APPLICATION SIDE BLOCK DIAGRAM
The application side of the starter kit is centered on the PIC18F46J50 microcontroller,
which requires very little additional hardware to perform its tasks. The MPLAB Starter
Kit for PIC18F comes preprogrammed with a MicroSD bootloader that has the ability to
load, program and run precompiled applications from a MicroSD memory card to the
device’s Flash program memory. The MicroSD bootloader uses substantial parts of the
Microchip Memory Disk Drive file system. The precompiled demos use substantial
parts of the Microchip USB Stack Library.
The applications accept user inputs from three sources: the capacitive touch pad, S1
(A5), the acceleration sensor, U6 (A4), and the potentiometer, R24 (A7).
