Dear David. I'm having difficulty connecting a 4.3 'TFT on an SSD1963 controller to an Arduino DUE. I have:

prenticedavid commented 5 years ago

I use the CTE Adapter shield. I modify it to enable it to use the RD pin. If you do not connect the RD pin, the ID will appear as 0xD3D3 and you have to force tft.begin(0x1963);

If you wire all the specified pins from your 40-pin display exactly like CTE, it should work fine. It defaults to 5 inch 800x480

David.

kluv58 commented 5 years ago

In the UTFT library everything loads well. TFT is defined as ITDB43 I load the code:

include

MCUFRIEND_kbv tft;

define BLACK 0x0000

define BLUE 0x001F

define RED 0xF800

define GREEN 0x07E0

define CYAN 0x07FF

define MAGENTA 0xF81F

define YELLOW 0xFFE0

define WHITE 0xFFFF

define ACTIVE RED

define PASSIVE GREEN

uint16_t g_identifier;

void setup() { tft.begin(0x1963); tft.setRotation(3); }

void loop() { tft.fillScreen(RED); tft.setCursor(50, 100); tft.setTextColor(WHITE, RED); tft.setTextSize(10); tft.print("SSD1963"); delay(1000); tft.fillScreen(GREEN); tft.setCursor(50, 100); tft.setTextColor(WHITE, GREEN); tft.setTextSize(10); tft.print("SSD1963"); delay(1000); tft.fillScreen(BLUE ); tft.setCursor(50, 100); tft.setTextColor(WHITE, BLUE); tft.setTextSize(10); tft.print("SSD1963"); delay(1000); tft.fillScreen(MAGENTA); tft.setCursor(50, 100); tft.setTextColor(WHITE, MAGENTA); tft.setTextSize(10); tft.print("SSD1963"); delay(1000); } The screen remains white.

prenticedavid commented 5 years ago

If it works with UTFT, please quote which constructor you have used. And how you have configured hardware/arm/HW_ARM_defines.h

David.

kluv58 commented 5 years ago

Do you mean these lines? // CTE TFT LCD/SD Shield for Arduino Due // ------------------------------------- // Uncomment the following line if you are using this shield //#define CTE_DUE_SHIELD 1 // // For this shield: RS=25, WR=26, CS=27, RST=28 //****

// ElecHouse TFT LCD/SD Shield for Arduino Due // ------------------------------------- // Uncomment the following line if you are using this shield //#define EHOUSE_DUE_SHIELD 1 // // For this shield: RS=22, WR=23, CS=31, RST=33 //****

so I did not edit them. there it started right away with a standard example: UTFT_Demo_480x272 with appropriate wiring.

kluv58 commented 5 years ago

UTFT wiring: UTFT myGLCD(ITDB43,38,39,40,41); DB0...DB7 - D37...D30, DB8...DB15 - D22...DD29

prenticedavid commented 5 years ago

In which case I assume that you are using a regular Mega Adapter shield instead of the CTE Due Adapter.

USE_SPECIAL USE_MEGA_16BIT_SHIELD

Please post a link to the Adapter you are using. Do not use the link icon. It is easier to paste the link.

David.

kluv58 commented 5 years ago

there is no adapter as such, everything is connected via a loop IMG_20190412_142950

prenticedavid commented 5 years ago

You have clearly used the regular Mega Adapter wiring if UTFT works.

kluv58 commented 5 years ago

Yes, but I want to use your library with this display. what with any wiring that you advise

Perhaps I did not understand your answer. with the UTFT library I use normal wiring Mega Adapter, and with your library I use the wiring specified in my post number 1

prenticedavid commented 5 years ago

I told you to use: USE_MEGA_16BIT_SHIELD

When you say "it works with UTFT" I expect you to use the same wiring for MCUFRIEND_kbv.

kluv58 commented 5 years ago

I will try, but I have doubts

kluv58 commented 5 years ago

result with your library "MCUFRIEND_kbv.h": IMG_20190412_170624

prenticedavid commented 5 years ago

USE_SPECIAL USE_MEGA_16BIT_SHIELD

tft.begin(0x1963);

From mcufriend_special.h:

#elif defined(__SAM3X8E__) && defined(USE_MEGA_16BIT_SHIELD)  //regular MEGA shield on DUE
#warning USE_MEGA_16BIT_SHIELD
#define USES_16BIT_BUS

LCD_RD pin should be connected to D43. If it is connected, you can read the ID. UTFT has no concept of reading the TFT. It ignores the RD pin.

Note that you should get an orange message saying: USE_MEGA_16BIT_SHIELD if you have configured the USE_SPECIAL correctly.

kluv58 commented 5 years ago

Yes, everything is set:

prenticedavid commented 5 years ago

Please don't post reams of messages. I just wanted you to check the USE_SPECIAL messages. e.g.

#warning USE_MEGA_16BIT_SHIELD
#warning WE ARE USING A SPECIAL CUSTOM DRIVER

That looks fine.

Have you connected LCD_RD pin? Have you forced tft.begin(0x1963) ? Are you using the current Beta ? Or any particular date?

I can test a regular write-only 16BIT_SHIELD on a Due. I can test a CTE_Adapter on a Due with 800x480 SSD1963

I don't feel like wasting my time if you don't answer my questions

David.

kluv58 commented 5 years ago

RD is connected to D43 tft.begin (0x1963) is installed in the code Last version installed = 2.9.9-Beta

kluv58 commented 5 years ago

This adapter fits my display? https://www.elechouse.com/elechouse/index.php?main_page=product_info&cPath=148_211&products_id=2251&zenid=2ushkiisg0sjfu6d9jsfiopqb4

prenticedavid commented 5 years ago

Yes, the Elechouse Adapter should work. I think that I have USE_ELECHOUSE_DUE_16BIT_SHIELD in mcufriend_special.h

But the existing USE_MEGA_16BIT_SHIELD should work.

If you have RD is connected to D43 what does tft.readID() say?

David.

kluv58 commented 5 years ago

port monitor responds: ID = 0x1963 if you don't have to do USE_ELECHOUSE_DUE_16BIT_SHIELD but, I think it will help a little. after all, in essence, this is a reassignment of pins, which can be done with loops

kluv58 commented 5 years ago

everything earned !!! It was necessary to remove a comment from define SUPPORT_1963 in MCUFRIEND_kbv.cpp but there are still questions on image size and color, but it's for tomorrow

prenticedavid commented 5 years ago

Ah-ha. I had just gone to the effort of plugging a RM68140 Mega shield into the Due. I defined USE_SPECIAL and USE_MEGA_16BIT_SHIELD. I forced tft.begin(0x6814).

It all works fine.

SUPPORT_1963 is enabled by default. From MCUFRIEND_kbv.cpp:

#define SUPPORT_1963 //only works with 16BIT bus anyway

You will see that there are several initialisation sequences. If you select


        table8_ads = SSD1963_480_regValues, table_size = sizeof(SSD1963_480_regValues);
        p16 = (int16_t *) & HEIGHT;
        *p16 = 272;
        p16 = (int16_t *) & WIDTH;
        *p16 = 480;

It should support your display. Please let me know if there is a problem with colours, dimensions, scroll directions. Note that Rotation=0 is 480x272. I know it looks like Landscape but this means vertical scroll.

David.

kluv58 commented 5 years ago

Thanks for the comment. It's already night. I'll try to do everything tomorrow. I will definitely write about the results.

Dear David. After adjusting the lines you specified, everything fell into place. IMG_20190413_073124 Now I will try on the screen 7 ' Thanks for participating and your advice.

prenticedavid commented 5 years ago

Please look back over this thread. What was your problem?

Verify wiring by testing with UTFT
Then test with LCD_ID_readreg. Edit the pin defines to match your wiring.
Then edit USE_SPECIAL, USE_MEGA_16BIT_SHIELD
Look for orange warning messages when building library.
Run examples. Copy-Paste the Serial Terminal messages.
I strongly advise buying a Due Adapter shield. The CTE/Sainsmart adapter is cheap.
The Elechouse adapter looks convenient for accessing other GPIO pins on the Due..

David.

kluv58 commented 5 years ago

ok i'll follow your advice. once again THANKS for participation!

kluv58 commented 5 years ago

Good evening, David! I got an adapter for my screens. Everything worked the first time, but another problem arose: on the screen 7 'the image is printed mirror, that is, from the right - to the left. On the screen 4.3' everything is fine. Tell me what and where to fix?

jsweet13 commented 5 years ago

When that happened to my screen, I decided to paint pixels backwards after creating a 64-bit character font to fix my issue.

I started with X = 319 (the 320th position) and subtracted 1 from X per pixel while keeping the Y coordination the same.

Doing that painted pixels from left to right, top to bottom. Hope that helps, it took me about 4 hours to calibrate my code around writing to the screen backwards so it looked regular.

You have a 480x272 SSD1963 screen as shown in your photo from 13 April 2019. Look for this sequence in MCUFRIEND_kbv.cpp :

#if defined(SUPPORT_1963) && USING_16BIT_BUS 
    case 0x1963:
        _lcd_capable = AUTO_READINC | MIPI_DCS_REV1 | READ_NODUMMY | INVERT_SS | INVERT_RGB;

And remove the INVERT_SS attribute.

There are other ways of doing it. Which "regValue" array are you using ? I suspect that your 7 inch screen is 800x480

David.

kluv58 commented 5 years ago

Yes, my screen 7 'has a resolution of 800x480. I am using an array: table8_ads = SSD1963_NHD_70_regValues, table_size = sizeof (SSD1963_NHD_70_regValues);

p16 = (int16_t ) & HEIGHT; p16 = 480; p16 = (int16_t ) & WIDTH; p16 = 800; When deleted:

| INVERT_SS

everything fell into place, i.e. The picture is displayed from left to right. Then another question arises: When moving from one display to another, will you need to edit the library every time?

prenticedavid commented 5 years ago

Yes, you would need to edit. Or you could invent an "imaginary" 0x1964 ID. Put your 480x272 into a different case 0x1964: block.

Obviously you would need to force tft.begin(0x1964); instead of relying on tft.readID()

David.

kluv58 commented 5 years ago

Well, tomorrow I will write down all the necessary changes in a notebook for memory and close the question. Thanks again for the help !!!
