Before installing Wiring Pi I tested a I2C device and it was working well.

After install I am getting a communication error on send error.

Does something need to be reconfigured on the I2C channel to restore usability?

Hello,
Please, add support for Orange Pi One Plus (SoC Allwinner H6).

I tried it for orangepi 5B and I am getting the following error .

[sudo] password for orangepi:
piBoardRev: Unable to determine board revision from /proc/cpuinfo
-> No "Hardware" line
-> You may want to check:
-> http://www.lemaker.org/

I want to switch PIN1 to PWM mode but it failed.

This is the output:

root@DietPi:~# gpio mode 1 pwm
the pin you choose is not surport hardware PWM
you can select PI3 for PWM pin
or you can use it in softPwm mode

When booting an Orange Pi the default pin state appears to be HIGH.

On a Raspberry Pi there is a /boot/config.txt file to change the initial boot state.

Is there a way set the boot state to LOW on the Orange Pi?

I've tried the following code (after echo'ing 3 > /sys/class/gpio/export)

#include <stdio.h>
#include <wiringPi.h>
#include <stdint.h>
#define TRIGGER 2
#define ECHO 3

int IRQcount = 0;

void irq(void) {
	//printf("Falling edge\n");
	IRQcount++;
}

int main() {
	wiringPiSetup();
	pinMode(TRIGGER, OUTPUT);
	pinMode(ECHO, INPUT);
	//Next line fails miserably
	wiringPiISR(ECHO, INT_EDGE_RISING, &irq);	
	for (;;) {
		printf("On [%i]\n", IRQcount);
		digitalWrite(TRIGGER, HIGH);
		delayMicroseconds(4000000);
		printf("Off [%i]\n", IRQcount);
		digitalWrite(TRIGGER, LOW);
		delayMicroseconds(4000000);
	}
	return (0);
}```

The interrpt is invoked, but then it won't ever stop forever, hitting the callback until I don't stop the program.
It's not bouncing or anything it really keeps beeing called forever.

Is there a way to disarm the irq?

hi
how should I use WiringOp on Officially android for orange pi
I added this library to my android project and built that with NDK and run on my orange pi Pc
but when I use wiringPiSetup I get an exception (maybe because cannot access to /dev/mem)
and when I call wiringPiSetupSys instead, no exception but that is not working
how should I do that?
not that my android is rooted

The compilation is completed with several warnings, when you use the command gpio appears this message :
gpio mode 7 in
piBoardRev: Unable to determine board revision from /proc/cpuinfo
-> No "Revision" line
-> You may want to check:
-> http://www.lemaker.org/

I'm getting

piBoardRev: Unable to determine board revision from /proc/cpuinfo -> No "Revision" line -> You may want to check: -> http://www.lemaker.org/

Does it support Orange Pi 4G IOT ?

After installed Ubuntu image and downloaded & installed WiringOP, the "gpio readall"
command does not work properly. After printed part of table header, there is an error
message:
Orange Pi+-[ 490.969604] Unhandled fault: external abort on non-linefetch
(0x008) at 0xb6fcc000. The table is short (just header + single line) and is followed
by "Bus error" message, And by the way -- header pins 1 and 2 on i96 are connected to GND, so the printed line is wrong (shows 3.3V and 5V in V columns) ....

Running gpio under root identity gives the same result. Rest of the Ubuntu system
seems to work as expected.

orangepi@orangepii96:~/WiringOP$ gpio readall

Sorry it's my miss take.
Please close this issue.
