通讯设置程序，主要是串口通讯子函数和控制数据流。

The ADC0803 family is a series of three CMOS 8-bit successive approximation A/D converters using a resistive ladder and capacitive array together with an auto-zero comparator. These converters are designed to operate with microprocessor-controlled buses using a minimum of external circuitry. The 3-State output data lines can be connected directly to the data bus.

这是一个波形选择菜单，通过开发板上的按键，选择波形，幅度，频率的等各参数，然后发送给下位机。让其产生需要的波形。-This is a waveform selection menu, through the development of on-board buttons, select the waveform, amplitude, frequency and other parameters, and then sent to the next bit plane. The need to generate the waveform.

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

这是AD转换芯片AD7705的初始化程序，主要是寄存器的配置-This is the AD conversion chip AD7705 initialization procedure is the configuration register

便携式压力传感器，带usb口和ic存储卡的-portable pressure sensors, with USB port and memory card ic

这是我用汇编语言编写的计时器程序，通过计算机发命令开始倒计时，其中也有其他功能，但主要是倒计时，比较好用，这是个小程序，穿上来了表心意-This is the language I used compilation prepared by the timer procedures, through the computer started the countdown orders, which also has other functions, but the countdown is more convenient, it is a small program to put on the table liking

该程序能捕捉到单片机发出的正确信号，并显示出来
