Udisplay support for rgb displays #17414

gemu2015 · 2022-12-16T16:51:39Z

Description:

adds new touch driver gt911
adds support for rgb displays to universal display driver
=> sunton esp32-s3 rgb display 800x480
the cheapest high res esp board available, very good display panel but a little slow
https://www.makerfabs.com/sunton-esp32-s3-4-3-inch-ips-with-touch.html

{"NAME":"SUNTON","GPIO":[1,1,1,1,1,1,1,1,1,1,6720,704,736,672,1,1,1,1,1,640,608,1,0,0,0,0,0,1,1,1,1,1,1,1,1,1,1,1],"FLAG":0,"BASE":1}

remark:
this driver does heavy DMA. obviously there is a clash with RGB PSRAM DMA and
a special heap call:
uint32_t free_block_size = heap_caps_get_largest_free_block(MALLOC_CAP_INTERNAL | MALLOC_CAP_8BIT);
it generates a divide by zero error when the display is enabled

there seams to be no other anomaly, everything else works without any problems

i had to disable this call by define
#define RGB_DISPLAY
otherwise get info crashes with zero divide error.

Price is really nice. But shipping :-( Do you know a other source?

gemu2015 · 2022-12-16T17:51:32Z

Shipping was 15 euros and arrived in 8 days !

Jason2866 · 2022-12-16T18:17:34Z

Thx. Had to create an account. Well really nice, latest S3 on board and touch is already included too + card reader. @s-hadinger Perfect for LVGL.

gemu2015 · 2022-12-16T18:26:43Z

i forgot an info.
this board is 16M_qio_opi

Jason2866 · 2022-12-29T18:08:29Z

Really nice display ;-) The template should set the A3 GPIO too.

will upload a autoconfig file...

Rushmed · 2023-02-23T12:35:14Z

Hi,
sorry if thats not th correct place for question.
I got the ESP32-8048S043 display. I flashed it via:

I added this template
an did the autoconf with

.

I am able to connect the webinterface but dont get the display to show anything.

Does anybody have an idea what I am doing wrong?

Maybe it has something to do with the template and autoconfig as ESP32-8048S050 has ST7262 and ESP32-8048S043 has ILI9485.

Jason2866 · 2023-02-23T12:40:40Z

Different display controller, so it needs a different display.ini to init.

Rushmed · 2023-02-23T14:17:06Z

So I do have to compile it?

Jason2866 · 2023-02-23T14:56:45Z

You have to read ;-) Start here https://tasmota.github.io/docs/Displays/#universal-display-driver

Rushmed · 2023-02-23T17:07:17Z

Ok thanks.

Jason2866 · 2023-02-23T17:20:18Z

Or is it this one #17326

Rushmed · 2023-02-23T20:42:01Z

No, the display I have is:
ESP32-8048S043 Specifications-EN.pdf

It`s strange I cant find any information for ILI9485.

Jason2866 · 2023-02-23T21:20:25Z

Strange managed to download the demo package from here http://www.jczn1688.com/zlxz
There is no mention of a ILI9485 anywhere.

@gemu2015 Can you help?

gemu2015 · 2023-02-24T07:40:50Z

sorry i can't , as long as there is no proven to work source code i am not willing to dig into this.
@Rushmed
you will have to compile a demo package for your display and if it is working well provide a link to the working source code.

Rushmed · 2023-02-24T07:51:26Z

@gemu2015 So I have to compile the code @Jason2866 sent and upload it to the device?
Any recommendation for test procedure or is the test passed when "Hello World!" is shown?

gemu2015 · 2023-02-24T07:53:15Z

yes "hello world" is enough

Rushmed · 2023-02-24T11:53:37Z

Ok, got it.
I followed this instruction:
Getting started 4.3 Inch.pdf

Now I have display output. Every every second another "Hello World" wit different color and background color is added to the screen.

FYI as in the instruction I needed to copy
lv_conf.h.txt
(Changed ending to .txt to be able to upload)
maybe it contains some useful information.

gemu2015 · 2023-02-24T13:27:31Z

ok, this seems to be the sunton-s3
apply the template from above (from @Jason2866 ), copy the sunton descriptor (ST7262_rgb16_display.ini)
as display.ini into file system and restart.

Rushmed · 2023-02-24T15:43:35Z

Ok, thanks for help.
I flashed again.
Applied:
{"NAME":"SUNTON","GPIO":[1,1,1,1,1,1,1,1,1,1,6720,704,736,672,1,1,1,1,1,640,608,1,0,0,0,0,0,6210,1,1,1,1,1,1,1,1,1,1],"FLAG":0,"BASE":1}
and copied
autoexec.be.txt
and
display.ini.txt
to file system.

Restarted bu no display output.

gemu2015 · 2023-02-24T15:46:13Z

if you took the very first template you have to enable udisplay by setting GPIO 0 to Option A3

Rushmed · 2023-02-24T15:50:32Z

No, i took the second one.

gemu2015 · 2023-02-24T15:57:01Z

your display.ini is complete garbage. it should only be a few lines

Rushmed · 2023-02-24T15:58:45Z

I used ST7262_rgb16_display.ini fom here and renamed it.

gemu2015 · 2023-02-24T16:00:30Z

look at the file size, it should have only have 164 bytes

Rushmed · 2023-02-24T16:01:32Z

Thanks, ill` check.

Rushmed · 2023-02-24T16:17:46Z

Now the backlight blinks three times on startup and then stays on and lower brightness. Screen stays black.

gemu2015 · 2023-02-24T16:19:19Z

what is in the console during boot ?

gemu2015 · 2023-02-24T16:33:42Z

this caused a reset,
please delete auto exec.be maybe it is also garbage.
if that doesn't not help
probably it isn't exactly this display, despite the backlight matches.

maybe it is the ILI chip variant. to adapt this is much more work

why don't you buy a display known to be supported by tasmota like the one above.

it is only 25 Euros + 15 euros shipping

Rushmed · 2023-02-24T16:49:58Z

Before buying I checked blakkers page an found ESP32-8048S050. Which I wasnt able to fin a seller.
I thought the difference between ESP32-8048S050 and ESP32-8048S043 is just the screen size.

Thanks anyway.

Rushmed · 2023-02-25T09:46:01Z

Which display is supported ESP32-8048S050, ESP32-4827S043?

gemu2015 · 2023-02-25T09:54:21Z

the one at start of this post with controller ST7262 800x480 pixels
(should be ESP32-8048S050)
see link above makerfabs.

Rushmed · 2023-02-25T10:18:34Z

The link in the first post is for a 4.3" display. No mention of a 5" screen.

According the these secifications the only display with ST7262 is the 5" one.
ESP32-8048S043 Specifications-EN.pdf
ESP32-4827S043 Specifications-EN.pdf
ESP32-8048S050 Specifications-EN.pdf

gemu2015 · 2023-02-25T10:33:01Z

quite confusing.
anyway i ordered the above display and implemented the driver. it is definitely an ST7262 with capacitive touch and it is 4,3 inch

btw i can not recommend resistive touch at all.

gemu2015 · 2023-02-25T10:38:56Z

i see the display is out of stock now. it was remarkably cheep. the 5 inch is more expensive. i don't know if its hardware compatible though despite it has the same display controller chip. but having the same chip only GPIO numbers may have to be changed.

gemu2015 · 2023-02-25T10:58:15Z

what you can try is to identify your currents display gpio definitions.
they are in hello world.ino like below for 5 inch:

these pins must be transposed into display.ini.
since it is a RGB panel no specific chip opcodes apply.

in the tasmota display docs you will find further explanation how to
setup Display.ini. take the ini file for St7262 as a template and modify the GPIO to fit your device.

Arduino_ESP32RGBPanel bus = new Arduino_ESP32RGBPanel(
GFX_NOT_DEFINED / CS /, GFX_NOT_DEFINED / SCK /, GFX_NOT_DEFINED / SDA /,
40 / DE /, 41 / VSYNC /, 39 / HSYNC /, 42 / PCLK /,
45 / R0 /, 48 / R1 /, 47 / R2 /, 21 / R3 /, 14 / R4 /,
5 / G0 /, 6 / G1 /, 7 / G2 /, 15 / G3 /, 16 / G4 /, 4 / G5 /,
8 / B0 /, 3 / B1 /, 46 / B2 /, 9 / B3 /, 1 / B4 */
);
// option 1:
// ST7262 IPS LCD 800x480
Arduino_RPi_DPI_RGBPanel gfx = new Arduino_RPi_DPI_RGBPanel(
bus,
800 / width /, 0 / hsync_polarity /, 8 / hsync_front_porch /, 4 / hsync_pulse_width /, 8 / hsync_back_porch /,
480 / height /, 0 / vsync_polarity /, 8 / vsync_front_porch /, 4 / vsync_pulse_width /, 8 / vsync_back_porch /,
1 / pclk_active_neg /, 16000000 / prefer_speed /, true / auto_flush */);

Rushmed · 2023-02-25T20:08:17Z

quite confusing. anyway i ordered the above display and implemented the driver. it is definitely an ST7262 with capacitive touch and it is 4,3 inch

btw i can not recommend resistive touch at all.

Thats confusing me even more as there is no 800x480 Sunton display with ESP and resistive touch.

Tried editing the display.ini but for example the first line is:
:H,ST7262,800,480,16,RGB,40,41,39,42,2,15,16,4,45,48,47,21,14,8,3,46,9,1,5,6,7,12
Up to RGB I understand but why there are 22 numbers after RGB.
Following the instruction there have to be 9.

gemu2015 · 2023-02-26T07:33:23Z

look at point 6: b0-b5 are 6 GPIO pins named b0,b1,b2 etc.

Rushmed · 2023-02-27T10:22:55Z

I did the transformation with the "hello world" code.
:H,ST7262,800,480,16,RGB,40,41,39,42,BL,8,3,46,9,1,B5,5,6,7,15,16,4,45,48,47,21,14,PixelSpeed
I did not find values for backlight, B5 and pixel clock speed in MHz.

Curious that this does not fit to the wiring diagram in the documentation.

gemu2015 · 2023-02-27T11:59:33Z

sorry doku error b goes from b0-b4 , try pixel clock 12
you must also match
:V line with hsync_polarity etc.

Rushmed · 2023-02-27T16:33:07Z

Now my display.ini looks like this:
:H,ST7262,800,480,16,RGB,40,41,39,42,2,8,3,46,9,1,5,6,7,15,16,4,45,48,47,21,14,16 :S,2,1,1,0,40,20 :V,0,8,4,8,0,8,4,8,1 :0,00 :1,01 :2,02 :3,03 :TI1,5d,20,19,-1,38 #
Backlight blinks three times on startup and stays on, no more life sign.

Starting with this .ini I still get no display output but I am able to toggle backlight and displaydimmer comand is working.
:H,ILI9488,480,320,16,PAR,16,-1,37,36,35,48,45,47,21,14,13,12,11,10,9,3,8,16,15,7,6,5,4,20 :S,2,1,1,0,40,20 :I E0,0F,00,03,09,08,16,0A,3F,78,4C,09,0A,08,16,1A,0F E1,0F,00,16,19,03,0F,05,32,45,46,04,0E,0D,35,37,0F C0,2,17,15 C1,1,41 C5,3,00,12,80 36,1,48 3A,1,55 B0,1,80 B1,1,A0 B4,1,02 B6,2,02,02 E9,1,00 F7,4,A9,51,2C,82 11,80 29,0 :o,28 :O,29 :A,2A,2B,2C,16 :R,36 :0,28,00,00,85 :1,88,00,00,02 :2,E8,00,00,84 :3,48,00,00,00 :i,20,21 :TI1,38,*,* :B,20,0 #

gemu2015 · 2023-02-27T16:58:46Z

the formatting of display.ini is important too. the line endings MUST be Linefeed not carriage return. (i assume this to be wrong because the formatting of your post above ist strange)

it would help if you enable debugging in universal display driver and monitor the output of serial monitor during startup.
edit file uDisplay.cpp and remove // before this line to enable debug
//#define UDSP_DEBUG
and recompile

Rushmed · 2023-02-27T18:20:53Z

Compiled a tasmota32-lvgl.bin after installation no lifesign. No ap, no webinterface.
Do Ihave to compile tasmota32-lvgl.bin or something else to run on this S3?

Do I have to add something else to user config?

MiggyMan · 2023-11-15T23:57:35Z

@Rushmed did you ever get this working with the ILI9485/ESP32-8048S043 ?

Rushmed · 2023-11-16T18:08:18Z

Not really.

MiggyMan · 2023-11-16T21:54:55Z

I thought you might say that, i was kind of hoping to use the haspmota functionality in tasmota with one of these to replace openhasp since it has no support for deep sleep (making a remote :D)
