Byte 4 & 5 = RPM
Engine RPM
Hex 0D34 = 3380
3380/ 4 = 845 RPM
EXCEL / Arduino Forlmula = ((Byte[5] * 256) + Byte[4] ) / 4
Example Above = (( 13*256 ) + 52 ) / 4 = 845 RPM
the byte format is intel hex but i have searched high and low to figure out how to add this to a dbc and came up empty handed.
any help or links that explain how to accomplish this would be epic!
also are there any tricks to figuring out how to decode such messages. i have a list pulled from a tool32 .prg file with all the major can ids and descriptions that will leave alot less needles in the haystack once all those are figured out
i can't read the text as it's really light blue on a white background.
