Detailed Description

LCC driver functions and definitions.

This header file contains the function prototypes and definitions of the data types and constants that make up the interface to the Low-Cost Controllerless (LCC) Graphics Controller.

This driver is configured via MHC and generated specific to the configuration and hardware architecture set in MHC.

Function Documentation

◆ DRV_LCC_BlitBuffer()

gfxResult DRV_LCC_BlitBuffer	(	int32_t	x,
		int32_t	y,
		gfxPixelBuffer *	buf
	)

Blit buffer.

Copies buf to the framebuffer at location x and y.

gfxDisplayDriver* drv;

gfxResult res = drv->blitBuffer();

Returns: GFX_SUCCESS if blit was performed, otherwise GFX_FAILURE.

◆ DRV_LCC_Initialize()

gfxResult DRV_LCC_Initialize ( void )

Initialize driver.

Initializes the LCC driver. This routine is typically called by a graphics library or by the application during application initialization.

gfxResult res = DRV_LCC_Initialize();

Returns: GFX_SUCCESS if driver ready to render, otherwise GFX_FAILURE.

Here is the call graph for this function:

◆ DRV_LCC_IOCTL()

gfxDriverIOCTLResponse DRV_LCC_IOCTL	(	gfxDriverIOCTLRequest	req,
		void *	arg
	)

Graphics driver generic IOCTL interface.

Sends an IOCTL message to the driver.

gfxIOCTLArg_Value val;
val.value.v_uint = 1;
DRV_LCC_IOCTL(GFX_IOCTL_FRAME_START, &val);

Returns: gfxDriverIOCTLResponse the IOCTL handler response

◆ DRV_LCC_Update()

void DRV_LCC_Update ( void )

Execute update task.

Performs a driver task update.

DRV_LCC_Update();

Returns: void.
