The dedicated sensors and output devices on the FTMF Expansion Card are there to help you
quickly evaluate and experiment with a variety of PSoC applications, without having to build any
hardware. Your PSoC Express or PSoC Designer project completely determines the remaining
FTMF Expansion Card functions. Included in the kit installation are demonstration projects that use
the following input sensors:

The FTMF Expansion Card uses a standard FirstTouch expansion header for connection to the
FTPC bridge or other target hardware.
Notice that the 8x2 pin expansion header also includes four General Purpose IO connections labeled
P02-P05. These are hard wired to four unused Port 0 IO pins on the CY8C21434 host and allow you
to easily connect the FTMF Expansion Card to your specific hardware or sensors. These IO pins
were specifically chosen because they have the ability to operate as analog outputs, analog inputs,
digital inputs, digital outputs, or any combination of the four types; this pin selection makes them true
analog or digital GPIO.
Your PSoC Express project designates the specific function for these A/D GPIO pins.
