Description:
The Microchip Technology Inc. 24C02C is a 2K bit Serial Electrically Erasable PROM with a voltage range of 4.5V to 5.5V. The device is organized as a single block of 256 x 8-bit memory with a 2-wire serial interface. Low-current design permits operation with max. standby and active currents of only 5 μA and 1 mA, respectively. The device has a page write capability for up to 16 bytes of data and has fast write cycle times of only 1 ms for both byte and page writes. Functional address lines allow the connection of up to eight 24C02C devices on the same bus for up to 16K bits of contiguous EEPROM memory. The device is available in the standard 8-pin PDIP, 8-pin SOIC (3.90 mm), 8-pin 2x3 DFN and TDFN, 8-pin MSOP and TSSOP packages.

前言 在實(shí)際的應(yīng)用中，我們需要一些存儲(chǔ)介質(zhì)幫助我們來(lái)存儲(chǔ)一些東西，如保存一些參數(shù)和配置數(shù)據(jù)等。比較常用的有AT24Cxx系列。AT24C02芯片是以IIC接口的EEPROM器件。所謂EEPROM即電
基于APM32F407如何制作I2C EEPROM（AT24C02型號(hào)）的Keil下載算法，這樣在我們下載代碼時(shí)可以一鍵把數(shù)據(jù)燒錄到EEPROM中。
AT24C01/02/04/08/16...是一個(gè)1K/2K/4K/8K/16K位電可擦除PROM，內(nèi)部含有128/256/512/1024/2048個(gè)8位字節(jié)，AT24C01有一個(gè)8字節(jié)頁(yè)寫(xiě)緩沖器，AT24C02/04/08/16有一個(gè)16字節(jié)頁(yè)寫(xiě)緩沖器。
現(xiàn)在我們已經(jīng)實(shí)現(xiàn)了AT24C02的單字節(jié)讀寫(xiě)，但是對(duì)于對(duì)于2K內(nèi)存來(lái)說(shuō)，如果對(duì)全部數(shù)據(jù)的讀取或者寫(xiě)入都只用單字節(jié)讀寫(xiě)來(lái)完成，這樣就會(huì)很不方便。
上次已經(jīng)完成了IIC讀寫(xiě)AT24C02的協(xié)議層，現(xiàn)在開(kāi)始編寫(xiě)讀寫(xiě)AT24C02的驅(qū)動(dòng)函數(shù)。先從單字節(jié)的讀寫(xiě)開(kāi)始。
要用IIC讀寫(xiě)AT24C02，首先要了解IIC是什么。
使用Platformio平臺(tái)的libopencm3開(kāi)發(fā)框架來(lái)開(kāi)發(fā)STM32G0，以下為EEPROM M24C02的使用方法。
本文是IIC總線的實(shí)際應(yīng)用，將帶領(lǐng)讀者一步一步閱讀AT24C02數(shù)據(jù)手冊(cè)，看時(shí)序圖了解如何使用IIC接口EEPROM存儲(chǔ)模塊AT24C02，并編寫(xiě)代碼使用STM32驅(qū)動(dòng)這個(gè)模塊。
