****************************************************************************** + @verbatim + ============================================================================== + ##### How to use this driver ##### + ============================================================================== + [..] + The DSI HAL driver can be used as follows: + + (#) Declare a DSI_HandleTypeDef handle structure, for example: DSI_HandleTypeDef hdsi; + + (#) Initialize the DSI low level resources by implementing the HAL_DSI_MspInit() API: + (##) Enable the DSI interface clock + (##) NVIC configuration if you need to use interrupt process + (+++) Configure the DSI interrupt priority + (+++) Enable the NVIC DSI IRQ Channel + + (#) Initialize the DSI Host peripheral, the required PLL parameters, number of lances and + TX Escape clock divider by calling the HAL_DSI_Init() API which calls HAL_DSI_MspInit(). + + *** Configuration *** + ========================= + [..] + (#) Use HAL_DSI_ConfigAdaptedCommandMode() function to configure the DSI host in adapted + command mode. + + (#) When operating in video mode , use HAL_DSI_ConfigVideoMode() to configure the DSI host. + + (#) Function HAL_DSI_ConfigCommand() is used to configure the DSI commands behavior in low power mode. + + (#) To configure the DSI PHY timings parameters, use function HAL_DSI_ConfigPhyTimer(). + + (#) The DSI Host can be started/stopped using respectively functions HAL_DSI_Start() and HAL_DSI_Stop(). + Functions HAL_DSI_ShortWrite(), HAL_DSI_LongWrite() and HAL_DSI_Read() allows respectively + to write DSI short packets, long packets and to read DSI packets. + + (#) The DSI Host Offers two Low power modes : + (++) Low Power Mode on data lanes only: Only DSI data lanes are shut down. + It is possible to enter/exit from this mode using respectively functions HAL_DSI_EnterULPMData() + and HAL_DSI_ExitULPMData() + + (++) Low Power Mode on data and clock lanes : All DSI lanes are shut down including data and clock lanes. + It is possible to enter/exit from this mode using respectively functions HAL_DSI_EnterULPM() + and HAL_DSI_ExitULPM() + + (#) To control DSI state you can use the following function: HAL_DSI_GetState() + + *** Error management *** + ======================== + [..] + (#) User can select the DSI errors to be reported/monitored using function HAL_DSI_ConfigErrorMonitor() + When an error occurs, the callback HAL_DSI_ErrorCallback() is asserted and then user can retrieve + the error code by calling function HAL_DSI_GetError() + + *** DSI HAL driver macros list *** + ============================================= + [..] + Below the list of most used macros in DSI HAL driver. + + (+) __HAL_DSI_ENABLE: Enable the DSI Host. + (+) __HAL_DSI_DISABLE: Disable the DSI Host. + (+) __HAL_DSI_WRAPPER_ENABLE: Enables the DSI wrapper. + (+) __HAL_DSI_WRAPPER_DISABLE: Disable the DSI wrapper. + (+) __HAL_DSI_PLL_ENABLE: Enables the DSI PLL. + (+) __HAL_DSI_PLL_DISABLE: Disables the DSI PLL. + (+) __HAL_DSI_REG_ENABLE: Enables the DSI regulator. + (+) __HAL_DSI_REG_DISABLE: Disables the DSI regulator. + (+) __HAL_DSI_GET_FLAG: Get the DSI pending flags. + (+) __HAL_DSI_CLEAR_FLAG: Clears the DSI pending flags. + (+) __HAL_DSI_ENABLE_IT: Enables the specified DSI interrupts. + (+) __HAL_DSI_DISABLE_IT: Disables the specified DSI interrupts. + (+) __HAL_DSI_GET_IT_SOURCE: Checks whether the specified DSI interrupt source is enabled or not. + + [..] + (@) You can refer to the DSI HAL driver header file for more useful macros + + *** Callback registration *** + ============================================= + [..] + The compilation define USE_HAL_DSI_REGISTER_CALLBACKS when set to 1 + allows the user to configure dynamically the driver callbacks. + Use Function HAL_DSI_RegisterCallback() to register a callback. + + [..] + Function HAL_DSI_RegisterCallback() allows to register following callbacks: + (+) TearingEffectCallback : DSI Tearing Effect Callback. + (+) EndOfRefreshCallback : DSI End Of Refresh Callback. + (+) ErrorCallback : DSI Error Callback + (+) MspInitCallback : DSI MspInit. + (+) MspDeInitCallback : DSI MspDeInit. + [..] + This function takes as parameters the HAL peripheral handle, the callback ID + and a pointer to the user callback function. + + [..] + Use function HAL_DSI_UnRegisterCallback() to reset a callback to the default + weak function. + HAL_DSI_UnRegisterCallback takes as parameters the HAL peripheral handle, + and the callback ID. + [..] + This function allows to reset following callbacks: + (+) TearingEffectCallback : DSI Tearing Effect Callback. + (+) EndOfRefreshCallback : DSI End Of Refresh Callback. + (+) ErrorCallback : DSI Error Callback + (+) MspInitCallback : DSI MspInit. + (+) MspDeInitCallback : DSI MspDeInit. + + [..] + By default, after the HAL_DSI_Init and when the state is HAL_DSI_STATE_RESET + all callbacks are set to the corresponding weak functions: + examples HAL_DSI_TearingEffectCallback(), HAL_DSI_EndOfRefreshCallback(). + Exception done for MspInit and MspDeInit functions that are respectively + reset to the legacy weak (surcharged) functions in the HAL_DSI_Init() + and HAL_DSI_DeInit() only when these callbacks are null (not registered beforehand). + If not, MspInit or MspDeInit are not null, the HAL_DSI_Init() and HAL_DSI_DeInit() + keep and use the user MspInit/MspDeInit callbacks (registered beforehand). + + [..] + Callbacks can be registered/unregistered in HAL_DSI_STATE_READY state only. + Exception done MspInit/MspDeInit that can be registered/unregistered + in HAL_DSI_STATE_READY or HAL_DSI_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_DSI_RegisterCallback() before calling HAL_DSI_DeInit() + or HAL_DSI_Init() function. + + [..] + When The compilation define USE_HAL_DSI_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. + +
