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
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

Possible Micros
- Phillips LPC213x series ARMs. Less memory than the LPC221x series but lower-power consumption and smaller footprint. Its still every bit as capable
- Phillips LPC221x series ARMs. More memory vs LPC2213x. COntains everything we need.
- ATMEL's answer to the ARM. Has everything including the kitchen sink.
