Eeprom__rd_buffer_size buffer_length

Hello Everyone,
I’m trying to load a sketch that works fine on a nano, that writes an EEprom memory.
But I get this error:

exit status 1
Errore durante la compilazione per la scheda Seeeduino XIAO.

Can anyone help me?

2

The error message is clearer and indicates that the BUFFER_LENGTH variable is not defined.

3

DO I have to declare it on Library or on code?

4

That library assumes that BUFFER_LENGTH has been #defined in Wire.h, which works for avr boards like the nano.
However…
The software tools developers for the Seeed XIAO boards did not define such a thing.

Next-to-bottom line: There is no way to define BUFFER_LENGTH in your sketch in a way that these library functions can compile.

You could try putting something like the following in the library file Eeprom24C01_02.h

 #define BUFFER_LENGTH 32

But, personally, I wouldn’t do this.

I would use Arduino’s Library Manager to install a more flexible library such as Rob Tillart’s excellent I2C_EEPROM library.

Bottom line: I have used this library for large and small I2C devices with a number of different CPUs (XIAO and oodles of other devices).

But using a new library implies to completely change the code, or not?

6

Well, adding the string into the library worked, but now I’m getting this error:

Note that I did not actually recommend adding that definition to the existing library. I meant to imply that it might be worth a try, but I personally would not and did not test it.

Since I have no idea what your code is, I can’t know what might need to be changed.

I know that I can read and write small and large I2C EEPROM devices using the library I suggested. I have used this library for a number of different CPUs, including the Seeed XIAO, which is the subject of this sub-forum.

Regards,

Dave

Definitely gonna try!

When I am migrating a program to a new platform, I pretend it’s a brand-new project and I implement/debug a step at a time. Your program has two libraries: a switch debouncer and some EEPROM stuff. (By the way, how the heck would you test your several hundreds of lines of code? You do beaucoup writes to EEPROM but never verify what was written, let alone do anything with it?)

Anyhow: Here’s my test program that starts with seeing if the switch press sequences do what I want. I also attached the zipped project, since copying from a browser sometimes screws up UTF-8 stuff. I also show the output from a test run where I pressed a few times.

The next step is, maybe, to write a single byte to EEPROM address 0 (a different value to location 0 for each of your cases). Then read it back and print it.
Once you get that going, then you are ready for a larger test where you actually write all of your stuff and do something with it.

You can keep the main loop() clean and easy to debug if you make each case call an appropriate function instead of putting long sequences in the main loop. But that’s just the way I would do it. You can implement it any way you want.

// Note that you don't need all of that bytexxx = xxx.  Just
// use the address value in the call to eeprom.write() and eeprom.read().

#include <Wire.h>
#include <I2C_eeprom.h>
#include <ClickButton.h>


// The library header file I2C_eeprom.h has definitions for the number of bytes
// for EEPROMs 24C01 through 24C512.  Use the appropriate definition here
// 
#define DEVICE_SIZE     I2C_DEVICESIZE_24LC04
#define EEPROM_ADDRESS  0x50

I2C_eeprom eeprom(EEPROM_ADDRESS, DEVICE_SIZE);
// Note that devices from I2C_eeprom.h have single-byte eeprom.read() and
// eeprom.write() functions and a lot of other stuff.


// My breadboard uses pin D1 for the switch
const byte btnPinTS = 1; //7; // Your code used pin 7
ClickButton button12(btnPinTS, LOW, CLICKBTN_PULLUP);

// Use LED_BUILTIN rather than a specific "magic number" since
// different boards might use different pins
const byte ledPin = LED_BUILTIN; //13 su arduino nano originale

// I don't think you really need this except, maybe to confirm
// its initial state.
int buttonStateTS;

void setup()
{

  Serial.begin(9600);
  // Boards like the XIAO have "native" serial connection, and you
  // must wait until the startup stuff is finished before you
  // print the output.  It doesn't hurt to do this even for boards like
  // the Uno or nano, which have external USB-to-logic converters.
  // So I almost always put this here.
  while (!Serial) ;
  
  Serial.println("Test program compiled on " __DATE__ " at " __TIME__);
  
  buttonStateTS = digitalRead(btnPinTS);
  Serial.print("Initial button state = "); Serial.println(buttonStateTS);
  pinMode(ledPin, OUTPUT);
        
 
  // Set time parameters for the switch debouncer
  // Note that you do not have to do anything with pinMode for the switch input.
  // It was taken care of when you created the button12 object.
  button12.debounceTime   = 20;   // Debounce timer in ms
  button12.multiclickTime = 250;  // Time limit for multi clicks
  button12.longClickTime  = 1000; // time until "held-down clicks" register
}

// Do you really need this?
int LEDfunction2 = 0;

void loop()
{
  // This sets the "clicks" value to whatever happened since the
  // last Update().  The "clicks" value won't be updated until the
  // switch is released, and won't change until the button is pressed
  // and released again.  (Well, if you hold it pressed for a "long
  // time" it will be -1.)
  button12.Update();
  
  if (button12.clicks != 0){
    // While debugging, give a clue as to what the program is seeing 
    Serial.print("\nbutton12.clicks = "); Serial.println(button12.clicks);
    // Do whatever else you might need here.  (Maybe nothing)
  } 

 // Use the "clicks" value to determine the action
 
 if(button12.clicks == 1){
    Serial.println("Scrivo vergine");

    // Do all of the stuff for 1 click

  } // End of 1-click stuff
    

  if(button12.clicks == 2){
    Serial.println("Carico 5.7€");

    // Do all of the stuff for 2 clicks
    
  } // End of 2-click stuff

  if(button12.clicks == 3){
    Serial.println("Carico 13€");

    // Do all of the stuff for 3 clicks
    
  } // End of 3-click stuff
   
  if(button12.clicks == 4){
    Serial.println("Carico 77€");

    // Do all of the stuff for 4 clicks
    
  } // End of 4-click stuff

  // If 1 <= button12.clicks <= 4
  // Maybe do something here to verify EEPROM contents
  
} // End of loop()
