CAN的调试程序。CAN的初始化重要包括下面几个方面。RXB0SIDH，RXB0SIDL，RXB0MIDH，RXB0MIDL。这是接收过滤器。TXB0SIDH，TXB0SIDL，TXB0DLC，这是发送标志位。还有波特率寄存器。操作模式为 正常模式。-CAN debugging procedures. CAN initialization important aspects include the following. RXB0SIDH, RXB0SIDL, RXB0MIDH, RXB0MIDL. This is the receiver filters. TXB0SIDH, TXB0SIDL, TXB0DLC, it is sending signs spaces. There baud rate register. The normal mode of operation for the model.

用C51做的计算器源码，矩阵键盘，液晶显示，C和ASM混合编程，PROTUSE自带的例程-C51 calculator to do with source code, matrix keyboard, LCD, C and ASM programming mixed, PROTUSE built-in routines

这篇程序是我一个同学编的,并且已经应用到了二相步进电机(四线步进电机)上了.但是我认为此程序需要改进的地方有很多. -This procedure is a fellow student, I made and have been applied to a two-phase stepper motor (four-wire stepper motor) on. But I think this process needs to be improved where there are many.

基于C8051F040的液晶，键盘交互式程序，其中液晶和键盘高质量处理函数都已经模块化了，用户可以直接使用-C8051F040-based LCD, keyboard interactive procedures, which deal with high-quality LCD and keyboard functions have been modular, and users can directly use
