    I2c master transmit problems on CYBLE-014008-00

      Hey All,

         

       

         

           I am using PSoC Creator 4.0 for the CYBLE-014008-00  and I have an I2C bus set up on pins 1.4 and 1.5 which is SCB0.  I am pretty new to PSoC but when I set up an O-Scope on all pins and run the example project SCB_I2cCommMaster01 code, I don't even see a clock signal, and it gets hung up here:

         

       

         

       /* Waits until master completes write transfer */
          while (0u == (I2CM_I2CMasterStatus() & I2CM_I2C_MSTAT_WR_CMPLT))
          {
          }

         

       

         

      I think i am missing something, but for the life of me, I can't figure out what it is.
