The microprocessor is the heart of the 2007 RoboJackets RoboCup competition robot and acts as the interface between the wireless communication system and the robot proper. A simple firmware program monitoring the internal sensors of the robot and controling the motor and ball roller/shoot will run on the micro. Currently as part of our phase one objectives we are looking closly at processors from Atmel, SI Labs, Motorola, and PICs. Below are some specs.

The Wall
9/14/06 - We chose a dev kit see the sparkfun link below. It'll cost $64.95 a pop and we are getting 3. 11/23/06 - Set the frequency of the mirco and added the crystall its needs
To Do
- Finalize number of I/O and type (SPI, PWM, ADC, etc)
- Design Schematic tying in all devices
- Breadboard to test write simple code
- Get board made
- Write Code

User Groups/Wikis
- Yahoo group about just the LPC ARM from Phillips
- Yet Another Discussion Group
- ARM Wiki - Good page with a lot of ARM resources/links. ScottT
- Page of ARM processor instructions - ASSEMBLY instructions, if we need them. ScottT
- Apparently free ARM course - Not sure how useful this could be. ScottT
Software
- Bray++ Terminal (just download/run, no install!)
- WinARM ARM development programs for Windows
- ARM processor simulator for Linux - might be able to use this to test things, but I'm not sure it would be better than just taking home a dev board. :P ScottT
