### 说明
2023-08-11 15:53:17 +08:00
2023-08-11 16:55:29 +08:00
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。
2023-08-11 15:53:17 +08:00
2023-08-11 16:55:29 +08:00
### 下载
```bash
apt-get update
apt-get install -y git

### 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:
```c
#ifdef CONFIG_ORANGEPI_ZERO2

2023-08-11 16:55:29 +08:00
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
