3.2 XPRESS bootloader
The XPRESS bootloader allows for easy drag and
drop programming.
When plugged into the USB it will show itself
as a flash drive onto which you can simply
drag a hex file for your MCU. The hex file can
be generated by any compiler. After the hex file
is placed onto the clicker 2 for PIC18FK it will
program the main MCU. This functionality is
enabled by the PIC16F1454 which acts both as
a drag and drop programmer and Virtual COM
port. The additional bootloader in the main MCU
is not needed for this to work.
