Hello all, hoping I can get some help with this. I reached out on Discord but could not get it figured out from that info.

I currently have a Lolin D32 Pro V2 and a ILI9488. I have installed the Tasmota32-lvgl version on the board and wired the ILI9488 according to this guide https://www.instructables.com/ILI9341-Display-and-LOLIN-D32-Carrier-Board/ I set my gpio config to this

and I added the display.ini with the example from here
https://github.com/arendst/Tasmota/blob/development/tasmota/displaydesc/ILI9488_XPT2046_display.ini

When I boot up I am able to get a blue screen with tasmota logo on it. I followed the guide here to do the calibration
https://tasmota.github.io/docs/LVGL/#calibrate-a-resitive-touch-screen
and I am able to get the screen to show, but no touch is working.

This is the Lolin I purchased

This is the ILI9488 I purchased (4.0 in with touch)

Did you make sure that the SPI bus pins for the XPT2046 touch chip is connected to the SPI bus pins for the display as such? Of course, along with the T_CS pin connected to the gpio you picked.

When I ask, it is due to having the experience that "wired according to" sometimes may not be the "full story", and your specifification of gpio 16 for touch does not match the drawing I saw. Not that it has to, but it gets hard to guess what wiring you actually have.

And preferably, gpio 16/17 are ones I'd avoid unless other pins are taken, due to the pins being used for PSRAM. It may not be much of a conflict, or cause errors, but I like clear separation.

Did you get the DisplayCalibrate crosshairs on the screen?

(For readable logs, better wrap in triple backtick lines, before/after).

Do you see any issues with my config? or is no one using this setup yet?

sfromis Feb 1, 2024

It looks just like what I'm doing with a very similar ILI9341 based module.
Almost same layout and pin labels, except for DC matching DC/RS on yours. IDK if/what that might imply, if anything.

However, I notice that the pin traces around the XPT2046 chip itself are different with the ILI9488, with your image showing 4 traces connecting to vias, while the same 4 are unconnected on my board, and a couple of traces connecting to small SMD components. Strictly speaking, I can't tell if those 4 might be connected under the chip, but that would be a bit unusual on a board with so much free space.

My recorded pin connections from the display module, matching yours (except for different gpios which I see no significance in) are:

    VCC       - 3.3V
    GND       - GND
    CS        - IO0  = SPI CS
    RESET     - IO1  = Display Rst
    DC        - IO2  = SPI DC
    SDI/MOSI  - IO11 = SPI MOSI
    SCK       - IO12 = SPI CLK
    LED       - IO5  = Backlight
    SDO/MISO  - IO13 = SPI MISO
    T_CLK     - SCK
    T_CS      - IO8  = XPT2026 CS
    T_DIN     - MOSI
    T_DO      - MISO
    T_IRQ     - (none)

BTW. If you used the Lolin/Wemos TFT 2.4 Touch Shield (with ILI9341), it would be as easy as plugging in a connecting cable, as your D32 Pro is specifically designed for that. That shield also allow for plugging a S3 Mini (or the "less preferable" S2 Mini) directly into the back, without needing any cables other than for power. Almost too easy, then you just need a template to match the pinout. I have all 3 combinations working, including touch; just had to make calibration work which became a bit of a challenge.

Of course, this not to imply that it should not be perfectly workable with your "less easy" ILI9488 board (like with my similar ILI9341 board), but you need great care in wiring, including making sure that every wire and connection works stably. With those dupont wires, issues are not at all uncommon, they are really not great for reliable operation.

Had exactly the same problem.
Remove MISO wiring form the display (leave DO for the touch)
Replace:
:TS,21
with:
:TS,*,-1,0
Try using it without calibration the display.
Have Fun :)
