##### 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 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.
|
|
|
|
*** Modify physical buffer addresses ***
|
|
=======================================
|
|
[..]
|
|
(#) Use HAL_GFXMMU_ModifyBuffers() to modify physical buffer addresses.
|
|
|
|
*** 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.
