Maximum text length limitation #2

Closed AussieMakerGeek closed 2 years ago

AussieMakerGeek commented 2 years ago

Hi, first off, thanks for taking the time to author such a great library! With it I have been almost able to do everything i want BUT

There seems to be a limitation on the amount of characters we can use with item.text() function as well as item.attribute("txt", )

I am trying to write a long (113 char) url to the text attribute of a QRCode object but it would seem there is a limitation of about 30-40 characters. Smaller strings work fine.

I worked it out:

Changing the defines :

#define ATTRIBUTE_TEXT_LENGTH   150
#define ATTRIBUTE_TEXT_LENGTH_X 150

Allowed me to process the longer strings!

Thanks Again.
