Hello PJRC peeps,
I am a newbie Teensyduino user that has run into an issue. I am attempting to make a glove with flex sensors on the fingers that can be assigned to any parameter in Ableton. Serial print in Arduino works fine. When I have the sensors assigned to a parameter in Ableton and playback is OFF it works. When I press the play back button it works for about a second then stops. i have tried switching to a shorter chord, making sure my computer is charging, and cross checked in max (it works in max)

Using Teensy LC and Adafruit flex sensors on a Mac


CODE:

/*
AnalogReadSerial

Reads an analog input on pin 0, prints the result to the Serial Monitor.
Graphical representation is available using Serial Plotter (Tools > Serial Plotter menu).
Attach the center pin of a potentiometer to pin A0, and the outside pins to +5V and ground.

This example code is in the public domain.

const int numReadings = 1000;

int readings[numReadings]; // the readings from the analog input
int readIndex = 0; // the index of the current reading
int total = 0; // the running total
int average = 0;

int inputPin = 15;

const int numReadings2 = 1000;

int readings2[numReadings2]; // the readings from the analog input
int readIndex2 = 0; // the index of the current reading
int total2 = 0; // the running total
int average2 = 0;

int inputPin2 = 17;


// the setup routine runs once when you press reset:
void setup() {
// initialize serial communication at 9600 bits per second:
Serial.begin(9600);
for (int thisReading = 0; thisReading < numReadings; thisReading++) {
readings[thisReading] = 0;
}
}

// the loop routine runs over and over again forever:
void loop() {
// read the input on analog pin 0:
int sensorValue = analogRead(15);
sensorValue = map ( sensorValue, 840, 940, 0, 127 );
sensorValue = constrain (sensorValue, 0, 127);

int sensorValue2 = analogRead(17);
sensorValue2 = map ( sensorValue2, 840, 940, 0, 127 );
sensorValue2 = constrain (sensorValue2, 0, 127);

// subtract the last reading:
total = total - readings[readIndex];
// read from the sensor:
readings[readIndex] = analogRead(inputPin);
// add the reading to the total:
total = total + readings[readIndex];
// advance to the next position in the array:
readIndex = readIndex + 1;



// if we're at the end of the array...
if (readIndex >= numReadings) {
// ...wrap around to the beginning:
readIndex = 0;
}

// calculate the average:
average = total / numReadings;
// print out the value you read:
Serial.println(sensorValue);
Serial.println(sensorValue2);
usbMIDI.sendControlChange ( 1, sensorValue, 1 );
usbMIDI.sendControlChange ( 2, sensorValue2, 1 );
delay(15); // delay in between reads for stability
}
