刚才测试了STM32F030普通端口的电压电流的关系。可以看到它不是5V容忍的输入端口。随着电压超过3.7V，开始有了比较大的倒灌电流。下面测试一个 STM32F103中 5V 容忍IO端口的伏安特性。 二、测量结果 制作电路板。焊接之后，进行测试。给电路板下载简单 ...

键盘使用模块化设计，左侧的多功能场景交互模块可以替换成各种自定义组件，默认使用的是一个带电子墨水屏以及FOC力反馈旋钮的Dynamic组件；键盘使用我自己开发的基于ARM Cortex-M芯片的键盘固件以及模块固件；键盘本体使用移位寄存器方式实现优化的按键扫描 ...

ws2812做为RGB灯，在很多场合都是非常有用的，我准备使用STM32H755的M4内核驱动时，遇到了一些问题，因此先用STM32F103来验证一下，找到库存的STM32103的开发板，来实现驱动，特记录如下： 2.打开外部时钟，因为内部时钟最高只能跑到64MHz。 3.在时钟配置界面，配置 ...
