EEWorld！](http://https://bbs.eeworld.com.cn/thread-1291521-1-1.html "入门任务（必做）：搭建环境并开启第一步串口打印Hello EEWorld！")** 软件流程图 ```flow st=>start: 开始 op1=>operation: 初始化串口1波特率为9600 op=>operation: 串口打印 op2=>operation: 延时1秒 op3=>operation: loop() st->op1->op3->op->op2->op3 ``` 主要使用串口1的输出打印，代码如下所示 ``` void setup() {   // put your setup code here, to run once:   //初始化串行通信，设置波特率为9600bps   Serchuial.begin(9600); } void loop() {   // put your main code here, to run repeatedly:   //向串口打印“Hello EEWorld！”   Serial.println("Hello EEWorld!");   //等待1秒   delay(1000); } ``` 输出串口监控如图所示 ### 二、基础任务 帖子地址：**[开发板基础功能测试（DAC,OPAMP,ADC)](http://https://bbs.eeworld.com.cn/thread-1291975-1-1.html "开发板基础功能测试")** #### 驱动12x8点阵LED 软件流程图 ```flow st=>start: 开始 op1=>operation: 初始化串口1波特率为115200 op=>operation: 初始化LEDMatrix op2=>operation: 定义happy[]和heart[] op4=>operation: loop() op3=>operation: 输出happy等待1s op5=>operation: 输出heart等待1s st->op1->op->op2->op4->op3->op5->op4 ``` 根据用户教程Using the Arduino UNO R4 WiFi LED Matrix这个说明手册，我们可以知道点阵LED的显示原理，每一个LED代表一位，一共有96个LED，发送一次LED数据至少96位，手册中发送一个frame，内有96个点，例如 ``` unsigned long frame[] = {   0x3184a444,   0x42081100,   0xa0040000 }; ``` 发送数据时需要发送转换后的二进制数值， 0x3184a444（110001100001001010010001000100） 0x42081100（1000010000010000001000100000000） 0xa0040000（10100000000001000000000000000000） 用串口发送二进制方式发送数据， ``` for (int b = 0; b < 3; b++) {     Serial.println(frame, BIN); } ``` 代码如下 ``` #include "Arduino_LED_Matrix.h" ArduinoLEDMatrix matrix; void setup() {   // put your setup code here, to run once:   //初始化串行通信，设置波特率为115200bps   Serial.begin(115200);   matrix.begin(); } const uint32_t happy[] = {   0x19819,   0x80000001,   0x81f8000 }; const uint32_t heart[] = {     0x3184a444,     0x44042081,     0x100a0040 }; void loop() {   // put your main code here, to run repeatedly:   //向串口打印“Hello EEWorld！”   //Serial.println("Hello EEWorld!");   matrix.loadFrame(happy);   //等待1秒   delay(1000);   matrix.loadFrame(heart);   delay(1000); } ``` 实际测试视频 [localvideo]3e45d97e70f578c770f499fa3dc6056c[/localvideo] #### DAC生成正弦波 软件流程图 ```flow st=>start: 开始 op1=>operation: 初始化串口1波特率为115200 op=>operation: 初始化正弦波 op4=>operation: loop() op3=>operation: 从A5脚输入 op5=>operation: 输出等待1s st->op1->op->op4->op3->op5->op4 ``` 代码如下 ``` #include "analogWave.h" // Include the library for analog waveform generation analogWave wave(DAC);   // Create an instance of the analogWave class, using the DAC pin int freq = 10;  // in hertz, change accordingly void setup() {   Serial.begin(115200);  // Initialize serial communication at a baud rate of 115200   wave.sine(freq);       // Generate a sine wave with the initial frequency } void loop() {   // Read an analog value from pin A5 and map it to a frequency range   freq = map(analogRead(A5), 0, 1024, 0, 10000);   // Print the updated frequency to the serial monitor   Serial.println("Frequency is now " + String(freq) + " hz");   wave.freq(freq);  // Set the frequency of the waveform generator to the updated value   delay(1000);      // Delay for one second before repeating    } ``` 用示波器从A0上测试 [localvideo]c2980e044f78ffe7ef7991fb42664ec2[/localvideo] #### OPAMP放大DAC信号 硬件接线图，因手里没有合适的电阻，就用了2个3.3K，一个1K的电阻进行的放大设计。 示波器测试如下所示 [localvideo]7c22ead58820d6e4f058222aef2c82c1[/localvideo] #### ADC采集并且打印数据到串口上传到上位机显示曲线 流程图 ```flow st=>start: 开始 op1=>operation: 初始化串口1波特率为9600 op=>operation: 设置模拟输入14位 op4=>operation: loop() op3=>operation: 从A3脚输入 op5=>operation: 串口输出等待0.1s st->op1->op->op4->op3->op5->op4 ``` 程序代码 ``` void setup(){   Serial.begin(9600);   analogReadResolution(14); //change to 14-bit resolution } void loop(){   int reading = analogRead(A3); // returns a value between 0-16383   Serial.println(reading);   delay(100); } ``` 串口监视曲线如图所示 ### 三、进阶任务 帖子地址：**[MQTT协议接入到开源的智能家居平台HA（HomeAssistant）](http://https://bbs.eeworld.com.cn/thread-1292883-1-1.html "MQTT协议接入到开源的智能家居平台HA（HomeAssistant）")** 这一篇我完成的比视频老师的有些早，不过原理都是一样的。我的实现思路：在虚拟机里面安装了docker HA和mosquitto，使用 Docker 运行一个Python容器，并将其配置为一个简单的HTTP服务器，这样直接访问虚拟机的IP地址就可以访问HA了。 #### 1、下拉home-assistant镜像 ```shell Sudo docker run -d \   --name homeassistant \   --privileged \   --restart=unless-stopped \   -e TZ=Asia/Shanghai \   -v /home/alientek/homeassistant:/config \   -v /run/dbus:/run/dbus:ro \   --network=host \   ghcr.io/home-assistant/home-assistant:stable ``` #### 2、下拉eclipse-mosquitto镜像 ```shell sudo docker pull eclipse-mosquitto ``` 启动镜像，注意启动前需要配置，查看我的帖子。 ```shell sudo docker run -it --name=mosquitto --privileged -p 1883:1883 -p 9001:9001 -v /mosquitto/config/mosquitto.conf:/mosquitto/config/mosquitto.conf -v /mosquitto/data:/mosquitto/data -v /mosquitto/log:/mosquitto/log -d  eclipse-mosquitto ``` #### 3、使用Docker运行一个Python容器 ```shell docker run --name bjbook -p 8000:80 -it --rm python:3  python -m  http.server ``` #### 4、浏览器打开HA并配置 a、浏览器输入http://:8123 b、配置mqtt 设置->设备与服务->搜素MQTT->点击后 配置MQTT #### 5、使用mqtt客户端进行测试 连接MQTT，按照homeassistant自动发现规则发送数据。 面板上可以看到发送的数据了。 ## 四、扩展任务 帖子地址：**[UNO R4 WIFI传感器上传HA](http://https://bbs.eeworld.com.cn/thread-1293037-1-1.html "UNO R4 WIFI传感器上传HA")** #### 1、Arduino安装PubSubClient #### 2、用MQTTX客户端注册设备（注：可以在ha界面里面自行配置） ```shell Config No.1： config topic: homeassistant/sensor/HA/HA-UNO-R4-WIFI-currentTemp/config payload: { "device_class": "temperature",

秦天qintian0303 发表于 2024-9-5 20:41 感觉好复杂啊，不能和阿里云似的直接网页操作吗？  应该可以的，HA里面集成了mqtt docker，自己去设置一下吧，传感器应该也可以自己设置。

bigjiong 发表于 2024-8-30 14:28 想在串口看到波形的话,波特率得调大一些,要不波形会失真. 哦，我会再试一试。

发表了主题帖： 【Follow me第二季第2期】+ 基础任务（DAC,OPAMP,ADC)

A、驱动12x8点阵LED 根据用户教程Using the Arduino UNO R4 WiFi LED Matrix这个说明手册，我们可以知道点阵LED的显示原理，每一个LED代表一位，一共有96个LED，发送一次LED数据至少96位，手册中发送一个frame，内有96个点，例如 unsigned long frame[] = {   0x3184a444,   0x42081100,   0xa0040000 }; 发送数据时需要发送转换后的二进制数值， 0x3184a444（110001100001001010010001000100） 0x42081100（1000010000010000001000100000000） 0xa0040000（10100000000001000000000000000000） 用串口发送二进制方式发送数据， for (int b = 0; b < 3; b++) {     Serial.println(frame, BIN); } 开发板软件包内提供了LED Matrix library，只要包含头文件，定义一个ArduinoLEDMatrix matrix变量，使用matrix的loadFrame函数就可以显示了。如图所示。   [localvideo]5eb9d7e8b42f5d5bd66301714cf41e4e[/localvideo]   B、用DAC生成正弦波 使用sineWave的例子，下载到板子里面运行。   A0输出正弦波形，用示波器显示。 [localvideo]db567f579f3c1530a274d4993e110956[/localvideo]   C、用OPAMP放大DAC信号； 电压放大2倍电路接法如图所示。     这个输入A1是如何显示方波的呢？ [localvideo]9e54f2350de5c5bbbb289b82aff254f9[/localvideo] 不知道我这个测试方法是否正确？ 用ADC采集并且打印数据到串口等其他接口可上传到上位机显示曲线

秦天qintian0303 发表于 2024-8-26 11:26 你这是第一个收到的吧，Arduino IDE编译速度怎么样 不错，这个IDE在我电脑上很快。

发表了主题帖： 【Follow me第二季第2期】+ 搭建环境并开启第一步Blink / 串口打印Hello EEWorld！

找资料 首先搜Arduino UNO R4 WiFi，找到官网入口，点击DOCUMENTATION，找到左侧找到Hardware，点击展开，在Classic找到UNO R4 WiFi，点击里面就是各种资料了，如图1所示。   图1 我们在Tutorials页面里面找到Getting Started with UNO R4 WiFi，如图2所示。   图2 根据步骤看，可以使用Arduino IDE，也可以用Web Editor。 下载IDE，下载比较慢，用迅雷下载较快。   解压后直接使用即可。 安装环境 打开软件，如图所示。   安装开发板软件包，如图所示   安装过程如图所示。   选择开发板，如图所示   串口打印hello EEWorld！   用Type-C数据线连接电脑及开发板，编写个串口初始化及打印，如图所示，下载到板子内，串口打印完成。
