Software Design

2. Overview Two main subsystems
Battery monitoring board
Main controller board
Each board uses different approach to software
Polling vs. interrupt-driven

3. Battery Monitors
Battery monitor code will be implemented as a polling loop
Power consumption is more important than raw speed, so sampling rate is set relatively low at ~20Hz
Very simple code, so no hierarchy to speak of
Software is DONE!

4. Main Board
Largely interrupt-driven to increase event-handling capability
Needs not be high performance, so PIC32 clock rate is expected to be less than the 80MHz maximum
Have simple heartbeat program running on development board
