# 2006 ECE Capstone Project Homepage

## Introduction

Since the [[successful but finally disastrous launch|news/2005-08-20]] of Launch Vehicle No. 2 (LV2), the PSAS Avionics Team has been redesigning the avionics system. This new system, called the "LV2b" avionics system, should avoid the limitations of the old system:

- Replace the Microchip PIC processors, which require Windows-based development tools and a proprietary commercial compiler, with a more open source microcontroller.
- Use a more sane communication protocols: either a more easy-to-use CAN system of IDs, or possibly switch to USB.

The goal of the PSAS Capstone team is to design the generic front-end that interfaces between all the nodes of the system (GPS, IMU, recovery system, etc) and the communication bus. This communication bus will be either a CAN bus or a USB 1.1 bus. The front-end will use an ARM chip; see below for the list of candidates.

The Capstone will last six months, so this design must be completed by June 2006. Capstone students are [[Sarah Bailey|SarahBailey]], [[Glenn LeBrasseur|GlennLeBrasseur]] and [[Jacob Davidson|JacobDavidson]].

## Design

### Bus Discussion

[[Bus discussion page|CapstoneLv2bBusDiscussion]]

- communication bus requirements for LV2b
- pros and cons of busses that might fit the criteria
- decision matrix for busses

### Hardware

- [[Microcontroller discussion|NodeMicrocontrollerSearch]]
- [[Switching power supply|SPSDesignPage]]
