### 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
|
||
```
|
||
|
||
|
||
|
||
### Mango Pi的官方网站

|
||
### 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] =
|
||
{

|

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