I’m a little stumped here. So I found a TFT that was compatible with the UTFT library. This is the first TFT I’ve ever wired up so I was taking it slow. Anyway, first things first I started looking over the schematics for the 16-bit 4.3” screen. See the Diagram attachment.
Simple enough right, 16 Data bus lines and then the required init pins(RW,RD,CS, etc)? So I then started looking in the code for some sort of macro or defines that tell me what pins DB0-DB15 on the TFT are supposed to correspond to on my Arduino DUE. I didn’t find anything in the code in that respect so then I started looking over the API for UTFT. I Found the init definitions and such but still no reference to where these DB pins go. Yes, there’s a handful of tutorials online but I just can’t get a grasp on it. I then did a search on the site and found an Arduino DUE pinout thinking maybe there was something I was missing but still, nothing that strikes me as a lead.
I Found a tutorial for an 8-bit 5v screen with these instructions but again, why 22-29. Is it defined somewhere or just something specific to the platform.
• DB0 to DB7 > Mega D22 to D29 respectively
• RD > 3.3 V
• RSET > D41
• CS > D40
• RW > D39
• RS > D38
• backlight 5V > 5V
• backlight GND > GND
I’ve wired up an LCD display before but I specified the pins explicitly when I created an instance of that LCD.
Can someone steer me in the right direction? Sorry for the noob-ness and thank You
