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,

) |
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
