The PIC18F CTMU Evaluation Board (see Figure 4-2) is similar to the PIC24F CTMU
Evaluation Board except for the change in the number of ADC channels. The
PIC18F46J50 microcontroller on the PIC18F CTMU Evaluation Board has 13 ADC
channels, which are used by the touch sense application as the sensing channels.
The microcontroller uses its on-chip USB engine and transceiver to communicate to the
PC side interface application, using the USB mini-B receptacle. The evaluation board
also uses the USB receptacle for application power as a bus-powered device.
Microcontroller and LED power are provided from the V
voltage regulator. Provisions on the board allow for the users to add components and
create an externally powered application.

PIC18F CTMU Evaluation Board
PIC18F CTMU Evaluation Board firmware uses only 13 channels for touch
sense applications and Channels 13 to 15 are unused in the PIC18F CTMU
board.
Unlike the PIC24F CTMU Evaluation Board, the ICD interface (PGC and
PGD) on the PIC18F Evaluation Board does not share with any of the
CTMU channels.
