I’m suffering from a problem with the I2C. https://i.imgur.com/y5PR0Vc.jpg The device could list the I2C info, but W/R would cause the above error message.

We also used a digitizer to capture the output signal with the setting of address 0x53, data 0xff. https://i.imgur.com/9FWb69f.jpg There is only the address. I'm not sure is there something wrong?

That's all my mistake. The EEPROM address should be 0x50 in the HW connection. I2C connection is workable.
