I got my BrickPi yesterday and have managed to get it setup with my WIPI WIFI dongle. Connecting with putty works well though I can’t seem to connect with VNC Viewer (connect: Connection Refused (10061)). But I can get by with putty for now.
I have successfully downloaded the github C files and have successfully compiled “LEGO - Motor Test.c” (suggestion for next time: skip the spaces in the filenames).
I hooked up my 2 LEGO motors to my BrickPi motor ports A and B. It is tricky to get the motor cables to click in (harder than with an NXT brick, and the BrickPi board does wiggle a bunch when I do this, but with care they can be clicked in).
I see three different results depending on how I’m powering the BrickPi.
If I power it only from a 9V battery, I get the messages
and the program exits without any movement from the motors.
If I power it only from the Pi’s external miniUSB connector with an external wall power source, I get the error messages shown in the attachment and the motors don’t move.
If I power it with BOTH the 9V battery AND the Pi’s external miniUSB connector power source, I get the errors messages but the motors do move (yeah!).
So, what are the error messages? Do I need to use 6 high current AA batteries instead of a 9V battery to get it to work better? I couldn’t find any information online regarding powering the BrickPi with different options and what the advantages and disadvantages might be. The BrickPi needs to be able to run off a battery with WIFI for it to be useful (and I want to add a webcam too). I’m guessing I’m doing something wrong?
Thanks for any advice anybody else can provide.
