Hi all =)
during my latest looting of eBay i also bought an ILI9325 controlled 2.8" touch tft screen. I have successfully powered the backlight but other than that i haven't had any luck yet.
It appears i'm dealing with an Elecfreaks TFT01_28 (looks exactly like it, plus it boast the same controller) and according to their wiki (http://www.elecfreaks.com/wiki/index.php?title=2.8"_TFT_LCD:_TFT01-2.8) i'm supposed to use it with Henning Karlsen's UTFT. I downloaded that, hooked it up in various ways and still can't get it to work. The wiki tells me it's a 16bit lcd.
I'm using the following connections on my Arduino Pro Mini 16Mhz 5v running on 3.3v (runs fine with SPI screens, no issues there).
TFT => Arduino
DB0-7 => D8-15
DB8-15 => D0-7
RS => 19
WR => 18
CS => 17
RSET => 16 or Arduino Reset (no difference)
RD => supposed to be pulled high to 3.3v so it's connected to that directly
GND => GND
VCC => 3.3v / VCC pin on Arduino
LED A => 3.3v / VCC pin on Arduino
I have tried a myriad of different connections too. DB0-7 to ground with ILI9325D_8 as model in the UTFT init command. DB8-15 to D0-7, even tried Adafruit's TFTLCD and their connections:
DB0 => D8
DB1 => D9
DB2-7 => D2-7
CS => A3
CD / RS => A2
WR => A1
RD => A0
RSET => A4 or Arduino Reset (no difference)
VCC => 3.3v / VCC pin on Arduino
LED A => 3.3v / VCC pin on Arduino
I have used a default example of the UTFT library (UTFT => Arduino AVR => UTFT_Demo_320x240), only the initialiser has been altered (ILI9325D_8, ILI9325D_16, TFT01_28, ILI9325C) all with mixed an matched with the different connections too, for good measure.
I have also the example code that Adafruit's TFTLCD library comes with which is supposed to log the controller number back to the serial monitor, but all that gives me is the number 2525 ("Invalid controller chip: 2525" iirc).
I seriously have no other ideas. Some people have told me to grab a shield that plugs into an Uno R3 and then put this screen on that shield but i'm stubborn and i'm convinced that a simple 16bit parallel tft based on a ILI9325D should work just fine without a shield. Right?
