最常用的英文缩写和短信缩写

最常用的英文缩写和短信缩写

最经常使用的英文缩写和短信缩写之南宫帮珍创作由于英文的字母太多,不方便的时候发短信很慢,所以外国人很多都在短信上输入缩写,这样就节省了很多时间。

需要说明的是,不是所有的人都明白这些缩写是什么意思,因为太多了,这里也不是所有的,只是选了一些比较有意思的,并标红了那些在英国最经常使用的。

从数字到Z的顺序列出,其实还蛮多的。

前面大写的是缩写(如果发短信的话不需要大写),后面附加的是英文和中文翻译。

大家可以快速过一下前面的英文缩写(但注重记一下标红的那些),建议花多点时间看看后面的英文解释,因为很多都是非常生活化,很外乡的英文短句,是出国留学的朋友们必须了解和明白的,中文翻译翻的比较中国化,没有那么生硬,这样大家应该能够更好的理解。

P.S (postscript附录):如果你知道还有什么很经常使用的英文缩写,请与我们交流。

24C04中文资料

24C02串行E2PROM的读写I2C总线是一种用于IC器件之间连接的二线制总线。

它通过SDA(串行数据线)及SCL(串行时钟线)两根线在连到总线上的器件之间传送信息,并根据地址识别每个器件:不管是单片机、存储器、LCD驱动器还是键盘接口。

1.I2C总线的基本结构采用I2C总线标准的单片机或IC器件,其内部不仅有I2C接口电路,而且将内部各单元电路按功能划分为若干相对独立的模块,通过软件寻址实现片选,减少了器件片选线的连接。

CPU不仅能通过指令将某个功能单元电路挂靠或摘离总线,还可对该单元的工作状况进行检测,从而实现对硬件系统的既简单又灵活的扩展与控制。

I2C总线接口电路结构如图1所示。

2.双向传输的接口特性传统的单片机串行接口的发送和接收一般都各用一条线,如MCS51系列的TXD和RXD,而I2C 总线则根据器件的功能通过软件程序使其可工作于发送或接收方式。

当某个器件向总线上发送信息时,它就是发送器(也叫主器件),而当其从总线上接收信息时,又成为接收器(也叫从器件)。

主器件用于启动总线上传送数据并产生时钟以开放传送的器件,此时任何被寻址的器件均被认为是从器件。

I2C总线的控制完全由挂接在总线上的主器件送出的地址和数据决定。

在总线上,既没有中心机,也没有优先机。

总线上主和从(即发送和接收)的关系不是一成不变的,而是取决于此时数据传送的方向。

SDA和SCL均为双向I/O线,通过上拉电阻接正电源。

当总线空闲时,两根线都是高电平。

连接总线的器件的输出级必须是集电极或漏极开路,以具有线“与”功能。

I2C总线的数据传送速率在标准工作方式下为100kbit/s,在快速方式下,最高传送速率可达400kbit/s。

3.I2C总线上的时钟信号在I2C总线上传送信息时的时钟同步信号是由挂接在SCL时钟线上的所有器件的逻辑“与”完成的。

SCL线上由高电平到低电平的跳变将影响到这些器件,一旦某个器件的时钟信号下跳为低电平,将使SCL线一直保持低电平,使SCL线上的所有器件开始低电平期。
