Data Structure Documentation

◆ GFXMMU_BuffersTypeDef

struct GFXMMU_BuffersTypeDef

GFXMMU buffers structure definition.

Definition at line 58 of file stm32l4xx_hal_gfxmmu.h.

Data Fields
uint32_t	Buf0Address	Physical address of buffer 0.
uint32_t	Buf1Address	Physical address of buffer 1.
uint32_t	Buf2Address	Physical address of buffer 2.
uint32_t	Buf3Address	Physical address of buffer 3.

◆ GFXMMU_InterruptsTypeDef

struct GFXMMU_InterruptsTypeDef

GFXMMU interrupts structure definition.

Definition at line 69 of file stm32l4xx_hal_gfxmmu.h.

Data Fields

FunctionalState

Activation

Interrupts enable/disable

uint32_t

UsedInterrupts

Interrupts used. This parameter can be a values combination of GFXMMU interrupts.

Note: : Usefull only when interrupts are enabled.

◆ GFXMMU_InitTypeDef

struct GFXMMU_InitTypeDef

GFXMMU init structure definition.

Definition at line 80 of file stm32l4xx_hal_gfxmmu.h.

Data Fields
uint32_t	BlocksPerLine	Number of blocks of 16 bytes per line. This parameter can be a value of GFXMMU blocks per line.
GFXMMU_BuffersTypeDef	Buffers	Physical buffers addresses.
uint32_t	DefaultValue	Value returned when virtual memory location not physically mapped.
GFXMMU_InterruptsTypeDef	Interrupts	Interrupts parameters.

◆ GFXMMU_LutLineTypeDef

struct GFXMMU_LutLineTypeDef

GFXMMU LUT line structure definition.

Definition at line 112 of file stm32l4xx_hal_gfxmmu.h.

Data Fields
uint32_t	FirstVisibleBlock	First visible block on this line. This parameter must be a number between Min_Data = 0 and Max_Data = 255.
uint32_t	LastVisibleBlock	Last visible block on this line. This parameter must be a number between Min_Data = 0 and Max_Data = 255.
uint32_t	LineNumber	LUT line number. This parameter must be a number between Min_Data = 0 and Max_Data = 1023.
int32_t	LineOffset	Offset of block 0 of the current line in physical buffer. This parameter must be a number between Min_Data = -4080 and Max_Data = 4190208. Note : Line offset has to be computed with the following formula: LineOffset = [(Blocks already used) - (1st visible block)]*BlockSize.
uint32_t	LineStatus	LUT line enable/disable. This parameter can be a value of GFXMMU LUT line status.
