# v3s测试程序
测试模块化的代码专用

















# 摄像头调试记录
## 手动控制补光灯
```bash
# 手动调试io

# 导出GPIO152
echo 152 > /sys/class/gpio/export

# 设置为输出模式
echo out > /sys/class/gpio/gpio152/direction

# 控制输出高电平（打开补光灯）
echo 1 > /sys/class/gpio/gpio152/value

# 控制输出低电平（关闭补光灯）
echo 0 > /sys/class/gpio/gpio152/value

# 取消导出
echo 152 > /sys/class/gpio/unexport
```

## 摄像头参数

## 调试方法
### 调试前
目标板输入指令运行程序：`gdbserver 192.168.1.10:2000 test_program` `gdbserver 127.0.0.1:2000 test_program`


### 方法1
在开发机上输入指令`gdb-multiarch`，此时会进入gdb，并继续输入
```bash
target remote 192.168.1.10:2000            # 连接远程目标 ip 和端口
set sysroot /home/zh/nfs/rootfs             # 设置根文件系统路径
handle SIGUSR1 nostop noprint               # 设置遇到 SIGUSR1 信号量不要暂停
handle SIGUSR2 nostop noprint               # 设置遇到 SIGUSR2 信号量不要暂停
continue                                    # 继续运行程序
```

或者不想每次都输入以上指令的话，可以把指令写到一个.gdb 文件内，如：`gdb_commands.gdb`
然后直接使用指令 `gdb-multiarch -x gdb_commands.gdb` 就行了

### 方法2
使用vscode调试（图形化更方便）
文件`launch.json`：
```json
{
  "version": "0.2.0",
  "configurations": [
    {
      "name": "v3s Debug",
      "type": "cppdbg",
      "request": "launch",
      "program": "${workspaceFolder}/software/build/bin/test_program",
      "miDebuggerServerAddress": "192.168.1.10:2000",
      "miDebuggerPath": "/usr/local/arm/gcc-linaro-6.3.1-2017.02-x86_64_arm-linux-gnueabihf/bin/arm-linux-gnueabihf-gdb",
      "stopAtEntry": false,
      "cwd": "${workspaceFolder}",
      "externalConsole": false,
      "MIMode": "gdb",
        "setupCommands": [
        {
        "description": "Enable pretty-printing",
        "text": "-enable-pretty-printing",
        "ignoreFailures": true
        }
      ]
    }
  ]
}
```
