项目介绍
有幸参加了这次得捷Follow me第3期活动。通过这个活动，深入了解了Seeed Studio XIAO ESP32C3开发板及相关组件的使用，涉及了MicroPython、OLED屏幕、蜂鸣器、WiFi网络、外部传感器等多个方面。以下是我在每个任务中的具体实现过程。
任务1：使用MicroPython系统
熟悉Seeed Studio XIAO ESP32C3开发板基本操作，安装esptool，并给开发板刷写MicroPython系统，完成入门程序的运行
搭配器件：Seeed Studio XIAO ESP32C3
硬件准备
使用Seeed Studio XIAO ESP32C3和扩展板作为硬件。
软件准备
1 下载安装 Thonny IDE (Windows
2 下载esptool-win64
3 下载 ESP32_GENERIC_C3-20231005-v1.21.0.bin
烧录固件
按住BOOT按钮，同时按住BOOT按钮，将电路板连接到PC，然后释放它以进入bootloader模式。
然后进入esptool-v4.6.2-win64目录执行烧录命令：
./esptool.exe --chip esp32c3 --port COM18 --baud 921600 --before default_reset --after hard_reset --no-stub write_flash --flash_mode dio --flash_freq 80m 0x0 .\ESP32_GENERIC_C3-20231005-v1.21.0.bin
测试MicroPython状态；
任务2：驱动扩展板上的OLED屏幕
使用扩展板上的OLED屏幕显示文字和图形
搭配器件：Seeed Studio XIAO ESP32C3、Seeed Studio Expansion Board Base for XIAO
安装驱动OLED显示屏需要的ssd1306库
import time
from machine import Pin, SoftI2C
import ssd1306
import math
# ESP8266 Pin assignment
i2c = SoftI2C(scl=Pin(7), sda=Pin(6)) # Adjust the Pin numbers based on your connections
oled_width = 128
oled_height = 64
oled = ssd1306.SSD1306_I2C(oled_width, oled_height, i2c)
oled.fill(0) # Clear the screen
oled.text("FollowMe3 !", 10, 15)
oled.text("/////", 30, 40)
oled.text("(`3`)y", 30, 55)
oled.show() # Show the text
这段代码通过ESP32C3控制SSD1306 OLED显示屏，在屏幕上显示"FollowMe3"等文本信息。它使用SoftI2C进行I2C通信，初始化硬件引脚并清空显示屏，然后在指定位置显示文本，最后更新显示。
import time
from machine import Pin, SoftI2C
import ssd1306
# ESP8266 Pin assignment
i2c = SoftI2C(scl=Pin(7), sda=Pin(6)) # Adjust the Pin numbers based on your connections
oled_width = 128
oled_height = 64
oled = ssd1306.SSD1306_I2C(oled_width, oled_height, i2c)
# Clear the screen
oled.fill(0)
# Square parameters
square_size = 20
center_x = oled_width // 2
center_y = oled_height // 2
# Draw a square in the center of the screen
square_x = center_x - square_size // 2
square_y = center_y - square_size // 2
oled.fill_rect(square_x, square_y, square_size, square_size, 1)
# Update the OLED display
oled.show()
# Wait for a while before exiting
time.sleep(5)
这段代码使用ssd1306库在OLED显示屏中心绘制一个正方形，通过调整参数可以改变正方形的大小。代码首先初始化OLED显示屏，清空屏幕，计算正方形在屏幕中心的位置，然后使用fill_rect方法绘制一个填充的矩形（正方形），最后更新显示并等待5秒后退出。
任务3：控制蜂鸣器播放音乐
使用Seeed Studio XIAO ESP32C3控制蜂鸣器发出不同频率的声音，并播放一段音乐
搭配器件：Seeed Studio XIAO ESP32C3、Seeed Studio Expansion Board Base for XIAO

play_song()
这段代码使用MicroPython的time的machine模块控制ESP32C3开发板上的蜂鸣器（buzzer）播放了一首简单的音乐。通过定义音符和它们的频率，以及每个音符的时长，代码按照指定的音乐谱演奏音乐。音符和时长以列表的形式存储，其中0表示休止符。play_song 函数遍历这些列表，根据当前音符的频率和时长设置蜂鸣器，并在每次演奏后暂停一段时间。
在主循环中，代码持续播放这首音乐。如果想要播放其他曲目或调整音乐的音符和时长，只需修改 notes 和 durations 列表即可。
任务4：连接WiFi网络
将Seeed Studio XIAO ESP32C3连接到WiFi网络，并访问互联网信息
搭配器件：Seeed Studio XIAO ESP32C3、Seeed Studio Expansion Board Base for XIAO、RF ANT 2.4GHZ/5.5GHZ PCB TRACE
时区API查找:
Full list of Timezones, via World Time API: Simple JSON/plain-text API to obtain the current time in, and related data about, a timezone.
在这个任务中，我使用了时区API来获取当前时间和相关时区信息。通过这个经验，我了解了如何通过网络服务获取实时时间，这对于实际项目中的时间同步非常有用。

print("Connected!")
print("My IP Address:", station.ifconfig()[0])
while True:
# Perform HTTP GET request on a non-SSL web
response = urequests.get(url)
# Check if the request was successful
if response.status_code == 200:
# Parse the JSON response
data = ujson.loads(response.text)
# Extract the "datetime" field for New York
ny_datetime = data["datetime"]
# Split the date and time components
date_part, time_part = ny_datetime.split("T")
# Get only the first two decimal places of the time
time_part = time_part[:8]
# Get the timezone
timezone = data["timezone"]
# Clear the OLED display
oled.fill(0)
# Display the New York date and time on separate lines
oled.text("Shanghai Date:", 0, 0)
oled.text(date_part, 0, 10)
oled.text("Shanghai Time:", 0, 20)
oled.text(time_part, 0, 30)
oled.text("Timezone:", 0, 40)
oled.text(timezone, 0, 50)
# Update the display
oled.show()
else:
oled.text("Failed to get the time for New York!")
# Update the display
oled.show()
这段代码连接到Wi-Fi网络后，向在线API发出HTTP GET请求以获取上海的当前日期和时间信息，然后将这些信息显示在SSD1306 OLED的屏幕上。代码首先扫描可用的Wi-Fi网络，尝试连接到指定的网络。一旦连接成功，它会持续地从在线API获取上海的日期、时间和时区信息，并将这些信息显示在OLED屏幕上。
任务5：使用外部传感器
连接环境光传感器或温湿度传感器，获取传感器的数值，并转换成真实的物理量
搭配器件： Seeed Studio XIAO ESP32C3、Seeed Studio Expansion Board Base for XIAO、 Grove - AHT20 I2C Industrial Grade Temperature and Humidity Sensor、Grove - Light Sensor v1.2
该任务实现是通过Arudion平台实现的

const int sensorPin = A0;
void setup(void) {
u8x8.begin();
u8x8.setFlipMode(0); // set number from 1 to 3, the screen word will rotary 180
pinMode(sensorPin, INPUT); // declare the sensorPin as an INPUT
AHT.begin();
Serial.begin(115200);
while (!Serial);
}
const char *convert_FPS(uint16_t fps) {
static char buf[6];
strcpy(buf, u8g2_u8toa( (uint8_t)(fps), 3));
buf[3] = '.';
buf[4] = (fps % 10) + '0';
buf[5] = '\0';
return buf;

void loop(void) {
float humi, temp;
int ret = AHT.getSensor(&humi, &temp);
// read the value from the sensor:
int light = analogRead(sensorPin);
if(ret) // GET DATA OK
{
Serial.print("humidity: ");
Serial.print(humi*100);
Serial.print("%\t temerature: ");
Serial.print(temp);
Serial.print("%\t light: ");
Serial.println(light);
}

u8x8.setCursor(0, 0);
u8x8.printf("%.2f %.2f %d", temp,humi*100, (uint8_t)light);
// delay(1000);
}
这段Arduino代码使用AHT20传感器读取环境温湿度，同时通过Light传感器获取环境光强度，并将这些数据显示在连接的SSD1306 OLED屏幕上。代码还通过串口输出将温湿度和光照度数据发送到串口监视器。
任务6：XIAO-PWM任意音乐播放器
在前几个任务中，已经成功体验了Seeed Studio XIAO ESP32C3的基本操作，包括MicroPython系统的刷写、OLED屏幕的驱动、蜂鸣器的控制等。最后一项任务是任务3的基础之上进一步实现任意音乐的播放。为了简化音乐代码的添加，使用MuseScore 3软件MID文件进行初步转换，最终通过转换工具自动生成相应的音乐代码。
1. 使用软件和准备工作
使用了以下软件：
2. 获取音乐对应的MID文件
首先，我们需要获得音乐的MID文件。你可以直接下载MID格式音乐文件，或者将某段音乐转换为MID文件。在这个例子中，我们使用现成的MIDI文件。如果需要将其他格式音乐转换为MID格式，可以参考网络上的相关教程。
3. 将MID文件转为MUSICXML文件
MusicXML 是一种用于表示音乐符号、音符、和其他与音乐相关的信息的 XML 文件格式。
打开 MuseScore 3，将MID文件拖拽或添加进软件。然后点击“文件”→“导出”，设置输出文件为musicxml格式。
4. 提取MUSICXML文件关键字，自动生成音乐代码
接下来，我们使用 C 语言编写代码，用于提取musicxml文件中的音符信息。以下是代码的主要结构：
#include <stdio.h>
#include <stdlib.h>
#include <string.h>
int convertCharToInt(char x);
void parseMusicXML(const char* filename);
int main() {
char filename[] = "china.musicxml";
parseMusicXML(filename);
return 0;
}
void parseMusicXML(const char* filename) {
FILE* filePointer;
char musicSymbol[11] = {0};
int noteCount = 0;
int errorCount = 0;
int flag = 0;
int beatsPerMeasure = 0;
int printCounter = 0;
int divisions = 1;
int noteDuration = 1;
int currentPosition = 0;
filePointer = fopen(filename, "r");
if (filePointer == NULL) {
printf("Failed to open file\n");
return;
}
printf("Number of beats per measure: ");
scanf("%d", &beatsPerMeasure);
printf("Number of beats per measure: %d ", beatsPerMeasure);
for (int i = 0;; i++) {
fseek(filePointer, i, SEEK_SET);
musicSymbol[0] = fgetc(filePointer);
if (musicSymbol[0] == EOF)
break;
for (int j = 1; j < 11; j++) {
fseek(filePointer, i + j, SEEK_SET);
musicSymbol[j] = fgetc(filePointer);
if (musicSymbol[j] == EOF)
break;
}
if (musicSymbol[0] == '<' && strncmp(&musicSymbol[1], "divisions>", 10) == 0) {
for (int j = 0;; j++) {
fseek(filePointer, i + 11 + j, SEEK_SET);
if (fgetc(filePointer) == '<')
break;
else {
if (j == 0) {
fseek(filePointer, i + 11 + j, SEEK_SET);
divisions = convertCharToInt(fgetc(filePointer));
} else {
fseek(filePointer, i + 11 + j, SEEK_SET);
divisions = 10 * divisions + convertCharToInt(fgetc(filePointer));
}
}
}
printf("%d,", divisions);
break;
}
}
while (!feof(filePointer)) {
fseek(filePointer, currentPosition, SEEK_SET);
musicSymbol[0] = fgetc(filePointer);
if (musicSymbol[0] == EOF)
break;
for (int i = 1; i < 11; i++) {
fseek(filePointer, currentPosition + i, SEEK_SET);
musicSymbol[i] = fgetc(filePointer);
if (musicSymbol[i] == EOF)
break;
}
if (musicSymbol[0] == '<' && strncmp(&musicSymbol[1], "step>", 5) == 0) {
fseek(filePointer, currentPosition + 6, SEEK_SET);
char step = fgetc(filePointer);
fseek(filePointer, currentPosition + 32, SEEK_SET);
char nextChar = fgetc(filePointer);
if (nextChar == '>') {
fseek(filePointer, currentPosition + 33, SEEK_SET);
nextChar = fgetc(filePointer);
for (int i = 0; !feof(filePointer); i++) {
fseek(filePointer, currentPosition + 81 + i, SEEK_SET);
char c = fgetc(filePointer);
if (c == '<')
break;
else {
if (i == 0)
noteDuration = convertCharToInt(c);
else
noteDuration = 10 * noteDuration + convertCharToInt(c);
}
}
} else {
fseek(filePointer, currentPosition + 61, SEEK_SET);
nextChar = fgetc(filePointer);
if (nextChar == '<') {
fseek(filePointer, currentPosition + 60, SEEK_SET);
nextChar = fgetc(filePointer);
}
for (int i = 0; !feof(filePointer); i++) {
fseek(filePointer, currentPosition + 109 + i, SEEK_SET);
char c = fgetc(filePointer);
if (c == '<')
break;
else {
if (i == 0)
noteDuration = convertCharToInt(c);
else
noteDuration = 10 * noteDuration + convertCharToInt(c);
}
}
}
if (flag == 0) {
printf("%d,", beatsPerMeasure);
flag++;
printf("\n");
}
if (step < 'A' || step > 'G')
errorCount++;
if (nextChar < '0' || nextChar > '9')
errorCount++;
printf("NOTE_%c%c,%d,", step, nextChar, noteDuration);
noteCount++;
printCounter++;
if (printCounter == 3) {
printf("\n");
printCounter = 0;
}
}
currentPosition++;
}
fclose(filePointer);
printf("0\n");
printf("Parse Done %d, Error num: %d\n", noteCount, errorCount);
system("pause");
}
int convertCharToInt(char x) {
if (x >= '0' && x <= '9')
return x - '0';
return -1;
}
这段C代码实现了解析MusicXML文件的功能。首先，用户输入小节的拍号信息，然后通过遍历文件找到 <divisions> 标签，提取每小节的拍号。接着，循环遍历文件，查找 <step> 标签，提取音符、音符时值等信息，并输出解析结果。
5. 手动生成音乐代码
将上一步获取到的musicxml格式文件的路径添加到代码中，手动输入每分钟节拍数，运行控制台即可生成音乐代码。将生成的代码复制并粘贴到我们之前任务中的 music[] 数组中。
