Labview Serial Arduino
Hi there and thanks for the response.Im using an arduino mega.To obtain the value from pt 1000 i just use a voltage divider using a presicision resistor of 1000 kohm in series .I take the analogue value of the divider and feed it to arduino and from there im printing it to the serial port .in this way (valuept1,valuept2) (/n) . Its a simple code .Im planning to do the conversion from adc value to propper temperature value later afer i manage to stabilize the values.
// These constants won't change. They're used to give names
// to the pins used:
const int analogInPinLEFT = A0; // Analog input pin that the potentiometer is attached to
const int analogOutPinRIGHT =A1; // Analog output pin that the LED is attached to
// constants of the Pt 1000 formulas
int LEFT = 0; // value read from the left motor
int RIGHT = 0; // value read from the right motor
void setup() {
// initialize serial communications at 9600 bps:
Serial.begin(9600);
INTERNAL2V56 ;
}
void loop() {
// read the analog in value:
LEFT = analogRead(analogInPinLEFT);
RIGHT = analogRead(analogOutPinRIGHT);
// print the results to the serial monitor:
Serial.print(LEFT);
Serial.print(",");
Serial.print(RIGHT);
Serial.print("\n");
// wait milliseconds before the next loop
// for the analog-to-digital converter to settle
// after the last reading:
delay(200);
}
to answer your question im not using Lifa or Linx in that matter .Do i have to purchase them if i dont have them ?
So my real problem is that spike that you see and comes on both values at the 186th meassured value as im counting the commas just to make sure where exactly is it happening.Propably a buffer overflow but i cant be sure as im amatuer in labview and arduino.
