This project requires 3 Comparators and 3 DAC's the device you are trying to use only has 2 comparators and 2 DAC's so it will not fit the Cy8ckit-049-42xx. I guess you could use and external comparator using a LM339AN. and some kind of resistor network to replace the DAC's that is the reason they selected the CY8C5888LTI-LP097 for the project. This something you have to watch out when you are selecting a kit for a project. Also the Device you want to use adds additional issues due to the lack of a on board programmer. I would suggest that you modify the program or use the CY8CKIT-059 as the program calls for.
