title: How to gain access to gpiochipX
body: <p>We are programming on an Android-based microcontroller and we want to be able to access the gpio pins on the board. Looking through the documentation, the 12 gpio pins we want to use are various pins between # 0-100, however, there are no gpiochips available for it. For instance, gpiochip576 is available, but we do not have need for gpios 576+ and above. We want to gain access to 0-100. Is there an easy way to gain access to them? We found this article: <a href="http://www.pieter-jan.com/node/15" rel="nofollow">http://www.pieter-jan.com/node/15</a> ,that if we are right, seems to gain access to a gpiochip, but requires a lot of c code, and in our case since its android, we need to recompile the kernel and system image and flash it onto the board. Is there an easier way maybe via sysfs(something like echo "14" > /sys/class/gpio/export) or something else so we gain access? Or is our only option modifying the kernel and recompiling. Thank you!</p>
