Error ‘POSITIVE’ was not declared in this scope

Recommended Posts

Incerc sa incarc schita de aici - https://pa3csg.nl/?page_id=68 -  in Arduino Nano, dar imi apare eroarea ‘POSITIVE’ was not declared in this scope. Am folosit o multime de biblioteci (inclusiv cate o singura biblioteca in folderul Arduino sa nu apara conflicte), dar in zadar.

Exemplele "hello world" functioneaza fara nicio problema, mai putin acesta (https://forum.hwkitchen.cz/viewtopic.php?t=2439)

 

#include <Wire.h>

#include <LiquidCrystal_I2C.h>

 

LiquidCrystal_I2C lcd(0x27, 2, 1, 0, 4, 5, 6, 7, 3, POSITIVE);

 

void setup() {

  lcd.begin(16, 2);

  lcd.print("hello world");

}

 

void loop() {

 

}

 

Sunt depasit de situatie si sunteti ultima mea speranta.

Poti pune un printscrren direct din Arduino sa apara textul color acolo unde e cazul?

 

Ai incarcat libraria utilizata in Arduino?, nu e de ajuns sa o copezi undeva.....

Sketch -> Include Library -> Add zip library -> si apoi selectezi unde ai libraria salvata in format .zip

De ce nu pastrezi adresarea pinilor pentru I2C din skecthul care iti functioneaza?

De exemplu acesta:

 

#include <Wire.h>

#include <LiquidCrystal_I2C.h>

 

LiquidCrystal_I2C lcd(0x27, 16, 2);

void setup()

{

lcd.begin();

lcd.backlight();

lcd.print("hello world");

}

void loop()

{

}

Salut, eroarea pe care o primesti este din cauza folosirii gresite a librariei LiquidCrystal_I2C.h. Mai precis:

LiquidCrystal_I2C lcd(0x27, 2, 1, 0, 4, 5, 6, 7, 3, POSITIVE); --> asta nu exista in libraria LiquidCrystal_I2C si nici in libraria LiquidCrystal 

Daca folosesti un afisor LCD tip16x2 si are adaptorul I2C cu PCF8574(A) corect ar fi fost:

LiquidCrystal_I2C lcd(0x27, 16,2);

Daca in schimb folosesti acelasi tip de afisor dar fara adaptorul I2C, corect ar fi sa folosesti asta:

#include <LiquidCrystal.h>

LiquidCrystal lcd(12/*RS*/, 11/*EN*/, 5/*D4*/, 4/*D5*/, 3/*D6*/, 2/*D7*/);//pinul RW este conectat la masa (GND)

Incearca sketch-ul modificat de mai jos si spune daca iti functioneaza:

!!! Warning this version was tested only with TS-590 in standalone mode !!!
Please let me know, if works also with other radios....
Tested with:  TS-590
Should work with: TS-480, TS-990 and TS-2000

Change log:
I, PA3CSG, modified the unit for standard available relay boards from China / Ebay. I also added an I2C LCD display on
A4 and A5, saving a lot of wiring for the leds.
v 1.1.4 9.1.2014
               - chages by EA3NR TNX
               If the radio is powered off and the band decoder remains powered on, the band
               decoder output remains indefinitely showing the last selected band and never goes out of this status... It happens also if you
               power the radio off and then you power the radio on immediately.
v 1.1.3 17.2.2014
              - added 29 MHz and 51 and 52 MHz as 10m and 6m output TNX to Adam OK2IPW             
v 1.1.2 19.1.2014
              - solved bug in BCD output TNX to Frank - IZ4YDF 
v 1.1.1 10.12.2O13
              - minor change in serial comunication, now is source tested also with TS-590
v 1.1 13.9.2013
              - added BCD output like in YAESU RADIO to connect another accessories
                WARNING - only standard bands like 80,40,20,15,10 are suported on other bands are all BCD pins in low state

Nu este asta libraria corecta.

O gasesti in atasament.

Afisorul se conecteaza pe pinii A4 (SDA) si A5(SCL) pentru comunicatie I2C. 

Dupa ce o instalezi ar trebui sa folosesti sketch-ul I2CSniffer si sa identifici ce adresa are adaptorul.

void setup()
{
  Wire.begin();

  Serial.begin(9600);
  while (!Serial);             // Leonardo: wait for serial monitor
  Serial.println("\nI2C Scanner");
}


void loop()
{
  byte error, address;
  int nDevices;

  Serial.println("Scanning...");

  nDevices = 0;
  for(address = 1; address < 127; address++ ) 
  {
    // The i2c_scanner uses the return value of
    // the Write.endTransmisstion to see if
    // a device did acknowledge to the address.
    Wire.beginTransmission(address);
    error = Wire.endTransmission();

    if (error == 0)
    {
      Serial.print("I2C device found at address 0x");
      if (address<16) 
        Serial.print("0");
      Serial.print(address,HEX);
      Serial.println("  !");

      nDevices++;
    }
    else if (error==4) 
    {
      Serial.print("Unknown error at address 0x");
      if (address<16) 
        Serial.print("0");
      Serial.println(address,HEX);
    }    
  }
  if (nDevices == 0)
    Serial.println("No I2C devices found\n");
  else
    Serial.println("done\n");

  delay(5000);           // wait 5 seconds for next scan
}
 Apoi scrii adresa gasita de scanner in loc de 0x27 in :
LiquidCrystal_I2C lcd(0x27, 16,2); 

LiquidCrystal_I2C.zip

Sa recapitulam!

Schita cu "Hello world" functioneaza, in sensul in care pe afisor apare textul cu pricina? Daca da, atunci conexiunile sunt corecte, afisorul functioneaza si problema este in sketch-ul pe care l-am postat (si pe care banuiesc ca vrei sa-l folosesti si tu). Am inteles bine?

Incearca cu sketch-ul de mai jos si spune daca functioneaza:

 

#include <Wire.h>
#include "LiquidCrystal_I2C.h"

LiquidCrystal_I2C lcd(0x27, 16,2); 

void setup() {
  // put your setup code here, to run once:
  lcd.init();                      // initialize the lcd 
  lcd.init();
   lcd.backlight();
  lcd.setCursor(4,0); //Start at character 4 on line 0
  lcd.print("Welcome!");
  lcd.setCursor(5,1);
  lcd.print("PA3CSG");

 
}

void loop() {
  // put your main code here, to run repeatedly:

}

 Si ar trebui sa obtii asta:

Se pare ca functioneaza. Am inlocuit la schita postata de nico_2010, intuitiv, la plezneala de fapt, o linie de cod cu alte linii luate din Hello world. De fapt zvonacfirst mi-a sugerat ideea, dar nu m-am prins ce vrea sa zica. Nu inteleg mare lucru din chestiile astea dar am nevoie pentru anumite proiecte.

Multumesc tuturor care s-au straduit sa ma ajute.
