function.
120
121 [..]
122 Use function HAL_TIM_UnRegisterCallback() to reset a callback to the default
123 weak function.
124 HAL_TIM_UnRegisterCallback takes as parameters the HAL peripheral handle,
125 and the Callback ID.
126
127 [..]
128 These functions allow to register/unregister following callbacks:
129 (+) Base_MspInitCallback : TIM Base Msp Init Callback.
130 (+) Base_MspDeInitCallback : TIM Base Msp DeInit Callback.
131 (+) IC_MspInitCallback : TIM IC Msp Init Callback.
132 (+) IC_MspDeInitCallback : TIM IC Msp DeInit Callback.
133 (+) OC_MspInitCallback : TIM OC Msp Init Callback.
134 (+) OC_MspDeInitCallback : TIM OC Msp DeInit Callback.
135 (+) PWM_MspInitCallback : TIM PWM Msp Init Callback.
136 (+) PWM_MspDeInitCallback : TIM PWM Msp DeInit Callback.
137 (+) OnePulse_MspInitCallback : TIM One Pulse Msp Init Callback.
138 (+) OnePulse_MspDeInitCallback : TIM One Pulse Msp DeInit Callback.
139 (+) Encoder_MspInitCallback : TIM Encoder Msp Init Callback.
140 (+) Encoder_MspDeInitCallback : TIM Encoder Msp DeInit Callback.
141 (+) HallSensor_MspInitCallback : TIM Hall Sensor Msp Init Callback.
142 (+) HallSensor_MspDeInitCallback : TIM Hall Sensor Msp DeInit Callback.
143 (+) PeriodElapsedCallback : TIM Period Elapsed Callback.
144 (+) PeriodElapsedHalfCpltCallback : TIM Period Elapsed half complete Callback.
145 (+) TriggerCallback : TIM Trigger Callback.
146 (+) TriggerHalfCpltCallback : TIM Trigger half complete Callback.
147 (+) IC_CaptureCallback : TIM Input Capture Callback.
148 (+) IC_CaptureHalfCpltCallback : TIM Input Capture half complete Callback.
149 (+) OC_DelayElapsedCallback : TIM Output Compare Delay Elapsed Callback.
150 (+) PWM_PulseFinishedCallback : TIM PWM Pulse Finished Callback.
151 (+) PWM_PulseFinishedHalfCpltCallback : TIM PWM Pulse Finished half complete Callback.
152 (+) ErrorCallback : TIM Error Callback.
153 (+) CommutationCallback : TIM Commutation Callback.
154 (+) CommutationHalfCpltCallback : TIM Commutation half complete Callback.
155 (+) BreakCallback : TIM Break Callback.
156 (+) Break2Callback : TIM Break2 Callback.
157
158 [..]
159 By default, after the Init and when the state is HAL_TIM_STATE_RESET
160 all interrupt callbacks are set to the corresponding weak functions:
161 examples HAL_TIM_TriggerCallback(), HAL_TIM_ErrorCallback().
162
163 [..]
164 Exception done for MspInit and MspDeInit functions that are reset to the legacy weak
165 functionalities in the Init / DeInit only when these callbacks are null
166 (not registered beforehand). If not, MspInit or MspDeInit are not null, the Init / DeInit
167 keep and use the user MspInit / MspDeInit callbacks(registered beforehand)
168
169 [..]
170 Callbacks can be registered / unregistered in HAL_TIM_STATE_READY state only.
171 Exception done MspInit / MspDeInit that can be registered / unregistered
172 in HAL_TIM_STATE_READY or HAL_TIM_STATE_RESET state,
173 thus registered(user) MspInit / DeInit callbacks can be used during the Init / DeInit.
174 In that case first register the MspInit/MspDeInit user callbacks
175 using HAL_TIM_RegisterCallback() before calling DeInit or Init function.
176
177 [..]
178 When The compilation define USE_HAL_TIM_REGISTER_CALLBACKS is set to 0 or
179 not defined, the callback registration feature is not available and all callbacks
180 are set to the corresponding weak functions.
