Hi,

I've just download megunolink and evrythings went fine till I try to upload a sketch (a basic checkbox) from my Arduino IDE to my Arduino wifi Rev2 board.
I get the message "error compiling"
I've been throw the forum and try serval things
* Install and reinstall the "megunolink" lirairy
* Install on an other computer the softwears
* modify parameters according the post "Arduino 1.6.0 Upgrade"

I can't get ride off that "error compiling"

Could you help me to solve that ?


Sketch:



#include "MegunoLink.h"


void SendToValueON()
{
InterfacePanel MyPanel;


// Retrieve value
MyPanel.GetValue(F("ValueON"), F("Value"));
MyPanel.GetValue(F("ValueON"), F("Minimum"));
MyPanel.GetValue("ValueON", "Maximum");

}






Arduino IDE end of error message

Hi,

There is a known problem with flash strings, which is causing your compile errors, in version 1.8.5 of the megaAVR toolchain
https://github.com/arduino/ArduinoCore- ... /issues/62

I was able to compile successfully with version 1.8.4, so that could be a work-around until we can find a more permanent solution.

Please let us know how you get on,
Paul.

Hi again,

I've modified our library to compile for the megaAVR platform. I don't have any hardware to test with currently though, and it is hard to get stuff shipped in the middle of this covid thing.

Would you mind testing for us please? The update is in our git repository here: https://github.com/Megunolink/MLP

If it doesn't work, you'll probably get weird serial messages with ? characters in them.

Have a good, virus free, day,
Paul.
