相信很多读者都使用过类似AT24C0x这种使用I²C读写的EEPROM，在项目中，使用不当就容易导致数据丢失，或者异常的情况。 今天，我们就来讲讲关于EEPROM的内容。 市面上大部分使用I2C通信的EEPROM，控制时序和读写流程都基本相同。 I²C通信原理，说简单不简单，但 ...

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 ...
