CAN控制器SJA1000的标准帧，BsaicCAN模式，调好的初始化、发送、接收底层程序，大家共享。-CAN controller SJA1000 standard frame, BsaicCAN mode, tune good initialization, send, receive the bottom of procedures, for all to share.

本程序主要通过外部中断INT0及3.3端口读取PS2键盘值并通过LCD1602显示，键扫描码的解码通过数组方式解码，程序的解码功能主要针对数字及大小写字母和常用标点符号 硬件描述：PS2键盘的时钟线（clk）接89S51的INT0（P3.2）,数据线data接（P3.3） LCD的控制端口分别为： RS = P2^7，RW = P2^6，EP = P2^5，数据端口为P0，液晶显示偏压VL必须接 -This procedure mainly through external interrupt INT0 and 3.3 read PS2 keyboard port value through LCD1602 display, key scan code decoder way through an array of decoding, the procedure for decoding function of the major figures and upper and lower case letters and punctuation marks commonly used hardware description: PS2 keyboard clock line (clk) then 89S51 the INT0 (P3.2), data lines data access (P3.3) LCD control port, respectively: RS = P2 ^ 7, RW = P2 ^ 6, EP = P2 ^ 5, data ports for the P0, LCD bias VL must be received

HT1621的驱动文件，对于测试段码液晶比较有用，部分程序参考了别人。-HT1621 driver files, for testing liquid crystal above code more useful, some of the procedures with reference to others.

利用单片机控制实现的计算器，用lcd显示计算的过程和结果。-SCM control to achieve use of calculator, lcd display with the calculation process and results.

蜂鸣器响 改变蜂鸣器的频率，通过改变延时时间 蜂鸣器的时间要是是靠延时来完成的-Buzzer buzzer ring to change the frequency by changing the delay time if the buzzer is the time to be completed by the time delay

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.

很有用的一些从用代码 有keil编译实现的 可以-Useful to have some code from keil compiler can realize
