The ARM7 board
Overview
One Member of the Concept Car's network is an ARM7 board. Due to its 32 bit architecture and higher frequency it provides a much bigger computational power than the AT90CAN128 boards. Thus it is well suited to do all the computation-intensive tasks.
Signal Flow
The AT90CAN128 actorboard offers a selection switch/jumper to choose between two different sources to generate its PWM output. By that you can select whether it uses direct input from the sensorboards or works on the preprocessed data from the ARM7 board.
The ARM7 board itself is not intended to directly access sensors or actors, it should merely process data from the CAN bus and produce control messages for the actor board.
Board Functionality
TODO bootloader, loading an app, memory management, ...
The most common use case for the ARM7 board is to execute a simulink model.
