Abstract
A new intelligent milometer base on a microcontroller can count the sum. By taking full use of the processor 89s51 and E² PROM (AT24C02) and sensor of magnetism, it can count the sum of fully distance and the course of development.
单片机编程 16-bit IC and SMBus I/O Port w
The CAT9555 is a CMOS device that provides 16-bitparallel input/output port expansion for I²C and SMBuscompatible applications. These I/O expanders providea simple solution in applications where additional I/Osare needed: sensors, power switches, LEDs,pushbuttons, and fans.
测试测量 硅中磷杂质的SIMS定量检测
样品的前期处理工艺会对检测结果产生影响。不同处理工艺得到的样品,在表面粗糙度方面产生区别。不同的表面粗糙度,影响到样品的测试时间和测试精度。同时,通过仪器调试,仪器的真空度达到1×10-10  torr,使测试背底和检测限降低。

单片机编程 P90CL301 I2C driver routines
This application note shows how to write an Inter Integrated Circuit bus driver (I²C) for the Philips P90CL301micro-controller.It is not only an example of writing a driver, but it also includes a set of application interface software routines toquickly implement a complete I²C multi-maste ...
技术资料 2线总线上升时间加速电路
摘要：包含2线总线(例如：I²C或SMBus™)的应用需要在上升时间、电源损耗、噪声抑制等参数之间做出折中。这种漏极开路总线从低电平跳变到高电平的上升时间由上拉电阻和总线电容决定
单片机编程 基于CPLD的线阵CCD驱动的实现
摘 要:本文以日本东芝公司的线阵CCD器件TCD1206SUP为例,在研究了线阵CCD器件工作原理和驱动电路波形的基础上,介绍了采用图形式层次设计方法,用复杂可编程逻辑器件(CPLD)设计线阵CCD驱动脉冲的实现方法。用一片EPM7064设计出TCD1206SUP正常工作所需的驱动波形,减小了驱动器的体积。讨论了电路的工作原理和设计特点,同时给出 ...
