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.
