U2C_RESULT U2C_SpiGetConfig(
HANDLE hDevice,
BYTE* pCPOL,
BYTE* pCPHA
);
The U2C_SpiGetConfig() function obtains SPI bus configuration (clock polarity and phase).
Parameters:
- hDevice
Handle to the U2C-12 device.
- pCPOL
A pointer to the byte to be filled with current SPI bus clock polarity setting. Clock polarity determines the CLK line idle state, where:
- 0 corresponds to "idle low"
- 1 corresponds to "idle high"
- pCPHA
A pointer to byte to be filled with current SPI bus clock phase setting. 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 configuration was successfully obtained.
U2C_HARDWARE_NOT_FOUND
U2C-12 device referenced by hDevice handle was not found.
