Hi guys,
some time ago Michael asked about a lcd board for 4inch lcd for OVI40 UI. Although my answer is related to OV I40 UI but not directly to Helmut's opening message of this thread, I can say: well, there is no need for separate board nor modify existing one if one may agree to some disadvantages. Look bellow please at our ordinary 3.5" lcd board with 4 inch lcd, there is no workarounds needed. One of the lcds available on Aliexpress exactly fits. Just remove the 3.5" lcd and insert new one. As you may see the lcd is quite big and almost collides with the knobs, but it is possible to put it there if one wants it.

The object on Aliexpress:
https://www.aliexpress.com/item/4000817659016.html?spm=a2g0s.9042311.0.0.2ff75c0fyXW9bl

Please be careful when ordering, select the "SILI9486 touch" !

Hallo, Bestückungsdruck gibt es keinen, ich bestücke nur nach dem Bestückungdplan...
Bevor man große Stückzahlen bestellt, würde ich ein paar Musterplatinen bestellen, da die Printversion mit der 34-poligen Leiste noch nicht ausgetestet ist...

Hi Slawek !

Looks "The object on Aliexpress:" is not available with the ILI 9486 controller anymore.
Do you maybe have an alternative where to order those compatible 4.0" LCDs ??

Hi Peter,
I'm very busy but somehow things go in right direction..

Of course I have an alternative, plenty of them on Ali (at least until "someone" will buy all of them for own business after this info
There is LCD from the same seller but marked as "ST7796 touch".
Give me few days until I add new driver to official firmware:



As stated before here, the 4" lcd is so big that freq knob overlaps it partially, I've designed special board for few types of 4" and one 3.5" with removed support for mcHF. Since Chris decided to remove parallel conection from 6.3 boards the connectors are not needed anymore. The additional small break-off board moves the freq knob out of lcd area:

I'm looking forward to binding the ST7796 controller in the firmware. It is very close to ILI9486 in datasheet specification. Thanks for your work, 73!

I still look forward to the ST7796 driver in the source code of the UHSDR firmware. There is a ready-made debugged 4 "transceiver, there is a 4" display with this controller. I really want to marry them )).

Hi,
recently there was huge change in display driver code, I must (and want to) follow that beacuse I'm a part of the team. You abandoned the teamwork within UHSDR project so my advice to you is: you have to wait.

Sure.

Slavek SP9BSL, hello. Can you share the firmware source code for the ST7796 driver with me? Is it possible? I'll deal with the driver myself, time is expensive. 73!

Code is available in my repo since few months. I'm suprised you did not checked that. Look there and check commits in directsampling-dev branch, this is our main construction site now. Next some updates will be pulled to active-devel too.

There is no ST7796 controller driver in the directsampling-dev and sparke_integration repositories. I need help.
