Pi GPIO

I'm not particularly into using python so I'm looking at the following for C++/C options for accessing the GPIO pins:

• http://elinux.org/RPi_GPIO_Code_Samples
• http://abyz.co.uk/rpi/pigpio/examples.html#Misc_code
• http://wiringpi.com/download-and-install/
• http://www.hertaville.com/introduction-to-accessing-the-raspberry-pis-gpio-in-c.html

After looking at the above options I am going to try

• WiringPi
• sysfs

sysfs looks to be very simple and straight forward and idea for controlling something that is just a simple on/off switch.

WiringPi has a bunch of additional modules that provide additional functionality around SPI and I2C interfaces which will be needed for reading and writing to sensors.
