Hi everyone, I'm working on a school project and am in way over my head. I need to control a lego NXT robotic arm using C code running on the BBB. I have the electronics part all sorted out - my groupmate is a wiz with that. The software is giving me trouble though - I'm used to using an old HCS12 board in the school labs, and the BBB is quite different...
I can export and read from the GPIO pins using the method shown here: https://learnbuildshare.wordpress.com/2013/05/29/beaglebone-black-digital-ouput/ . The file opening and closing for every read/write seems really clunky though when I'm trying to read quadrature encoder values... Would it actually work? Or do I need a better method? I think I read somewhere that the ports are memory-mapped and can be accessed that way - is that a different method? Can someone explain how I would do that in C? Also, I need to set the pin mux setting in C as part of this program - can anyone point me in the right direction to do that? :) Thanks for reading and for any help you can give :) I'm at the end of my rope with trying to figure this out with google... :/ -- For more options, visit http://beagleboard.org/discuss --- You received this message because you are subscribed to the Google Groups "BeagleBoard" group.
