一款非常实用LCD16*2 液晶程序(时钟程序).仅供大家学习参考用-LCD16* 2 LCD (clock procedures). We only used to learning

利用51单片机控制DS18B20温度传感器采集温度，并利用无线传输模块PTR6000将温度值进行传送，很实用的程序，绝对原创和好使！-SCM control DS18B20 using 51 temperature sensors collect temperature, and using wireless transmission module PTR6000 to send the temperature value is very useful procedure, the absolute original and so!

串口双工通讯，单片机上用LCD显示主机发送的数据，同时可以通过单片机的按键向主机发送多种数据-Duplex serial communication, single-chip LCD display with a host to send data at the same time can be key to the host MCU to send multiple data

这是一个关于PS2的C语言程序，利用单片机进行调试，非常好用-This is a C-language program on the PS2 using the microcontroller for debugging, very easy to use

程序能够实现将十二位的二进制数5V对应fffH变换成一路0~5V的电压。 精度方面：在使用时上下波动范围大约是0~2fH能保证高位寄存器准确； 调试过程中遇到了一系列问题：（1）p0口的使用需接上拉电阻，内部没有带电阻；（2）调试的过程最好使用单步运行，以便于察看寄存器的内容；（3）对系统板不熟悉，一些硬件方面容易出问题，像口连接，电源、地的连接。（4）直流电源使用不准确，内部的各个电源输出是独立的，需要共地。 -procedures to achieve 12 to a binary number 5V counterparts fffH transform all the way into the 0- 5V voltage. Accuracy : the use of fluctuating ranges of 0 ~ 2fH can guarantee accurate high register; debugging process encountered a series of questions : (1) p0 I need to connect to the widening use of resistance, with no internal resistance; (2) the process of commissioning the best use of single-step operation, in order to inspect the contents of Register; (3) The right not familiar with the system board, Some hardware problems are likely to occur, such as connectors, power, and connectivity. (4) DC power supply use of inaccurate, all within the Power output is independent, to the total needs.

通讯设置程序，主要是串口通讯子函数和控制数据流。-Communications setup program, mainly Serial Communication Function and control of data streams.

12864液晶在出厂时其对比度已经调好，所以用户在使用的时候第三管脚可不用接任何东西，本实验板上为了兼容多家12864液晶所以加了液晶对比度调节电位器，若用户使用我们配套的12864液晶可不用管它，液晶的第三管脚悬空就可以。有些液晶功耗比较大，用户在使用的时候可将液晶的第19、20引脚的背光不接，这样字体会很清楚-12864 LCD contrast, when the factory has a good tune, so when users can not access the third pin anything, this experiment in order to compatible with more than 12,864 on-board LCD so the addition of LCD contrast adjustment potentiometer, if users supporting our 12864 can not regardless of LCD, LCD" s third pin can be left vacant. Some relatively large power consumption of LCD, users can be used when the first 19,20 LCD backlight will not receive the pin, so that fonts will be very clear
