For implementing the matrix keys with PSoC3 all you need to do is scan all the sensors and check if any of the sensor is active. Based on the active sensor number we detect the key which is pressed in the matrix. There is an example project on CY website: http://www.cypress.com/?rID=39262 which shows how to use matrix keyboard with Smartsense. Same way it can be used with PSoC3 just the scanning APIs and configuration settings are different.
