[开源]STM32F103RCT6移植u8g2 ＞ 硬件i2c ＞ WouoUI移植
- 🔖使用LL库和STD标准库的可以参照上面的例程测试。这里不多种说明。
✅功能部分说明
- 🌿显示部分：U8g2库驱动
- 🌿按键：采用Multi-button库驱动
- 🎞SH1106驱动显示效果：
- 📺I2C SSD1306 0.96"屏幕显示效果：
HAL库程序是基于上面的LL库移植过来的，采用的是STM32F103VET6。保留了按键控制功能，去掉了其他没有的外设。
-
🔖AC6编译器，优化等级默认
Level 1 (o1)。
-
🔖AC5编译器，优化等级至少要设置
Level 1 (o1),否则会报L6406E错误。

🔨HAL库程序SSD1306/sh1106屏幕选择与代码调整
- ✨在oled.c中，OLED初始化
OLED_Init(void)函数。（sh1106屏幕刷SSD1306程序也可以显示，只是边框有一部分是马赛克雪花）
//***************************** 使用下面2个
u8g2_Setup_sh1106_i2c_128x64_noname_f(&u8g2, U8G2_R0, u8x8_byte_hw_i2c, stm32_gpio_and_delay); //1.3" sh1106 使用这个

🌼U8g2库移植说明
- 🌿可以借用上面的LL库的工程，直接拷贝对应的驱动文件夹到自己所创建的工程目录下。
- 🌿其他屏幕型号，需要提前准备一个能驱动显示的工程作为模板。
- 🌿将以下3个核心函数，拷贝到能显示的模板工程中，根据驱动屏幕型号进行调整：
