APPLICATION SIDE BLOCK DIAGRAM
The application side of the starter kit is centered on the PIC24F256GB106
microcontroller, which requires very little additional hardware to perform its tasks. All
application code is stored in the device’s Flash program memory. In addition to the
application core, the preloaded demo uses substantial parts of the Microchip USB
Stack Library, the Microchip Memory Disk Drive File System and the Microchip
Graphics Library to function.
The application accepts user inputs from the capacitive touch pad (S1) and the
potentiometer (R44). The microcontroller uses one of its A/D converter channels to
sample and convert the potentiometer’s value to a digital value for the Data Graphing
and Data Capture demos. Five additional A/D channels are used to monitor the
individual touch pads of S1. The values from these channels are analyzed with the
CTMU to determine when a touch-and-release event occurs on any of the pads. The
application firmware determines which action to take based on the application’s current
context.
