FRDM-Copter is an attempt to build firmware for mbed based multicopter running on FRDM boards from Freescale.
Dependencies: FXAS21000 FXOS8700Q PID mbed-dsp mbed-rtos mbed
FRDM-Copter
Hardware
So far the following boards are used:
In addition I am planning on using:
- FRDM-CR20A 2.4Ghz module for communication with Frsky Taranis X9D+
Implementation
I decided to use mbed platform as it allows easy CMSIS-DAP debugging and firmware can be easily ported to other mbed enabled devices in future.
Phase 1
Sensor fusion will be implemented and estimated orientation plotted over blue-tooth in the Android application.
Phase 2
PID controller will be used to maintain orientation and control the motors using PWM channels, tuning will be possible in the Android application.
Phase 3
Controll will be implemented with CR20A 2.4Ghz module for use with Frsky Taranis.
Phase 4
All schematics will be transferred to KiCad on a single board.
