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 ...

This application note describes how to control an external EEPROM by using the I2 C bus features. The sample code shown in this application note writes and reads 4-byte (word) data to and from the ...
