SPI_2543_uart

宽频放大器,有以下功能: 预置增益,增益加/减,显示输出电压有效值,自动增益 显示有效值. 增益输入及加减 自动增益没有实现(Wideband amplifier has the following functions: Preset gain, gain plus/minus, the display output voltage RMS, automatic gain display rms. AGC gain input and subtraction is not implemented)

说明：  系统工作电源AC220V 根据室内光线调节遥控灵敏度。 主控室电脑负责接收由控制终端传来的遥控信号播放相应多媒体影音文件； 通过主控电脑也可直接点播各展品文件，同时控制打开对应的展品照明； 遥控终端接收激光棒控制信号，控制开灯照明正在解说的展品，并通过通信总线通知主机播放相应文件； 通信中继器负责全部终端与主机间的双向信号传递； 扩展功能：设计上位机播放操作软件，控制照明灯亮度。 (无)

51单片机编程器制作资料。内有pcb，原理图，物料清单，hex文件。自制成功(51 Microcontroller Programmer production of information. There pcb, schematics, BOM, hex file. Self-made success)

说明：  双路输出控制器”具有信号输出时间设定、 输出信号占空比调整、 当前输出通道及时 间显示、系统工作参数存储、串口通讯及 LED 指示等功能。 “双路输出控制器”通过串口完 成信号输出时间设定功能；通过 EEPROM 完成系统工作参数存储功能；通过按键完成输出通 道切换、 输出信号占空比调整及停止信号输出功能； 系统硬件电路主要由 MCU 控制单元、独 立按键、 LCD 显示单元、 串口通讯单元、 EEPROM 数据存储单元和 LED 指示单元组成(Dual output controller has the signal output time setting, adjust the duty cycle of the output signal, the current output channel in time Between display, system operating parameters are stored, serial communications and LED indicator. Dual Output Controller through serial END A signal output time setting function complete system operating parameters via EEPROM memory function complete output pass through the key Channel switching, adjust the duty cycle of the output signal and the stop signal output function the system hardware circuit is mainly controlled by the MCU unit, alone Li buttons, LCD display unit, serial communication unit, EEPROM data storage unit and LED indication units)

99秒马表，在Proteus设计两个数码管动态显示及一个键盘SP。在ucos下结合keil完成开始时，显示“00”，第1次按下SP后就开始计时。 第2次按SP后，计时停止。第3次按SP后，计时归零。 (99 seconds stopwatch, two in the Proteus design dynamic digital tube display and a keyboard SP. Keil in combination ucos completed under the beginning of the show " 00" , 1st timer after pressing the SP. 2nd by SP, the time to stop. The 3rd by the SP, the time zero.)
