Constructors
SpiControllerApiWrapper(NativeApi api)
public SpiControllerApiWrapper(NativeApi api)
Wraps the given native API as a provider.
| Parameter | Type | Description |
|---|---|---|
api | NativeApi |
Properties
Api
public NativeApi Api { get; }
The underlying native API descriptor.
ChipSelectLineCount
public extern int ChipSelectLineCount { get; }
Number of hardware chip-select lines exposed by this controller. (inherited)
MinClockFrequency
public extern int MinClockFrequency { get; }
Minimum SCK frequency in Hz. (inherited)
MaxClockFrequency
public extern int MaxClockFrequency { get; }
Maximum SCK frequency in Hz. (inherited)
SupportedDataBitLengths
public extern int[] SupportedDataBitLengths { get; }
Supported frame widths in bits. (inherited)
Methods
Dispose()
public void Dispose()
Releases the native controller.
SetActiveSettings(SpiConnectionSettings connectionSettings)
public extern void SetActiveSettings(SpiConnectionSettings connectionSettings)
Applies a complete set of serial settings (baud, framing, handshake, polarity). (inherited)
| Parameter | Type | Description |
|---|---|---|
connectionSettings | SpiConnectionSettings |
WriteRead(byte[] writeBuffer, int writeOffset, int writeLength, byte[] readBuffer, int readOffset, int readLength, bool deselectAfter)
public extern void WriteRead(byte[] writeBuffer, int writeOffset, int writeLength, byte[] readBuffer, int readOffset, int readLength, bool deselectAfter)
Performs a full-duplex transfer. (inherited)
| 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). |
