this is basically a compression algorithm

Usually when you want to get help you show what error it is you are facing, as it is your question is too broad to even tackle and likely people can't help.

the error is error:error

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?

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

melta101OP•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

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

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?

Everything working fine

segfaultdev.elf•11/15/24, 1:00 PM

the issue was my breadboard XD

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
