单片机编程 Input Signal Rise and Fall Tim
All inputs of the C16x family have Schmitt-Trigger input characteristics. These Schmitt-Triggers are intended to always provide proper internal low and high levels, even if anundefined voltage level (between TTL-VIL and TTL-VIH) is externally applied to the pin.The hysteresis of these inputs, howeve ...

单片机编程 XA-S3 I2C driver software
This application note demonstrates how to write an Inter Integrated Circuit bus driver (I2C) for the XA-S3 16-bitMicrocontroller from Philips Semiconductors.Not only the driver software is given. This note also contains a set of (example) interface routines and a smalldemo application program. All t ...
单片机编程 Using the 87LPC76X microcontro
I2C interface, is a very powerful tool for system designers. Theintegrated protocols allow systems to be completely software defined.Software development time of different products can be reduced byassembling a library of reusable software modules. In addition, themultimaster capability allows rapid ...

单片机编程 PIC单片机程序设计基础
1、程序的基本格式先介绍二条伪指令：EQU ——标号赋值伪指令ORG ——地址定义伪指令PIC16C5X在RESET后指令计算器PC被置为全“1”，所以PIC16C5X几种型号芯片的复位地址为：PIC16C54/55：1FFHPIC16C56：3FFHPIC16C57/58：7FFH一般来说，PIC的源程序并没有要求统一的格式，大家可以根据自己的风格来编写。但这里我们推荐一种 ...
