Hi, I'm a complete beginner with programming, and as well as, using M5Stack Core 2 and TouchDesiger.
Does anyone know how to send accel data from M5Stack Core 2 to TouchDesigner via OSC?

Below is the code that I copied from several sources.
I could connect to the WiFi, but no response from TouchDesigner.
I am not sure what's missing..
Can someone teach me?

#include <M5Core2.h>
#include <WiFi.h>
#include <WiFiUdp.h>
#include <OSCBundle.h>

const char *ssid = "***";
const char *password = "***";

const char *udpAddress ="***";
const int udpPort = 10000;

WiFiUDP udp;

float accX = 0.0F;
float accY = 0.0F;
float accZ = 0.0F;

float gyroX = 0.0F;
float gyroY = 0.0F;
float gyroZ = 0.0F;

float pitch = 0.0F;
float roll = 0.0F;
float yaw = 0.0F;

float temp = 0.0F;

uint32_t Now = 0;
uint32_t lastUpdate = 0;
float deltat = 0.0f;


void setup(){
  M5.begin();
  M5.IMU.Init();
  delay(2000);
  Serial.println("*** setup *** aaa ***");
  delay(1000);

  WiFi.begin(ssid, password);
  while(WiFi.status() != WL_CONNECTED){
    delay(500);
    M5.Lcd.print(".");
  }

  M5.Lcd.println("WiFi Connected");
  M5.Lcd.print("IP address= ");
  M5.Lcd.println(WiFi.localIP());
}

void loop(){
  M5.update();
  if(WiFi.status() == WL_CONNECTED){

    OSCBundle bndl;


    udp.beginPacket(udpAddress, udpPort);
    bndl.send(udp);
    udp.endPacket();
    bndl.empty();
  }

  delay(10);

  M5.IMU.getAccelData(&accX,&accY, &accZ);
  M5.IMU.getTempData(&temp);
  deltat = ((Now - lastUpdate)/1000000.0f);
  lastUpdate = Now;

  MahonyAHRSupdateIMU(gyroX, gyroY, gyroZ, accX, accY, accZ, &pitch, &roll, &yaw);
  
}

Hi,

Can I ask a question?
I want to make an m5stack program that would play an mp3 file if I send a trigger via UDP, and would stop if I send a different trigger via UDP.
I followed some code from:
http://forum.m5stack.com/topic/143/lesson-6-1-speaker-mp3-player/9

But when I sent the trigger, the mp3 only played the first second (1s) and kept repeating the same time position. It wouldn't play the entire mp3 song.

This is the code that I used:

#include <M5Stack.h>
#include <WiFi.h>
#include <WiFiUdp.h>
#include "AudioFileSourceSD.h"
#include "AudioFileSourceID3.h"
#include "AudioGeneratorMP3.h"
#include "AudioOutputI2S.h"
#define N 1024

bool playing = true;
AudioGeneratorMP3 *mp3;
AudioFileSourceSD *file;
AudioOutputI2S *out;
AudioFileSourceID3 *id3;

const char* ssid = "wifiname";
const char* password = "wifipassword";
const int port = 5555;

// The udp library class
WiFiUDP udp;

void print_wifi_state(){
M5.Lcd.clear(BLACK); // clear LCD
M5.Lcd.setTextColor(YELLOW);
M5.Lcd.setCursor(3, 3);
M5.Lcd.println("");
M5.Lcd.println("WiFi connected.");
M5.Lcd.print("IP address: ");
M5.Lcd.println(WiFi.localIP());
M5.Lcd.print("Port: ");
M5.Lcd.println(port);
}

void setup_wifi(){
M5.Lcd.setTextColor(RED);
M5.Lcd.setTextSize(2);
M5.Lcd.setCursor(3, 10);
M5.Lcd.print("Connecting to ");
M5.Lcd.println(ssid);

// setup wifi
WiFi.mode(WIFI_STA); // WIFI_AP, WIFI_STA, WIFI_AP_STA or WIFI_OFF
WiFi.begin(ssid, password);
// WiFi.begin();

// Connecting ..
while (WiFi.status() != WL_CONNECTED) {
delay(100);
M5.Lcd.print(".");
}

// print state
print_wifi_state();

udp.begin(port);

}

void setup() {
M5.begin();
M5.Speaker.setVolume(5);
play('m');
// setup wifi
setup_wifi();

}

bool play(char dir){
switch(dir)
{
case 'm':
delete file;
delete out;
delete mp3;
mp3 = NULL;
file = NULL;
out = NULL;
file = new AudioFileSourceSD("/");
id3 = new AudioFileSourceID3(file);
out = new AudioOutputI2S(0, 1);
out->SetOutputModeMono(true);
mp3 = new AudioGeneratorMP3();
mp3->begin(id3, out);
playing = false;
return true;
default:
if(playing){
play('m');
return true;
}
break;
}
mp3->stop();
delete file;
delete out;
delete mp3;
mp3 = NULL;
file = NULL;
out = NULL;
file = new AudioFileSourceSD("/RainDrizzle.mp3");
id3 = new AudioFileSourceID3(file);
id3->seek(trackList->timePos, 1);
out = new AudioOutputI2S(0, 1);
out->SetOutputModeMono(true);
mp3 = new AudioGeneratorMP3();
mp3->begin(id3, out);
playing = true;

return true;
}

void loop() {
char packetBuffer[N];
int packetSize = udp.parsePacket();

// get packet
if (packetSize){

int len = udp.read(packetBuffer, packetSize);

if (len > 0){
  packetBuffer[len] = '\0'; // end
}

}

if(strcmp(packetBuffer,"start")==0){
// print param
M5.Lcd.clear(BLACK);
M5.Lcd.setCursor(3, 3);
M5.Lcd.setTextColor(GREEN);
M5.Lcd.println(packetBuffer);

play('t');

}

if(strcmp(packetBuffer,"stop")==0){
M5.Lcd.clear(BLACK);
M5.Lcd.setCursor(3, 3);
M5.Lcd.setTextColor(GREEN);
M5.Lcd.println(packetBuffer);
play('m');
}

if(playing){
  if(mp3->isRunning()){
    if(!mp3->loop()){
      mp3->stop();
      playing = false;
    }
  }
  else{
    delay(1000);
  }

}
M5.update();
}

Please advise if anything's wrong in the code.

Thank you in advance.

@lukasmaximus Yes.. I want to make an audio-haptic installation for a school project. :) And now I'm trying to make it wireless. By any chance, do you know how to send data from MAX/MSP to M5Stack (via udp, WiFi)?

Hi @lukasmaximus, I'm using the black core M5Stack.
I've tried what you suggested and now it's ok already. :)
Thank you so much for your help.

Hi,

I'm a newbie in M5Stack.
I would like to know if it's possible to turn off the M5Stack internal speaker and connect it to an external speaker (or vibrotransducer)?

I use the following vibrotransducer as my speaker: http://www.acouve.co.jp/product/pd_vp2.html
And PAM8403 amplifier.

Can anyone teach me how to connect all the parts with a schematic diagram (if possible)?

Thank you in advance.

Best regards!
