LEDs

The logic is in the RPi.GPIO-PineA64-master/source/common.c file, but of course PL7 isn't there, although it could be added later.
For now, I would go with the sysfs, where GPIOs can be exported, set direction, and then state value.
The pin number would be for PL7 is ("L"-"A")*32+7 = 359 ... I've verified on real hardware and it is working.

echo 359 > /sys/class/gpio/export
echo out > /sys/class/gpio/gpio359/direction
echo 0 > /sys/class/gpio/gpio359/value

   

@martinayotte, thanks much... I was in the process of studying the codes for RPi.GPIO/ you saved me a ton of work figuring out the 'number' from name, bank, pin &c.  I did have to make the change above to include the /gpio folder under /class (I assume it was just a typo... I tried this on the debian image, have not tried it on the ubuntu image yet--  see above).  Again, thanks it was a big help !

@longsleep, thanks for the formula script to go from name -> pin number !  voila, wishes do come true !  


I should note (even though its probably obvious) the LED lights on value = 0;  because we're providing the ground shot for DCDC1. 

I won't be soldering my test LED in; going to use a smaller (3mm) green LED coming soon.

edit:  here's the final 3mm green:
