Simple Dash on Arduino+LCD with GameDash

Hi @TOPMO3

Tha ks for updating the pics. Was trying to qork out the wiring if the buttons. But this simplifies everything. Thanks again

Hi @TOPMO3

I have downloaded and installed the Plugin (iRacing_Plugin 1.0.5.2). when I load game dash and select the plugin from the menu nothing changes (dash Headings). I have attached screenshot below. I have tried uninstalling, patching, restarting PC. Just can't seem to get this to work. Have you got any ideas?

Hi @TerminalKaos !

Do you get "Game Running" in Game Manager when you start iRacing session?




If yes can you please check that you enabled Dash Output in Dash setting?

Hi @TOPMO3
Yes I do get game running as well as enabled the dash. I used the default 127.0.0.3 (I think) IP address beneth enable dash, as well as my PC IP address and still nothing.

All the dash code has been written into game dash also as per your screenshot.

@TerminalKaos if you are using one pc for simtools (game engine, game manager and GameDash ) IP should be 127.0.0.1
and then you have to configure game dash as described in first post. the only thing that probably be different is the COM port. you have to find which port your arduino is connected to.

Dear, managed to install all and upload the code.

I'm just using neostrip and i cant manage to get it work!

GameDASH read the data, but neopixel wont work....
My interface output : R<Dash2>G<Dash3>S<Dash1>F<Dash6>
TX Led turn on when i enter game, all ok.
If i reset the arduino when the car is in idle some leds turn on....

Wiring is:
GND to neopix GND...
Pin 10 direct toneopixDIN
and 5V to neopix 5V

Hi all,can i connect 2 arduinos to simtools at same time 1 for 2 dof and another one to dashboard ?

yes you can connect a 2nd arduino but you have to configure it in game dash app not in game engine as you have done for your 2 dof rig

Thanks ,time to start a upgrade to my playseat!!!!

Hi @TerminalKaos ,
I agreed with @insanegr , you should try 127.0.0.1 address.

Hi @Gabriel Vuelma Romanzini ,
hard to say without any diagnostics. At first look, it seems you have a trouble with communication between GameDash and Ard. If you need to reset your arduino, please restart GameDash also. And please double check your GameDash settings - ComPort and BitsPerSec.
Also for neostrip lights only you need only RPM data - ie R<DashXX>. or if you are using iRacing, then its better to use X<DashXX>.
And do you check neostrip itself? by flashing some sample code, just to check neostrip itself is working

@TOPMO3 this only works in iRacing? anyone have tryied other games like: Assetto Corsa or Project cars?

BTW Great joob...

Hi @mys3lf ,

Currently the sketch support these inputs:

// S - speed, km/h
// G - gear
// R - RPM
// F - Fuel, % * 10
// O - Oil, C * 10
// W - Water, C * 10
// U - Fuel, L * 10
// L - Lap
// X - Telemetry driven RPM LED blink, % of shift point (iRacing ShiftIndicatorPct)
// E - iRacing Engine Warnings

Only last two are iRacing only, other are universal. You need to check though what parameters can output a plugin for your game.

For example AC plugin support
"DashApp Data:
Speed [km/h], RPM, gear, shift light, fuel [lt], fuel [%], car model and track name."
so in AC you can use Speed [km/h], RPM, gear, fuel [lt], fuel [%] and can construct something like S<DashX>R<DashX>G<DashX>U<DashX>F<DashX>
Replace X DashX with corresponding dash

PCars unfortunately doesn't support Dash telemetry yet
"DashApp Data:
Additional values for instruments are feasible, yet not implemented."

Great Job!

@Donavan a 2 word reply this time, but at least it's a current thread congratulations!!

My Modded lcd+ 2 TM1638 working on Project Cars (PS4 Version)
I have 3 arduino boards running
One TM1638 plugged to Arduino Mega
Other TM1638 plugged to Arduino leonardo
and Lcd to arduino UNO Rev3
How that works?!?!?!?!?
Simple . I have 2 virtual machines in the some pc running each one are running the software Gameengine, Gamemanager and Gamedash thats the only way to make the 3 Gamemanager connect to PS4 port 5606
Thanks to @TOPMO3 for the project
soon i will post some video

May I ask how a speed from m/s to km/h as the output
Because the value of GameDash is m/s

Basic math. 1 hour = 3600 sec.
1m/s=3600m/h=3.6km/h
Simpler: there is a button on tm1638 to handle that

If this conversion unit, the value will be out of precision
Will there be other way?

Hi @it_pizy,
Sorry, maybe I don't understand your problem. If your game output speed in m/s but you want km/h, then you just need to multiply the value to 3.6 , as @vthinsel already stated.
For example If you have 11m/s, then it will be 39.6 km/h
If you use integer variable to hold values in a sketch, then you'll get 39km/h
but if you use for example long variable then you'll get honest 39.6 km/h

Keep in mind however that operations with floating points is hard for Arduino chip and they are slow because of this.
Do you really need this .1-.9 km/h? Its really hard to notice this difference in a race.
