# 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>
spi_sclk = port:PA14<2>
spi_mosi = port:PA15<2>
spi_miso = port:PA16<2>
[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!
