I2C on MCF51 w/ processor expert

Hello,

I am trying to interface with an SRF08 sonar using processor expert with the MCF51QE128. I have a couple questions:

1) Do I need to attach pull-up resistors to the I2C bus, or are these integrated onto the board?

2) I only get ERR_BUSY when I try to sendChar to my device (I already used selectSlave() to select the proper address).

Does anyone have any experience with this device or getting I2C to work on MCF51?

Thanks!
