Hello.

Did you put pull-up resistors on clock and data pins?

[bytedance]

yes

Hi @bytedance,

I would suggest you to go through the I2C code example present for PSoC 4000 device: CE222306 - PSoC 4 I2C Communication with Serial Communication Block [zip file] [CE document ].

As @BiBi_1928986 mentioned, ensure that you have the hardware components, both the series and the pull-up resistors, connected to the I2C lines. If you are using a terminal/bridge control panel to view your I2C messages, make sure you have the right settings for communication speed and addressing mode. 

Regards,
Nikhil
