8051F040的can总线底层驱动开发程序，可以移植到项目中。-The bottom of the can bus 8051F040-driven development process, can be transferred to the project.

控制电机运动的G代码程序,如果对G代码不清楚,请先看懂G代码,然后再看本程序.-Control motor movement, G code program, if the G code is not clear, please understand G code, and then look at the procedures.

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

该程序能捕捉到单片机发出的正确信号，并显示出来

利用串口和单片机进行通讯,VC用对话框实现-use serial communication and microcontroller, the VC using Dialog
