Arduino Mega 2560 + ITDB02-2.8 +Itead shield V2.1

PIRA · September 10, 2016, 10:02am

Hello

I'm traing to get start with displays, for this, I have a ITDB02-2.8 ( IM120419011) display with the corresponding shield (IM120417024), both connected to an arduino mega 2560. In the display I can only see all the pixels turned on in white. The shield switch is in the 5v position. I changed the model parameter in example code like this:

UTFT myGLCD(ITDB28,38,39,40,41); //ITDB28 ILLI9325DS controller

I have cheked the pinout of RS,WR,CS,RST signals and there are connected like the definition.

Please, could you help me to fix this issue?

Thanks!!
