lin injector do not work at all

[wchpikus]

Hi
This is my first post here, and i like to write what i like to do.
I like to filter commands in volvo car (disable some function).
I build injector, but it not responses for lin frame.
I have only one to 3 sek blink error message led.
Master connect to slave, slave to master.
Better, i do not have any data on uart..
Could you tell me what can i check first?
Atmega328p.upladed hex from githup, without any changes..
Btw..it i setup fusebits as on github, connection to uc is not avaible..(setup clock as internal?)
Regards

You are trying to inject Porsche LIN commands to Volvo, big chances that is not going to work.

You should use analyser to check the commands your slave is sending and then modify source to inject same commands to master

Hehe..sure..
But, why any info i do not have on debug?
I saw in code massage like "waiting", but nothing send to uart..
Ok, i have analizer and can connect to rx pin behind lin transiver.
Do you have any example where i have to put lin frame (data) to analize?
I read about time to response, it us enough to analize and pass or not?
Tnx for response

There is a python script to help analyse the response from the board, try setting that up and check what the output is.
