Functions

void * BSP_getTftSRAMDirectDriveBaseAddress (void)
Get the TFT SRAM base address.
void BSP_initEbiFlash (void)
Initialize the flash.
void BSP_initEbiSram (void)
Initialize the SRAM.
void BSP_initEbiTftDirectDrive (void)
Initialize the TFT display.
void BSP_setTftSRAMDirectDriveBaseAddress (void *baseAddressIn)
Set the TFT SRAM base address. The TFT address is updated according to the EBI_TFTCTRL_FBCTRIG bit. Default is every VSYNC.
static void initEbiCommon (void)
Initialize common EBI settings (GPIO, power and pin routing)
static void initGpio (void)
Initialize GPIO according to bsp_config.h.
