In the software posted the following is part of wiringPi.c but with orangePi the gpio module will create a path "sys/class/gpio_sw" in sysfs. Is this just a simple fix in the path or will this be more complicated?

if (sysFds [bcmGpioPin] == -1)
  {
sprintf (fName, "/sys/class/gpio/gpio%d/value", bcmGpioPin) ;
if ((sysFds [bcmGpioPin] = open (fName, O_RDWR)) < 0)
   return wiringPiFailure (WPI_FATAL, "wiringPiISR: unable to open %s: %s\n", fName, strerror (errno)) ;
  }

A small reference to me would have been nice

Adaptation to H3 orange pi was made by me.

Next Time please

Yeah, that's not nice!

@jacer if you are @zhaolei fix this!
If not:
@sauberpauli if you want I can fork this thing and put the reference/credit to you or I can help you if you want to fork it yourself.

I don't take credit for this. I provided the original github source which contains the author's email. If the author is you, then kudos goes to you.

Zhaolei is the author. I asked his permission to post here.

I have adapted the wiringpi library (http://wiringpi.com/) to the Orange Pi PC.
Basis was the adaptation of https://github.com/LeMaker/WiringBP "banana pi pro" library.

Changes ...
1. CPU from A20 to H3
2. Header Pinout
3. /dev/i2c device
4. gpio utility

Thanks @sauberpauli very nice work.

I'have a problem with ISR using Debian, i load the gpio module with the following command:

modprobe gpio-sunxi

Copy code

and the GPIO device files are not /sys/class/gpio but /sys/class/gpio_sw/

How can I use the ISR with my orange pi PC with Debian and correct the gpio code?

Thanks,
Francesco

ISR is is not possible with the module gpio-sunxi.

Look at
OrangePI-Kernel/linux-3.4/drivers/gpio/gpio-sunxi.c ...
that is the Source Code of the Kernel-Module. The gpio-sunxi kernel source code requires an adjustment to interrupt handling.
This is actually not done for the Allwinner H3

Hello, I am using Loboris Debian XFCE img that works stable on my Orange PI Plus.
Sorry for my English. I am Russian user.

I can not connect and use a 433 MHz transmitter and receiver.
I wiringOP use the lib. (git,make install)
connect to pin 1 and another. (5v,gnd,wpi 1-0)
433Utils used.
heard that WiringOP no interrupts.
tell me how to use the 433 MHz and run?
