DashX2 : Another Dashboard for GameDash

Hello,

After CarDashX, I wanted to make another dashboard aiming at more versatility and more eye-candy.
DashX2 was born. The concept is a bit different than CarDashX as there are no buttons; all configuration is done through console commands.
DashX2 offers the following display:

• RGB Leds for RPM indication: Choose any number of leds to drive. Choose the number of orange and red leds, and choose the RPM range to display in percentage related to max RPM (learned or configured)
• 4 7 segment digits display to show integer values.
• One 8x8 LED matrix to display gear

DashX2 offers the following configuration:

• Arduino uno/nano validated. Beside power, only 4 pins are needed. Gear and 7 segment modules are cascaded. Should you change the cascading order, just update the order in the code using the #define statements.

1. Pin 10 =TM1638 Data
2. Pin 11 =TM1638 CS
3. Pin 12 =TM1638 Clock
4. Pin 6 = RGB Leds

• RPM autolearn (on/off). RPM can be reset by adding a switch to ground to pin 6)
• Brightness control (stored in EEPROM)
• Choose number of orange and red leds (stored in EEPROM)
• Choose RPM range to display on LEDS. (ex: 1600 RPM max, with L=10 will light LEDS from 1440 to 1600) (stored in EEPROM)

Upon power-up you can see all modules auto-test:

The +5V provided by the arduino (even nano) is enough. No need to tweak the power supply as done with CarDashX.

Example using Project Cars:

Display is in order speed/position/RPM/fuel quantity

Wiring is extremely simple as you can see:




Usage using gamedash is simple. In the interface Startup put the init string you want, and in the interface output the values you want to display.
For ProjectCars, using the UDP plugin I made, the following settings work nicely :



Do not forget to put the math rules to convert values to integer !!

The code is available on github here: https://github.com/vthinsel/DashX2
The needed libraries, if you do not have them already are in the file DashX2_libraries.zip. Just unzip the content to your arduino/libraries folder as follow:


In case you want more/less RGB LEDS, just change the following line :

#define NUMPIXELS 24

And if you daisy-chain the 7 segment module and the gear indicator differently than my setup (gear matrix in the middle of the chain), change those lines accordingly:
#define SEGMODULE1 0
#define SEGMODULE2 2
#define GEARMODULE 1

That's about all you have to change in the code.

I just have to print a nice case and here we go !!

Woohhhh! This is one of the best i have seen.

Can you please list the hardware parts. Thank you.

Sorry for the posts but i am new here.
OK with the list, i thing i found them if i am right.

• 8x8 LED Dot Matrix MAX7219 Display Module for Arduino
• MAX7219 LED Dot Matrix 8 Digit Digital Tube Display Control Module For Arduino 3.3V 5V Microcontroller Serial Driver 7-segment
• NeoPixel Stick - 8 x 5050 RGB LED with Integrated Drivers

Hello !
It has been a long time I didn't post anything
Now, I'm back with my fully finished DashX2 that includes 8 4 digits LEDs (4 MAX 7219 modules in fact), and 3*8 RGB LEDS for RPM and a gear indicator.

Here is the display after boot:


The small box contains the arduino nano. The display box has a "dumb" 6 pin connector exposing all signals (3 for the cascaded MAX7219 and one for the RGB LED), so it can be re-used easily.

The github repo is updated with this latest version if you are interested.
Now, I'll review the Assetto Corsa plugin for console, as I hope that ACC will support UDP, and be backward compatible.

And the STL https://www.thingiverse.com/thing:4446229
I think I'm done with this project. Lets move onto load-cell on my T3PA
