hey. Im compiling a coding that related to touch screen and arduino mega. I'm using ILI9481 touch screen LCD. Currently when I compile my coding, the 'drawFrame' error kept popping up and I don't know what is the problem there.
it says " 'drawFrame' was not declared in this scope ". Can somebody explain what could be error be?
Thanks in advanced.
This might help:
it says " 'drawFrame' was not declared in this scope ". Can somebody explain what could be error be?
As wild guess I would say that the problem is that drawFrame is possibly a function or a variable that is not declared in the relevant scope if indeed it is declared at all.
If you post your code and the full error message it would help, don't you think ?

these are my coding.i hope u guys that can take a look at them. do tell me the mistakes.
The program calls the drawFrame() function multiple times but the function is not in the code you posted.
It also does
drawBatteryCapacity;
which is meaningless. If it meant to call a function then it doesn't but even if it did the function does not exist in the program.
Where did you get the code ?
so what should i add to correct the problem?

Add the functions and call them properly.
I ask again. Where did you get the code ?
