    Here is a good example of how to use the dash feature found in SimTools v3.
    (Special thanks to @early_m for helping with this post!)

    Below you will find a wiring diagram, a sketch for an Arduino, and instructions to turn an addressable led strip into a RPM bar. The Sketch is setup to use a WS2812B led strip, but anything compatible with the FastLED Arduino api will work as well.



    Here is the led strip wiring diagram:

    RPM Arduino Sketch:
    RPM.zip

    Once the file is opened, be sure to set the settings below.
    - the number of led's in your led strip.
    - when color#2 starts
    - when color#3 starts
    - max brightness of your led strip (255 is max)
    - the pin number for the led strip to connect to.

    And you can edit the 3 colors you want to use in your strip here
    (It's RGB values where 255 is max and 0 if off)

    Then upload it to the Arduino you are golden!

    SimTools v3 setup.
    Go to the interface settings and connect your new led bar

    Then go to the edits for rpm and set the command GetBits 0 9000 8 b, where 9000 is the max rpm you want to use for the profile.

    And lastly, tell SimTools what to send for output

    That's it, now run the game and enjoy!

    What values do I have to change ?

    I have led strip with 72 leds, Using RaceRoom game. When I start the game 12 leds (all green) lit up. More rpm the blue light up (20 leds are green, and after 20 blue leds lit up and then red lit-up max 6 red leds.
    so the maximum number of leds that lit up is 46 while I ave 72 leds :)

    I want default 3 leds on, then with higher rpm 25 green on, than 30 blue and than 17 red when rpm is max.

    thanks for any help on this

    Hans

    If you have set the proper settings in the sketch here:
    upload_2023-11-18_10-47-15.png
    if you still don't get all led's on, take a look at the Hi/Low settings for rpm for the game.
    My guess is the Hi values is to Hi is all.
    Let me know how it goes buddy!

    thanks for the tip

    I have Race Room Experience and used this settings: Getbits 1550 5500 8 b. The ledstrip works great now. By default 1 led is on and with full RPM all 72 leds lit up.

    Does the sketch go with the dof 2 sketch?

    You would use another Arduino for this, not combine it with the motion side of things, if that is the question?

    Yes, my question would be this, do I have to use another Arduino? Another question is how is the acceleration signal recognized?

    From what I understand, the signal is recognized by the serial port.

    Yes, as Dash and Motion interfaces are separate.

    We are using the RPM output from the Dash section.
