(#) 16-bit programmable prescaler allowing dividing (also on the fly) the counter clock frequency either by any factor between 1 and 65536. (#) Up to 4 independent channels for: (++) Input Capture (++) Output Compare (++) PWM generation (Edge and Center-aligned Mode) (++) One-pulse mode output (#) Synchronization circuit to control the timer with external signals and to interconnect several timers together. (#) Supports incremental encoder for positioning purposes ##### How to use this driver ##### ============================================================================== [..] (#) Initialize the TIM low level resources by implementing the following functions depending on the selected feature: (++) Time Base : HAL_TIM_Base_MspInit() (++) Input Capture : HAL_TIM_IC_MspInit() (++) Output Compare : HAL_TIM_OC_MspInit() (++) PWM generation : HAL_TIM_PWM_MspInit() (++) One-pulse mode output : HAL_TIM_OnePulse_MspInit() (++) Encoder mode output : HAL_TIM_Encoder_MspInit() (#) Initialize the TIM low level resources : (##) Enable the TIM interface clock using __HAL_RCC_TIMx_CLK_ENABLE(); (##) TIM pins configuration (+++) Enable the clock for the TIM GPIOs using the following function: __HAL_RCC_GPIOx_CLK_ENABLE(); (+++) Configure these TIM pins in Alternate function mode using HAL_GPIO_Init(); (#) 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. (#) Configure the TIM in the desired functioning mode using one of the Initialization function of this driver: (++) HAL_TIM_Base_Init: to use the Timer to generate a simple time base (++) HAL_TIM_OC_Init and HAL_TIM_OC_ConfigChannel: to use the Timer to generate an Output Compare signal. (++) HAL_TIM_PWM_Init and HAL_TIM_PWM_ConfigChannel: to use the Timer to generate a PWM signal. (++) HAL_TIM_IC_Init and HAL_TIM_IC_ConfigChannel: to use the Timer to measure an external signal. (++) HAL_TIM_OnePulse_Init and HAL_TIM_OnePulse_ConfigChannel: to use the Timer in One Pulse Mode. (++) HAL_TIM_Encoder_Init: to use the Timer Encoder Interface. (#) Activate the TIM peripheral using one of the start functions depending from the feature used: (++) Time Base : HAL_TIM_Base_Start(), HAL_TIM_Base_Start_DMA(), HAL_TIM_Base_Start_IT() (++) Input Capture : HAL_TIM_IC_Start(), HAL_TIM_IC_Start_DMA(), HAL_TIM_IC_Start_IT() (++) Output Compare : HAL_TIM_OC_Start(), HAL_TIM_OC_Start_DMA(), HAL_TIM_OC_Start_IT() (++) PWM generation : HAL_TIM_PWM_Start(), HAL_TIM_PWM_Start_DMA(), HAL_TIM_PWM_Start_IT() (++) One-pulse mode output : HAL_TIM_OnePulse_Start(), HAL_TIM_OnePulse_Start_IT() (++) Encoder mode output : HAL_TIM_Encoder_Start(), HAL_TIM_Encoder_Start_DMA(), HAL_TIM_Encoder_Start_IT(). (#) The DMA Burst is managed with the two following functions: HAL_TIM_DMABurst_WriteStart() HAL_TIM_DMABurst_ReadStart() *** Callback registration *** ============================================= [..] The compilation define USE_HAL_TIM_REGISTER_CALLBACKS when set to 1 allows the user to configure dynamically the driver callbacks. [..] Use Function HAL_TIM_RegisterCallback() to register a callback. HAL_TIM_RegisterCallback() takes as parameters the HAL peripheral handle, the Callback ID and a pointer to the user callback function. [..] Use function HAL_TIM_UnRegisterCallback() to reset a callback to the default weak function. HAL_TIM_UnRegisterCallback takes as parameters the HAL peripheral handle, and the Callback ID. [..] These functions allow to register/unregister following callbacks: (+) Base_MspInitCallback : TIM Base Msp Init Callback. (+) Base_MspDeInitCallback : TIM Base Msp DeInit Callback. (+) IC_MspInitCallback : TIM IC Msp Init Callback. (+) IC_MspDeInitCallback : TIM IC Msp DeInit Callback. (+) OC_MspInitCallback : TIM OC Msp Init Callback. (+) OC_MspDeInitCallback : TIM OC Msp DeInit Callback. (+) PWM_MspInitCallback : TIM PWM Msp Init Callback. (+) PWM_MspDeInitCallback : TIM PWM Msp DeInit Callback. (+) OnePulse_MspInitCallback : TIM One Pulse Msp Init Callback. (+) OnePulse_MspDeInitCallback : TIM One Pulse Msp DeInit Callback. (+) Encoder_MspInitCallback : TIM Encoder Msp Init Callback. (+) Encoder_MspDeInitCallback : TIM Encoder Msp DeInit Callback. (+) HallSensor_MspInitCallback : TIM Hall Sensor Msp Init Callback. (+) HallSensor_MspDeInitCallback : TIM Hall Sensor Msp DeInit Callback. (+) PeriodElapsedCallback : TIM Period Elapsed Callback. (+) PeriodElapsedHalfCpltCallback : TIM Period Elapsed half complete Callback. (+) TriggerCallback : TIM Trigger Callback. (+) TriggerHalfCpltCallback : TIM Trigger half complete Callback. (+) IC_CaptureCallback : TIM Input Capture Callback. (+) IC_CaptureHalfCpltCallback : TIM Input Capture half complete Callback. (+) OC_DelayElapsedCallback : TIM Output Compare Delay Elapsed Callback. (+) PWM_PulseFinishedCallback : TIM PWM Pulse Finished Callback. (+) PWM_PulseFinishedHalfCpltCallback : TIM PWM Pulse Finished half complete Callback. (+) ErrorCallback : TIM Error Callback. (+) CommutationCallback : TIM Commutation Callback. (+) CommutationHalfCpltCallback : TIM Commutation half complete Callback. (+) BreakCallback : TIM Break Callback. (+) Break2Callback : TIM Break2 Callback. [..] By default, after the Init and when the state is HAL_TIM_STATE_RESET all interrupt callbacks are set to the corresponding weak functions: examples HAL_TIM_TriggerCallback(), HAL_TIM_ErrorCallback(). [..] Exception done for MspInit and MspDeInit functions that are reset to the legacy weak functionalities in the Init / DeInit only when these callbacks are null (not registered beforehand). If not, MspInit or MspDeInit are not null, the Init / DeInit keep and use the user MspInit / MspDeInit callbacks(registered beforehand) [..] Callbacks can be registered / unregistered in HAL_TIM_STATE_READY state only. Exception done MspInit / MspDeInit that can be registered / unregistered in HAL_TIM_STATE_READY or HAL_TIM_STATE_RESET state, thus registered(user) MspInit / DeInit callbacks can be used during the Init / DeInit. In that case first register the MspInit/MspDeInit user callbacks using HAL_TIM_RegisterCallback() before calling DeInit or Init function. [..] When The compilation define USE_HAL_TIM_REGISTER_CALLBACKS is set to 0 or not defined, the callback registration feature is not available and all callbacks are set to the corresponding weak functions. @endverbatim ****************************************************************************** */ /* Includes ------------------------------------------------------------------*/ #include "stm32g0xx_hal.h" /** @addtogroup STM32G0xx_HAL_Driver * @{ */ /** @defgroup TIM TIM * @brief TIM HAL module driver * @{ */ #ifdef HAL_TIM_MODULE_ENABLED /* Private typedef -----------------------------------------------------------*/ /* Private define ------------------------------------------------------------*/ /** @addtogroup TIM_Private_Constants * @{ */ #define TIMx_OR1_OCREF_CLR 0x00000001U /** * @} */ /* Private macros ------------------------------------------------------------*/ /* Private variables ---------------------------------------------------------*/ /* Private function prototypes -----------------------------------------------*/ /** @addtogroup TIM_Private_Functions * @{ */ static void TIM_OC1_SetConfig(TIM_TypeDef *TIMx, const TIM_OC_InitTypeDef *OC_Config); static void TIM_OC3_SetConfig(TIM_TypeDef *TIMx, const TIM_OC_InitTypeDef *OC_Config); static void TIM_OC4_SetConfig(TIM_TypeDef *TIMx, const TIM_OC_InitTypeDef *OC_Config); static void TIM_OC5_SetConfig(TIM_TypeDef *TIMx, const TIM_OC_InitTypeDef *OC_Config); static void TIM_OC6_SetConfig(TIM_TypeDef *TIMx, const TIM_OC_InitTypeDef *OC_Config); static void TIM_TI1_ConfigInputStage(TIM_TypeDef *TIMx, uint32_t TIM_ICPolarity, uint32_t TIM_ICFilter); static void TIM_TI2_SetConfig(TIM_TypeDef *TIMx, uint32_t TIM_ICPolarity, uint32_t TIM_ICSelection, uint32_t TIM_ICFilter); static void TIM_TI2_ConfigInputStage(TIM_TypeDef *TIMx, uint32_t TIM_ICPolarity, uint32_t TIM_ICFilter); static void TIM_TI3_SetConfig(TIM_TypeDef *TIMx, uint32_t TIM_ICPolarity, uint32_t TIM_ICSelection, uint32_t TIM_ICFilter); static void TIM_TI4_SetConfig(TIM_TypeDef *TIMx, uint32_t TIM_ICPolarity, uint32_t TIM_ICSelection, uint32_t TIM_ICFilter); static void TIM_ITRx_SetConfig(TIM_TypeDef *TIMx, uint32_t InputTriggerSource); static void TIM_DMAPeriodElapsedCplt(DMA_HandleTypeDef *hdma); static void TIM_DMAPeriodElapsedHalfCplt(DMA_HandleTypeDef *hdma); static void TIM_DMADelayPulseCplt(DMA_HandleTypeDef *hdma); static void TIM_DMATriggerCplt(DMA_HandleTypeDef *hdma); static void TIM_DMATriggerHalfCplt(DMA_HandleTypeDef *hdma); static HAL_StatusTypeDef TIM_SlaveTimer_SetConfig(TIM_HandleTypeDef *htim, const TIM_SlaveConfigTypeDef *sSlaveConfig); /** * @} */ /* Exported functions --------------------------------------------------------*/ /** @defgroup TIM_Exported_Functions TIM Exported Functions * @{ */ /** @defgroup TIM_Exported_Functions_Group1 TIM Time Base functions * @brief Time Base functions * @verbatim ============================================================================== ##### Time Base functions ##### ============================================================================== [..] This section provides functions allowing to: (+) Initialize and configure the TIM base.
