+-- BOARD DESCRIPTION
+-- -----------------
+-- --
+-- This file is the setup for my homebrew, PICDEM like 18f2550 board
+-- The board consist of a reset button switch to gnd (tied to pin1, with
4k7 pull up)
+-- A program button switch to gnd (tided to pin24, with 4k7 pull up)
+-- A 20 MHz external crystal and 15pf caps connected to OSC1/2
+-- pin 14 (Vusb) with a 220 nF capacitor to the ground
+-- The connection between PC and the 18F2450
+-- +5v to power the board
+-- data- wire to pin 15 (D-)
+-- data+ wire to pin 16 (D+)
+-- ground wire to the Vss of the PIC
+--
+-- In addition, a MAX232 chip connccted to the USART pins, for serial
(mainly to debug)
+-- communication.
+-- The board is loaded with the standard microchip bootloader, therefore
the examples
+-- are compiled with the following JAL compiler flags: -loader18 -no-fuse
