Cooling Board Objectives
To Do
- -
Done
- Propeller USB connection
- Flowmeter reading processing
- Propeller sonar processing
- Power connector (12, 5VCC)
Cooling Board Results
No catastrophic errors.
Bug List
- USB signal (D+ and D-) is flipped, we are fixing the problem by rewiring the legs of the USB B connector. We fixed the Altium file so that this is not needed in the future.
The picture below is for the sensor board but since the originator of the problem is the Propstick, the solution is the same for all peripheral (cooling, sensor, and motor board).

Wrote Frequency monitoring code for flowmeter. We blow on the tubes to simulate different flows.
