介绍tc35i与单片机通信的汇编语言编程方法。-TC35i introduce single-chip communications and assembly language programming.

8051核的DES源代码 使用C语言写的基于51核的DES原码，变量定义使用汇编。占用了130字节RAM，比我所见到的包括汇编编写的都要快。 -8051 nuclear DES use source code written in C language based on the 51 nuclear DES original code, the use of variable definition compilation. Occupy the 130 byte RAM, than I have seen in the preparation of the compilation must fast.

一个ADC0809的程序,很有用的,不放试一试-a ADC0809 procedures useful, link test

与中断矢量设置与读取有关的DOS功能调用，本例演示了如何编写中断服务程序，如何安装（将中断服务程序的地址设置到中断矢表中），以及如何通过软中断指令调用中断服务程序。为了突出重点，本例中中断服务程序代码未驻留内存。-and vector interrupt settings and read the DOS function calls, which in this case demonstrated how to prepare interrupted service procedures, how to install (to be interrupted service procedures set up to address the interruption vector table), and how soft interrupt directive calling service interruption program. To highlight key issues, in this case the interruption of services not the presence of code memory.
