== SPI == | |||
=== Configuring interface === | |||
SPI currently only works in linux. | |||
instrhwinfo will display the avilable devices in the system | |||
{{Code|SPI example|<syntaxhighlight lang="octave" style="font-size:13px"> | |||
instrhwinfo("spi") | |||
</syntaxhighlight> | |||
}} | |||
You will need read/write permissions to the device used. | |||
=== Example: basic use === | |||
Example opening an performing IO on a device /dev/spidev0.0. | |||
{{Code|SPI example|<syntaxhighlight lang="octave" style="font-size:13px"> | |||
# open device | |||
spidev = spi("/dev/spidev0.0", 'clockpolarity', 'idlehigh', 'clockphase', 'firstedge') | |||
# I/O to device | |||
data = writeAndRead (spidev, uint8([0x01 0x00])) | |||
# close the device | |||
clear spidev | |||
