I just updated the module You will need to upgrade to master if you want to test the yet-to-be released code. Please let me know if it works if you do test.

Please tell me what to do now : a lot of errors appear with the atlas ph sensor, it has worked without errors before i set up mycodo the 2.nd

Ahh, yes. I forgot that I changed that part myself. 09 is not working with manual buttons. In the new master you should be able to select the new ā€œstandardā€ grove 1.0 output. This should work and also have the ability to change i2c address on the device. You can delete all the 0x test versions then

95

After updating to master : i have a lot of issues and i dont know why,
ph shows some values, but stopped after a while. Is there an issue with the input modul ?
How can i check this ?

96

You would be better off, if you make a separate forum post for each issue.

As for the Grove 1.0 module, it looks like Kyle havenā€™t updated it with the latest changes yet. So it wont work as of now. Maybe use the 07 for now and change it in the future, when there is a stable release.

Please only test the version on Github (acquired by upgrading to master), as this is the one Iā€™m actively developing. Delete all other test modules you may have imported.

Agreed

Just pushed a fix to check if amount is None. Upgrade to master and see if it works. Thanks.

ok, i have tried the last motordriver with ability to change i2c adress
changing i2c is successfull, motors dont turn
now going back to Version 7
both boards are working now with different i2c adresse

here is the log:

Remember you need to upgrade to master to get the latest code. The error you pasted is the same one as you previously posted and indicates you did not upgrade.

You can see in your error, your line 311 references a line of code that is different from what currently exists on the master branch:

Hi Kyle, sorry I just saw this. As far as I know it is the same as from the old forum, so if youā€™ve made updates we should go with that new version. Unfortunately right now I donā€™t have my motors set up to test them easily. When I get them back up again I will run tests and give feedback. Glad to see this is making it into a release
