I am quite far, (but not workings on the timing). i am working on making it UDP version independent, and to get the code working more efficiently.
Carflags 6 and 7 don't seem to work (ESP and TCS) and can't calculate the fuel lavel correctly.
now working with racestate and gamestate, but those bits also arn't what i am expecting of it.
am thinking of publishing the code, just to share and hopefully, to get some help/feedback.
after the post i stop the project... last week i was trying to use de UDP the ESP 32 and a CAN transeiver to use a car dashboard and it works =]
i can't find the esp, tcs and pit limit on the carflags.. ABS, ENGINE ACTIVE, ENGINE WARNING, LIGHTS is OK.
To calculate the fuel, you have to use the sFuelLevel [4 - use the same convertfloat as the speed] i'ts give you the % of fuel. mutiply by sFuelCapacity to have the Liters on the tank.
But i didn't sucess with laptime =[
if you want to email me, it is easier to help
