Code for engine sounds almost done. Got through the tough spot!

It's amazing the clarity and crisp sounding effects you have achieved. Well done.

Thx CRainford. These are just practice files. I will clean them up for the final version. For those of you interested in the code, I used a boolean state (true/ false) but in this case with 1 and 0. As you enter the PWM case for certain throttle stick positions, you initialize the command once (this was the first problem to solve), and then when you leave that particular case, the bool for the initial case is reset by the next case. As well as resetting the bool to T or F, the wav tracks have to loop-play-fade-stop appropriately. So it looks something like this (not the best solution but it works for my needs):

Code: Select all

case 0:

bool maxrpm = 0

//in the loop
// so for case 0, track 12 is the max rpm sound wav (planned engine tracks to be 1-12)
// and accel 5 would be track 11 (or whatever, but in some ordered structure)
// etc.....

    case 0:
   
      Serial.print("MAX RPM");
      digitalWrite(WAV2, HIGH); // not necessary, just for testing stick location w LED
      if (maxrpm == 0) {
        tsunami.trackLoop(12, 1);
        tsunami.trackPlayPoly(12, 0, true);     
        maxrpm = 1; // allows only ONE loop play on the wav track  even if stick held in same position
      }
      break;

    case 1:
    
      Serial.print("ACCEL5");
      tsunami.trackStop(12);       
      if (maxrpm = = 1) {
        maxrpm = 0;  // this resets the bool to allow case 0 to trigger again
      }
      break;

Well, I got to a point where I can't go any further due to insufficient experience with coding. I really need bit counting to run the Tsunami at it's best and to decode the sbus input. Without byte code, using the sbus to PWM decode method has reached its limits in my program. The problem is that everything works just fine, but due to very short transitions from one PWM duration to the next, some parts of the serial commands to the Tsunami get lost. So I am currently teaming up with Open Panzer to create some cool tank sounds. You will need a Teensy 3.2, some type of sound board, and a way to read your Rx signals either through sBus or direct pin inputs, Teensy downloader program, Tsunami library, and arduino IDE. My code is pretty simple so any of you who want to mess around with it feel free. Tsunami files already set for Teensy serial out 1. You could easily adapt it to do other things with Tx Rx. My next electronic project should be pretty cool, a hand held lidar room scanner with display screen (if it ever gets off the drawing board). More to come on the Elefant build!

xrad wrote:Thx Soeren. Here is convoy light in blue. 5mm LED heat shrink tube to aluminum tube holding the fiber. Luckily, it fit into body without hitting the subwoofer. The LED is plenty bright. I polished the inside ends of the fishing line w/1500 grit, but it was old poor quality line and not very reflective internally. But, I think it's scale brightness (in other words, dim).

I added some pics of the other convoy lights I made for other tanks on this site.

Hi, where did you get the convoy light?

Sorry, been busy. Hope to get the final elefant sounds for OPTCB sound board squared away in a few weeks. Yes, I make most of my Elefant parts. I put it on thingiverse near bottom of list. You will have to size it a bit for your needs:
