i2c总线对于单片机的扩展很有帮助, 可以通过两个i/o口进行大量的扩张. 这是一个i/c的应用程序.-i2c Bus for the expansion of SCM helpful, through two i/o Hau substantial expansion. This is an i/c applications.

本文详细介绍了4×4矩阵式键盘识别技术，内含详细的电路图和C51源代码。-This paper describes a 4 × 4 matrix keyboard recognition technology, and contains detailed schematics and source code C51.

在c51下液晶显示块LCD20040411的编程实例。-Under the liquid crystal display in the C51 block LCD20040411 programming examples.

ADC0809是广泛使用的模／数转换器，在可不采用外部总线结构的单片机系统中(如 由AT89C51组成的系统)。ASC0809的数据线直接与单片结构的I／0 口相连，并由单片机的I／O 口直接对ADC0809进行控制。-ADC0809 is widely used in analog/digital converters, in not using the external bus architecture in the single-chip microcomputer system (such as the composition of the system by the AT89C51). ASC0809 data lines directly with the monolithic structure of I/0 I connected the MCU I/O port directly to control the ADC0809.
