This firmware was written using Platform.io, an extension to vscode for microcontrollers programming, please use it to be able to compile and upload the code properly.

This reposotory also uses git submodules to point to the require libraries needed, please clone this repo, do not download it, then run the following:

git submodule init
git submodule update

The firmware at the moment successfuly does the folllwing:

• Initlizie and read sensors:
  • ADXL357 accelerometer
  • MS5611 barometer
  • Generic NMEA GPS
• Write readings to builtin SD card
• Transmit the collected data after encoding

The following tasks need to be done:

• For the GPS:

  • look into GPS modules specs similar to that of the featherWeight specifically the Cold & Warm Starts (due to the issue of it shutting off and losing lock when rocket exceeds the COCOM limits)
  • Make the GPS update at 10 Hz

• Handle sensor initalization errors

• Order a PCB and field test the system

• Simulate power transients with Eagle/Kicad

• rfd900+ frequency switching

• Bay thermodynamics(for two stage)

• Improve the way the rocket descends and lands(dynamic flight stability)
