Have a Raspberry PI B 2, installed the latest image (2015.03.20_Dexter_Industries_wheezy) and installed the setup.py and made the firmware update (1.2.2). The output work (testet for LED and really). But not one of all my sensors work (ultrasonic, light, temperature, sound). Debuting flag is on. The output is always the same:
IOError
Error
IOError
Error …
Hope you can help me with some advise. Thank you!
Hey tba6441, sorry to hear about this. Can you setup one of the sensors, maybe the temperature sensor since it’s an easy one, and take a picture of your setup and post it?
Dear John
Thank you for your fast answer. Please find the attached pictures.
Hey,
Can you run sudo i2cdetect -y 1 and post what you see here.

Dear Karan
Please find the attachment. Thank you!
Hey,
Can you connect the temperature sensor to port A0 and run the grove_analog_read.py with port as 0 and 1 and post what you get here.

Dear Karan, please find the pic.
Hey,
It does look like that your GrovePi+ is not working properly for some reason and I am not sure why.
Can you contact us through our contact page, under “General Questions and Feedback”http://www.dexterindustries.com/site/?page_id=65 and we’ll send you a replacement board ASAP. Can you just add a link to this forum post so that it easier for us to track the replacement.
Sorry for all the troubles.

Dear Karan
Thank you very much for your help. I have already sent the message.
Hi. I have the same problem. Do you think that it is board problem?
Hey bastiao,
Can you describe a bit more about the problem that you are facing and what all have you tried.

Hi, I have the same problem too.
The output work (testet for LED and really). But not one of all my sensors work (ultrasonic, light, temperature, sound).
I have installed the setup.py and made the firmware update (1.2.2)
“sudo i2cdetect -y 1” give 04
Thank you

Hey Thorgrimm,
Can you try the firmware version 1.1 from here: https://github.com/DexterInd/GrovePi/tree/master/Firmware . Just run v1.1 and see if that works. What is the usual output when you run the programs for the sensor. Can you post a picture of your setup along with the code and the output that you got.
Thanks,
Karan

GrovePi has firmware version:
Traceback (most recent call last):
File “grove_script.py”, line 3, in <module>
print “GrovePi has firmware version:”, grovepi.version()
File “/home/pi/Desktop/FIRMWARE/grovepi.py”, line 218, in version
return “%s.%s.%s” % (number[1], number[2], number[3])

Grove Pi is broken ?
Thanks,
I’m having the same problem as this. I have managed to get the LED blink test to work by upgrading the firmware but no sensors on the board are working. Is there a resolution to this?
Hey jbb352,
Can you describe more about the problem that you are facing. What sensors have you tries and what output did you get. Also it would be great if you could attach some pictures of the the sensors connected to the GrovePi.

Have the same problem with my GrovePi 
Though digital relay works ok, but all other stuff doesn’t
light sensor sends values after like a hundred errors
looks like:

Hey askimer,
Can you describe a bit more about the problem that you are facing. What sensors have you tried on which ports . Also it would be great if you could attach some pictures of the the sensors connected to the GrovePi. Can you run this: https://github.com/DexterInd/GrovePi/blob/master/Software/Python/grove_firmware_version_check.py and let us know what you get.
-Karan
Hey,
We were able to replicate the problem at our end and it looks like it was a problem with the fuses which were burnt on the GrovePi. Can you try running the script that I have attached (Make the script executable sudo chmod +x grove_setup.txt and run it sudo ./grove_setup.txt.) and let us know if the problem goes away for you.
