GPIO access running Android

[dkryder]

I was reading in the sunxi manual for gpio access, and found that the kernel option CONFIG_GPIO_SYSFS must be enabled.  I checked my Android /sys/class/ folder and found that gpio is not there;  the kernel in my Android has not been anabled for CONFIG_GPIO_SYSFS.

It should be easy to enable this option, and frankly, it should be enabled by default.


edit:  PS  I spoke with ayufan about this, and will be updating the configs for his kernel, so that the CONFIG_GPIO_SYSFS will be enabled in his kernel soon...

Eager to see that happen Marcus.  Please keep us in the loop.

This was the main reason for buying the Pine64. I use IOIO OTG usb cards for reading analog/digital inputs from joysticks to android tablet. Another use is information screens (big lcd's) with navigation buttons. It would simplify the hardware setup.

IOIO is a big reason why GPIO was never developed fully on android by google.
