    SPI Communication

    mohd.zulhadi.zainal.abidin

      Hi,

         

       

         

      I posted my question in the other forum but got no answer.

         

      The problem was I 'm trying to make 2 PSoC chip communicate via SPI.

         

      PSoC5LP as master and  the PSoC4 as slave.

         

      The problem is, MISO line (P0_2) of the PSoC5 seem to pull the pin low.

         

      I have change the pin to P3_0 and everything works as expected.

         

      Can anyone explained what happened?is P0_2 (Opamp ) input cannot be buffered?

         

      Thank you.
