About

This is is a one-day “idea to working prototype”-project. The VT-gauge is a analog gauge displaying how many minutes there are left until my next bus to my job depatures. The analog gauge is connected to a 18F2550 controller which in turn is connected trough USB to the computer (this is going to be replaced by ethernet for a stand-alone solution.). The computer is running a C# application which fetch the real-time information about the next depature and writes this to the uC. The application can also show CPU and RAM-usage on the gauge instead of the next depature.

Hardware

Prototype 1 Prototype v1. Works very well. Its 17 minutes to the next bus in this photo.

Software

Application Prototype v1. C# application. Writes next bus depature, current CPU or RAM usage or enables the uC-built in sweep-function.

Schematics

Schematic. Prototype schematic.

Firmware

The firmware is written in Microchip's C18 V 3.16 using MPLAB 8.00 and Microchip USB-stack 1.3
