FPGA 芯片通过 I2C 总线连接 EEPROM 24LC04, I2C 的两根总线各上拉一个 4.7K的电阻到 3.3V,所以当总线上没有输出时会被拉高, 24LC04 的写保护没有使能,丌然 FPGA 会无法写入数据。因为在电路上 A0~A2 都为低,所以 24LC04 的设备地址为 0xA0。PGL12G 板子,是将FPGA芯片作为IIC ...
概述:I2C通讯接口,是我们日常应用中使用最多的MCU外设。最早在MCU没有硬件I2C之前,都是通过GPIO口模拟I2C的时序来完成I2C通讯的。后来MCU带有了I2C外设接口,其硬件I2C的使用也变成了日常。更主要的是,在节省MCU资源的同时,其操作也变得更加简单和易用。

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行擦除 ...
