【蓝桥杯嵌入式】LCD屏的原理图解析与代码实现（第十三届省赛为例）——STM32

目录原理图解析设置STM32CubeMX配置文件测试LCD屏函数实例运用正文原理图解析观察LCD的原理图，LCD的引脚比较多，在下一个步骤设置STM32CubeMX时，最好一一对应地去设置，以免缺漏。但需要注意的是，在官方文件的实例代码中，已有LCD.c与.h文件，我们可以直接移动到我们的工程文件即可设置STM32CubeMX对照原理图将各个引脚设置好即可配置文件这一步与上一步选择一个便可。推....

【蓝桥杯嵌入式】点亮LED灯，流水灯的原理图解析与代码实现——STM32

目录看原理图设置STM32CubeMX配置文件初始化LED函数实例运用正文看原理图可以看到控制LED灯的是PC8～PC15，由于图中最左边是VDD，也就是高电平控制的，所以当PC8～PC15为高电平的时候，LED亮，为低电平的时候，LED灭。同理PD2低电平关，高电平开设置STM32CubeMX打开我们已经建立好的工程（如何初始化STM32工程）中的STM32CubeMX将PC8~PC15和PD....
