　设计了一种以PIC16F877单片机作为控制核心的录放音智能语音系统, 采用ISD4003 - 8M设计制作了具有定时录音、 放音的语音提示器, 可以真实的再现语音的真实自然效果, 避免了一般语音电路因为量化和压缩所造成的量化噪声和失真。该系统 操作简单, 可靠性高, 成本低, 可广泛用于各种对安放要求较高的场合。(Design a single chip microcomputer as the core to control the PIC16F877 recording sound intelligent voice system, adopting ISD4003-8 M design a timing recording, Let the sound of speech cuing component, can be true of representation of the true nature of speech effect, to avoid the general voice circuits for quantitative and compressed by the quantization noise and distortion. The system Simple operation, high reliability, low cost, can be widely used in all kinds of higher requirements to put the occasion. )

电力规约代码101协议代码，经过大量现场运行验证，与国内外各大公司产品进行过互操作实验。(101 Source protocol)

使用STM32F4+usb3300实现虚拟示波器,支持使用外部ADC模式，也就是使用AD9280芯片，最大采样率可达30MSPS.(STM32F4+usb3300 implementation of the virtual oscilloscope, support the use of external ADC mode, that is, the use of AD9280 chip, the maximum sampling rate of up to 30MSPS )

51单片机 128*64 oled显示屏驱动程序 驱动芯片 ssd1309，并口或spi总线驱动 (51 microcontroller 128* 64 oled display driver Driver chip ssd1309, parallel or spi bus driver)

说明：  LLC电路的PI闭环程序，实现电流闭环，非常稳定经过实测，没有问题(The PI closed-loop program of LLC circuit realizes the current closed-loop, which is very stable. After actual measurement, there is no problem)

一个用C语言控制的读写7022，存储数据，485上传数据，向液晶模块显示数据的程序。此程序为测试程序，所有与模块通讯功能都能实现。(A use of C language to read and write control 7022, data storage, 485 From the data, display data to the LCD module procedures. This procedure for testing procedure, all communication functions and modules can achieve.)
