  1. I got libgpiood working at orange pi one. My question is about internal resistors, when line direction is INPUT what about pull_up and pull_down commands ((( ?
  2. thank you very! I`ll try this. it is good info about c++ std11
  3. Hi, thank you for this work! is it suitable for orange pi one? as I can see your lib for piton, but can you share c++ example with interrupts and call back function?

    Orange pi One, interrupts gpio problem

    Anyone() I just test this code with Raspberry Pi 3 and Wiring Pi library, all works perfect() But on orange pi one still this problem(
  5. Hi, my environment is: Orange Pi One ARMBIAN 5.34.171031 nightly Ubuntu 16.04.3 LTS 4.11.12-sun8i WiringPi fork by WereCatf: git clone https://github.com/WereCatf/WiringOP.git -b h3 ./build small c++ programm: #include <stdio.h> #include <string.h> #include <errno.h> #include <stdlib.h> #include <wiringPi.h> #include <pthread.h> static volatile int globalCounter; void myInterrupt(void) { ++globalCounter; printf("InterruptCounter: %5d\n", globalCounter); //digitalRead(7); } int main(void) { if (wiringPiSetup() == -1) { printf("wiringPiSetup Error\n"); } pinMode(7, INPUT); pullUpDnControl(7, PUD_UP); if (wiringPiISR(7, INT_EDGE_FALLING, &myInterrupt) < 0) { fprintf(stderr, "Unable to setup ISR: %s\n", strerror(errno)); return 1; } for (;;) { //main programm code here... } return 0; } Compile: gcc ./isr.c -o wg-daemon.out -lwiringPi -lwiringPiDev -lpthread -lm and run it... but when I put pin 7 in down state (gpio mode 7 down) ISR function begin fires (triggers) continuously ((((((( Here is output : InterruptCounter: 132371 InterruptCounter: 132372 InterruptCounter: 132373 InterruptCounter: 132374 InterruptCounter: 132375 InterruptCounter: 132376 InterruptCounter: 132377 InterruptCounter: 132378 InterruptCounter: 132379 InterruptCounter: 132380 InterruptCounter: 132381 ^C root@orangepione:~/example# but, when I add to ISR function "digitalRead(7);" program works fine ((( Please tell me, what I do wrong

    I`m sorry( I check more carefully, it is "disabled"((( disabledroot@nanopineo:/etc/snmp# cat /proc/device-tree/soc/serial@01c28400/status disabledroot@nanopineo:/etc/snmp# cat /proc/device-tree/soc/serial@01c28800/status disabledroot@nanopineo:/etc/snmp# cat /proc/device-tree/soc/serial@01c28c00/status

    Firstly, I change @script.bin from /boot/bin/nanopineo.bin to /boot/bin/orangepione.bin I rewrite sun8i-h3-orangepi-one.dtb to sun8i-h3-nanopi-neo.dtb (my board is orange pi one) Here it is.... and script.bin. In dts file I change "disabled" -> "okay" files.rar
