Looking to add a new display - JC3248W535 AXS15231

[Shadowtrance]

Looking add support for the JC3248W535 QSPI display i have here with the AXS15231 controller which is supported by Arduino_GFX.

Touch needs another lib for which bb_captouch works pretty well (with the #ifdef FUTURE flag disabled...apparently it's experimental, works fine for me). I honestly haven't found any other libs that support it.

So yeah just for tips on where to get started on doing so. :)

[MisterAG]

Yeah, I have two of these laying around as well. They would make excellent openhasp devices.
I gave it a shot to port openhasp to it, but I lack the coding skills unfortunately.

[Nokius]

Was thinkering this week on this. If it helps anyone to continue use it

[MisterAG]

I could compile and flash it, but it doesn't appear to work for me. I see the following below. Also serial over usb doesn't work, wifi neither.

[Nokius]

you are quite brave to give it a smoke test!

thanks for reporting what it looks like with the sometest.

I'm sure I over looked some stuff as the changes are very draft and need someone with more skill set to have. secound look.
The sources to get Arduino_GFX working on the board is this repo.

The lib is supporting the board.

[Nokius]

@MisterAG can try to build the code again and change the following values:

    -D TFT_WIDTH=480
    -D TFT_HEIGHT=320

[Nokius]

How did you try to get access to the usb serial? is there nothing showing up when booting the board?

[MisterAG]

Yeah, I already tried swapping the width and height since I thought perhaps it was writing out of bounds somewhere. But the image I get on the screen is identical as the photo I posted earlier.

I tried connecting over putty (tried different baudrates) and the arduino IDE since that auto reconnects. The terminal just sits there, there is no output, I can't input anything either like wifi credentials for example.

[MisterAG]

I cloned the official openhasp by the way and added your users setup.

[Nokius]

glad you where able to build it my branch keeps failing I assume you patched my cherry picks to get the build working can you share your code changes maybe?

[Shadowtrance]

I haven't messed with this display in ages (mainly due to it being a pain in the butt) but from what i can see with what you guys are tinkering with i think what you're missing is this display NEEDS the #define CANVAS part of the graphics config too to work correctly.

Arduino_DataBus *bus = new Arduino_ESP32QSPI(45 /* cs */, 47 /* sck */, 21 /* d0 */, 48 /* d1 */, 40 /* d2 */, 39 /* d3 */);
Arduino_AXS15231B *g = new Arduino_AXS15231B(bus, GFX_NOT_DEFINED /* RST */, 0 /* rotation */, false /* IPS */, 320 /* width */, 480 /* height */);
#define CANVAS
Arduino_Canvas *gfx = new Arduino_Canvas(320 /* width */, 480 /* height */, g, 0 /* output_x */, 0 /* output_y */, 1 /* rotation */);

And a gfx->flush(); in the setup if i remember correctly (possibly in loop too). Like in that video player example.

Also the touch driver isn't GT911 but the very same AXS15231B as the display as it's a 2 in 1 combo.

I may have a look at this further at some point.

[Nokius]

yes the trouch driver is wrong, and I'm not sure how to adjust this yet.

thanks for the canvas hint, I assumed that I miss that already will check how to get this sorted.
Thanks for your input!

I'm in a similar boat - I started playing a couple of weeks ago, and drafted this WIP discussion:

Waveshare ESP32-S3-Touch-LCD-3.49 / AXS15231B

Hi,

I've just picked up a ESP32-S3-Touch-LCD-3.49, which has:

• ESP32-S3 @ 240MHz
• A 3.49 inch touch screen, 172x640
• 8MB PSRAM and external 16MB Flash
• Display and touch driven by the AXS15231B, which runs on a QSPI bus.

Progress so far... I started out by getting ESPHome up and running, using the following config:

esphome:
  name: touch349
  friendly_name: touch3.49

    model: AXS15231
    id: main_display
    spi_id: quad_spi

      width: 176
    cs_pin: 9
    
    reset_pin: 21
    
    update_interval: 1s
    rotation: 90
    lambda: |-
      it.printf(20, 70, id(roboto), Color(255, 0, 0), id(ha_time).now().strftime("%I:%M:%S %p").c_str());
touchscreen:
  platform: axs15231
  id: my_touchscreen

I've started hacking together an OpenHasp ini file, and have got something on the screen, but have run into the following issues:

The driver looks to be included in ArduinoGfx, so I started down the route of adding code into src\drv\tft\tft_driver_arduinogfx.cpp

#elif(defined(AXS15231B_DRIVER))
    #warning Building for ESP32 ArduinoGfx AXS15231B_DRIVER
    // Arduino_DataBus* bus = new Arduino_ESP32QSPI(TFT_CS, TFT_SCK, TFT_D0, TFT_D1, TFT_D2, TFT_D3);
    // Arduino_GFX* g = new Arduino_AXS15231B(bus, TFT_RST, TFT_ROTATION, TFT_IPS);
    // tft = g;

    Arduino_DataBus *bus = new Arduino_ESP32QSPI(
        TFT_CS /* CS */, TFT_SCK /* SCK */, TFT_D0 /* D0 */, TFT_D1 /* D1 */, TFT_D2 /* D2 */, TFT_D3 /* D3 */);
    Arduino_GFX *g = new Arduino_AXS15231B(
        bus, TFT_RST /* RST */, 0 /* rotation */, false /* IPS */, TFT_WIDTH /* width */, TFT_HEIGHT /* height */,
        0 /* col offset 1 */, 0 /* row offset 1 */, 0 /* col offset 2 */, 0 /* row offset 2 */,
        axs15231b_180640_init_operations, sizeof(axs15231b_180640_init_operations));
    #define CANVAS
    Arduino_Canvas *gfx = new Arduino_Canvas(
        TFT_WIDTH /* width */, TFT_HEIGHT /* height */, g, 0 /* output_x */, 0 /* output_y */, 0 /* rotation */);

I tried to bump the version of ArduinoGfx, but haven't got too far.

Other findings:

• Hardware rotation appears to be broken.. Possibly need to set rotation after the touch driver is up...

Touch
This is also handled by the same AXS15231B chip, I've ignored it for now

[Nokius]

Nice to see you have start working on a board with a similar driver requested.
Yes the board JC3248W535 works well with esphome too.

I ported the driver see the commit in my branch. The touch driver is a mysterious for me. For now I happy to get the tft working :)

I checked the latest releases of ArduinoGfx to see if there was any AXS15231B related changes, as I found non I didn't look into the never version.

[Nokius]

This is the commit in ArduinoGfx to get the AXS15231B working.

[Shadowtrance]

The touch driver is going to need another library like bb_captouch (which needs a minor change to work or #define FUTURE...why that's there i don't know) or some other library that supports it.
I did just come across this though which is interesting.

[Nokius]

okay, getting out of my leak to get this lib ported and working. :-\
