Hi.
This code:
import grovepi3
moisture = 0 #Moisture Sensor in A0
grovepi3.pinMode(moisture,"INPUT")
grovepi3.analogRead(moisture)
Results in this error:
grovepi3.analogRead(moisture)
File "/usr/local/lib/python2.7/dist-packages/grovepi3-0.0.0-py2.7.egg/grovepi3.py", line 165, in analogRead
IOError: [Errno 121] Remote I/O error
Analogous code with the same sensor on the other grove pi (default configured (4)) works ok without error.
Any clues?
Thanks.
Hi @wdjong,
I donāt think we have a GrovePi3 board yet.
So, can you tell us what itās grovepi3 module made of?
Iām asking this because our module is called grovepi.
Also, please tells the following:
Are you using Raspbian For Robots or have you installed all these on a fresh Jessie image?
How is the GrovePi board connected to your Raspberry Pi - a photo should do the job.
Can you run the GrovePi's troubleshooter and post here the output file?
Thank you!
Hi Robert,
My friend wdjong has been helping me with troubleshooting on my project
So I am responding to your request for information regarding the above issue
Iāve updated the firmware on my GrovePi board since Iām using multiple boards to I2C address 03
Iāve been using the grovepi3 for addressing the ports on this board as per the DexterInd site
https://www.dexterindustries.com/GrovePi/programming/using-multiple-grovepis-together/
However, the analog ports A0//1/2 are giving me errors.
The digital and I2C ports seem to be fine.
As instructed Iāve run the troubleshooting complete_test.sh & generated the attached log.txt fyi
Iāve also attached an image of my setup.
I have four ModMyPi relay boards connected directly to my RaspberryPi board and then connect my Grove boards via a ribbon cable

Hi @Greg_Norvill,
Could you use one GrovePi at a time and check each of them (again, one at a time) if they are functional?
By dividing the test into smaller components, we can determine if thereās a hardware issue with one of the GrovePis.
So, basically, Iām suggesting you run the troubleshooter for each individual GrovePi and then post here the result.
By the way, I cannot see any photo of your setup.
Maybe you can take a look at your post and see where the photo was lost.
Thank you!
Thanks Robert,
I have run the complete_test.sh on both boards separately as suggested & generated log3 for the grovepi3 and log4 for the grovepi(default address 04)
Iāve attached an image of my setup with both boards stacked & connected to my RPi via a ribbon cable off the top of 4 ModMyPi relay boards which I;m using for outputs.
I noticed in the grovepi3 log that the āChecking for firmware versionā delivered an error. Does this mean the board is damaged & if so is it repairable.
Thanks Greg
PS Iāve included only 1 attachment as I get a post error
Hi @Greg_Norvill,
Iāve tested 2 GrovePis stacked together on a Raspberry Pi and it worked using the code youāve been having issues with.
I noticed in the grovepi3 log that the āChecking for firmware versionā delivered an error. Does this mean the board is damaged & if so is it repairable.
Your board is fine. The reason you got this message is because the firmware checker only checks at address 0x04 and not 0x03.
I think we should try something else:
The GrovePi that is found at address 0x04 (and which works with the code youāve shown us), please reflash it so that it points to address 0x03.
The GrovePi that is found at address 0x03 (and which doesnāt work with the code youāve provided), please reflash it so that it points to address 0x04.
By doing it so, we can rule out the hardware issue.
If the other board will fail at address 0x03, then it means the multi_grovepi_installer didnāt install correctly. In contrast, mine worked.
Thank you!
Robert, as requested I reflashed the GrovePi 03/04 boards as suggested.
I also set up the boards on an independent RPi without any of my ModMyPi relay boards to eliminate this component as well.
I ran the script below again with moisture sensors on A1 on both boards & got the attached error
Thanks G

Hi @Greg_Norvill,
Can you confirm me that in your āexperimentsā you switched the addresses of the GrovePis? Like the one that was at address 0x03 was changed to 0x04 and vice-versa for the other GrovePi board.
If this is what you did, then we can proceed to the next paragraphs.
It looks like the hardware is alright since now itās the other way around.
I think some step was missed at some point or something didnāt get through - I say this because my setup works and because your GrovePi boards are fine.
Hereās what I think we need to do:
Start clean again. Like flash another micro SD Card with Raspbian For Robots on it. Also, make sure to have the latest updates on Raspbian For Robots. Youāll need to use the DI Update tool (itās found on the Desktop) and update the GrovePi software.
Use the multi installer tutorial again, but walk-through it with more care. Tell us every step you did and how you did it.
The target is narrowing down the possibilities as much as we can.
Run i2cdetect -y 1 and tell us what you see.
Run the following code snippet (and then show us the output):
import grovepi
import grovepi3
try:
fw = grovepi.version()
except TypeError:
fw = 0
try:
fw3 = grovepi3.version()
except TypeError:
fw3 = 0
print("grovepi firmware check: {}".format(fw))
print("grovepi3 firmware check: {}".format(fw3))
Letās see what we get out of this.
Also, we appreciate a lot having lots of details posted on here.
Even details that might seem obvious to you, to some other it might not. I think the word Iām looking for is excruciating detail.
Thank you!
