It was built with the following requirements in mind:
- Fast MCU, plenty of GPIO, Wifi & BLE, relatively low power (we chose the ESP-32 Microcontroller)
- Modular code design
- Attitude stabilisation (Pitch/Yaw) using either canards fins and/or Thrust Vectoring Control (TVC) and soon, Reaction Wheel (for roll control).
- Up to 4 servos connections independently controlled using PID loops.
- Altitude / Apogee detection using BMP-280 and MPU-6050 for Gyro/Axcel.
- 4 pyros channels (using mosfets) for deployment of recovery systems and stage separation.
- Must be able to log as much information from the flight passible.
- On board 64Mb Flash memory + optional SD Card for data logging.
- Battery voltage monitoring (regulated from 7~12v down to 5v and 3.3v).
- GPS capability (not used yet)
-
- WIFI bi-directional communication for parameters configuration and pre-flight systems tests.
- And the all important flashing RGB Led and Piezzo Buzzer :)
A Web Bluetooth app is used to configure the MORGAN flight computer. Its project page is https://github.com/intensite/morgan-app
The Bluetooth portion has been deprecated for now had it had stability problems that was crashing the flight computer. The code was commented out for future rework if necessary.
The project was moved/renamed from https://github.com/intensite/rocketcontrol
The main reason was a change of developpment environment. The project is now developped using platformIO wich greatly speedup compile times and library management. The old code will stay here to preserve the commit history.
