Motor control
The first page is a motor control page where you can check that the motors are spinning as expected. Enable control by checking the “Enable motor control” checkbox.
This control overrides the software arming.
You can either spin the motors separately or all motors at the same time with the “Master speed” slider.
NOTE: Be careful to not ramp the speed up so high that the drone takes off or flips.
Write settings to the ESCs
Click the “Read Settings” button. The settings read from the ESCs will now be displayed.
Be aware that setting other settings than the recommended is done at you own risk, make sure you know what you are doing before attempting to change these.
The default setting configuration we have written to the ESCs at production are;
for our default settings.
To write the setting to the ESCs press the “Write settings” button. This will write all the settings shown in the GUI to the ESCs.
NOTE if you push “reset to default” these settigns are not our default settings, but the ones specified by the esc-configurator website.
Flash the ESCs
To flash the ESCs press the “Flash Firmware to this ESC”.
You can choose to flash either a standard off-the-shelf FW like Bluejay or BLHEli_S or a custom FW.
We have our own fork of Bluejay which you can find here; https://github.com/bitcraze/bluejay
NOTE: If you use a FW that has a PWM Frequency setting please note that running on 24kHz causes unstable flight behaviour
