|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
## 一、安装 USB 驱动
|
|
|
|
|
|
|
|
|
|
|
|
点击以下链接，下载 M5Stack-Core 的 USB 转串口驱动
|
|
|
|
|
|
|
|
|
|
|
|
https://www.silabs.com/products/development-tools/software/usb-to-uart-bridge-vcp-drivers
|
|
|
|
|
|
|
|
|
|
|
|
下载完之后，解压，根据系统位数，双击对应可执行文件
|
|
|
|
|
|
|
|
|
|
|
|
(Windows 32位，执行 CP210xVCPInstaller_x68.exe；Windows 64位，执行 CP210xVCPInstaller_x64.exe；)
|
|
|
|
|
|
|
|
|
|
|
|
*判断驱动安装是否成功：*
|
|
|
|
|
|
如果安装成功，在插入 M5Stack 主控之后，设备管理器如下图所示出现，Silicon Labs 的 CP21x 系列串口端口号
|
|
|
|
|
|
(我的电脑当前串口号是 COM3)
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
## 二、开发环境
|
|
|
|
|
|
## **Windows**
|
|
|
|
|
|
### 1、安装 Arduino IDE
|
|
|
|
|
|
|
|
|
|
|
|
*下载地址*
|
|
|
|
|
|
https://www.arduino.cc/en/Main/Software
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
如下图所示修改 Arduino 路径为 D:\Program Files
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
此时，Arduino 的安装路径为 D:\Program Files\Arduino
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
### 2、下载 ESP32 相关支持包
|
|
|
|
|
|
|
|
|
|
|
|
（我的 Arduino 当前路径是 D:\Program Files\arduino）
|
|
|
|
|
|
|
|
|
|
|
|
进入 Arduino 安装路径的 hareware 文件夹，按住 Shift 键的同时，右键选择“在此处打开命令窗口”
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
在打开的 Windows 终端 CMD 中输入如下命令
|
|
|
|
|
|
|
|
|
|
|
|
> * 创建 espressif 目录，并切换到此目录下
|
|
|
|
|
|
|
|
|
|
|
|
mkdir espressif && cd espressif
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
> * 将 esp32 idf clone 在文件夹 esp32 下
|
|
|
|
|
|
|
|
|
|
|
|
git clone --recursive https://github.com/espressif/arduino-esp32.git esp32
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
### 3、下载 ESP32 编译链 tools
|
|
|
|
|
|
|
|
|
|
|
|
进入此路径 D:\Program Files\arduino\hardware\espressif\esp32\tools
|
|
|
|
|
|
选中并双击执行 get.exe 文件
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
### 4、Arduino IDE 中下载 M5Stack 的库
|
|
|
|
|
|
|
|
|
|
|
|
打开 Arduino IDE 之后，选择“项目”->“加载库”->“管理库...”，搜索“M5Stack”并点击“安装”
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
## 三、示例
|
|
|
|
|
|
|
|
|
|
|
|
USB 线连接 M5Stack 主控，选择串口和一个示例程序，compile and upload
|
|
|
|
|
|
|
|
|
|
|
|
### 1、打开一个示例程序，如打开 FactoryTest.ino
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
确认连接板子名称、串口波特率和当前串口号分别：M5Stack-Core-ESP32、921600、COM3(当前电脑串口号)
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
编译运行成功之后，串口监视窗口显示如下
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
### 2、新建一个 M5Stack 程序
|
|
|
|
|
|
|
|
|
|
|
|
打开 Arduino IDE 之后，新建 .ino 文件，并保存为 my_test.ino
|
|
|
|
|
|
|
|
|
|
|
|
将如下代码拷贝进文件中。
|
|
|
|
|
|
|
|
|
|
|
|
```cpp
|
|
|
|
|
|
#include <M5Stack.h>
|
|
|
|
|
|
|
|
|
|
|
|
// the setup routine runs once when M5Stack starts up
|
2018-06-20 10:11:54 +08:00
|
|
|
|
void setup(){
|
2018-06-15 10:32:25 +08:00
|
|
|
|
|
|
|
|
|
|
// Initialize the M5Stack object
|
|
|
|
|
|
M5.begin();
|
|
|
|
|
|
|
|
|
|
|
|
// LCD display
|
|
|
|
|
|
M5.Lcd.print("Hello World!");
|
|
|
|
|
|
M5.Lcd.print("M5Stack is running successfully!");
|
|
|
|
|
|
}
|
|
|
|
|
|
|
|
|
|
|
|
// the loop routine runs over and over again forever
|
|
|
|
|
|
void loop() {
|
|
|
|
|
|
|
|
|
|
|
|
}
|
|
|
|
|
|
```
|
|
|
|
|
|
|
|
|
|
|
|
点击编译运行，此时 M5Stack 显示器显示 "Hello World!" "M5Stack is running successfully!"
|
|
|
|
|
|
|
|
|
|
|
|
|
