what’s going on?

thank’s in advance


I have compiled it’s demo(Blink) ,but it worked well.
Which board of tools did you choose?Could you provide some pictures for us to show it more clearly, so we can solve your problem more quickly.
Thanks a lot.

Hi, finally i figured out what was going on.

I have installed MinGW and to make it work i did some “manual configurations” basically some “environement variables” one of them tells the directory of gcc (wich i assume is used somewhere by the arduino software) as soon as i deleted those references, voila, Check started to work.

Then when trying to upload i had some “time outs”, i look in forums for same problems and i changed in the boards.txt the following:



and i had to change the Manual_reset/Auto switch to Auto to get it work.

from this point on all seems to work ok, i’m using the arduino mega with the tft libraries with out any problem.
