void Soft_SPI_Init();
Returns Nothing.
Description Configures and initializes the software SPI module.
Requires
Global variables:
- Chip_Select: Chip_Select line
- SoftSpi_SDI: Data in line
- SoftSpi_SDO: Data out line
- SoftSpi_CLK: Data clock line
- Chip_Select_Direction: Direction of the Chip_Select_Direction pin
-
SoftSpi_SDI_Direction: Direction of the Data in pin
-
SoftSpi_SDO_Direction: Direction of the Data out pin
