I presume you must have added an I2C Master to the PSoC Designer project. If not, you will have to create a PSoC Designer project, using CY8CPLC20 as the device, and add an I2C Master. Another possibility is that we do not have I2C pull-ups installed on the board. You can try adding pull-up resistors of 3k3 and see if you can see the clock.
Thanks and Regards,
I can see that there is a provision for pull-ups at P1.7 and P1.5. Use jumpers at JP3 and JP4. Sorry for the mistake in the prior post.
Firstly thanks for the reply,it means a lot,i will try it let you know
