U2C_RESULT U2C_SpiSetConfig (
HANDLE hDevice,
BYTE CPOL,
BYTE CPHA
);
The U2C_SpiSetConfig function configures SPI bus clock polarity and phase.
- Parameters:
-
| hDevice | Handle to the U2C-12 device. |
| CPOL | Clock polarity value determines the CLK line idle state, where:
- 0 corresponds to "idle low"
- 1 corresponds to "idle high"
|
| CPHA | Clock phase value determines the clock edge when the data is valid on the bus, where:
- 0 corresponds to valid data available on leading edge
- 1 corresponds to valid data available on trailing edge
|
- Return values:
-
| U2C_SUCCESS | The SPI bus was successfully configured. |
| U2C_HARDWARE_NOT_FOUND | U2C-12 device referenced by hDevice handle was not found. |
