So far this is just a test

gpsim is a simulator for Microchip (TM) PIC (TM) microcontrollers.
It supports most devices in Microchip's 12-bit, 14bit, and 16-bit
core families. In addition, gpsim supports dynamically loadable
modules such as LED's, LCD's, resistors, etc. to extend the simulation
environment beyond the PIC.

usbpicprog is a Microchip PIC programmer with simple hardware: one PIC18F2550 and some components.
It's therefore easy and cheap to build. Usbpicprog consists of 3 components: Hardware, Embedded
software and a stand-alone program for Win, Mac and Linux.
