wiringPi_Blueberry/README.md

### 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

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



#### 编译安装

```bash
cd wiringOP
./build clean
./build 
```



### Python版本

```bash
# 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：

<img src=".\imgs\pins.png" alt="pins" style="zoom:60%;" />

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：

```c
#ifdef CONFIG_ORANGEPI_ZERO2
int pinToGpioOrangePi [64] =
{
    -1,  // 0
    -1 , -1 ,
    264 , -1 ,
    263 , -1 ,
    256 , 224 ,
    -1 , 225 ,
    226 , 257 ,
    227 , -1 ,
    269 , 270 ,
    -1 , 228 ,
    231 , -1 ,
    232 , 262 ,
    230 , 229 ,
    -1 , 233 ,
    266 , 265 ,
    267 , -1 ,
    268 , 261 ,
    271 , -1 ,
    258 , 234 ,
    272 , 260 ,
    -1 , 259 , // 40
    -1, -1, -1, -1, -1, -1, -1, -1, -1, -1, -1, -1, -1, -1, -1, -1, -1, -1, 
    -1, -1, -1, -1,-1, // 63
};

int physToWpi[64] =
{
	-1,		// 0
	-1, -1,	// 1, 2
	3, -1,  //3, 4
	5, -1,  //5, 6
	7, 8,  //7, 8
	-1, 10, //9,10
	11, 12, //11,12
	13, -1, //13,14
	15, 16, //15,16
	-1, 18, //17,18
	19, -1, //19,20
	21, 22, //21,22
	23, 24, //23, 24
	-1, 26,	// 25, 26
	27, 28,   //27, 28
	29, -1,	//29, 30
	31, 32,	//31, 32
	33, -1, //33, 34
	35, 36, //35, 36
	37, 38, //37, 38
	-1, 40, //39, 40
	// Padding:
	-1, -1, -1, -1, -1, -1, -1, -1, -1, -1, -1, -1, -1, -1, -1, -1,	// ... 56
	-1, -1, -1, -1, -1, -1, -1,	// ... 63
};

char *physNames[64] =
{
  NULL,
  "     3.3V", "5V      ",
  " TWI1_SDA", "5V      ",
  " TWI1_SCL", "GND     ",

  	   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

```c
// 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
