说明

本仓库是将 wiringOP 移植到 MangoPi(H616) 上。需要使用 Orange Pi Zero2的对应的系统镜像。

下载

apt-get update
apt-get install -y git
git clone https://github.com/liuls2002/wiringOP-for-MangoPi-H616.git

编译安装

cd wiringOP
./build clean
./build

Python版本

# 下载 orangepi 提供的代码
git clone --recursive https://github.com/orangepi-xunlong/wiringOP-Python.git
cd wiringOP-Python

# 使用本工程中的代码替换 wiringOP-Python 目录下的 wiringOP
cp -r ./wiringOP ./wiringOP-Python

# 安装tools
sudo apt-get install swig python3-dev python3-setuptools

# Build & install with
python3 generate-bindings.py > bindings.i
sudo python3 setup.py install

相较于 Orange Pi 提供的代码的改动

Mango Pi(h616) 与 Orange Pi Zero2 使用相同的soc（全志H616），所以基于 Orange Pi Zero2 进行移植修改比较方便。

Mango Pi(h616) 引脚对应关系如下：

总共有3种编号：board引脚编号，芯片引脚编号，逻辑引脚编号。控制gpio时一般采用逻辑引脚编号。

==我们需要修改这3者的映射关系。为了简便，我将逻辑引脚编号与board的引脚编号保持一致，使用时需要注意。==

1 修改 gpio/OrangPi.c

将#ifdef CONFIG_ORANGEPI_ZERO2包含的代码替换为如下代码：

#ifdef CONFIG_ORANGEPI_ZERO2
int pinToGpioOrangePi [64] =
{
    -1,  // 0

    -1, -1, -1, -1,-1, // 63
};

int physToWpi[64] =
{
	-1,		// 0
	-1, -1,	// 1, 2

	-1, 40, //39, 40
	// Padding:

	-1, -1, -1, -1, -1, -1, -1,	// ... 63
};

char *physNames[64] =
{
  NULL,

  	   NULL, NULL,
       NULL, NULL,
       NULL,NULL,NULL,NULL,NULL,NULL,NULL,NULL,NULL,
};
#endif

替换 void OrangePiReadAll(void)函数中的部分代码

// 替换前
#elif CONFIG_ORANGEPI_ZERO2
	for (pin = 1 ; pin <= 34; pin += 2)   // orangepi zero2 引出34pin
// 替换后
#elif CONFIG_ORANGEPI_ZERO2
	for (pin = 1 ; pin <= 40; pin += 2)   // mangopi 引出40pin

2 修改 wiringPi/OrangePi.c
