@Gabriel would you be so kind to help out? Currently this is holding me back from adding a new feature which is a distance sensor mounted on the z axis and “hard” wired to the Raspbi…

Thanks very much, BR

Will pins D11, D6, A13, A14, or A15 work for your purposes?

23

Hey Gabriel, at the moment I only would need one analog in without pull up, but it might be good to “erase” another pull up on another analog in. Where they are located on the board does not matter for me…

Thanks!

Hi Gabriel,
I am confused. Are you referring to the pin names of the RAMPS board?https://forum.farmbot.org/uploads/default/original/2X/8/85f908df533914760951f5e799c5d1e14910eee8.jpg

Or are you referring to the Raspbi? If I look at the bindings, this is clearly referring to the Raspis GPIO?!

Please clarify… thanks in advance!

25

These are RAMPS/Arduino pins.

26

Thanks for clarification again, Gabriel!
Could you please check again if A15 is really not pulling up during the initialisation? I tried again with my distance sensor and as soon as I connect it to A15 it shows 5 V, before (disconnected from A15) it works flawlessly with a Voltmeter…

27

@Gabriel I really appreciate an answer as it seems that this is still not correctly configured in the initialisation of the firmware!

Thanks!

28

Those pins are not pulled up in software, but may have hardware pull-up resistors on the RAMPS board.

29

Hey @Gabriel any more information that you can provide would be really appreciated. At the moment I#ve got the bot indoors and I really like to solve and troubleshoot this problem before I need to put it out again in some weeks.

Would you be able to provide raspberry pi pins as an alternative input in the sequences?
How could I continue with this pull up resistor issue on the analog input pins of the RAMPS board?

Thanks in advance for your support!

Do you have access to the Arduino IDE? You can edit the change the pin mode for the pins you mentioned (D57 (A3), D58 (A4)) to INPUT and upload the modified firmware to the Arduino.

Hey Gabriel,

I do not have currently I would need some more support (if possible!) to advance in this direction.

I am exactly where I was mid-december but I thought you’d already implemented this change into the new FW as I read that in another thread… this is quite confusing. Would it be of a big effort for the FB team to include this change in a new FW release? Would be highly appreciated…!!!

32

@Gabriel would it be that much effort for you to edit the Arduino fw with one analogue pin to be not pulled up?

This is really essential for the distance sensor integration and I really don´t like to waste more days in getting into the Arduino fw whereas this would be maybe 10 mins. of your work. Moreover, I think many would be happy about it in future. Could you please support @roryaronson, Gabriel and I wasted together already many hours with the confusion created above…

Thanks, Best
Klim

To make the change in a release we will need to create a new firmware parameter, which will require changes throughout the entire stack. This will take some time. Making the change locally using the Arduino IDE as I’ve mentioned is by far the quickest option. I’d be happy to help with the process.

Thanks for the explanation Gabriel, I did not anticipate that much work on your side.
I will give it a try as soon as I am able to and let you know.

Are you currently planning on implementing it some time in future?
