The I2C Ports are not working on a couple of GOPIGO3s in my class. I tried connecting the distance sensor, line follower, and TPH sensor with no luck. Bloxter says it is "Looking for. . . " I have no problem with the other robots.
Can you tell us what version of Bloxter are you running on those robots that work and those that have issues with the I2C port?
I’m using the same version for both (are there different versions?) with the latest Dexter OS 1.3. When I connect to the robot it takes me to
mygopigo.com/Bloxter. I also tried Advanced Bloxter and it didn’t work as well.
I thought may be the red board got shorted out but the wheels, actuators and media all work.
We have a higher version of DexterOS (> 1.3.0) and that’s 1.3.1. I’m bringing @cleoqc into this discussion to see if this can be caused by the front-end stuff of DexterOS or if it’s the hardware the problem.
My gut tells me this revolves around the firmware of the GoPiGo3 and the hardware itself and not DexterOS itself.
Can you run a test for me, please?
Code in Python, double-click
GoPiGo_Python_Examples, then double click
Scroll down until you find
Read_Info.py and single click that one. Once it loads in the editor, click
run right above the editor.
You’ll get printed info in a console at the bottom of your screen.
I’m mostly interested in the firmware version.
And here is a second test , please
If you scroll up in the list of sample programs, you will find
What happens when you run this one (with the distance sensor connected)
(You will need to hit Ctrl-C to stop that program)
On the first test:
Hardware version 3.x.x
Firmware version 1.0.0
These are the same as the working robots
On the second test;
AttributeError: class DistanceSensor has no attribute ‘init’
I burned the latest version of the Dexter OS onto a reformatted microSD drive and it appears to have solved the problem for at least one robot. Will get you a final verdict after I apply this fix on the other robots. I’m wondering if something happened after repeated updates of the OS from the USB drive.
