    PSoC 3 - Programming Connections/Pins

    alex.b

      Hello All,

         

      I am in the process of making a board using the PSoC 3 chip.

         

      I was using the schematics of the CY8CKIT-030 as a reference. In that design, there is a 10 pin header. My questions are as follows:

         

      1) What are the connections needed for the chip to program & debug? In the reference schematic, they have:

         

      p10 - SWDIO

         

      p11 - SWDCK

         

      p13 - SWO

         

      p14 - TDI

         

      These seem to be JTAG. I though miniprog 3 could do SWV/SWD which only required 2 pins? Please clarify.

         

      2) Where can I find the female header to put on the board? I looked at Digikey, and they seem to be out of stock.

         

      3) What should I do with the USB pins if I choose not to use them?

         

      Thanks,
