部分功能需要自行开放,源码完整可编译...一直珍藏的东西..希望大家拿去多多学习-CSA (stone) ... part of the package source feature requires its own open-source can compile a complete collection of things have been ... .. hope that everyone take a lot to learn

说明：  STM32官方固件库,V3.5,基本功能都有(STM32F103 firmware V3.5,all functions can used)

STM32 OLED 驱动单片机PWM波(STM32 OLED driver PWM WAVE WAVE)

基于51单片机制作的函数信号发生器，用DA0832和运算放大器来输出，单片机产生信号，用proteus仿真了（内含），能够产生正弦波，方波，锯齿波，三角波的波形。(51 single-chip microcomputer-based production function signal generator, used to DA0832 and the op-amp output, single-chip signal, proteus simulation with the (implicit), can produce sine, square, sawtooth, triangle wave.)

单片机按键识别，用于实现不同的键盘输入的识别与后续操作。(The single-chip button recognition is used to realize the recognition and subsequent operation of different keyboard inputs.)
