OrangePi 2G-IOT - GPIO Pins. Help

surfero75

I wolud like to use 40 pins gpio pins, for example witch oled displays, arduino sensors (dht22, mq135...) . Is there any way to do this? Adafruit libraries for orange pi h3, a31, etc.. dont works. Help please..

I suggest you could install wiringPi
H3 WiringPi GPIO（c lib）:      
git clone https://github.com/kazukioishi/WiringOP.git -b h3
H3 WiringPi GPIO（pythonlib）：  
Download link: http://www.orangepi.cn/orangepib ... &highlight=gpio

DHT11 could refer to:

I have compiled H3 WiringPi GPIO（c lib, now i have this error:


./gpio/gpio readall

I think this libraries aren,t for orange pi 2G IoT SOC SoC – RDA Micro 8810PL

¿any solution or ideas for use Orange Pi 2G IoT GPIO ports or this harwdware is impossiible to use?

No news about this? Thanks

WiringOP doesn't really work, because the lazy OrangePi devs couldn't be arsed to do it properly. Whole functions are rendered no-op, such as pinModeAlt. I've made forks here and here that are a bit more usable. You might want to take a look.
If they don't work on your board, then I suggest demanding a refund. If the devs can't provide working software for their product, they shouldn't be selling the product. Get it refunded and buy a Raspberry instead.

Did they test the GPIO function at the factory before making this board? I can not believe that anything goes to the market without the right drivers

Hello

I read in another topic about that Xunlong working on gpio support,

1. have any news when will realize beta version?
2. any news about work stage?
3. are SPI and I2C work in this stage?
