基于ARM7的GPRS实验代码(LCD320,键盘,I2C总线)

功能： 1、作为下位机采集8255数据并将此数据通过通讯送出，传输十路 2、采集数据为BCD，不处理后 3、通讯采用方式一-Features: 1, as under the 8255-bit machine data collection and data communications sent through the transmission path 2, 10, collecting data for the BCD, not after 3, means of communication using a

PC数字电压表的设计,原理图以及代码,设计文档.此数字电压表的优势在于可以通过串口将测量所得到的电压值传给PC机,这样的话有利用整个数据的采集与分析.上位机采取的是串口通信软件.-PC digital voltage meter design, diagram and code, Design Documentation. This figure voltage meter advantage is through the serial port will be measured by the voltage transmission PC, so is the use of the entire data collection and analysis. PC"s serial port communication software.

单片机课程设计指导－－源程序 89C52单片机+GSM模块-Singlechip curriculum design guidance- source 89C52 Singlechip+ GSM module

系统采用52单片机作为系统核心处理器，通过串口手法图像数据，利用那个TR800最为GSM模块，接收和发送图片。-System uses 52-core processor as the system microcontroller via serial port means the image data, using that TR800 most GSM module, to receive and send pictures.

HT1621 是一款128 个位元的LCD 控制器件，内部RAM 直接对应LCD 的显示单元。相应的软件使它适用于包括LCD 模块和显示子系统在内的多功能应用。主控制器与HT1621 接口只需4 到5根线。内置的省电模式极大的降低了功耗。-HT1621 is a 128-bit LCD control devices, directly correspond to the internal RAM of the LCD display unit. The corresponding software to make it applicable to including LCD modules and display subsystems, including multi-purpose applications. Host controller interface with HT1621 only 4-5 lines. Built-in power-saving mode greatly reduces power consumption.

单片机用T1中断在IO口P1.0输出乐曲(在P1.0口与VCC间接一喇叭即可听到) 1.由于输出的是方波，比较难听:-)你也可以将波形细分用DA输出正弦波 2.由于T1频繁中断，任何其他中断发生都会是乐曲打顿，只适合试验 3.优化音符编码：一个字节中包含节拍、音符、升降调，可区分数据和命令 -Single-chip microcomputer used in the IO port T1 interrupt output music P1.0 (P1.0 port with VCC in the indirect one can hear the speaker) 1. As the output is a square wave, more bluntly :-) You can also fine-waveform DA output sine wave with sub-2. Due to the frequent interruption of T1, any other interruption occurs Dayton will be playing music, is only suitable for test 3. optimized coding notes: A byte contains rhythms, notes, take-off and landing tune can distinguish between data and command
