i2c address
隨著科技的演進, 在單晶片微控制器及SoC 的領域中, SPI 及I2C 這二種串列(序列) 介面變得十分常見. 這二者與主機間通訊用的非同步串列通訊埠RS-232 (UART) 非常不一樣. ,We often get inquiries from our customers about what slave address to use in order to communicate with their I2C slave device. Unfortunately a lot of this confusion stems from the fact that different vendors follow different slave address conventions. The

常用I2C NVRAM 讀寫流程by Philips PCF8953. 一般RTC 都有帶一些NVRAM 或是讀寫EEPROM,需要先指定讀寫的register address 才可以。所以在寫時,先寫入slave address 後,需再寫入register address,讓chip 知道你要寫入的起始位址,接下來才能寫入data。 由於讀取前也要先寫入register address,所以一... http://jyhshin3.blogspot.com I2C bus 簡介(Inter-Integrated Circuit Bus) - 傑克! 真是太神奇了! - 痞客邦

I²C bus. I2C 使用兩條雙向open-drain Line:. SDA : Serial Data Line, holds Data or address signal; SCL : Serial Clock Line, holds Clock signal; 導通時是低電位,不導通時float,所以利用電阻(pullup resistor)將電位拉高。常用電壓為+5 V or +3.3... http://wiki.csie.ncku.edu.tw [通訊技術]小而美的I2C簡介-小型晶片之間溝通的橋樑– 實作派電子實驗室
相信你也看到了A2,A1,A0這甚麼東西呢?這個是讓user自行定義I2C address的功能(圖中稱呼為Control byte),若有需要同時使用兩顆EEPROM,user可以自行用IC的兩根腳位來定義I2C address。所以你可以在IC的A2~A0腳位上接Vcc或接GND用來表示1 or 0,這樣就能達成自訂address的目的 EEPROM_pinout. https://www.strongpilab.com Bear實驗室: 嵌入式系統基礎- I2C 基本原理介紹 - TAKOBEAR
我們馬上可以想到一個問題就是I2C可以傳輸多快呢? 一般來說I2C的標準是100 KHz, 菲利浦公司定義了faster speed mode可以傳輸高達400 KHz, high speed mode 更可以高達3.4Mhz. 不過正常來說還是用100KHz 為一個設計標準。 利用I2C溝通的時候還要特別注意到一件事情那就是Slave Address:每一個I2C ... http://www.takobear.tw I2C tutorial - Robot Electronics
