4 byte ID corrupts on sending #19

Open bionicbone opened 2 years ago

I do not know if you are still supporting this... I hope so its the best I've seen!! Great job.

For Info: I have installed the canSniffer on arduino and its running in randomCAN mode. I have installed canDrive on Visual Studio running python 3.9 environment (3.8 not available for VS).

I notice some IDs are extended, like this (OK I dont undertstand why for now but I'm just getting started)

If we save to the decoded list the extended ID then this is OK

And we can resend the message and the extended ID is still correct on the bottom part of the screen but the resent message is logged incorrectly, only the last 3 of the ID are logged.

Also, when I resend the message I get this, only the last 3 of the ID are logged.

Hello, Thanks for the bug report. Its should be a simple fix, I believe it's just just a cropping issue im the GUI. I'll try to see if I'll have some this weekend to check, or you can try to check where that label is updated.

I did some analysis, so far I think it is being cropped in the Arduino either as part of the read or the wirte back.

Hello, I think I've found the issue, and pushed the fix into this branch: https://github.com/adamtheone/canDrive/tree/29bit_id_support The problem was a missing type casting in the arduino code. Can you test it pls? If it works, I'll merge the fix into the main branch.
