1.1 拷贝源代码
拷贝HARDWARE文件夹里面包括OLED.c/.h和移植好的U8g2csrc文件夹
1.2 将源代码添加到工程
将代码分别添加到工程的User/OLED组和User/U8G2组所有.c文件都添加
1.3 修改代码优化等级
这里添加的好多文件用不到需要把代码优化等级调整到Level 1
1.4 添加头文件路径
..\HARDWARE\oled
..\HARDWARE\U8g2csrc1.5 修改STM32CubeMX工程
只需要添加3个控制引脚SPI和W5500是共用的
2 修改源代码
源代码全部在main.c里面修改
2.1 添加头文件
/* USER CODE BEGIN Includes */
#include string.h
#include stdio.h
#include w5500_spi.h
#include wizchip_conf.h
#include socket.h
#include OLED.h

/* USER CODE END Includes */2.2 main函数修改
局部变量
