The PIC32MX CVD Evaluation Board (see Figure 4-5) is similar to the PIC24F CTMU
Evaluation Board. The user interface look and feel do not differ, while the evaluation
board layout is almost identical due to the fact that the PIC32MX795F512H and
PIC24FJ128GB106 are pin-to-pin compatible. The four daughter boards are connected
to the J3/J4 connectors in the same manner. As for functionality, the PIC32MX CVD
evaluation board has 15 LEDs to indicate touch sensing while the USB interface is
used for communicating with the host application for visualization and diagnostic.
A major difference between the PIC24F CTMU and the PIC32MX CVD evaluation
boards is the PIC32MX CVD uses the ADC module for capacitive touch sensing, while
the PIC24F CTMU uses the dedicated CTMU module.
