I am trying to read a string of text from text sent from an android phone to a bluesmirf silver mate.
I am using the code below to read a character from the serial and it puts it into a varaiable vl.
I want to send the text to the tft via testdrawtext ... however, if I put a string "info" in place of vl
it works fine but I am having problems sending a letter or number that is vl.
Is there a way to in arduino c to convert vl to a string?
============= code ============================
char vl ;
vl = bluetooth.read();
These are the errors I get:
error: invalid conversion from 'int' to 'char*'
error: initializing argument 1 of 'void testdrawtext(char*, uint16_t)'
