Functions

int Spi_Configure (int channel, int bits, int clockDivider, int delayBeforeSPCK, int delayBetweenTransfers)
 Configure the SPI channel.
int Spi_ReadWriteBlock (int channel, unsigned char *buffer, int count)
 Read/Write a block of data via SPI.

Detailed Description

The SPI subsystem allows the MAKE Controller to communicate with peripheral devices via SPI.

See EEPROM module for an example use.


Function Documentation

int Spi_Configure ( int  channel,
int  bits,
int  clockDivider,
int  delayBeforeSPCK,
int  delayBetweenTransfers 
)

Configure the SPI channel.

This function locks the I/O lines associated with the SPI channel so they cannot be used by another device on the same lines.

Parameters:
channel An integer specifying the SPI channel to configure.
bits An integer specifying the number of bits to transfer (8-16).
clockDivider An integer specifying the desired divider from the serial clock (0 - 255).
delayBeforeSPCK An integer specifying the delay, in ms, before the clock starts (0 - 255).
delayBetweenTransfers An integer specifying how long, in ms, to wait between transfers (0 - 255).
Returns:
0 on success.

int Spi_ReadWriteBlock ( int  channel,
unsigned char *  buffer,
int  count 
)

Read/Write a block of data via SPI.

Parameters:
channel An integer specifying the device to communicate with.
buffer A pointer to the buffer to read to, or write from.
count An integer specifying the length in bytes of the buffer to read/write.
Returns:
0 on success.
