## 按键灭灯实践

### 灭了怎么点都不亮
|
||||
因为按键按灭就没再点亮

在key线程循环开始每次点亮？
|
||||
### 灯轻微闪烁，几乎看不出
|
||||
不能及时获取？用无等待获取信号量？
|
||||
### 还是一样……
|
||||
因为采用了延时防止误触，判断是否按下按键花了一点时间
|
||||
~~只要知道按键没有按下就亮灯就行~~
|
||||
在下次判断按键没按下之后再亮灯
|
||||
### 居然在按键的线程在控制led

# 设备驱动
|

## I/O设备框架概念
|
||||
### SPI驱动和设备驱动分离，提供统一的API：
|
||||
• 更换 MCU 只需要改变对应的对接驱动
|
||||
• 重新驱动设备，只需要重新编写设备驱动相关的代码
|
||||
• 同一 API 接口，学习成本低
|
||||
• 分离后设备驱动可以入库，供公司其他项目使用，减少碎片化开发，防止反复造轮子
|
||||
• 代码框架会变复杂，但是从上面的优点来看是值得的
|
||||
|
||||
### I/O框架
|
||||
显示屏、串口通信、flash、SD卡、以太网接口

I/O 口使用模式：
|

- GPIO（General Purpose Input Output（通用输入 / 输出））,

- 功能复用I/O（如 SPI/I2C/UART 等）

- rt_pin_write()
|

- rt_pin_read()

- rt_pin_attach_irq() ：绑定引脚中断回调函数
|
||||
- rt_pin_irq_enable() ：使能引脚中断
|
||||
- rt_pin_detach_irq() ：脱离引脚中断回调函数

## I2C总线
|
||||
[官方文档链接](https://www.rt-thread.org/document/site/#/rt-thread-version/rt-thread-standard/programming-manual/device/i2c/i2c)
|
||||
I2C 是 Inter-Integrated Circuit 的简称，读作：I-squared-C
|
||||
I2C 总线传输数据时只需两根信号线，一根是双向数据线 **SDA**（serial data），另一根是双向时钟线 **SCL**（serial clock）。SPI 总线有两根线分别用于主从设备之间接收数据和发送数据，而 I2C 总线只使用一根线进行数据收发。不同于 SPI 一主多从的结构，它允许同时有多个主设备存在
|
||||
RTT用GPIO模拟I2C
|
||||
|
||||
|
||||
应答信号： 每传输完成一个字节的数据，接收方就需要回复一个 ACK（acknowledge）。写数据时由从机发送 ACK，读数据时由主机发送 ACK。当主机读到最后一个字节数据时，可发送 NACK（Not acknowledge）然后跟停止条件。

## 我的实践
|
||||
### 读取传感器数据，上传到阿里云
|
||||
|
||||
### 1. 使用AHT10软件包采集温湿度并上传到阿里云
|
||||
|
||||
（合并头两个代码），拼接字符串时我用了`sprintf`，其实应该也可以样例原有的`HAL_Snprintf`的
|
||||
|
||||
### 2. 将font分区给挂载上。在温湿度上传上传云端的同时，将数据同步放在文件系统处，
|
||||
文件名为：Data.txt；文件内容：
|
||||
> Temp：XX ; Humi：XX ; Count： 1（自上电起所采集的数据次数）
|
||||
Temp：XX ; Humi：XX ; Count： 2（自上电起所采集的数据次数）
|
||||
Temp：XX ; Humi：XX ; Count： 3（自上电起所采集的数据次数）
|
||||
|
||||
|
||||
在`drv_filesystem.c`中实现挂载font
|
||||
``` c
|
||||
fal_init();
|
||||
fal_blk_device_create("font");
|
||||
/* 创建目录 */
|
||||
ret = mkdir("/fal/test", 0x777);
|
||||
if (ret < 0)
|
||||
{
|
||||
/* 创建目录失败 */
|
||||
rt_kprintf("dir error!\n");
|
||||
}
|
||||
else
|
||||
{
|
||||
/* 创建目录成功 */
|
||||
rt_kprintf("mkdir ok!\n");
|
||||
}
|
||||
/* 挂载块设备"font"到 DFS 目录/fal/test中 */
|
||||
if (dfs_mount("font", "/fal/test", "elm", 0, 0) == 0)
|
||||
{
|
||||
LOG_I("font initialized!");
|
||||
}
|
||||
else
|
||||
{
|
||||
dfs_mkfs("elm", "font");
|
||||
if (dfs_mount("font", "/fal/test", "elm", 0, 0) == 0)
|
||||
{
|
||||
LOG_I("font initialized!");
|
||||
}
|
||||
else
|
||||
{
|
||||
LOG_E("Failed to initialize font!");
|
||||
LOG_D("You should create a filesystem(font) on the block device first!");
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
接着文件末尾添加数据(Data.txt)
|
||||
|
||||
|
||||
``` c
|
||||
void make_file()
|
||||
{
|
||||
//文件描述符
|
||||
int fd;
|
||||
|
||||
//用只写方式打开文件,如果没有该文件,则创建一个文件
|
||||
fd = open("/fal/test/Data.txt", O_WRONLY | O_CREAT | O_APPEND); //和原来相比，只是把O_TRUNC参数更改为O_APPEND，即更改为打开后，如果再进行写入，将从文件的末尾位置开始写。
|
||||
// rt_kprintf("\n%f %f tmp:%s\n",Humi,Temp,String);
|
||||
//如果打开成功
|
||||
if (fd >= 0)
|
||||
{
|
||||
//写入文件
|
||||
write(fd, tmp, sizeof(tmp));
|
||||
|
||||
// rt_kprintf("Write done.\n");
|
||||
|
||||
//关闭文件
|
||||
close(fd);
|
||||
}
|
||||
else
|
||||
{
|
||||
rt_kprintf("File Open Fail.\n");
|
||||
}
|
||||
|
||||
|
||||
return;
|
||||
}
|
||||
```
|
||||
### 3. 利用云端给开发板发送指令然后实现小灯翻转
|
||||
```c
|
||||
rt_pin_mode(GPIO_LED_R, PIN_MODE_OUTPUT);
|
||||
//topic_info->payload 为发送的内容，可以据此设置命令
|
||||
if(rt_pin_read(GPIO_LED_R) == PIN_HIGH)
|
||||
{
|
||||
// rt_kprintf("LED_R should be ON\n");
|
||||
rt_pin_write(GPIO_LED_R, PIN_LOW);
|
||||
}
|
||||
else
|
||||
{
|
||||
// rt_kprintf("LED_R should be OFF\n");
|
||||
rt_pin_write(GPIO_LED_R, PIN_HIGH);
|
||||
