ILI9325 TFTLCD

[EX-RIDER]

I am completely new to all of this but I am having a blast. I am using the UNO along with the TFTLCD files provided by Adafruit and company and it is working really well. My question is in regards to the Data pins. Am I stuck with using pins 2-9 or can I shift them to 3-10? I am using a hall effect sensor and I really need pin 2 for its interrupt capability or I think I do anyways. Any suggestions?

You should be able to re-map these to different pins.

Your right and thank you for responding...thats what I was hoping to do but I unfortunately don't understand the TFTLCD.h file completely. Any suggestions? Hopefully a point in the right direction can get me going. Thank you!

The pin definitions are in the TFTLCD.CPP file. Note that the pins are defined in terms of the native ATMEGA ports, not the more familiar Arduino pin numbers.

AHHH... That makes more sense. Thank you for your help. I think I got it now.

look for this

Code: Select all

// for the breakout board tutorial, two ports are used :/
#define DATAPORT1 PORTD
#define DATAPIN1 PIND
#define DATADDR1 DDRD

#define DATAPORT2 PORTB
#define DATAPIN2 PINB
#define DATADDR2 DDRB

#define DATA1_MASK 0xFC // top 6 bits
#define DATA2_MASK 0x03 // bottom 2 bits


you will want to change the MASK
remember that both MASKs together MUST cover all the pins from 0-7 so basically "DATA1_MASK | DATA2_MASK" must be 0xFF
