Ok, thanks for reply,

i am agree with you that both chips receiving the same info, but i am sure that CS1 and CS2 are not connected together and it works with the demo program !

Please, do you have other idea ?

Hello, thanks for this great forum !!!

 i'm running a 128x64 Graphic LCD with a Arduino MEGA 2560, and i try to make lines of text display on the screen,

Everything works fine with the demo Program, but with my program everything is displayed 2 times

this is a part of my program.

thanks

Code:

#include <glcd.h>
#include "fonts/Arial14.h"         // proportional font
#include "fonts/SystemFont5x7.h"   // system font

void setup()
{
  GLCD.Init();   // initialise the library, non inverted writes pixels onto a clear screen
}

void loop(){
  GLCD.ClearScreen();
  GLCD.SelectFont(System5x7);
  GLCD.Puts("PROGRAMME");
  GLCD.CursorTo (0 , 1);
  GLCD.Puts ("HEAT V1.06");
  delay (2000);
}

Hello,

i"m here to ask for a bad result of float data acquisition on NANO Card.

I'm acquiring, with PulseIn(), the lenght (in µS) of a square wave impulsion.

Next i want to transform it to Second.

The problem is that the Float variable is limited at 0,001, no more decimals available.

I also, tried with Double, and get the same problem.

--> Do you know how to increase the decimal numbers.


thanks

Olivier

Thank you Paul for your informations !

I found my mistake,
i changed the Date/Time values type to INT, removed ,DEC at the end of each string addition, everything is running bright !


Many thanks for your help


Regards

Ok PaulS, but how do you explain that there is value "10" for all Date/time values ?

I fell that my values are not formatted correctly, but how do you do it ?


Please let me know,

Regards

Hi, i can't find solution at my problem,

maybe someone coud help me !

I'm running with an arudino MEGA2560, DS1307 is connected via I2C, SD Card is connected to SPI.


On the first code, it is a function to acquire date on RTC DS1307 (date and time variables are declared as byte)

On the second part of code, it a a string arrangement to send values to SD CARD file.
For date and time values, the data sent to the file are always "10", i can't have the real date and time values, i'm sure that the DS1307 is giving good informations (it's working with demo program)

I feel that the problem is in string arrangement with date/time variable format.

Please can you help me ?


Thanks

Code:

void getDateDs1307()
{
  // Reset the register pointer
  Wire.beginTransmission(0x68);
  Wire.send(0);
  Wire.endTransmission();
  Wire.requestFrom(0x68, 7);
 
  second     = bcdToDec(Wire.receive() & 0x7F);
  minute     = bcdToDec(Wire.receive());
  hour       = bcdToDec(Wire.receive() & 0x3F);  // Need to change this if 12 hour am/pm
  dayOfWeek  = bcdToDec(Wire.receive());
  dayOfMonth = bcdToDec(Wire.receive());
  month      = bcdToDec(Wire.receive());
  year       = bcdToDec(Wire.receive());
 
  Serial.print(hour,DEC);
  Serial.print(":");
  Serial.print(minute,DEC);
  Serial.print(":");
  Serial.print(second,DEC);
  Serial.print(" ");
  Serial.print(dayOfMonth,DEC);
  Serial.print("/");
  Serial.print(month,DEC);
  Serial.print("/20");
  Serial.print(year, DEC);
  Serial.println();
}

Code:

getDateDs1307(); 

dataString = "*** ";                      // *** sur la chaine de caractères
        dataString += commentaire;                // Ajout de la chaine commentaire dans la chaine de caractères
        dataString += "***";                      // *** sur la chaine de caracteres
        dataString += ";";
        dataString += hour;
        dataString += ":";
        dataString += minute;
        dataString += ":";
        dataString += (second,DEC);
        dataString += ";";
        dataString += (dayOfMonth,DEC);
        dataString += "/";
        dataString += (month,DEC);
        dataString += "/20";
        dataString += (year,DEC);
       

Thank you PaulS, it works fine ! You tips was the right one !

Following, i found why my DS1307 was not working, i was missing Wire.begin() inside setup !

Now i still have a last problem before running my Arduino on heater:

On the first code, it is a function to acquire date on RTC DS1307 (date and time variables are declared as byte)

On the second part of code, it a a string arrangement to send it to SD CARD file.
The data sent to the file are always "10", i can't have the real date and time values, i'm sure that the DS1307 is giving good informations.

I feel that the problem is in string arrangement with date/time variable format.

Please can you help me ?

Hi PaulS, thanks for helping me,

my problem is with this part of code.

First, during serial connection, i write C with text after and sending to Arduino.
Arduino needs to read each character, adding the current date/time and write them inside SD file AND send the String to the serial.
The string sended to Arduino by Serial is for example: CAAA, but when arduino send it back to Serial, it sends 656565.

So i would him to send AAA.

Please help me,

Regards

Code:

if (command == 'C')                        // Si le caractère C est envoyé
          {
        int chrserial = 0;
        String dataString = "";
        String commentaire = "";
            for (int i=0 ; i<10 ; i++){
        chrserial = Serial.read ();             // Lecture du commentaire sur le port série
        commentaire += chrserial;
            }
           
        dataString = "*** ";                      // *** sur la chaine de caractères
        dataString += (commentaire);              // Ajout de la chaine commentaire dans la chaine de caractères
        dataString += "***";                      // *** sur la chaine de caracteres
        File dataFile = SD.open("data00.csv", FILE_WRITE);   // Ouverture du fichier Data00/csv sur la carte SD
            if (dataFile) {                                  // Si le fichier existe
            dataFile.println(dataString);                    // Ecriture de la chaine de caractères
            dataFile.close();                                // Fermeture du fichier dans la carte SD
            Serial.println ("Commentaire ajouté :");         // Envoi sur le porte série du résultat
            Serial.print (commentaire);                 // Envoi sur le porte série du commentaire ajouté
            }

Sorry,

i forgot to tell you, that i'm using Arduino Mega 2560, I2C connected to 20 et 21 (I2C SDA/SCL).
I'm sure it is a syntax problem, because when using DS1307 demo program, all is functionning ok !

For ASCII, i tried what you tell Serial.print(Val,DEC), but it continue giving a A as 65.

Please let me know

Olivier

Hi,
i'm neewby on arduino, so please i need help,
It is a datalogger with Analog senders, RTC DS1307 on SPI bus and SD Card
--> I can't make the Date/time functionning when building the String for SD File
--> I can't make the caracters sended to Serial being "A" and not 65, i feel that's is ASCII form, but i don't know how to convert it !

If someone have ideas, please, let me know !


Thanks

Hi, this code sounds good, value printed on screen is ok, but now, the code following the Serial comm. does not work properly (check for buttons), and the code joined is not working, variable rollTR is not shown on screen, do you know how to get printed, on screen, Gite "rollTR variable" ?

Thanks

Code:

MenuItem roll = MenuItem("Gite " , rollTR);

It works fine, now i can see the 5 numbers on 1 on Lcd, but how to extract the prefix and the value ?

Thanks

Oh, sorry, the int myStr[5] is now replaced by int myStr

Is that needed for read entire 5 numbers sent by Serial ?

hi, thanks for reply, i tried this code:
but the code received on lcd, is one number after one number, i really need to extract the prefix and the value,

wish you got idea, because i'm lost !

Thanks

Code:

  prefix = 0;
  if (Serial1.available() > 0) {      // get incoming byte:
      delay(5);
      //i=1;     
      //while(i<6){
         myStr = Serial1.read();
       //  i++;
      // Serial1.print(myStr[5]);
      lcd.setCursor(1,1);
      lcd.print(myStr , BYTE);   

Hi,
This is a RC Model Submarine, this section is for wireless diagnostic !

I need help on how to make my wireless communication working:

Wireless transmission by APC220 between 2 Arduino MEGA,

Operations:
I need, when the data arrive (2 numbers for prefix and 3 numbers for data), to be treated corresponding to the header value
for exemple: 01200
- No treatement at all !
- No variables printed beside menuItems, for example ( gite 200)
- The program is always on serial receive, and it is not possible to navigate through the menus.
- When navigation will be possible, i need a little temporisation between menu items when navigating
- Do the Serial Buffer is cleaned automatically ?

Many thanks for who can help me

Regards
