-## 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。

-## **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)
-```
-
-### lcd.setColor(color [,bcolor])
-设置默认的绘画颜色和背景色,bcolor一般用于设置文字显示的背景色。
-
-
-### lcd.print(text, [x, y, color])
-
-显示字符串 *text* 在 *(x, y)* 指定的位置,参数 *color* 为颜色参数。
-
-(注:在中括号如[x, y, color]内的表示为可选参数)
-
-* **x**: 指定水平方向的位置显示, 有以下特殊参数:
- * LASTX(默认), 直接上一个光标的文字接着显示
- * CENTER, 居中显示文本
- * RIGHT, 右对齐文本
-
-* **y**: 指定垂直方向的位置显示, 有以下特殊参数:
- * LASTX(默认), 直接上一个光标的文字接着显示
- * CENTER, 居中显示文本
- * BOTTOM, 文字靠底部显示
-
-* **color**:如果该参数未设置,默认为 *lcd.setColor* 设置的颜色。
-
-
-
-### lcd.println(text, [x, y, color])
-
-lcd.println函数功能与 *lcd.print* 函数功能基本一样,只是会在最后自动换行。
-
-```python
-lcd.print('hello world\n')
-lcd.println('hello world') #显示效果一致
-```
-
-
-### lcd.font(font)
-
-设置字体.
-
-可以使用内置的字体已定义好的参数:
-
-**FONT_Default, FONT_DefaultSmall, FONT_DejaVu18, FONT_Dejavu24, FONT_Ubuntu, FONT_Comic, FONT_Minya, FONT_Tooney, FONT_Small, FONT_7seg**
-
-```python
-lcd.font(lcd.FONT_Dejavu24) #设置为FONT_Dejavu24字体
-```
-
-### lcd.textWidth(text)
-
-返回字符串 *text* 字体显示占用的宽度。
-
-
-### lcd.fontSize()
-
-返回当前字体的 *width* 和 *heigh*。
-
-
-Example:
-
-```python
-from m5stack import lcd
-
- #在屏幕上hello world
-lcd.print('hello world')
-
-#在屏幕x=10,y=100的地方显示hello world
-lcd.print('hello world', 10, 100)
-
-#显示的文字颜色为绿色的hello world
-lcd.print('hello wrold', color=0xFF0000)
-
-#在屏幕x=10,y=100的地方显示红色的hello world字体
-lcd.print('hello world', 10, 200, 0xFF0000)
