Hi,

Please check if there is any problem at the renesas s5d9 board side. You can see some example codes for that device.

If you have any analyzer or oscilloscope you can probe the SCL and SDA lines and attach the screenshots of the bus images when the I2C master initiates the communication.

Please ensure that you are giving proper address of the I2C slave.

On your host side please check the error you are getting for the issue and write to renesas forums.

>>"i have check my keypad pcb in EZ click 2.0 and it is working."

--> Please check in Bridge control panel software also. The BCP (bridge control panel) will automatically gets installed when you download and install PSoC Programmer.

Please update your observations to this thread.

Thanks

Ganesh
