gpio15 gpio168 gpiochip160 gpiochip64
gpio144 gpio16 gpiochip0 gpiochip192 gpiochip96
gpio145 gpio164 gpiochip128 gpiochip32
I want to use the gpio145 (I am not using and LCD).
That would be of great help.
Hi Roque, You can configure GPIO pins for input or output: http://gumstix.org/software-development/how-to/250-gpio.html Additional useful info can be found here: https://www.kernel.org/doc/Documentation/gpio/sysfs.txt If you log into your Overo command line, you can see what GPIOs you have available by running the command: ls /sys/class/gpio By using the "edge" property of sysfs GPIOs, you can use poll(), select() or epoll() to efficiently wait for GPIO input events. The Overo has lots of pins that you can use as GPIOs. The thing is, lots of them are assigned to other functions by default. But, you can change that by adjusting the pin multiplexing ("pin mux") in the kernel and/or U-boot to use them. Also, if you share more details about your application it would people here to provide useful info.

I want to set up a pin of an overo fire as a timer in capture mode but I do not know where to look for this information. I have read a lot of articles and datasheets but it does not work for the distribution that I am using, Linaro (Yocto Project).Could you help me with this?Best regards--Roque LoraGraduate Research Assistant of Electrical EngineeringAggieAir Flying Circus (http://aggieair.usu.edu/)Utah State UniversityLogan, UT, USA
