im kind of a newbie on arduino and i need help from experts :p
I've been able to display pretty much what i want on my GLCD TF7565 using th u8glib library. I'm able to display a string using this commande
u8g.drawStr(0, 0, "hello world");
but i want to display a double that i converted to a string but when i do something like this:
//code puting a double value in testString
u8g.drawStr(0, 0, testString);
the program is giving me an error while compiling, it says:
no matching function for call to 'U8GLIB_LM6059::drawStr(int,int,String&)
im i doing something wrong or its just impossible to display a previously stored String using the u8glib library ?
Thank you !
