MC13224V I2C

Having Problems with I2C Interface on SRB Sensor Board.

I used sound.c as an example.


I called JC_I2C_Init first, then I2c_Enable which returned code 0 (success)

If I call I2c_Enable a second time I get a return code of 1 indicating I2C is already Enabled


The problem is that when I call I2c_SendData the code hangs there forever.


An oscilloscope shows no activity on Data or clock leads.


Is there an application for the demo board using I2C that can be compiled and run. THe demos I see don't appear to actually call the functions in the sound.c code.


Any thoughts?
