I’ve received my BrickPi last week and am still struggling to get a Lego motor work with any of the motor ports.
The RPi is working fine, Python is as well, and programs like the motor_test.py run without any software error. Only that there is no movement … The RPi is powered with 5V and the BrickPi with an 8xAA battery pack.
I’ve read various topics on motor issues, but they all end up with folks finally having solved the issue - but no final statement of how they managed to.
Is there any debug plan to follow to get to the root cause?
- Python modules must be of version <whatever>
- Voltage levels must be x V at pins xyz
- Any kind of further diagnosis program to run …
The RPi however seems to behave fine, as I can control a GPIO pin successfully with a Python program.
I do not own an oscilloscope so cannot measure directly the servo signals.
