WiringOP-Zero

This library is a fork of WiringPi / WiringOP libary by xpertsavenue for the Orange Pi Zero with 26 pin GPIO header

A well known bug of an "eternal loop" occuring for Interrupt bug is fixed.

This is a modified WiringPi for specially OrangePi Zero.

GPIO, SPI and Interrupt are working properly!

SPI is tested on Armbian with legacy kernel:
    The SPI channel 0 is used for SPI Flash and channel 1 is available
    for use in GPIO pins...
    > bin2fex /boot/script.bin script.fex
    > nano script.fex
      Add following lines:
          [spi1_para]
          spi_used = 1
          spi_cs_bitmap = 1
          spi_cs0 = port:PA13<2><1><default><default>
          spi_sclk = port:PA14<2><default><default><default>
          spi_mosi = port:PA15<2><default><default><default>
          spi_miso = port:PA16<2><default><default><default>

          [spi_devices]
          spi_dev_num = 2

          [spi_board1]
          modalias = "spidev"
          max_speed_hz = 33000000
          bus_num = 1
          chip_select = 0
          mode = 0
          full_duplex = 1
          manual_cs = 0

    > fex2bin script.fex bin/orangepizero.bin
    > reboot -i

To control red LED on the board run for example this:

gpio write 30 1 

and to turn off this

gpio write 30 0 

Thanks to zhaolei, who created the base libary for this one!
