- ==============================================================================
- ##### How to use this driver #####
- ==============================================================================
- [..]
- *** Initialization ***
- ======================
- [..]
- (#) As prerequisite, fill in the HAL_GFXMMU_MspInit() :
- (++) Enable GFXMMU clock interface with __HAL_RCC_GFXMMU_CLK_ENABLE().
- (++) If interrupts are used, enable and configure GFXMMU global
- interrupt with HAL_NVIC_SetPriority() and HAL_NVIC_EnableIRQ().
- (#) Configure the number of blocks per line, default value, physical
- buffer addresses, cache and pre-fetch parameters and interrupts
- using the HAL_GFXMMU_Init() function.
-
- *** LUT configuration ***
- =========================
- [..]
- (#) Use HAL_GFXMMU_DisableLutLines() to deactivate all LUT lines (or a
- range of lines).
- (#) Use HAL_GFXMMU_ConfigLut() to copy LUT from flash to look up RAM.
- (#) Use HAL_GFXMMU_ConfigLutLine() to configure one line of LUT.
-
- *** Force flush and/or invalidate of cache ***
- ==============================================
- [..]
- (#) Use HAL_GFXMMU_ConfigForceCache() to flush and/or invalidate cache.
-
- *** Modify physical buffer adresses ***
- =======================================
- [..]
- (#) Use HAL_GFXMMU_ModifyBuffers() to modify physical buffer addresses.
-
- *** Modify cache and pre-fetch parameters ***
- =============================================
- [..]
- (#) Use HAL_GFXMMU_ModifyCachePrefetch() to modify cache and pre-fetch
- parameters.
-
- *** Error management ***
- ========================
- [..]
- (#) If interrupts are used, HAL_GFXMMU_IRQHandler() will be called when
- an error occurs. This function will call HAL_GFXMMU_ErrorCallback().
- Use HAL_GFXMMU_GetError() to get the error code.
-
- *** De-initialization ***
- =========================
- [..]
- (#) As prerequisite, fill in the HAL_GFXMMU_MspDeInit() :
- (++) Disable GFXMMU clock interface with __HAL_RCC_GFXMMU_CLK_ENABLE().
- (++) If interrupts has been used, disable GFXMMU global interrupt with
- HAL_NVIC_DisableIRQ().
- (#) De-initialize GFXMMU using the HAL_GFXMMU_DeInit() function.
-
- *** Callback registration ***
- =============================
-
- [..]
- The compilation define USE_HAL_GFXMMU_REGISTER_CALLBACKS when set to 1
- allows the user to configure dynamically the driver callbacks.
- Use functions HAL_GFXMMU_RegisterCallback() to register a user callback.
-
- [..]
- Function HAL_GFXMMU_RegisterCallback() allows to register following callbacks:
- (+) ErrorCallback : GFXMMU error.
- (+) MspInitCallback : GFXMMU MspInit.
- (+) MspDeInitCallback : GFXMMU MspDeInit.
- [..]
- This function takes as parameters the HAL peripheral handle, the callback ID
- and a pointer to the user callback function.
-
- [..]
- Use function HAL_GFXMMU_UnRegisterCallback() to reset a callback to the default
- weak (surcharged) function.
- HAL_GFXMMU_UnRegisterCallback() takes as parameters the HAL peripheral handle,
- and the callback ID.
- [..]
- This function allows to reset following callbacks:
- (+) ErrorCallback : GFXMMU error.
- (+) MspInitCallback : GFXMMU MspInit.
- (+) MspDeInitCallback : GFXMMU MspDeInit.
-
- [..]
- By default, after the HAL_GFXMMU_Init and if the state is HAL_GFXMMU_STATE_RESET
- all callbacks are reset to the corresponding legacy weak (surcharged) functions:
- examples HAL_GFXMMU_ErrorCallback().
- Exception done for MspInit and MspDeInit callbacks that are respectively
- reset to the legacy weak (surcharged) functions in the HAL_GFXMMU_Init
- and HAL_GFXMMU_DeInit only when these callbacks are null (not registered beforehand).
- If not, MspInit or MspDeInit are not null, the HAL_GFXMMU_Init and HAL_GFXMMU_DeInit
- keep and use the user MspInit/MspDeInit callbacks (registered beforehand).
-
- [..]
- Callbacks can be registered/unregistered in READY state only.
- Exception done for MspInit/MspDeInit callbacks that can be registered/unregistered
- in READY or 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_GFXMMU_RegisterCallback before calling HAL_GFXMMU_DeInit
- or HAL_GFXMMU_Init function.
-
- [..]
- When the compilation define USE_HAL_GFXMMU_REGISTER_CALLBACKS is set to 0 or
- not defined, the callback registering feature is not available
- and weak (surcharged) callbacks are used.
