I have some BBG devices, and a selection of grove sensors and LEDs.
My BBG is running Ubuntu 14.04.3 LTS, the BBG flasher version from Robert Nelson as described on elinux.
Now I’m trying to figure out how to detect and access any of the grove sensors. I’d like to do this from C++. Where do I need to start looking?
I found the onboard LEDs at /sys/devices/platform/leds/leds/beaglebone:green:usrX/ and can turn them on and off at will, which was a nice start.
But where do I find documentation on how to access “grove” sensors?
