Title: AllWinner A10 / A20
Post by: Luca on February 13, 2015, 09:44:57 PM

Hi

did someone implemented GPIO drivers for Olimex LIME series  ?

using the Raspberry.IO drivers only a few pin are available and there are a lot to be used..


tnx in advance

From what I've read up on Raspi, you can reset all GPIO pins to be used but by default there are only a handful that are available (2,3,4,17,18,21,22,23,24,25).  HG has some of these reserved already, so the list is actually shorter.  I'm sure you already knew this, though.  For reference to anyone else, this is the GPIO documentation:

http://www.raspberrypi.org/documentation/usage/gpio/ (http://www.raspberrypi.org/documentation/usage/gpio/)

I'm not sure how you would reset the usage of the GPIO pins and utilize them in HG.

Hi bkenobi,

yes I spent some time to study how Rasp works and how HG manage Rasp gpio...

Then I got an Olimex too :-)

I installed HG on Olimex10Lime and I was able to use some gpio with Raspberry.IO drivers
(yes, simply running the Rasp HG program).

I would like to know if someone wrote an enhanced driver (like CubieTruck/CubieBoard3 coded by Gene) to use Olimex-lime gpio and maybe some of his i2c...


that's all :-)

many thanks
L.
