# FCC测试操作手册

## 基本说明

- **触发方式：** 按键对应`P3_2`引脚（对应烧录口`C2CLK`），按键释放后响应，可以通过`IS_CLIENT_BOARD`宏定义切换按键IO口为`P3_3`
- **Keil配置选项：**
    - **MY_Release**：默认触发按键为`P3_3`
    - **CLIENT_Release**：默认触发按键为`P3_2`

## 按键功能

按键功能按照如下顺序循环切换

- **第一次：** 发送调制波，工作频率：`2402MHz`
- **第二次：** 发送调制波，工作频率：`2440MHz`
- **第三次：** 发送调制波，工作频率：`2480MHz`
- **第四次：** 接收状态，工作频率：`2402MHz`
- **第五次：** 发送单波，工作频率：`2402MHz`
- **第六次：** 发送单波，工作频率：`2440MHz`
- **第七次：** 发送单波，工作频率：`2480MHz`
- **第八次：** 发送调制波，工作频率：`2402MHz`~`2480MHz`之间随机选择一个频率发送，间隔`2MHz`，200ms切换一次频率
- **第九次：** 发送调制波，工作频率：`2402MHz`~`2480MHz`之间按照顺序切换频率发送，间隔`2MHz`，200ms切换一次频率

## 日志打印
- 可以通过`P3_1`引脚接收日志打印，波特率`115200`，打印如下：
