基于音频芯片声音模块数模输出资料V1.2

电子秤proteus仿真，有压力传感器和AD转换模块(Electronic Liureus simulation with pressure sensor and AD conversion module)

说明：  这是msp exp430f5529的原理图(This is the schematic diagram of MSP exp430f5529)

说明：  单片机上电以后LCD屏上显示欢迎回家， 先验证指纹再验证密码 ，同时验证成功开锁 指纹和密码分别可以验证3次 3次都错蜂鸣器响 ，按下manage键进入管理员模式 可以修改密码 删减指纹，指纹用开关量表示(After the microcontroller is powered on, the LCD screen shows welcome home. First verify the fingerprint and then verify the password. At the same time, verify the successful unlocking fingerprint and password can verify that the buzzer rings three times and three times respectively. Press the management key to enter the administrator mode to modify the password and delete the fingerprint. The fingerprint is expressed by the switch.)

说明：  MAX31856测试程序，MSP430F5342通过端口模拟SPI总线操作MAX31856,并将采集到的数据通过UCA1串口发送.硬件上采用隔离电源,隔离通讯接口.多路热电偶信号经多路电子开关选通后再采集.仅供参考,实验室调试通过,未投入实用. 压缩包内容: 1.MSP430程序源代码.包括测试程序及加了协议的多路采集程序. 2.硬件电路图.PDF格式,包括电路板原理图,PCB布局图,元件清单. 3.MAX31856芯片手册及官方例程. 4.PC端程序(通讯协议仿的迅威科技8通道热电偶温度变送器的协议,所以他们的PC端测试程序应该也是可用的) 整理时间:2020年4月15日(MAX31856 test procedure, MSP430F5342 simulates the SPI bus to operate the MAX31856 through the port, and converts the collected data to serial transmission through UCA1. The hardware uses isolated power supply and isolated communication interface. Reform reference, laboratory debugging passed, not occupied practical. Compressed package content: 1. MSP430 program source code. Including test procedures and multi-channel acquisition procedures with added protocols. 2. Hardware circuit diagram. PDF format, including circuit board schematic diagram, PCB layout diagram, component list. 3. MAX31856 chip manual and official routines. 4. PC-side program (the communication protocol is a copy of the Xunwei Technology 8-channel thermocouple temperature threshold protocol, so their PC-side test program should also be available) Arrangement time: April 15, 2020)

本例程是基于1602液晶显示实时时钟，使用DS1302，使用51系列单片机，通过本例程可以熟悉1602和1302的操作，适合单片机课程设计或者毕业设计的一项功能，程序编译通过可直接移植使用(This routine is based on the 1602 LCD real-time clock, use the DS1302, use 51 series, through this routine may be familiar with the operation of 1602 and 1302, for SCM curriculum design or a functional design Graduation, a program compiled through direct transplantation use)

用于车载充电机DCDC的先进控制，包含PID控制器以及PWM控制H桥输出。(This is used for controling OBC in vehicle DCDC charging mathine, including PID control and PWM controling the output of H bridge)

实时时钟芯片ds1302驱动程序，并配合8位数码管显示。(Real-time clock chip ds1302 driver, and with the 8-bit digital tube display.)

AVR例程，主要涉及液晶屏幕以及通讯，触摸等等。(AVR Sample program。)

说明：  仿照唱吧的UI项目，仅仅是实现了布局方面的一些东西，没有实现实际的功能。(Modeled on the UI project, just to achieve some aspects of the layout, did not achieve the actual function. )

LCD屏的源程序,显示LCD屏,字库需要自己加入(Source LCD screens, LCD display screen,)
