Hello, I have been attempting to write C code for using SPI with the BBB. I am manipulating spidev (in my case spidev1.0) with ioctl() however I am unable to get SPI working. All of the libraries I have tried to use with a similar method also don't seem to work (e.g. https://github.com/deeplyembeddedWP/BeagleBone-SPI-Library, https://github.com/photomankc/BeagleBone-Black-Robot-Library/blob/master/motors/l6470.h). When I hook up the BBB SPI1 pins to the scope, there is no output.
I have disabled the HDMI boot overlays (audio and video) and enabled the SPI1 overlay. I am able to see signals on the scope with the Python Adafruit_BBIO.SPI library but with this method I have been unsuccessful. Is there something else to setup? uname -r: 4.14.71-ti-r80 Thanks! -- For more options, visit http://beagleboard.org/discuss --- You received this message because you are subscribed to the Google Groups "BeagleBoard" group.
