orangPi zero3 Unable to open GPIO edge interface for pin 0错误修复

gpio: Unable to open GPIO edge interface for pin 0: Permission denied wiringPiISR: unable to open /sys/class/gpio/gpio228/value: No such file or directory

反馈一处代码错误：wiringPi.c文件中wiringPiISR函数中存在bug，导致wiringpi的isr功能不可用，修复后测试可用 · Issue #118 · orangepi-xunlong/wiringOPhttps://github.com/orangepi-xunlong/wiringOP/issues/118wiringPi.c文件的第4535行

sprintf (pinS, "%d", pin) ;

应该改为

sprintf (pinS, "%d", bcmGpioPin ) ;

，否则会报错：“gpio: Unable to open GPIO direction interface for pin XX: No such file or directory”

1.直接从官方库重新拉取源码
 

git clone https://github.com/orangepi-xunlong/wiringOP.git -b next

2.在orangepi系统中更改

cd /usr/src/wiringOP/wiringPi
sudo vim wiringPi.c
