Just to tell you. I use PWM on BBB and encoders and they are working quite well.
You have to use kernel 3.8.13 You have to patch pwm test using https://github.com/SaadAhmad/beaglebone-black-cpp-PWM<https://github.com/Teknoman117/beaglebot> and if you have encoders try https://github.com/Teknoman117/beaglebot all that you need is: http://www.phys-x.org/rbots/index.php?option=com_content&view=article&id=106:lesson-3-beaglebone-black-pwm&catid=46:beaglebone-black&Itemid=81 Il giorno mercoledì 11 dicembre 2013 14:18:10 UTC+1, Sika ha scritto: > > HI Ian, > > Sorry to say it did not work for me either.
