Motor Controller Interface
- Unable to consistently read motor speed temperature and temperature other data on from the motor CAN bus on system CAN
- Investigate MCU with two CAN controllersImprove SPI
- -CAN driverRedo MCP2515 driver and motor interface code
Waterproofing
- The thunderstorm was a concern in the beginning of the race
- Enclosures should be waterproofed
- Boards can be conformal coated
- Makes rework much more difficult
- The motor controller interface was damaged due to water

- We should try and design out as many non-leaded (QFN, DFN, etc) components as possible for ease of inspection and rework. Significant time was spent before and during FSGP to rework ICs such as the LTC6820 or the load switches on Power Distribution/Lights.
- Poor assembly (reflow/soldering) quality have plagued us since before ASC 2018. We need to either fix how we're doing things (play with stencil openings for example), train the team better to bring up higher quality boards, and functionally test every aspect of every board before putting it into the car. Most boards in the car are either reading inputs (driver controls, etc), or outputting power (lights, power distribution, etc), so perhaps we can set something up to test things?
Organization
- It was hard to keep track of where everything was
- It took 20-30 mins to pack and unpack everything when we had to move to the trailer park. How can we do better at this?
