STM8S系列单单片机教程，第三课，教你从零开始学会使用蜂鸣器，让蜂鸣器唱歌吧(STM8S series single chip tutorial, the third lesson, teach you from scratch to learn to use the buzzer beeper to sing)

将每2片74595做级联，然后再将级联之后的所有时钟线与数据再并联在一起最后对每一组的锁存控制线做单独控制.(Application to do a project, the more I/O, applied to the 74,595 to do the extension, but you want to mount multi-chip 74595, is bound to have a lot to use the I/O port, in order to solve this problem, I will be every 2 sheet 74595 do cascade, and then cascade after all the clock line and the data in parallel and then together (i.e., all 74595 communal clock and data lines, it only occupies two I/O port lines) Finally, for each group latch control lines do individually controlled (equivalent to Chip Select), so that a hardware circuit by a great degree of simplification, both procedures can also share a driving subroutine 74595, to control the type of lock inventory control line, serial data is sent to the port 74595 cascade module. As a result of the hardware and software have a large degree of optimization.)

实现了信号发生功能，输出波形完美，频率。幅值 可调(The function of the signal is realized and the output waveform is perfect.)

这是自己用正点原子探索者写的好盈电调的驱动，有注释，接上线即可用(This is a self - timer atom Explorer written in the "good" power adjustment drive, annotated, connected to the line that is available)

使用SPI接口读写EEPROM器件W25X16系统主时钟为12M，波特率为4M(Using the SPI interface to read and write EEPROM, main clock W25X16 system 12M, the baud rate is 4M)

买的一块开发板的开发文档、原理图还有PCB板，并且附有PCI9054的驱动程序及上位机测试应用程序，调试时需要安装Windriver。(Development board to buy a piece of the development of documents, there are PCB board schematics, and with the PCI9054 PC drivers and test applications, when the need to install debug Windriver.)

这是一个基于STM32F103ZET6的信号发生器的UI设计。本UI包括主菜单，主菜单包括三种波形的选择按键，频率，幅度调节子菜单，FM,AM调制设置子菜单。每个子菜单都有返回主菜单的选项。在任何一个界面中都有当前输出信号频率幅度显示。(This is a signal generator STM32F103ZET6 based UI design. The UI includes a main menu, the main menu includes three waveform selection button, the frequency, amplitude adjustment submenu, FM, AM modulation settings submenu. Each sub-menu has the option to return the main menu. Has a current amplitude of the output signal frequency is displayed on any one screen.)

内含C文件及Proteus仿真文件 矩阵键盘输入密码，初始密码为12345678,每按一次键有短滴声,输入密码正确液晶屏显示正确信息并且电机转动，输入密码错误会发出警报，LED灯闪烁，复位取消警报，0--9号键为数字键,10号键为确认键，11号键清除键清除所输入密码或取消修改密码，12、13、14号键实现修改密码功能。(Containing C file and Proteus simulation file Matrix keyboard input password, the initial password is 12345678, every time a key is pressed, there is a short sound, the correct input password LCD screen displays the correct information and the motor rotates, the input password error will send an alarm, LED flashes, reset and cancel the alarm, 0-9 keys for the digital key, 10 keys for the confirmation key, 11 keys to clear the input secret. Code or cancel password modification, key 12, 13, 14 to achieve password modification function.)

stm32的ad9912的寄存器配置例程，频率，相位，功率的配置。(Stm32 ad9912 register configuration routine, frequency, phase, power configuration.)

TLC5615 D/A转换，用keil C51 编写(TLC5615 D/A conversion with keil C51 prepared)
