[SOLVED] Code suddenly gives error "Error compiling of board Arduino Mega..."

Using Arduino Programming Questions
1

Hi,

I am working on an IOT project with Blynk.
I am using a WW5500 Ethernet module, it works fine with the Blynk test for enthernet2(it connects to the server).
Yesterday my code compiled fine, but suddenly it gives this error.

Yesterday my code compiled fine, but suddenly it gives an errorArduino:1.8.13 (Windows Store 1.8.42.0) (Windows 10), Board:"Arduino Mega or Mega 2560, ATmega2560 (Mega 2560)"

It looks like it has to do with the library, but i didn’t mess with it.
I recompiled it many times (some other topics suggested that it might work).
I deleted and reinstalled both Eternet2 and Blynk libraries.
I also reinstaled the arduino boards...
But all without success.

If anyone knows how to solve this issue, i would really appreciate it!

update: in attachment you can find a verbose output.

In the Ethernet2 library is the line:

static const uint8_t CLOSED      = 0x00;

But in the Keypad library, CLOSED is defined as HIGH

 #define CLOSED HIGH

And in the Arduino core, HIGH is defined as 0x1

 #define HIGH 0x1

The end result is that the line in the Ethernet2 library looks like:

static const uint8_t 0x1  = 0x00;

That does not make syntactic sense.

It might work if you #include Ethernet2 (your // BLYNK section) BEFORE Keypad.

johnwasser:
It might work if you #include Ethernet2 (your // BLYNK section) BEFORE Keypad.

Your solution worked, after I put the "//BLYNK" section on top the sketch compiled just fine!

Thank you so much!

cheered too early...

it worked fine, but after 2 uploads (this project is still a work in progress) it stoped working again.

         add(last);

Is 'last' a function that you meant to call? That would be "last()".

6

sorry, I don't really get what you mean...
I don't think I'm using a function called last() or add(last) in my sketch.
It might be in one of the libraries tho.

Isaak

7

The virtualWrite() function doesn't have an overload that takes a function pointer.

Blynk.virtualWrite(V12, BH1750_return);

Perhaps you meant to write:

Blynk.virtualWrite(V12, BH1750_return());
8

Thx gfvalvo, it compiled!
I don't understand how I did not see that...

gfvalvo:
The virtualWrite() function doesn't have an overload that takes a function pointer.

That is probebly the reason that the error showed that there whas something wrong with the parameter.
