IAR for STM8L标准库硬件I2C/SPI驱动SSD1306 OLED屏幕
IAR for STM8L标准库硬件I2C/SPI驱动SSD1306 OLED屏幕
-
参考STM32硬件驱动
https://github.com/lamik/OLED_SSD1306_STM32_HAL -
✨说明，本工程仅验证了硬件I2C接口，硬件SPI接口的SSD1306 OLED屏幕手上没有，并没有验证是否可行。
-
基于IAR开发环境，单片机：
STM8L052R8 -
效果演示：
-
软件驱动方式可以参考屏幕驱动厂家提供的资料修改得来。
- 图形取模方式，可以参考屏幕厂家资料。测试时，我也是直接拷贝的屏幕厂家资料中的取模图片数据粘贴过来的。
注意：不要找我要取模软件（有截图，有名字，自行搜索下载）
硬件接口说明
- 硬件引脚映射关系图：
- 硬件接口软件配置在
hw_setup.h文件中,具体单片机驱动根据具体型号修改相关内容。
