使用STC89c58RD+系列单片机控制手机收发短信息的原理、硬件电路、PDU数据格式和短信息发送/接收程序，同时给出了一个应用实例。GSM采用的是西门子的TC35i,包括RS232串行接口,单片机采用STC89c58RD+，内部扩展RAM有256+1024字节的空间，可以作为短信缓冲区,1602液晶显示器（16引脚）作为显示模块和程序调试用(Use STC89c58RD+ Series MCU control handset to send and receive text messages of principle, the hardware circuit, PDU data formats and short message send/receive process, at the same time gives an application example. GSM is used by Siemens TC35i, including the RS232 serial interface, single-chip microcomputer used STC89c58RD+, Internal expansion RAM has 256+ 1024 bytes of space, can serve as a message buffer, 1602 Liquid Crystal Display (16 pin) as the display module and procedures for debugging)

说明：  随着人们对光谱测量仪器灵活性、 微型化的要求 ,便携式光纤光谱仪在实际生产测量中的需求也越来越大 ,对其测量性能的要求也越来越高。根据光纤光谱仪的测量原理 ,利用波长与CCD探测器单元格一一对应的关系 ,提出了一种波长校正的方案 ,波长校准精度可以达到0.5nm ,重复性达0.1nm。(Wit h people′ s requirement for spect rometer are agility and micromation , portable fiber spect rometer is needed more and more widely in practical measurement , and t he requirement for it s measurement capability get s more and more higher . According to t he measurement principle of t he fiber optic spect rometer and the cor responding relationship between t he wavelengt h and the CCD detector′ s cell , a wavelengt h correction met hod is p ut forward in t his paper , t he wavelengt h p recision can reach 0. 5nm and t he repeatability can reach 0. 1 nm.)

调用研华PCL数据采集卡进行采集数据例程，很容易理解，舍弃了繁琐功能！(Call Advantech PCL data acquisition card for data collection routines, it is easy to understand, abandoning the cumbersome features!)

stm32单片机控制激光雷达，激光雷达是目前比赛赛事中常见的传感器，更是无人车的必备(stm32 SCM laser radar, laser radar is common in tournament competition sensor, it is essential for unmanned vehicles)

51单片机中的LCD12864显示,用的是C语言，为KEIL程序包。(51 microcontroller in LCD12864 display)

巧用C8051F410的PCA实现超声波测距(Using the PCA to achieve ultrasonic ranging C8051F410)

NEC协议的红外遥控器解码程序，程序占用资源少，在51等单片机上验证OK。(ir decode for NEC protocal.)

说明：  使用STM32f103编程实例工程，有ADC、DMA、USART、TIMER、GPIO等编程讲解(STM32f103 programming example project, ADC, DMA, USART, TIMER, GPIO programming explanation)

说明：  uart DMA接收任意长度数据，稳定可靠(UART DMA receives data of arbitrary length and is stable and reliable)

利用51单片机结合超声波模块，编写的测距触发系统，程序可移植性好，具有人机界面，选用市售4脚传感器结合51机就可模拟，硬件简单。(The obstacle detection unit 51)
