HY-TFT280 problem

[angelo56]

Hello,
I bought from you the 2.8 "TFT LCD with SD card from ebay. I tried in every way to make it work, getting only a white screen. I followed your wiki, I tried the old library (1.0) and the new UTFT 2.1, without success, only a white screen.
I also followed the advice of this forum, I tried to change all possible models but have no success. I checked all the jumpers to Arduino UNO and everything is ok.
However, I find it difficult to establish with certainty which model to use, ITBD02, ILI9325D_16, ILI9320_16.... because I can not figure out the exact model. The board you sent me has this text on silk screen: HY-280_262k heyaodz120820 and on the display: A478B-54-058-FP0902.
I do not know what to do. It could be a faulty board?
thanks for your assistance.
Angelo

Hi,friend
I am sorry for bring you problems .
Maybe it isn't introduced in great detail in WIKI, please select examples---Arduino (AVR)---UTFT_Demo_320x240 when you open the UTFT , you will see the
// Uncomment the next line for Arduino 2009/Uno
UTFT myGLCD(ITDB32S,19,18,17,16); // Remember to change the model parameter to suit your display module!

// Uncomment the next line for Arduino Mega
//UTFT myGLCD(ITDB32S,38,39,40,41); // Remember to change the model parameter to suit your display module!

plese select Uno or Mega .You don't need change nothing.

If any problem, do not hesitate to contact me.
Yours sincerely

Hi,
it is exactly what I did. I tried all the models, including those you suggested, and I have uncommented the line for Arduino Uno (UTFT myGLCD(ITDB32S,19,18,17,16);).
I have also tried just the sketch: UTFT_Demo_320x240 (Arduino AVR). The question is: which model should I set, according to the numbers which I have communicated?
However, I have little confidence to succeed, since I have already tried all models, as well as ITDB32S.
What else can I do?

thanks
Angelo

Hi ，friend
I am sorry for my carelessness.
When I read the WIKI of HY-TFT280 carefully,I note this word:
Note: The TFT controller model needs to be declared in the initializing statement. ITDB02 myGLCD(38,39,40,41) needs to be modified as myGLCD(38,39,40,41,ITDB32S) when using Arduino Mega2560.ITDB02 myGLCD(19,18,17,16,ITDB32S) needs to be commented when using Aduino UNO. Otherwise it just show a blank screen. In practice, RS, WR, CS, RSET can be connected to any free pin. But the pin number must be in accord with myGLCD(RS,WR,CS,RST).
You know the (RS,WR,CS,RST) connect to (A5,A4,A3,A2) not (19,18,17,16).

If any problem, do not hesitate to contact me.
Yours sincerely

Hello, it's very kind of you for quickly answering.
Your wiki refers to a modified version of the old and modified by you UTFT lib, which I have tried both either with myGLCD (19,18,17,16, TFT01_24) than with myGLCD (A5, 1A4, A3, A2, TFT01_24), and also other models, without success. However, the pin definition A5, A4, A3, A2 is the same as 19, 18, 17, 16 (on Arduino UNO).
Then I tried with the new library (UTFT 2.1 released March 29, 2013) with the models suggested by you and all the others by configuring the correct pins.
In my humble opinion, two things are possible. The display has a chip not managed from the library, or the board is broken.
Please check my first message, so you can tell me which model to use in the initialization line (also I send you my board photo).

thanks again
Angelo

Hi，friend
I am so sorry for the mistake in the WIKI and bring your problem.
I tested the HY-TFT280 and found a mistake in the WIKI,myGLCD(ITDB32S,19,18,17,16)needs to be modified as myGLCD(GEEE28,19,18,17,16) not myGLCD(19,18,17,16, TFT01_24).
This is our negligence,I apologize to you again.
Yours sincerely

Hi,
myGLCD (19,18,17,16, TFT01_24) is the configuration for the old library, I've tried. Instead myGLCD (GEEE28, 19,18,17,16) is for the new version (2.1 UTFT), I've also tried. I also tried GEEE24 and a lot of other models. I also checked all connections, check for continuity on all wires.
I think the board is broken ...

greetings

Hi,friend
I know your plight, and the UNO is instability to serve the HY-TFT280, Arduino Mega2560 is better .
Have you a Mega to test for the HY-TFT280 ?

If any problem, do not hesitate to contact me.
Yours sincerely

No, unfortunately I do not have access to a Arduino MEGA to test the HY-TFT280.
I send you a picture where you can see the pinout of TFT, which is different from that on the wiki, I do not know if it can be useful. Of course I followed the board's pinout.

Best regards

Hi,friend
I know what you mean ,you think it is "WR" in the WIKI ,but is "RW" on the board , they are same actually .
When I used the UNO to test the HY-TFT280,it was not sucessful until I try three different UNO board , however it always is sucessful when I used any MEGA.
So I think a good board is importent .
