[beagleboard] Reading GPIO state in beagle bone black
Hi,
i am new to beagle bone black board..
i flashed new Debian Image to BBB and worked on simple LED blinking program
in C. it is working fine(external LED connected in bread board), in Linux
ubuntu
next example i am trying to control that external LED using external switch
:
like this :
system("echo out > /sys/class/gpio/gpio68/direction) for LED.
system ("echo in > /sys/class/gpio/gpio67/direction) for switch.
using these coding lines i am making LED high and Low in C file
system("echo 1 > /sys/class/gpio/gpio68/value)
system("echo 0 > /sys/class/gpio/gpio68/value)
based on the switch status i need to make LED ON and LED OFF...
how to read the state of GPIO in beagle bone black in C file???
please help me any one
