You need to dig further. Does your documentation mention this error?

have anyone used CAN before? I was planning to make two devices talk via CAN and taking ADC read from one and writing that into pwm for controlling a servo on the other end
when it works fine Maybe I can Replace the ADC end with pure angular value then I can simulate the car steering workings

@Umesh Lokhande I think you have some CAN experience, no?

Yes, long back I wrote code to connect the CAN module from Sparkfun with Car's OBD port to read real live data. Here's a video https://www.linkedin.com/embed/feed/update/urn:li:ugcPost:6970616461518123008?compact=1

So what's your question @Undefined? Whether it's possible to simulate steering?

no I will implement it. is it relevant?

i’m at learning stage of CAN

You still asking, this could be done .

Hi Devs, today we visited manipulator robots factory, and the one that impressed me the most is this one welding robot with AI cameras wich detects the object that you wanna weld
What do you think about that

Is it something like the vision sensor/camera will interface to CPU and then data fed to the PLC for control or monitoring?

melta101•11/15/24, 9:05 AM

Actually the ones I had interacted with were non vision based
From what I understood
The CPU handled a GUI display from which you can program it visually like scratch programming, pushing the logic to the PLC, and the PLC to handle control related stuff

seems like a lot of work, I havent yet really looked into ladder logic I doubt i will but I would be keen to see how a PLC is programmer

melta101•11/15/24, 10:48 AM

i feel the same
instead if PLC, i would rather push myself to learn more about FPGAs

Can anyone help me regarding sampling CAN Tx/Rx Data with logic analyzer I am using a logic analyzer from aliexpres
I implemented the Can Connected Everything and When I monitor Data those are not the data I sent also
I tried bot transceiver they are giving same data so

It is Sure That Transceivers are working FIne Since Data is not Altered

gonna look into it

also I will program another stm on the other end so that I can verify everything better

Hello everyone,
I am trying to run Mongoose WS on my stm32h753zit6 board but every example they use NucleoH753ZI. They are using RMII mode but in my case I am using MII do I need to update something on library. I tested couple times with different implementations but still my ethernet does not assigning the IP. I am adding the serial log.

Can anybody did this before, can anyone help me about it?

that issue is fixed

segfaultdev.elf•11/15/24, 12:59 PM

Everything working fine

segfaultdev.elf•11/15/24, 1:00 PM

the issue was my breadboard XD

ZacckOsiemo•11/15/24, 1:00 PM

what was the issue

segfaultdev.elf•11/15/24, 1:00 PM

ZZacckOsiemo what was the issue

segfaultdev.elf•11/15/24, 1:00 PM

I was using an old breadboard of mine which was covered by dust

segfaultdev.elf•11/15/24, 1:00 PM

and the result you know already

segfaultdev.elf•11/15/24, 1:02 PM

Then I took my multimeter and checked the voltage of VCC and GND

segfaultdev.elf•11/15/24, 2:48 PM

So many things happens
I was using a STM31F411 since the First day of learning STM32 but today after creating project I saw it doesn't have any CAN Peripheral
then I soldered another Dev Board known As BluePIll
Then my breadboard started playing with me after fixing it my receiver end weren't jumping into ISR
but now everything is working perfectly

segfaultdev.elf•11/15/24, 2:49 PM

It was a long day

segfaultdev.elf•11/15/24, 2:50 PM

finally I am ready to take a break

Good shout, CAN will show an error when messages are not acknowledged, in default configurations that will cause the message to be sent repeatedly forever

TL;DR A CAN message must be received by at least one node or it is an error

I was checking then but it was mainly breadboard issue
