PWM not found in Occidentalis v0.2

Thu Jan 02, 2014 7:54 am

I'm trying to get my DC motor to work according to this tutorial: http://learn.adafruit.com/adafruit-rasp ... r/software

I'm running Occidentalis v0.2 (from day 1, which was some 4 months ago) and never had a similar issue.

Code: Select all

$ sudo ls /sys/class/rpi-pwm
ls: cannot access /sys/class/rpi-pwm: No such file or directory
Also:

Code: Select all

$ ls -lR /sys/class | grep -c rpi-pwm
0
Seems PWM kernel module is not installed!? How come and how can I fix that, please?

No idea about Occidentalis. I have a vague feeling it no longer serves a need.

Have you tried one of the other methods of generating PWM? There are plenty of alternatives, more than good enough for motor speed control.
