ADS1298 TI MSP430例程，有需要的可以看看(ads1298 driver example, may be very useful)

upd78F9189单片机空调摇控器的原程序，调试通过(upd78F9189 SCM original remote control air-conditioning procedures, debugging through)

寻迹小车程序，用51单片机实现，用红外检测黑线，L298N控制电机(car)

说明：  此代码为stm32将外部flash如w25q32模拟成U盘，对内部数据进行读写操作，此工程已经验证通过，希望对大家用一定的帮助(This code is stm32, which simulates external flash such as w25q32 into a U disk to read and write internal data. This project has been verified and passed. I hope it will be of some help to you)

C++源码实现WAV文件的ADPCM编码和解码(C++ source to achieve a WAV file ADPCM encoding and decoding)

说明：  通过单片机来控制水的温度。 通过设定预定温度，让单片机来自动调动开关，控制水温。(Through the single-chip microcomputer to control the temperature of the water. By setting the target temperature, so that the mobilization of single-chip automatically switches to control the water temperature.)

DALI智能照明系统实现的主要功能是用户可通过智能手机或电脑等，以无线或有线的方式对房内的所有灯光进行单独或者组合控制。主控单元负责协议转换，并且需要记住最近或者常用的场景控制状态，实时地控制每一个从节点。DALI主机可以查找所有的DALI下位机位置并分配相应地址和进行相应控制。 主要功能如下： 1）以安卓智能手机为操作平台对灯具进行单灯控制或分场景进行控制； 2）以平板或PC为操作工具，对系统内的所有灯具进行场景编辑； 3）通过软件对系统内的灯具地址进行自动分配； 4）支持数据的实时存储及掉电存储功能； 5）支持主控器与PC之间的一键上传及下载功能； 6）支持一个系统多个主机； 7）通过家庭路由可实现WIFI全覆盖功能； 8）可通过控制面板对灯具进行控制，同时控制面板的控制指令可编辑。 (The main function of the DALI intelligent lighting system is that the user can control all the lights in the room in a wireless or wired way through a smart phone or a computer. The main control unit is responsible for protocol conversion, and needs to remember the most recent or commonly used control state of the scene. DALI host can find all of the DALI lower position and assign the corresponding address and corresponding control. The main functions are as follows: 1) use Android smart phone as the operating platform to control the single lamp or the scene of the lamp 2) use the flat plate or PC as the operating tool to edit all the lamps in the system 3) through the software of the system within the address of the automatic distribution 4) to support real-time data storage and power down storage function 5) to support the host controller and the PC between a key upload and download function 6) support for multiple hosts in a system 7 through the home routing can achiev)

这是本人最近几年所编写的串行通讯的代码集，可以供大家参考学习。(recent years prepared by the serial communication code sets, we can reference for learning.)
