1. EXT_C.rar, 给初学者(带中文注释的C51语言例程), 利用外部中断实现LED灯的简单控制。

2. EXT_A.rar, 给初学者(带中文注释的51汇编语言例程), 利用外部中断实现LED灯的简单控制。

两个同样功能的中断例程, 一个用C51实现, 另一个用ASM51实现。-1. EXT_C.rar for beginners (with Chinese translations of routines C51), The use of external LED lights interrupted the simple control. 2. EXT_A.rar for beginners (with Chinese translations of the 51 assembly language routines). The use of external LED lights interrupted the simple control. 2 the same functions interrupt routines, with a C51, and the other using Calling achieve.
