thx

i try a simple diagram to block the ID:0x18FEBF03

even this not works wiht my cannyduo.

i dont now what can be wrong.

all the connectors are good can0 , can1

what i experience is that sometimes i get canbus faults. then if i trun of the power en start again the fault is gone. weird

My simple test diagram works.

Your simple test diagram not only works, it sends junk messages with ID 0x000 and no data to CAN1 every time it receives a message with ID 0x18FEF103 or 0x18FEB103 on CAN0.

This happens because you throw registers on the diagram following some logic of your own instead of studying the documentation.

My simple test diagram works.

With datalogger is see the bits is changend.

only the speedometer not use the new bits.

Is it nessecary that i put in the diagram that every Xms the candata send?

Diagram check is ok, simulator is ok.

Just because a diagram doesn't have formal errors doesn't mean it does exactly what you need. The simulator will help debug the logic, but not the interaction with the Firmware drivers. Please read this topic carefully: https://cannylogic.com/docs/cannylab/si … escription

Exactly as I told you before:

And regarding this:

Where is the data on which you made this conclusion?  As I told you before:

Taking ready-made examples and modifying them to solve your problems is a good way to learn a new product.
However, this is only true if you have read the documentation beforehand and understand what exactly you are changing and what effect these changes will have.
A necessary addition to this method is repeated analysis and rechecking of the modifications made, as well as constant monitoring of the operation of the modified example in hardware after each modification using measuring instruments, data loggers, etc.
This way you will be able to observe what effects your changes lead to, even if you did not read the documentation carefully enough or made a mistake when changing the example.
The most useless thing you can do in terms of gaining new knowledge is to ask someone else to do all this work for you.
If your goal is not to learn how to work with controllers, measuring devices and documentation, but to get a ready-made working circuit, then all I can advise you is to create a new topic here: https://forum.cannylogic.com/viewforum.php?id=11  and wait for a response if someone answers you.

And yes, you made a mistake, at least here:

Yes my goal is to learn more of controllers. If this controller works , i wil need more controllers.
wat i d ont  understand is how to see the faults in my diagram that i make. Diagram check is ok, simulator is ok.
I change the fault from 0x800F to 0x8008. But still the bytes that i want to change not change.
I try to learn from the faults that i make :-)

And yes, you made a mistake, at least here:

I find this map on the russian forum.

The map is to change the speedometer with modify bit D1:D0.

Can you control of this can work?

Why? This is completely wrong.

What is wrong?
d' ont i have to use the "Can1 request to send" ?
To send the modify bits to Can1?

In my previous map the output was "Green light",so i think no data will be send to Can1.

D0:D1 are the value that i want to change. (speedometer)

i dit 1 correction, green light to can1 request to send.

Why? This is completely wrong.

What Bit?

I have to learn mutch more.

i dit 1 correction, green light to can1 request to send.

if my diagram i made is now correct then =

canid: 0x18FEF103 (extended format)

Change value D1:D0 to 20 (Dec)

Send to Can 1

-Do i have to change Bit?

Please see the attachment for the diagram, slightly corrected to my taste.

Please check that you have connected CAN0 to the source of the original messages and CAN1 to the receiver of the modified messages. Check that the CAN termination is correct. If after all it doesn’t work as it should, then message logs from both CAN interfaces will be required for further diagnostic.

i try to understand the logic in building of a diagram.

I think that I mis somme important settings in my diagram.

maybe i have to search for "Canlogic for dummys" :-)

can id: 0x18FEF103 - extended format.

IDH=18FE
IDL=F103
ERL=8008

This is finally correct register's values for some applications. However, you did not indicate the full names of the registers.

You did not attach a diagram and didn't ask a specific question. I just can’t "check" whatever that means because I don’t know what “wrong” means in your case.
