Nice price available to my location and look like they could be good to shrink some projects down! Anyone ever tried these eBay specials?

No but I wonder if the interface chip it uses ST7735R is compatible with the ST7735 (nothing immediately
springs out when comparing the datasheets).  The UTFT library supports ST7735 serial from what I can
glean.   Spend some time comparing the two datasheets perhaps?

Good idea I will take a look when I find some spare time

Riva

The ebay URL you supplied contains a download link to a file that appears to contain an Arduino library and example sketches for the device. The example sketches are .pde extension instead of .ino so the libraries may need modifying to work with Arduino IDE v1.0+

Ah right, I just found the link you mentioned. Is it easy to update the libs?

After downloading them to check what may need changing and I read they are Adafruit libraries so I suggest getting them direct from them to ensure latest versions. You need two libraries, this https://github.com/adafruit/Adafruit-GFX-Library and this https://github.com/adafruit/Adafruit-ST7735-Library I downloaded and compild them without problem but don't have a display to test them.

Hi Riva, that's good news! I think I will order a display then as it seems there should be a way to get them working :)

Can't go wrong for that price really!

Hi
I did :)
They are superb :D The PCB layout is easy to design and make. Now you can get this lcd on ready pcb adapter for few bucks.
I already ordered 3 of them. Adafruit library works wery well :)
i bought 2

so cheap as dirt :D

dtokez

Thats great stuff! So basically the cheaper one has no PCB but the slightly more expensive one is ready to be run from an arduino?

zachwiej

Yes :) I tested already one without pcb (I made my own) and its doing fine :)

This one looks interesting: 2.8" inch 320x240 Touch TFT LCD Display Module, SPI Interface, ILI9320 at USD14

I think that SPI can be for touch controler not the LCD

The pinout suggest that there is another variant of the board supporting SPI (LCDB rather than LCDA) - perhaps
same vendor has this one too?

I've got this one:

working nice with the latest adafruit's ST7735 library.
The only issue I see is it uses BGR565 color coding (the driver does expect RGB565 coded colors).. :~
