Added SPI burst mode to this graphics driver. If whoever wants this rolled in to repository let me know. I replaced _spi.write(); with fastWrite(); and clearRX();
SPI8.cpp
// need to re-create SPI firmware to access SPI handle
static SPI_HandleTypeDef SpiHandle;
void SPI8::fastWrite(int data) {
SpiHandle.Instance = SPI1;
// Check if data is transmitted
while ((SpiHandle.Instance->SR & SPI_SR_TXE) == 0);
SpiHandle.Instance->DR = data;
}
void SPI8::clearRX( void ) {
SpiHandle.Instance = SPI1;
//Check if the RX buffer is busy
//While busy, keep checking
while (SpiHandle.Instance->SR & SPI_SR_BSY){
// Check RX buffer readable
while ((SpiHandle.Instance->SR & SPI_SR_RXNE) == 0);
int dummy = SpiHandle.Instance->DR;
}
}

If char is not in font, print blank.; Useful if you have a number only font and want to format output.

The width and height of SEPS225 are 0x80, but I mistook it to 0x7F in the first version and have fixed them in later version, but in the newest version we had the return of 0x7F, so I try to fix them to 0x80 again.
