U8g2代码下载：
https://github.com/olikraus/u8g2
1，准备一个正常运行的KEIL5 MDK模板
2，下载u8g2的源码和 u8g2的STM32实例模板
源码: https://github.com/olikraus/u8g2
STM32实例模板: https://github.com/nikola-v/u8g2_template_stm32f103c8t63，去掉无用的驱动文件,只保留u8x8_d_ssd1306_128x64_noname.c
4，精简u8g2_d_setup.c，只保留u8g2_Setup_ssd1306_i2c_128x64_noname_f()5，精简u8g2_d_memory.c,只保留u8g2_m_16_8_f()
6，对工程进行设置并剔除编译错误
7，更改u8x8_gpio_and_delay()
1.在csrc文件中，保留驱动文件u8x8_d_ssd1306_128*64_noname_f
2.将这些文件，放到keil中
在main.c中包含头文件:
#include "u8g2.h" 并包含路径
3.移植好OLED的驱动
4.精简u8g2_d_setup.c，只保留u8g2_Setup_ssd1306_i2c_128x64_noname_f()
5.精简u8g2_d_memory.c,只保留u8g2_m_16_8_f()
6，对工程进行设置并剔除编译错误
7，更改u8x8_gpio_and_delay()
