Arduino Dashboard - Almost Complete.

We after alot of reading and looking around i decided i wanted a dashboard for my sim. Hmmm they are not cheap, wonder what else i can find out there?.
Well the Arduino Uno looks promising at only $40 for the microcontroller and a couple of buks for some leds.
A simple circuit was born.

Right then X - Sim side. Ok little more to it but it worked eventually and i can adjust the value where the last led lights on, so i can use this later to hook acouple of flashing (bright) LEDS to incicate the shift point, tried it with all my x-sim compatable games and yes all go. Just had to adjust the setting in x sim to gain full use of lights ie v8supercars need a rpm max of 8500 , TCL's Max was 6550, and so on.

Right that made me pretty happy but I really would love a gear indicator too. Hmmm, everyone else uses a 7 Seg Display, ok time to make a circuit to test first before combining it all into one. :uups: oops done that and added some shift lights too.

Re: Arduino Dashboard - WIP

Any pictures or video's of your project?

Re: Arduino Dashboard - WIP

sorry mate only a couple had to put project down to finish something more important.

When time comes back to me will update post fully.

Re: Arduino Dashboard - WIP

Hey there!

Great job done here so far. I have an Arduino Uno myself and use the same principles as you do except I do not use X-Sim.
I use rfactor-python scripting. My Led project includes a 7 segment display as well and that is hooked to Arduino also.
I am not too happy with the way the LEDS functions at the moment hence this post.
What I really need to know is how you set up X-Sim to push the data to the Arduino. I am really having problems trying to figure that out at the moment. I would appreciate it if you could maybe post some pics on your configuration of X-Sim. If you need some code regarding the 7 Seg part I will post all my code here if you want it. I suppose I could post some pics as well. Will do that later this evening.
Cheers :clap:

Re: Arduino Dashboard - WIP

ok rpm is easy one. 7 seg gets harder, all depends on ya wiring back to the shift register74hc595. Just set up a axis using gear and insert a serial.println in code and spy on the arduino with x sim connected to find the values x - sim is sending and once you capture there values insert them into you code.

Re: Arduino Dashboard - WIP

My std code for 7 seg - 6 speed with n and r.

not im using a blue 7 seg a little different on oin out than the red.

Re: Arduino Dashboard - WIP

This code works with my setup using rfactorpython

Re: Arduino Dashboard - WIP

Only problem I am having is setting up X - Sim correctly
I have no clue what to do. My brain is fried at the moment
I am able to see the values change in X-Sim once in rFactor.
3 screens is a bonus ;D
unfortunately nothing happens on my LEDs or 7 Seg
not sure where I am doing wrong here.

Re: Arduino Dashboard - WIP

yea couldnt get that one to work correctly and no support for rfactorpython.
So used it as a base then wrote new code to run in xsim and from vids i have seen for python, xsim does it better (faster response) but python plugin has the potential to provide alot more data to the arduino than xsim can.

Re: Arduino Dashboard - WIP

with python code running in arduino wont work mate been there. Have to write new code and set xsim up right. Will try to post combo code plus xsim setup to run a combined rpm and gear, have to test mine a bit to be sure i can successfully show someone else. Sorry for a delay. But if ya flash the rpm code to your card, just check the pin are the same value ie data,clock pins. Then set an axis to rpm and max of 8500 min 0 overwrite
then uso output is 8bit decimal. Send packet R~a01~ and the rpm leds should come alive same for gear but with send packet change the R to a G. And axis for gear is 6 to -1. But if adventurious combine the two and the whole board should come alive. Sorry not a complete tutorial, still writting another one this goes onto the bottom of the list to complete.

Re: Arduino Dashboard - WIP

Brilliant I could almost love you I know that the code is used for rfactorpyrhon and that it will not work with X-Sim. I have more ammunition to play with tonight so I will set X-Sim up axxordingly and hope for the best. The code you put here I use with X-Sim only problem I had was the setup of X-Sim. Now I will be able to use your advice and see if all works. If it does expect a post with some pics and maybe a video. Thanks mate.

Re: Arduino Dashboard - WIP

It does not work tho

Re: Arduino Dashboard - WIP

This is my circuit except I am substituting the greed LEDS for the 7 seg

Re: Arduino Dashboard - WIP

not sure what ya done. pic of circuit would help.
i moved on lcd up and running

Re: Arduino Dashboard - WIP

only thing i can see is the cap tying latch pin to gnd i dont use it. what is it for?

Re: Arduino Dashboard - WIP

Dont use the cap either on my board as for cicuit will need to make one up still. I basically copied the above one and substituted the leds for 7 seg. The pinouts of the 7 seg are easy to configure if you have a datasheet of a 7 seg.

Re: Arduino Dashboard - WIP

here is the circuit which I based everything on so far altho there is a fault on it the leds are incorrectly wired or named. The circuit does not work either but the wiring of the outputs to 7 seg are correct and combined with the previous attachment I built my board.
