I'm not sure what exact data and in what format you're getting from Modebus. I hope you've created custom the function to properly store data in the correct format before you print on the node-red debug console.

Hello good people

,

My name is Abdul, I was invited to this server by @32bitSaviour. I'm into everything web and work as a full-stack engineer. I'm super passionate about tech mentorship and volunteer at a non-profit called KamiLimu that aims to upskill university students. I am also very curious about open source. I haven't had the chance to contribute to it in a meaningful way but it is one of my short term goals at the moment.

ZacckOsiemo•11/13/24, 7:01 PM

Mambo! do you dabble in any embedded, IOT or electronics work? We would like to hear more about any of that

bijuice•11/13/24, 7:05 PM

No I do not but I would wanna try getting into low level programming. I feel like it's a part of my skillset that I could improve

@Ming @Phoenix, anyone else interested in helping us build out infrastructure to remote into platforms for dev purposes? The idea would be to create something that allows attendees of events apply the learnings on a remote node.

Me, @ke7c2mi and @ZacckOsiemo met yesterday to outline the general concept and are looknig for volunteers to help. If you are interested either like this, reply, or DM me.

Thx

Hi Devs, during my training about CNC machines manufacturing in Foshan, China. I encountered a few machines during test, I was so amazed by the amount of precision that they reached, I took this video and I would like to share it with you, tell me your thoughts

melta101•11/14/24, 4:49 AM

A person left the company and his stuffs were handed off to me

But here's the catch,
In my company, except for me and him, no one touches C/C++, so alot got dumped on me plus it's not embedded.

So here I am catching up to what all is done

melta101•11/14/24, 4:49 AM

Actually while digging
I found out that Google itself will help you to integrate it to the platform
As it's a part of GCP, and if the chip is one of the associated partners like Qualcomm and B&O, they provide sample+engg support
