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; } }
