Mysensors Gateway on OrangePi (Zero) (opi)
-
Build the RF24 lib, without erros on the OPI Zero. and am now able to start the tools and radio seems to be recognised!. (was a faulty breadboard wire.... :( )
Used the follwing to for the radio:
RF24 radio(2,0);Output from gettingstarted:

@marceloaqno and everyone else involved in this effort: great work! I love when people come together to solve a problem.
@marceloaqno
@mfalkvidd @Tag @pansen @Reza @mihai.aldea @hausingerWooow woow woow !!!
Only few days "off" and the problem to make work Mysensors on OPI are solved.
So many many thanks to all people here that have been involved to make that OPI good little boards can work with Mysensors.
This is the proof that when good people join can reach the most difficult achievements and all humanity can benefit.
Awesome work !

Great work!!! the GPIO part most probably needs some additions for OPI zero on the topic of the spidev1.0 driver and the GPIO pins, send it to you once i got everything documented.
Really many thanks for your hard work here!!

You need to create the files after each boot.
After the modprobe, Issue this command:
sudo for A in 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16; do echo "$A" > /sys/class/gpio/export ; doneThis will get you the files.
