Ciao a tutti,
non ne vengo fuori e vi chiedo un aiuto.
Devo azionare dei rele e contemporaneamente acquisire degli analog input ed altri segnali via I2C.
Ho provato ad integrare un programma di acquisizione per un HST1x (temperatura ed umidità) con l'esempio del blinkwithoutdelay. Non funziona! In pratica il led lampeggia con il delay e non con la sua routine.
Qualcuno mi può dire dove sbaglio?
Grazie in anticipo a tutti.
Andrea.
#include <SHT1x.h>
#define dataPin 22 // DATA
#define clockPin 24 // SCK
SHT1x sht1x(dataPin, clockPin); // temp and humidity sensor
// constants won't change. Used here to
// set pin numbers:
const int ledPin = 2; // the number of the LED pin
// Variables will change:
int ledState = LOW; // ledState used to set the LED
long previousMillis = 0; // will store last time LED was updated
// the follow variables is a long because the time, measured in miliseconds,
// will quickly become a bigger number than can be stored in an int.
long interval = 1000; // interval at which to blink (milliseconds)
void setup() {
// set the digital pin as output:
pinMode(ledPin, OUTPUT);
Serial.begin(9600);
Serial.println("Starting up");
Serial.print("Temperature: ");
Serial.println("F. Humidity: ");
}
void loop()
{
// here is where you'd put code that needs to be running all the time.
// check to see if it's time to blink the LED; that is, if the
// difference between the current time and last time you blinked
// the LED is bigger than the interval at which you want to
// blink the LED.
unsigned long currentMillis = millis();
if(currentMillis - previousMillis > interval) {
// save the last time you blinked the LED
previousMillis = currentMillis;
// if the LED is off turn it on and vice-versa:
if (ledState == LOW)
ledState = HIGH;
else
ledState = LOW;
// set the LED with the ledState of the variable:
digitalWrite(ledPin, ledState);
}
{
float temp_c;
float humidity;
temp_c = sht1x.readTemperatureC();
humidity = sht1x.readHumidity();
{
}
Serial.print(temp_c);
Serial.print(" ");
Serial.print(",");
Serial.print(humidity);
Serial.print(" ");
Serial.println(",");
delay(5000);
}
