Methods

SetActiveSettings(SpiConnectionSettings connectionSettings)

void SetActiveSettings(SpiConnectionSettings connectionSettings)

Applies the given settings before the next transfer.

Parameter	Type	Description
connectionSettings	SpiConnectionSettings	Per-device configuration.

Write(byte[] writeBuffer, int xOffset, int yOffset, int width, int height, int originalWidth, int columnMultiplier, int rowMultiplier)

void Write(byte[] writeBuffer, int xOffset, int yOffset, int width, int height, int originalWidth, int columnMultiplier, int rowMultiplier)

Writes a rectangular framebuffer region with optional pixel replication.

Parameter	Type	Description
writeBuffer	byte[]
xOffset	int
yOffset	int
width	int
height	int
originalWidth	int
columnMultiplier	int
rowMultiplier	int

WriteRead(byte[] writeBuffer, int writeOffset, int writeLength, byte[] readBuffer, int readOffset, int readLength, bool deselectAfter)

void WriteRead(byte[] writeBuffer, int writeOffset, int writeLength, byte[] readBuffer, int readOffset, int readLength, bool deselectAfter)

Performs a full-duplex transfer.

Parameter	Type	Description
writeBuffer	byte[]	Bytes to transmit, or null for read-only.
writeOffset	int	Starting offset within writeBuffer.
writeLength	int	Number of bytes to transmit.
readBuffer	byte[]	Destination buffer for received bytes, or null to discard.
readOffset	int	Starting offset within readBuffer.
readLength	int	Number of bytes to receive.
deselectAfter	bool	If false, leaves chip-select asserted after the transfer (for sequential read-after-write).
