Hello:

I need help for my project with PSoc 4000 Pioneer kit.

I drag an I2C component onto cysch from Cypress Component Catalog. However,  on cwdwr page it doesn't allow me to link the SDA/SCL to PSoC 4000 pins P3[1]/P3[0], only allow me to link to P1[3]/P1[2].

I would like to use Bridge Control Panel to debug. so I need the pin assigned to SWD debug.

Please help me to solve this problem.

Thanks.

Regards;

Chang

Hi Chang,

You can enable those pins to use other purpose in .cydwr file in PSoC Creator.

Click the [System] tap and change the Debug Select option from SWD to GPIO, then you can use P3[1]/P3[0] pins for I2C.

Please refer attached image.
