I2C on JM128

Hello,

 

Im trying to communicate with an LCD via the JM128 demo board.   Im also using the Processor Expert software to generate the code. I have the IIC enabled with the jumpers on the demo board, initialized the I2C within my code, set the baud rate (less than 100kbps), and set the slave address.  Regardless, any attempt to communicate with the device is unsuccessful and receive an ERR_Busy reply.  Anyone out there have any experience working with I2C on this platform? Im new to the whole thing so Im not really even sure where to start troubleshooting.

 

Thanks,

Aric
