Installing an MQX driver - i2c

The doc set says that the i2c driver if enabled in the user_config.h file, may be installed in the BSP or application code. I can't see how to do either. When I do an install for cw10.1, mqx, 51jm128 as per the doc set and source files using

    _mcf51xx_i2c_polled_install("i2c0:", &_bsp_i2c0_init);

I get compile errors following on the next line of code. The address of the init structure is &_bsp_i2c0_init, and is from the board specific source file init_i2c.c, in that file we can see the structure. I added this to the build but still get errors. I tried moving the structure declaration to the function and get errors in compiling.

 

At this point we can't even get the app to compile. I have gone through the eeprom demo but that doesn't do it for us. I don't see how to change the structures and we need lower level api access as well for accelerometers and gyros.

 

I have read through all the doc sets and forums but can't find anything on installing drivers other than general guide lines and references.

 

Any starting point would be appreciated. Thanks
