CarDashX : TM1638 sketch for GameDash

Salut
je ne trouve pas les lignes a changers dans le code pour la couleurs des leds et ne c'est pas si mon dash peu le faire , voici le modèle.

Hello
I do not find rows changed in the code for color LEDs and it's not so little do my dash, here the model.

@zigzag49

The code is changed, now you don't need to change the code, just press button number 5 - it will change the LEDs color.

Arfff mean that my dash is not compatible, I do not just change the color because instead of changing it turns off.
He'll have to change the LEDs directly wanted by green.
Thank you for your answer.

Hum. If I remember, this kind of TM1638 module is only one color for the LEDS. You need to be carefull with the descritption of the product. Mine comes from dx.com
As @prodigy says, you can defien how many leds you want to be red by pressing button 5.

That's what I thought, I'll change later.
Its also explains why at each race beginning, I was forced to press the 5 button to reset the 8 red LEDs because the last was always off.
Can you tell me or this may change in the code, to ensure that the 8 red LEDs light up either directly?
Thank you

C'est bien ce qu'il me semblai , je le changerai plus tard.
Sa explique aussi pourquoi a chaque debut de course , j'etait obliger d'appuyer sur le bouton 5 pour remettre les 8 leds rouge car la derniere était toujours éteinte.
Peut tu me dire ou cela peu ce changer dans le code , faire en sorte que les 8 leds rouge soit allumer directement?

Merci

It is here :

//Update LEDS
switch (rpmstyle) {
case 0:
rpmleds = map(carrpm, 0, rpmmax * 1.1, 0, 10); // distributes the rpm level to the 8 leds + 1 for shift change
break;
case 1:
rpmleds = map(carrpm, rpmmax * 0.75, rpmmax * 1.0, 0, 10); // display only 75%-100% RPM range for more accurate gear change
break;
}
//LED coloring: two bytes RED/GREEN
// 80 40 20 10 08 04 02 01
for (i = 0;i < rpmleds;i++) {
if (i>=(8-redleds) || rpmleds>=9)
{ //LED is red
leds = leds + (1 << i+8);
}
else
{ // LED is green
leds = leds + (1 << i);
}
#if defined DEBUG
Serial.print("LED value: ");
Serial.println(leds);
#endif
}

rpmleds contain the number of LEDs to light. then we choose the color based on the number of wanted red leds.
two bytes are needed : first (left) is for red leds, second (right) is for green leds.

If your display has only one colour, replace the for loop with this simpler one:
for (i = 0;i < rpmleds;i++) {
leds = leds + (1 << i+8);
leds = leds + (1 << i);
}

This will light everything possible (should produce some kind of orange in dual colour module)

You probably didnt install the lib correctly

TM1638 is a library file
https://www.arduino.cc/en/Guide/Libraries

I'm still using 1.6.5 Maybe you didnt choose the correct arduino platform. Maybe the bootlaoder is corrupted, or maybe a faulty clone. Can't help more on that. Sorry.

In Arduino IDE, under "Tools" menu, ensure that both the "Programmer" and "Board" are set correctly.

Sometimes, when you change the "Board" setting, it'll reset the "Programmer" setting, and then when you switch the "Board" back, it won't correctly update the "Programmer" portion. For most actual Arduino projects, "ArduinoISP" and "Arduino as ISP" are all but synonymous. Things get odd when dealing with "ARM" based Arduino projects, though.

I too use 1.6.5, as the newer one has bugs related to ARM devices such as ESP8266 that haven't yet been resolved. Might I recommend that if you continue to experience issues, you try backing off to 1.6.5, if for no other reason than to rule out some bugs that are in the newest version?

Thank you for your help all leds are ok but I'll have to buy the real TM1638 to enjoy.

Thank you for your code, I just wonder about the wires, If I well understand the TM1638 is pluged in pins 3, 4 and 5.
As library constructor declares TM1638(byte dataPin, byte clockPin, byte strobePin, boolean activateDisplay, byte intensity) so 3 is DI0, 4 is clock and 3 is strobe?

Edit: OK, get it to boot up (showing CardashX) but nothing in the game while pushing buttons... May I have miss any configuration?

Which game ? Which Gamedash settings ? Gamedash shows good values ?

Currently preparing a new version with I2C support. Took this opportunity to add ascii-art for pinout:

Edit: ASCII art not friendly with forum ....

I'm running the game dash with PCARS as game (well patched) game dash is showing values for dash #1 to #6 (almost).
The display shows parameters such speed multiplier, number leds activated or selected state for display but it seems it never write values to tm1638..

Check your serial output settings (port, speed) and the output settings


You can also use the arduino serial console and send data such as :

The command will be processed when a new one starts. For example, RPM will be updated on the module once a new command such as S will start
Serial data to start with max luminosity set (5), speed=95, RPM=4250, gear=2 (last caracter is to finish processing of RPM, can be anything except a digit)
Y5S95G2R4250R

If display is not updated using the console, it probably wont with the game launched either.

I tried to set values within the Game Dash interface to #1 interface but it did not updated the display. I'll try to send packets using arduino serial console at the end of the day to see if everything works as expected.
Thank yet for support

I tried to move the wires with my hand to be sure there are no false contacts but nothing happens.
Also, I tried to send packet through Arduino serial command and also nothing happens (the display still displays left & right selected state and parameters)..
Here is really what's happening (yes, I've the 3641AH with red leds but updated the for loop with code shared previously).

Hi !

Arduino/TM1638 links look good as the display is updated with cardashx text. Good. Are you running a race or a practice session ? We noticed that the current plugin works only in practice session. I'm currently working on a new plugin based on UDP data sent by the game (PC/PS4/XBoxOne)
Beside that, if when using the arduino console nothing is updated this means the problem is somewhere else. in the arduino code, uncomment the #define DEBUG line and upload the sketch. Then the console should be more interesting. Please note that running a game (PCars) with debug mode will fill the RX/TX buffer making the display behave strangely. DEBUG is to be used only with arduino console

hi
ihave the problem that the arduino make a problem by the sketch.
i have the files from the first post.
but when i will the sketch sent to the arduino than said he to me that:
CarDashX:446: error: 'struct EEPROMClass' has no member named 'readByte'
CarDashX:447: error: 'struct EEPROMClass' has no member named 'readByte'
CarDashX.ino: In function 'void loop()':
CarDashX:497: error: 'struct EEPROMClass' has no member named 'updateByte'
CarDashX:498: error: 'struct EEPROMClass' has no member named 'updateByte'
CarDashX:499: error: 'struct EEPROMClass' has no member named 'updateByte'

What iss the problem what i have????

I think this might help:
http://playground.arduino.cc/Code/EEPROMex
Of particular note, "The library can be downloaded through the Arduino or PlatformIO library manager".
There is a difference between the EEPROM library and EEPROMex library (which is a separate download).
