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)) ;
  }

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.

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:

  1. 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
