Olá....estou usando a biblioteca UTFT, tenho arduino mega, também testei no duemilanove, usando a pinagem igual da foto, mas fica como a foto abaixo, testei o UTFT myGLCD(CTE36,38,39,40,41); e UTFT myGLCD(ILI9327,38,39,40,41); em que estou errando? O tft é esse modelo: http://www.fpdisplay.com/search/sell-offer-270648.aspx

Um dos erros que estás a cometer é não mostrares o código que estás a usar...

O LCD está ligado a um shield?
This... is a hobby.

edsondragon

Estou conectando direto no mega nos pinos 22 ao 41

edsondragon

Estou usando essa pinagem

Isso parece-me imenso com ruído na ligacão... já tentaste prender um pouco mais os fios?
This... is a hobby.

Já tentei com vários exemplo de biblioteca, mesmo sendo pequeno a compilação e não da certo a tela fica igual a foto no inicio do post
