Module ESP32-2432S integrated with Annex

[cicciocb]

Hi all,
I have completed the Annex32 support for the ESP32-2432S028 module (and it should also work with other members of the ESP32-2432xxxx family).
The support is complete, including the TFT, touchscreen, and SDCARD.

The designated display is supposed to be an ILI9341, but in my case, it turned out to be an ST7789 #5.

You can flash the finalized version, Annex32 CAN 1.516, which includes the support, using the web flasher as usual.

this Demo works perfectly:

Do not forget to calibrate the touchscreen typing
touch.calib
in the immediate window

Good morning Francesco
That's good news, I'll test it thoroughly later.
Thank you for the quick integration of the module.
Kind regards,
Monki

Super, thankyou
here my Pin Config and at first Line i write

Code: [Local Link Removed for Guests]

TOUCH.CALIB

and for switch off the LED's

PIN.MODE 16, input
PIN.MODE 17, input
PIN.MODE 4, input

But if i save my File incl my input with a new name, it didn't save......

You must just select the version like that:

DOn't need to set the pins, all is automatic.

The touch calib must be done just one time, so use the immediate window once

No, for my TFT is ILI9341 the best ST7798#5 is not my, then it is inverse

[cicciocb]

Yes, It seems that there are different versions of the TFT. You should try the SD card too

Hello,
I tested the system extensively yesterday. It works very well on my two modules, one bought from aliexpress and one from Amazon. Both work with the configuration for the IL9341 display without any problems. The SD card function works with 3 tested cards (4GB, 16GB .32GB) perfectly.
Thanks again to Francesco

Yesterday I received my AliExpress ESP32 2432S028 module, identical to the one you show in the photo.
I followed your instructions and loaded Annex32 CAN 1.51.6 LFS first and then 1.51.7.
In both cases it works perfectly by choosing the ESP32-2432S module and the ST7789#5 TFT Display. It recognizes the SD card without problems and runs graphics programs and GUIs.
But... (And there is always a but) As for the touch, it does not allow calibration, it responds to the first cross but not to the following ones. However, by pressing (3) several times on the text "TOUCH AND HOLD", you advance from cross to cross until the blue screen of "CALIBRATION OK!"
Then, in a normal program, it does not respond to touch except in a very small area of the screen, 210 mm wide by 250 mm high in the upper left area.

I'm almost sure it's defective, but can you think of anything to try before trying to return it?
It cost me €12.99 and I will probably keep it for use without touch. The seller has had me on hold for hours and I don't really feel like, for that amount, getting involved in returning packages and then claiming expenses.

The resistive touch are really not very reliable and, in general, must be used with the little pen (delivered with the module) and pushed with a little bit of force. (not with a simple touch as is the case for the capacitive one)
You can try to align again HOLDING the pen in the cross position pushing with a little bit of force.

But, again, I found big differences between the resistive touch screen, most of time is question of good chance .... in my case, for this module, it works quite well.

I think I've tried everything, including strength.
The touch layer looks like it is damaged.
And really, it is not known if it is resistive or capacitive, since it only says ESP32-2432S028, without the letter R(esistive), C(apacitive) or N (No touch).
But it is a nice and very compact model. I will use it for graphics only.
