STM32F0单片机快速入门九用 I2C HAL 库读写24C02

1.24C02介绍24C02 现在基本是开发板的标配，对于需要掉电存储的应用来说确是不二选择。现在单片机因为内部集成了Flash存储器，一般也都支持数据的掉电保存，但相对于 24C02 这种 EEPROM 来说，使用单片机内部的 Flash 有一些需要注意的问题：a.Flash 写入数据之前需要先执...

【STC15单片机】模拟I2C操作AT24C02数据读取，PCF8591的A/D转换代码

PCB上线的长短可能影响数据传输的时间，写I2C时序可能就要加一点延时！！！！！！I2C时序结构起始条件：SCL高电平期间，SDA从高电平切换到低电平终止条件：SCL高电平期间，SDA从低电平切换到高电平发送一个字节：SCL低电...

单片机：I2C--EEPROM（I2C介绍+AT2402+硬件设计+软件编程＜重点是软件编程部分＞）

1.支持多设备连接，多主机，多从机2.SDA:数据线，发送收发数据SCL：时钟线，实现数据同步3.每一个连接在总线的设备都有一个地址，通过地址来访问设备4.总线有上拉电阻，当设备空闲时，默认为高阻态5.多个主设备同时使用时，通过总裁方式决定那个主设备占用总线6.传输模式&...

[51单片机] EEPROM 24c02 [I2C代码封装-保存实现流水灯]

这里把EEPROM 24c02封装起来，今后可以直接调用，其连线方式为：SDA-P2.1;SCL-P2.0;WP-VCC >_<:i2c.c 1 /*----------------------------------------------- 2 名称：IIC协议 3 内容：函数是采用...
