# 外设驱动测试用例
|
||||
|
||||
## 1、介绍
|
||||
|
||||
这个软件包包含一些外设设备操作的例程。
|
||||
|
||||
### 1.1 例程说明
|
||||
|
||||
| 文件 | 说明 |
|
||||
| ---------------- | ------------------------------- |
|
||||
| adc_vol_sample.c | 使用 ADC 设备转换电压数据 |
|
||||
| can_sample.c | 通过 CAN 设备发送一帧，并创建一个线程接收数据然后打印输出。 |
|
||||
| hwtimer_sample.c | 使用 硬件定时器定时 |
|
||||
| i2c_sample.c | 使用 i2c 设备进行读写 |
|
||||
| pm.c | 反复进入不同程度的睡眠。 |
|
||||
| led_blink_sample.c | 使用 pin 设备控制 LED 闪烁 |
|
||||
| pin_beep_sample.c | 使用 pin 设备控制蜂鸣器 |
|
||||
| pwm_led_sample.c | 使用 pwm 设备控制 LED 的亮度 |
|
||||
| rtc_sample.c | 使用 rtc 设备设置年月日时分秒信息 |
|
||||
| spi_sample.c | 使用 spi 设备进行读写 |
|
||||
| uart_sample.c | 使用 serial 设备中断接收及轮询发送模式收发数据 |
|
||||
|
||||
### 1.2 依赖
|
||||
|
||||
依赖设备管理模块提供的设备驱动。
|
||||
|
||||
## 2、如何打开 外设驱动测试用例
|
||||
|
||||
使用 外设驱动测试用例 需要在 RT-Thread 的menuconfig中选择它，具体路径如下：
|
||||
|
||||
```
|
||||
Hardware Driver Config --->
|
||||
Peripheral Driver test example--->
|
||||
```
|
||||
|
||||
## 3、使用 外设驱动测试用例
|
||||
|
||||
在打开 Peripheral Driver test example 后，当进行 BSP 编译时，选择的软件包相关源代码会被加入到 BSP 工程中进行编译。
|
||||
|
||||
## 4、注意事项
|
||||
|
||||
暂无。
