    <value targetId="37" offset="2" length="4" units="bit" conversion="V>>4"></value> <!-- RPM -->

Is this line correct for the frame? 0x0c9

If you just want byte four of the frame in its entirety then targetId=“37” offset=“4” length=“1”

The units=“bit” will select the least significant single bit and the conversion you have is shifting the result 4 bits to the right; neither seem relevant to an RPM value

Thank you for your quick response. So, how can the frame be written in the attached video
0x0c9:

mmain · February 28, 2025, 11:16am

The frame is 8 bytes wide (0-7), and you have highlighted byte 4 in the video, but is this what you want to interpret as RPM?

xj8 · February 28, 2025, 11:19am

Yes, it is exactly the RPM bit

xj8 · February 28, 2025, 11:22am

My problem is I want to understand how to write variables such as RPM, fuel level and battery level

What I have given you should give you the required value, no need for units but you may need some conversion with only an 8 bit value representing yours cars likely RPM range ~ 0-8000

Thank you, dear. Can you write me the frames attached to the video? I would be very grateful to you so that I can try it out
It took a lot of time

and thanks again

ox0c9 : rpm
0x0fc: speed
0x12d: tps

I am not sure what you think is not working with the xml file, it merely aligns the selected canbus data with RealDash. I am not convinced RPM will ever be a single byte (8 bit) value. You obviously think you have the correct byte for RPM, but it is probably worth changing length=“2” so you get the next byte and hence a 16 bit value.

I also suggest you use Debug Data View to see what values are being read by RealDash, and attach screenshots of where to find this.
