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. |
