Speedcontrolled Fans integrated in TM1638 Dash

Hello Fellas,

i´m using this simple Dashboard and im realy happy with it.
i want 2 use 1 or 2 rc-impellas with a brushless ESC.
why impellas?
the response characteristic of PC-Fans is to low, and all parts are there.

so i try since 2 days to get the speed data to the Servo-Operations.
either the dash or the servo works, together it won´t work.
is anybody here who can help me with the ard-code based on sora´s code?


thx and have a nice day

We have this already written. ? You need to add a control to take the speed and turn it into a PWM value. And drive the pin required. Which code have you tempted to use, I can fix easily. A little more details and I can provide a working code for you.
Are these driven like a servo a pulse(PWM) from one pin, if so easy add on.

P.s I wrote my own as converting to hex and back causes errors in value as shown in his pic, speed is out by a bit.

thx earobbie for the fast answer,

yes the ESC works like a Servo.
it is allready written, ohh ok, where can i find it?
Sora´s code is no must for me. i found and use it

Its an old code meant for another software, I actually wrote part of it 2 years ago before leaving the site.

My code http://www.xsimulator.net/community/threads/tm1638-multiply-page-display-with-gamedash.5003/
I can add wind control to this if you so require.

THX

and how could i include the servo operations?

Code:

//
int Speed;
int Gear;
int Rpm;
int RpmLeds;
int RpmMax = 000;

int buttonCheck = 1;
int bufferArray[12];
////////////////////////////////////////////////////
#include <Servo.h>
Servo windservo;
int valwsv = 0;
////////////////////////////////////////////////////

#include <TM1638.h>

TM1638 module(5, 4, 3);

void setup(){

  Serial.begin(57600);
// initialize the screen:
    module.clearDisplay();              //clears the display
    String name = "DASH";           //sets a custom Label
    module.setDisplayToString(name);    //prints the Label
    delay(3000);                        //small delay 3 sec
    ////////////////////////////////////////////////////
   windservo.attach(9);
   ////////////////////////////////////////////////////
}

is this the correct beginning/way?
now i see i`m a absolute flake in programming ardu

As promised.
Tm Board set to pins as above, esc pin set to D9 on the Ard, instructions in code to change it.
Ok the RpmMax is set at the start but can be adjusted when in game on the fly by holding max rpm and pressing button 3 on the TM.
And maxSpeed is set to 300 in code but if car goes past 300 it will increase that till the Ard is reset. This is used to map speed from 0 to 300 - 0 to 255 meaning at 0 , fan should not spin and at 300+ it will be flat out. This is all changeable in code, ignore all the value "//" (rem out) this are other values I use so the dashboard can have many pages of information at a touch of a button.

Many THX earobbie


i test the code and sometimes the dash works and then not, the servo* ALWAYS twitches arround???
*test with a servo 2 see optical what happens
The dash, if it works, only works with these output rules:
IRACING:
Dash1 - Speed
PAD 3 0

Dash2 - RPM
PAD 5 0

Dash3 - Gear
PAD 1 0

strangely, in reverse gear (the "r" is not shown on dash, it`s blank) the kmh/rpm and the LED´s working nearly perfekt, and with luck, in 1 from 10 cases, then in forward direktion as well.

when it works the Speedo shows around 3-5 km/h less speed then iracing.

I tried baut rates from 9600 - 115200 - doesn`t change anythink



so, now its time to go to bed

hello,

Update: i test the dash and servo in office,
servo and dash works now, but only in reverse driving

i think i get t to handle on.

thx again to earobbie

No worries , you need to investigate what iracing is sending the to the GameDash.
Most games send a -1 or 255 for reverse so to use my code you need to include " replace -1 9" or "replace 255 9"
Basiclly it will as says replace the incoming figure with the figure you have choosen and outputs that only.
Code is written for 57600.

With the different speed that actually coming from the plugin, I cant fix that as I font have the source for the plugin, still waiting for that to be updated. One day.

I will load Iracing later tonight and check what values it uses and produces, lol I haven't tested the dash on IRacing. Mainly use it for Race07 and AC.

Robbie you are my Hero

now i works............. with the following Output-Rules

IRACING:
Dash1 - Speed
PAD 3 0

Dash2 - RPM
replace -1 0
Pad 5 0

Dash3 - Gear
replace -1 9
Pad 1 0

many THX

ok now i see it works great if i programmed the ardu before.
if i unpplug & plug the ardu only the label comes up & nothing.........
but that doesn´t matter, i will programm the ardu bevore every iracing-session

You have found the bug that's was bothering me too, a quick fix you can enter in the shutdown for the Game Dash
R00000G0S000 at 20ms this should reset the gauges back to 0. But as I have found certain games on exit spit out some random figures , something I need to investigate more, looks like Iracing is now on the growing list, Assetto also sends a big random rpm value when it exist, a small catch was added to code for the ard, but still testing it and need to check that it is the same case for Iracing.

For now if the Ard looks like it has hung, you can close the gamedash, and close the game manager and then reset the Ard.
Restart the GameDash first then restart the GameManager , sorry for this inconvenience as the GameDash is still really a beta app avail to everybody to play with, I feel the outputs from some of the games that we have set dash out for need some more refining so it doesn't spit out these random large figures.

Maybe a slight change of code in the Ard will sort the issue too. Im currently working on a add on card for analog dash building.
The Porsche dash was a success and a Ford dash is nearly completed and it and code is nearly ready for show.
More to come.
