WiringOP for Orange pi zero

Hello,
Is there a WiringOP version for Opi zero.
Or is there a screenshot for the proper mapping.

Thanks

Hi,
I am not sure but I guess you want the 26 pin GPIO layout. If so you find that here

If you mean by "WiringOP" a version of the OPI zero with 2x13 pins you would have to ask the OPI guys.
I found only this 2x13 pin header on Aliexpress.
Edit:
I also found those 2x40. But I am sure the are cutable

Thanks,
I have installed that connector and now want to control the IO s with a library, if possible WiringPi, WiringOp etc. I compile a led blink example for PC PLUS (H3) and able to toogle it by toggling GPIO_0 (wiringOp numbering), interestingly the same app works for Opi zero too (H2).
But I have problems with other GPIO's naming convention etc. And also not sure if my downloaded version of WiringOp(h3) can control SPI or (h2)correctly.

Any tips? Thanks.

Ok I have somewhat figured it out. Pins seem to be mapped properly, I will check further and report back.

So one more question, is it possible to use SPI-CS0 pin as GPIO? (Opi PC or Opi Zero).

Hello,

I also have trouble to find out how to use the gpio in the orange pi zero. Likely I installed the wrong kind of wiringOP. Somewhere i had to choose between an orange pi pc and another orange pi model. there was no tab for choosing the zero. What should I use to program the zero in C language?

Cordially,

Eduard

Hi, I have sucessfully control GPIO on OPi PC, with this library:
https://github.com/zhaolei/WiringOP

It is for H3 SoCs but I bet that it can be used on H2 (OPi zero).

Instructions of installation:

1 - Get the repo:
git clone https://github.com/zhaolei/WiringOP.git -b h3
2 - Install it:
cd WiringOP
sudo chmod +x ./build
sudo ./build
3 - Check the correct installation:
cd ..
gpio readall

Copy the Code

Note: Dont forget the lwiringPi flag when compile a code:
gcc -o blink blink.c -lwiringPi

Hi,

I am using git clone https://github.com/zhaolei/WiringOP.git -b h3 to control GPIO on Orange Pi Zero.

It works fine for GPIO 0, 2, 3, 7, 8, 9 But does not work for GPIO 1, 4, 5, 11.

Is it because or wrong mapping ?

No one can reply that you don't exhibit your cord.

Got the difference between OPI PC and OPI Zero mapping. Its working fine now.
