void SPI_TFT_Init

(

void

)

SPI_TFT_Init Initialize SPI interface to TFT-LCD SSD2119 controller.

Note

To enable access, be sure to call the functions BSP_PeripheralAccess(BSP_TFT, enable); before using this interface.

void SPI_TFT_WriteRegister	(	uint8_t	reg,
		uint16_t	data
	)

SPI_TFT_Write Write registers/data to SSD2119 controller.

Parameters

reg	Register to write to
data	16-bit data to write into register

Note

It's not possible to read back register value through SSD2119 SPI interface, so no SPI_TFT_ReadRegister function is implemented

bool TFT_AddressMappedInit

(

void

)

TFT initialize or reinitialize to Address Mapped Mode Assumes EBI has been configured correctly in BSP_Init(BSP_INIT_DK_EBI)

Returns

true if we should redraw into buffer, false if BC has control over display

bool TFT_DirectInit

(

const EBI_TFTInit_TypeDef *

tftInit

)

TFT initialize or reinitialize Assumes EBI has been configured correctly in BSP_Init(BSP_INIT_DK_EBI)

Parameters

[in]

tftInit

Pointer to EBI TFT initialization structure

Returns

true if we should redraw into buffer, false if BC has control over display
