Dragonfruit Team Meeting #4 - September 19, 2016
Attended: Keane, Kevin, Tyler, Kaeo
Updates
- Spoke with Garret on Skype about the board
- Check the power supply with the ammeter to figure out the current input to the circuit
- check voltage across the black capacitors in parallel without the solar panel
- LED on sensor board for firmware to debug
- Compare notes with cranberry on the sensor boards
- ask kenny about using a wheatstone bridge to modify the battery and solar panel voltage instead of a voltage divider. for the ADC.
- website looks at the battery voltage - ask kenny.
- slower clock and take out the 5V boost converter (clock cannot run without 5V)
- make sure the sensors can all handle 3.3V
- make sure all the parts can run on 3.3V
Problems
- N/A
Next Steps
- Work towards implementing the board with a slower clock and no 5V voltage regulator
- Slower processing speed
- Less power consumption
- Able to gather data at least
- Look at data sheets to be sure parts can operate on a 8MHz clock and 3.3V
- Look into how to remove the 5V regulator so that the board will still work
- Code the currently working board with Firmware
- currently planning to deploy the board that is already working, however this board will not last long without sun
- come up with solutions to allow the speed without the power consumption
Reminders
- Deployment early October (October 2nd), so try to make current board operational.
