This System Diagnostic Tool (SDTool) can show your computer's current usage, like CPU and RAM. It will have multiple screen states which will show the following:
- Screen1: Current usage of CPU, RAM and HDD
- Screen2: Some system informations like processor, memory, and hard drive
- Screen3: Temperature measurement with DS18B20

On the other side, the C# Winform application will provide the necessary informations. This application will gather more informations about your PC, just to show you, but doesn't send it all to the PIC.

This project doesn't use FTDI, RS232 or anything to communicate. Only the PC's USB port communicate with a PIC18F4550 via a simple USB cable.
