WiringPi on OrangePi 2G-IOT[Beta]

yoelmend

thanks for answering

crossmax

Hi,
I'm trying setting up a rs485 on UART2 (PA13 and PA14) and I need a one more gpio to select direction. As I've a custom PCB, I need to use PA1 pin for that, but seems PA1 is blocked for UART1.
How I can change PA1 pin functionality? script.bin file on /boot doesn't exists. My kernel is Linux OrangePI 3.10.62-rel5.0.2 #54 PREEMPT Mon Jun 5 16:46:56 CST 2017 armv7l GNU/Linux

Thanks

Hello,
  In this way I have managed to work 7 gpio as inputs and outputs from gpio0 ..... gpio6. regards

Hi, I'm doing the blink.c test, compile but the LED does not blink, any ideas?

Hi friends:
   I have fix this problem, please update newest source code from github.

Please tell me which boot image to use to work WiringPi.

Gosha

This Ubuntu Server image from download page should work fine

Thnak you.

Have anyone got to blink a simple LED through python or C using the god damn WiringPi library?

I gave up using WiringPi for 2g-iot library.
python-periphery library works very well.
