So the ADC is pretty straight forward, for example the proxy cape uses 3 adc channels.. https://github.com/RobertCNelson/dtb-rebuilder/blob/3.14-ti/src/arm/am335x-bone-basic-proto-cape.dtsi So if you add that node (with the 2 adc channels you need) to: https://github.com/RobertCNelson/dtb-rebuilder/blob/3.14-ti/src/arm/am335x-boneblack.dts then it's just make sudo make install sudo reboot (this is with the 3.14-ti branch of dtb-rebuilder) The best gpio example is in the argus dtsi https://github.com/RobertCNelson/dtb-rebuilder/blob/3.14-ti/src/arm/am335x-bone-argus.dtsi Regards, -- Robert Nelson http://www.rcn-ee.com/ -- For more options, visit http://beagleboard.org/discuss --- You received this message because you are subscribed to the Google Groups "BeagleBoard" group.
