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.
