The Dragino MS12 has five GPIOs pins avaible on the 2x8 connctor for easy use. They are GPIO0~ GPIO4. these GPIOs connects to the Atheros ar2317 directly and can be control via openwrt command gpioctl command.
The input and ouput voltage of these GPIO is 3.3v.
gpio command:
root@dragino:~# gpioctl gpioctl dirin|dirout|get|set|clear gpio dirin: configure GPIO pin as input dirout: configure the GPIO pin as output get: get the GPIO status: HIGH or LOW set: set the GPIO to HIGH clear: set the GPIO to LOW
examples:
Simply connet the GPIO4 and LED pin via a wired. LED1 will be on if there is a LOW singal. you can type:
root@dragino:~# gpioctl dirout 4 using gpio pin 4 ==> this will set the GPIO4 to output and default is LOW. this will turn on LED1 root@dragino:~# gpioctl set 4 using gpio pin 4 ==> set GPIO4 to HIGH and turn off LED1.
