Software
The software repo is here. The board is programmed using Platform IO in VS code.
Setup
Setup instructions assume board is just being used for data logging (TODO: add instructions to use as flight computer)
- Ensure the board is not contacting any metal surfaces
- Check that the internal power header pins aren't connected (see photo)
- Insert SD card into Teensy
- Connect the Teensy to a computer via USB
- Upload firmware using Platform IO
- Data should be logging, and serial data being sent to the computer. Open the Serial monitor to check that everything is working.
- Unplug the teensy from the computer. Verify the SD card has data written to it by plugging it into a computer and opening the file.
- Put the SD card back into the Teensy (it's okay to leave the program, a new program file is created every time it is turned on)
- Insert the internal power header jumper cap to have the Teensy powered by the battery
- Screw a connector into the power in port
- Verify polarity! Red on top, GND on bottom
- (Optionally) add any arming circuitry to the power port connector, such as a magswitch or toggle switch
- Plug the battery in and turn on. Unplug immediately if the light does not turn on and buzzer doesn't beep
- Teensy should be in fully operational data logging state. It will have slow chirps indicating that it's logging data, and a green flashing LED. Fast beeps and a red LED indicate an error. If that happens, unplug, remove the internal power header jumper cap, and plug in with USB to view serial data.
Pre-Flight Checklist
Packing list:
- Board
- JST Connector
- Batteries
- Battery charger
