在下我最近練習用verilog 寫I2C，遇到以下問題
我用altera DE1的板子，用GPIO模擬I2C，對24LC64作讀寫的動作我寫入的資料是0x66，讀出來的資料卻是0xff
我有用分析儀看，卻找不出問題
懇請各位大大指點一下
補充:
寫入 start =>slave(0x57) =>write(黃色) =>address_high(0x00) =>address_low(0x55) =>data(0x66) =>stop
讀取 start =>slave(0x57) =>write(黃色) =>address_high(0x00) =>address_low(0x55) =>start =>slave(0x57) =>read(紫色)
=>data(0xff)(問題) =>stop
没看到你的具体内容
