@CHIP-RTOS C Library - SPI API

Header File:         #include <SPIAPI.H>

SPI is a serial bus standard established by Motorola. The Serial Peripheral Interface (SPI) is a synchronous serial interface useful for communicating with other peripheral or microcontroller devices. These peripheral devices may be Serial EEPROMs, shift registers, display drivers, A/D converters, etc.

SPI Init Functions

spi_init	Init the SPI Interface (software emulation)

SPI Access Functions

spi_write	Write to the SPI Interface (software emulation/hardware interface)
spi_read	Read from the SPI Interface (software emulation/hardware interface)
spi_read_write	Read and write from/to the SPI Interface (software emulation/hardware interface)
spi_write_hw	Write to the SPI Interface (with return value for hardware interface)
spi_read_hw	Read from the SPI Interface (with return value for hardware interface)
spi_read_write_hw	Read and write from/to the SPI Interface (with return value for hardware interface)
spi_waiton_sem	Wait on SPI semaphore (hardware interface)
spi_waiton_sem_setmode	Wait on SPI semaphore, set SPI mode and divider (hardware interface)
