Function Documentation

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

Parameters
[in] tftInit Pointer to EBI TFT initialization structure
Returns
true if we should redraw into buffer, false if BC has control over display
