【得捷电子Follow me第3期】任务完成汇总 [复制链接]

  本帖最后由 meiyao 于 2023-11-23 23:37 编辑

任务1：使用MicroPython系统（必做任务）

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

下面进行第一步：

安装Thonny版本是4.14的。

Thonny, Python IDE for beginners

https://thonny.org/

或者直接进仓库下载：

链接已隐藏，如需查看请登录或者注册

 

进入下载连接在最下面就可以看到：

 

安装好后的版本：

再安装BIN文件到ESP32中：

https://micropython.org/download/esp32c3/

 

将ESP32-C3 XIAO的开发板，通过USB转Type-C的线缆，链接到电脑上。运行Tohonny exe，在【运行】->【解析器页面】->选择Micropython （ESP32），然后在端口选择ESP32-C3 XIAO在电脑上虚拟出来的COM口。如下所示：

 

打列软件后，在右下角选择ESP32与对应的端口就说明，环境与板子已成功，表明可以进行下一步了。

 

任务2：驱动扩展板上的OLED屏幕（必做任务）

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

首先第一步就是要安装那个库文件。

 

这里需要注意的是，有点不好装成功，但是要开梯子才可以装成功，而且要4.14的版本，我也是一直安装失败，最后才装成功，我这里是装好的，安装成功后，卸载会显示。

来两个照片：

任务4：连接WiFi网络（必做任务）

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

利用了ESP32的强大的网络功能，将外置天线连接到模块上的IPEX座了。

 

购买的这个天线似乎要好一点。

连接网络成功并正确获取到时间，并在 OLED 上显示当前时间，以1S的时间打印并在OLED上跳动。

核心代码：

# Execute the functions
scan_and_connect()

# 从时间服务器获取时间
ntptime.settime()

while True:
    # 获取当前时间戳，此处加了8小时的时区差
    current_time = utime.time() + 8 * 60 * 60
    print("Current Time:", current_time)

    # 将时间戳转换为本地时间
    local_time_value = utime.localtime(current_time)
    print("Local Time:", local_time_value)
    
    # 根据日期时间转换，便于打印和显示
    local_data = "{:02d}-{:02d}-{:02d}".format(local_time_value[0], local_time_value[1], local_time_value[2])
    local_time = "{:02d}:{:02d}:{:02d}".format(local_time_value[3], local_time_value[4], local_time_value[5])

    print(local_data)
    print(local_time)

    # 更新显示内容
    oled.fill(0)
    oled.text(local_data, 10, 25)
    oled.text(local_time, 10, 40)
    oled.show()  
    
    # 延时1秒
    utime.sleep(1)

任务5：使用外部传感器（必做任务）

 

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

首先看连接方式：

 

温湿度传感器模块 连接至扩展板的 I2C 接口（开关旁边）。将 光传感器模块 连接至扩展板的 A0-D0 接口（蜂鸣器旁边）。

可以先找到ATH20的库文件，上传到开发板中，我是手动添加进去的。

库地址：https://pypi.org/search/?q=aht20

核心代码：

from machine import Pin, SoftI2C, ADC
import ssd1306
import utime
import time
from ahtx0 import AHT20

i2c = SoftI2C(scl=Pin(7), sda=Pin(6))

oled_width = 128
oled_height = 64
oled = ssd1306.SSD1306_I2C(oled_width, oled_height, i2c)

# 清空屏幕，并显示任务要求
oled.fill(0)
oled.text("ESP32 _ C3 fifth", 0, 0)
oled.text("ATH20:", 0, 16)
oled.text("Humi:", 0, 32)
oled.text("Light:", 0, 48)
oled.show()

# aht20
