|
||||
|
||||
## 快速开始
|
||||
|
||||
### 1. 烧录固件
|
||||
|
||||
#### MacOS/Linux烧录
|
||||
- 使用pip安装esptool：
|
||||
|
||||
```pip install esptool```
|
||||
- 先擦除:
|
||||
``` esptool.py --chip esp32 --port /dev/tty.SLAB_USBtoUART erase_flash ```
|
||||
- 烧录bin文件:
|
||||
``` esptool.py --chip esp32 --port /dev/tty.SLAB_USBtoUART write_flash -z 0x1000 firmware.bin ```
|
||||
|
||||
|
||||
#### Windows烧录
|
||||
Windows使用Espressif提供Flash Download Tools工具烧录([点击下载](http://espressif.com/sites/default/files/tools/flash_download_tools_v3.6.2.2_0.rar))，设置如下(先擦除再烧录)：
|
||||
|
||||
|
||||
|
||||
### 2. 让设备WiFi接入网络
|
||||
- **方法1:** 使用热点接入，通过Web配置网络
|
||||
- 手机或电脑连接M5Stack Core屏幕提示的WiFi热点
|
||||
|
||||
|
||||
连接M5Stack Core WiFi：
|
||||
|
||||
|
||||
- 打开浏览器登陆 192.168.4.1填入WiFi的SSID和密码
|
||||
|
||||
|
||||
- **方法2:** 通过串口配置WiFi密码
|
||||
|
||||
通过串口REPL或者上传工具在设备根目录下创建一个名字为：config.json的文件，文件内wifi的配置参数JSON格式如下：
|
||||
```
|
||||
{
|
||||
"wifi":{
|
||||
"ssid":"MasterHax_2.4G",
|
||||
"password":"12345678"
|
||||
}
|
||||
}
|
||||
```
|
||||
- **方法3:** 通过微信扫描二维码Airkiss接入
|
||||
|
||||
TODO
|
||||
|
||||
### 3. 绑定设备
|
||||
登陆 http://io.m5cloud.com 注册账号,添加设备：
|
||||
|
||||
|
||||
|
||||
将M5Stack Core屏幕显示的Check Code填入绑定设备，Check Code是一次性随机的，60秒会刷新一次，仅仅用于设备绑定验证。
|
||||
|
||||
|
||||
|
||||

Micropython 快速入门
|
||||
|
||||
## **LCD**
|
||||
|
||||
---
|
||||
|
||||
在使用LCD前，先导入LCD对象:
|
||||
|
||||
```python
|
||||
from m5stack import lcd
|
||||
lcd.print('hello world!')
|
||||
```
|
||||
|
||||
也可以直接这样：
|
||||
|
||||
```python
|
||||
import m5stack
|
||||
m5stack.lcd.print('hello world!')
|
||||
```
|
||||
|
||||
或者这样：
|
||||
|
||||
```python
|
||||
import m5stack
|
||||
lcd = m5stack.lcd
|
||||
lcd.print('hello world!')
|
||||
```
|
||||
|
||||
|
||||
#### 颜色
|
||||
|
||||
LCD的 **Color** 颜色使用**24bit**整数类型表示,RGB对应各8bit。
|
||||
|
||||
比如: **0xFF0000** 相当于于完全红色，**0x00FF00** 相当于原谅色绿色。
|
||||
|
||||
常用的颜色可以直接用定义到的参数:
|
||||
|
||||
**BLACK, NAVY, DARKGREEN, DARKCYAN, MAROON, PURPLE, OLIVE, LIGHTGREY, DARKGREY, BLUE, GREEN, CYAN, RED, MAGENTA, YELLOW, WHITE, ORANGE, GREENYELLOW, PINK**
|
||||
|
||||
比如想在LCD打印一句绿色的hello world可以这样：
|
||||
```python
|
||||
lcd.print('hello world', color=lcd.GREEN)
|
||||
```
|
||||
|
||||
也可以这样：
|
||||
```python
|
||||
lcd.print('hello world', color=0X00FF00)
|
||||
```
|
||||
