Hi experts,
I have an OMAP l-138 LCDK board running the linux kernel 3.3.0. So far, i already made and execute on the target board an hello world program using a text editor and the ti-sdk-omapl138-lcdk-01.00.00 on Ubuntu.
I would like to develop a small graphic application to control one LED with the board, and i would like to ask you for some guidance... I am completely lost, i have spend the hole day searching for examples, trying to create and execute a project in code composer, trying to compile some examples, but i haven't no success at all...
There's any example showing how to manipulate a GPIO pin? (I already have activated the GPIO option on the linux kernel menuconfig, under sys/classe/gpio i can see some of these pins)
And for PWM? (i have activated the corresponding option on the kernel menuconfig, but i cannot see any node under /sys/classes/pwm... the pwm modules shouldn't be there?)
If you could show me an example it will be great.
Thanks,
Pedro
