This didn't work, BUT, the below did:

The general proceeding is described in https://linux-sunxi.org/GPIO

The GPIO pins are accessed via the sysfs file system. For enabling a specific pin it has to be exported into /sys/class/gpio/export

for pin PA1 the command would be echo 1 > sys/class/gpio/export. The pin number is calculated by the following formula :

 (position of letter in alphabet - 1) * 32 + pin number

PA1 has pin number ('A' is the 1st letter ) 1, PB2 has pin number 34 ('B' is 2nd letter ), PG7 has pin number 199( 'G' is 7th letter (7-1) * 32+7=199 )

the positions on the physical header are different again, cf. the graphic below

so for enabling PG7 that is pin 40 on the physical header can be used
(# echo "out" >/sys/class/gpio/gpio5/direction first)
  echo 199 > sys/class/gpio/export

Then you can run `echo "1" >/sys/class/gpio/gpio2/value` to turn it on and `echo "0" >/sys/class/gpio/gpio2/value` to turn it off.

You need to use a VCC3 pin and an IO pin for this. Refer to this diagram (Page 15): http://linux-sunxi.org/images/7/7e/ORANGE_PI-ONE-V1_1.pdf

I used pin 2 for VCC3 and pin 22 for IO.
