Description: 这是本人的一个正式项目中所做的测试工程源码。主要功能是通过串口与板子的GSM模块进行通讯，进行收发短信的程序。内容有：串口设置，GB2312与UNICODE编码转换，PDU编解码（此部分大部分借鉴了网友的代码）,AT指令发送。完全可以将相关代码移植到嵌入式短信收发设备中去。我的相关嵌入式项目也确实是在这个基础上做的。-This is my project done by a formal evaluation of the source. Main functions of the board through the serial port and the GSM communication modules for the process to send and receive text messages. Are as follows: serial port settings, GB2312 with UNICODE encoding conversion, PDU codecs (most of this part of the code from the User), AT commands to send. Relevant code can be ported to embedded devices to send and receive text messages. My embedded projects related is on this basis to do so. Platform: |

Description: Serial Advanced Technology Attachment (SATA) is a serial link replacement of
Parallel ATA (PATA), both standards for communication with mass storage devices.
This high-speed serial link is a differential layer that utilizes Gigabit technology
and 8b/10b encoding. Some of the features of SATA compared to PATA
are increased transfer speed, hot-plug capability, and Native Command Queuing
(NCQ). The link supports full duplex but the protocol only permits frames in one
direction at a time. The other non-data direction is used for flow control of the
data stream.
Figure 2.1. The layers of the SATA protocol
SATA’s architecture consists of four layers (see Figure 2.1), Application, Transport,
Link, and Physical. The Application layer is responsible for overall ATA commands

Description: This document describes the MODBUS over Serial Line protocol. MODBUS Serial Line protocol is a Master-Slave protocol. This
protocol takes place at level 2 of the OSI model.
A master-slave type system has one node (the master node) that issues explicit commands to one of the "slave" nodes and processes
responses. Slave nodes will not typically transmit data without a request from the master node, and do not communicate with other
slaves.
At the physical level, MODBUS over Serial Line systems may use different physical interfaces (RS485, RS232). TIA/EIA-485 (RS485)
Two-Wire interface is the most common. As an add-on option, RS485 Four-Wire interface may also be implemented. A TIA/EIA-232-
E (RS232) serial interface may also be used as an interface, when only short point to point communication is required. (see chapter
"Physical Layer") Platform: |

Description: 以AT89C51单片机系统为核心，能对多点的温度进行实时巡检。各检测单元（从机）能独立完成各自功能，同时能够根据主控机的指令对温度进行定时采集，测量结果不仅能在本地显示，而且可以利用单片机串行口，通过RS-232总线及通信协议将采集的数据传送到主控机，进行进一步的存档、处理。主控机负责控制指令的发送，控制各个从机进行温度采集，收集测量数据，并对测量结果（包括历史数据）进行整理、显示和存储。主控机与各从机之间能够相互联系、相互协调，从而达到系统整体统一、和谐的效果。(Taking AT89C51 single chip microcomputer system as the core, the real-time inspection of multi-point temperature can be carried out. The detection unit (slave) can independently function at the same time, according to the master machine instructions are collected on the temperature measurement results, not only in the local, but also can use the microcontroller serial port, through the RS-232 bus communication protocol and the data collected will be transmitted to the host computer, and further processing of the archive. The main control machine is responsible for the transmission of control commands, control the temperature acquisition of each slave, collect measurement data, and collate, display and store the measurement results (including historical data). The main controller and the slave machine can be connected and coordinated with each other, so as to achieve the overall unity and harmony of the system.) Platform: |
