使用ESP8266驱动微雪e-paer墨水屏
前些时候使用Arduino nona小板子，成功驱动了微雪e-paer2.13墨水屏，但由于Arduino nona小板子内存小、主频低，虽然可以显示，但显示的内容受到限制，心感不爽，一直想把它移植到，STM32或ESP8266这样的32位新片上，现手上有STM32F103C8T6、ESP8266这种低档小板子，没办法，毕竟咱不是专用的，只能有什么用什么了，开干。
1、选择：STM32、ESP8266中选后者吧，有4M闪存，可以放图形或字库。
2、接线：接线是比较麻烦的，初学者往往都是从看别人程序开始的，如果程序不是自己写的（甚至看程序也是半懂不懂），就不知道管脚定义，无法连接，网上那些大咖往往不顾及初学小弟的苦，不屑写明，我这里给小弟。
功能引脚 ESP8266 描述
VCC VCC 电源正(3.3V电源输入)
GND GND 电源地
SCK 14 SPI的CLK， 时钟信号输入
DIN 13 SPI的MOSI， 数据输入
CS 15 片选，低电平有效
BUSY 5 忙状态输出引脚（表示忙碌）
RST 2 复位，低电平有效
DC 4 数据/命令，低表示命令高表示数据
还看不懂下面有实物照片，查线头吧。
3、下程序：程序就不写了，下微雪示例，很标准，编译无错误。
4、学习改造：程序能跑起来后，自己琢磨，改成什么自己看着办吧。

你好，我在微雪官网没有找到Arduino对应这样的例程，可以方便邮箱发我一份吗
