nagendra_17:
Hi everyone,
i start work at ER-TFTM070-5 MODULE WITH ARDUINO MEGA. when i compile my code every time some problem rises.....

error: 'class RA8875' has no member named 'fillScreen'
'class RA8875' has no member named 'changeMode'
'TEXT' was not declared in this scope

please give some solution.

Are you using the latest version of Arduino? I was having an issue with it on the older versions until I upgraded to the newer version.
