Hello All,
I am working on one LabVIEW project reading sensor data using NI VISA.
Through VISA i am able to read sensor data and control GPIO.
But I have different different code for each sensor and for relay.
i tried to combined all 3 code but facing issue.
First code
// Basic demo for reading Humidity and Temperature
#include <Wire.h>
#include <Adafruit_MS8607.h>
#include <Adafruit_Sensor.h>
Adafruit_MS8607 ms8607;
void setup(void) {
Serial.begin(115200);
while (!Serial) delay(10); // will pause Zero, Leonardo, etc until serial console opens
Serial.println("Adafruit MS8607 test!");
// Try to initialize!
if (!ms8607.begin()) {
Serial.println("Failed to find MS8607 chip");
while (1) { delay(10); }
}
Serial.println("MS8607 Found!");
ms8607.setHumidityResolution(MS8607_HUMIDITY_RESOLUTION_OSR_8b);
Serial.print("Humidity resolution set to ");
switch (ms8607.getHumidityResolution()){
case MS8607_HUMIDITY_RESOLUTION_OSR_12b: Serial.println("12-bit"); break;
case MS8607_HUMIDITY_RESOLUTION_OSR_11b: Serial.println("11-bit"); break;
case MS8607_HUMIDITY_RESOLUTION_OSR_10b: Serial.println("10-bit"); break;
case MS8607_HUMIDITY_RESOLUTION_OSR_8b: Serial.println("8-bit"); break;
}
// ms8607.setPressureResolution(MS8607_PRESSURE_RESOLUTION_OSR_4096);
Serial.print("Pressure and Temperature resolution set to ");
switch (ms8607.getPressureResolution()){
case MS8607_PRESSURE_RESOLUTION_OSR_256: Serial.println("256"); break;
case MS8607_PRESSURE_RESOLUTION_OSR_512: Serial.println("512"); break;
case MS8607_PRESSURE_RESOLUTION_OSR_1024: Serial.println("1024"); break;
case MS8607_PRESSURE_RESOLUTION_OSR_2048: Serial.println("2048"); break;
case MS8607_PRESSURE_RESOLUTION_OSR_4096: Serial.println("4096"); break;
case MS8607_PRESSURE_RESOLUTION_OSR_8192: Serial.println("8192"); break;
}
Serial.println("");
}
void loop() {
sensors_event_t temp, pressure, humidity;
ms8607.getEvent(&pressure, &temp, &humidity);
Serial.print("Temperature: ");Serial.print(temp.temperature); Serial.println(" degrees C");
Serial.print("Pressure: ");Serial.print(pressure.pressure); Serial.println(" hPa");
Serial.print("Humidity: ");Serial.print(humidity.relative_humidity); Serial.println(" %rH");
Serial.println("");
delay(500);
}
and second code
// Basic demo for accelerometer readings from Adafruit LIS331HH
#include <Wire.h>
//#include <SPI.h>
#include <Adafruit_LIS331HH.h>
#include <Adafruit_Sensor.h>
// Used for software SPI
//#define LIS331HH_SCK 13
//#define LIS331HH_MISO 12
//#define LIS331HH_MOSI 11
// Used for hardware & software SPI
//#define LIS331HH_CS 10
Adafruit_LIS331HH lis = Adafruit_LIS331HH();
void setup(void) {
Serial.begin(115200);
while (!Serial) delay(10); // will pause Zero, Leonardo, etc until serial console opens
Serial.println("LIS331HH test!");
//if (!lis.begin_SPI(LIS331HH_CS)) {
// if (!lis.begin_SPI(LIS331HH_CS, LIS331HH_SCK, LIS331HH_MISO, LIS331HH_MOSI)) {
if (! lis.begin_I2C()) { // change this to 0x19 for alternative i2c address
Serial.println("Couldnt start");
while (1) yield();
}
Serial.println("LIS331HH found!");
lis.setRange(LIS331HH_RANGE_6_G); // 6, 12, or 24 G
Serial.print("Range set to: ");
switch (lis.getRange()) {
case LIS331HH_RANGE_6_G: Serial.println("6 g"); break;
case LIS331HH_RANGE_12_G: Serial.println("12 g"); break;
case LIS331HH_RANGE_24_G: Serial.println("24 g"); break;
}
// lis.setDataRate(LIS331_DATARATE_50_HZ);
Serial.print("Data rate set to: ");
switch (lis.getDataRate()) {
case LIS331_DATARATE_POWERDOWN: Serial.println("Powered Down"); break;
case LIS331_DATARATE_50_HZ: Serial.println("50 Hz"); break;
case LIS331_DATARATE_100_HZ: Serial.println("100 Hz"); break;
case LIS331_DATARATE_400_HZ: Seria
l.println("400 Hz"); break;
case LIS331_DATARATE_1000_HZ: Serial.println("1000 Hz"); break;
case LIS331_DATARATE_LOWPOWER_0_5_HZ: Serial.println("0.5 Hz Low Power"); break;
case LIS331_DATARATE_LOWPOWER_1_HZ: Serial.println("1 Hz Low Power"); break;
case LIS331_DATARATE_LOWPOWER_2_HZ: Serial.println("2 Hz Low Power"); break;
case LIS331_DATARATE_LOWPOWER_5_HZ: Serial.println("5 Hz Low Power"); break;
case LIS331_DATARATE_LOWPOWER_10_HZ: Serial.println("10 Hz Low Power"); break;
}
}
void loop() {
/* Get a new sensor event, normalized */
sensors_event_t event;
lis.getEvent(&event);
/* Display the results (acceleration is measured in m/s^2) */
Serial.print("\t\tX: "); Serial.print(event.acceleration.x);
Serial.print(" \tY: "); Serial.print(event.acceleration.y);
Serial.print(" \tZ: "); Serial.print(event.acceleration.z);
Serial.println(" m/s^2 ");
Serial.println();
delay(1000);
}
And Third
int Relay = 11;
char labview = 0;
void setup()
{
Serial.begin(9600);
pinMode(Relay,OUTPUT);
}
void loop()
{
if (Serial.available()>0)
{
labview = Serial.read();
if (labview== '1')
{
digitalWrite(Relay,HIGH);
Serial.println("HIGH");
}
if (labview== '2')
{
digitalWrite(Relay,LOW);
Serial.println("LOW");
}
}
}
I want to merge all three code.
Both sensor continious acquire data, and I can control the relay simultinusly without effect on sensor data.
So I need two while loop, in one loop for sensor data acquiring and another loop for relay control.
After merged I will upload this code in Arduino Uno Wifi R2 board and acquire data and control relay using LabVIEW.
What have you tried? How did it fail? Post your best effort and folks will help. Most folks won't simply do work for you.
You can't have 2 loops in your code, but you can do multiple things within your loop. It looks like you are sampling your temp/humidity every 500 msec and your accelerometer every second. Look at the BlinkWithoutDelay example in the IDE (File->examples->02.digital-BlinkWithoutDelay) to learn how to track elapsed time without blocking other code. It will enable you to measure your data and monitor serial input for your relay.
/*
Blink without Delay
Turns on and off a light emitting diode (LED) connected to a digital pin,
without using the delay() function. This means that other code can run at the
same time without being interrupted by the LED code.
The circuit:
- Use the onboard LED.
- Note: Most Arduinos have an on-board LED you can control. On the UNO, MEGA
and ZERO it is attached to digital pin 13, on MKR1000 on pin 6. LED_BUILTIN
is set to the correct LED pin independent of which board is used.
If you want to know what pin the on-board LED is connected to on your
Arduino model, check the Technical Specs of your board at:
