Xenomai real-time driver to control shift registers on Elk Pi boards using GPIOs and SPI.
Xenomai real-time driver to control shift registers on Elk Pi boards using GPIOs and SPI.
Based on Nicolas Schurando’s spi-bcm283x-rtdm driver:
https://github.com/nicolas-schurando/spi-bcm283x-rtdm.git.

Navigate to boards/\<board-name>
and then build with:
$ export KERNEL_PATH=<path to kernel source>$ export CROSS_COMPILE=<arm compiler prefix>$ make
To load the driver :insmod shiftreg_rtdm.ko adc_chans_per_tick=4
where adc_chans_per_tick specifies how many adc channels are sampled per iteration.
