Hi Artur,
there you have done nice work - but it is "double" ::) We are already working on a PCB that connects those LCDs in parallel mode...
These PCB will carry bare LCD and serves 2mm header and 2.54mm header. It must carry touchscreen components, too. Formfactor of 3.5" LCD (only panel) is exactly matching formfactor of "old" 3.2" LCD with PCB...

Hi Artur,
looks nice - but I cannot tell you if everything is correct and / or working. And I cannot spend time in doing this ::)
The best way would be to produce one and give it a try!
Our PCB is finished and will not be changed (expect if faults are present).
What software did you use for designing PCB?

Very interesting for Windows-users! Price is absolute ok and if you do not have problems using closed-source software it is great.
I am using KiCAD on Linux.

That is a tool for taking existing PCBs as draw ::)
It makes it easy to integrate existing into new.

...wobei sich das Layout des LCDs bei 3.5" deutlich verändern wird. Dieses LCD kann eine Auflösung von 480x320 darstellen im Gegensatz zu den kleineren, die nur 320x240 darstellen können.
Auf den Fotos kommt der gefühlte Größenunterschied längst nicht so zur Geltung wie in Realität. Schon der Sprung von 2.8 auf 3.2 war ein erheblicher Gewinn, und der auf 3.5 ist nochmal ein gewaltiger. So kann man auf dem 3.5er Wasserfall und Spektrum GLEICHZEITIG darstellen.

oh ja - da freue ich mich schon drauf!
Andreas, wird es eine "DF8OE" Adapterplatine für das 3,5" Display geben?
Habt ihr/Du da was geplant?
Das weiter oben geschriebene verstehe ich mangels guten Englischkenntnissen nicht so 100% :-\ |

Hallo Thomas,
es wird ein 3.5" LCD geben, das Plug&Play kompatibel zu unserem 3.2" und dem 2.8" vom mcHF ist. Das LCD wird parallel angesteuert und hat exakt den gleichen Formfaktor wie das 3.2". Die PCB machen Slawek SP9BSL und ich zusammen. Die LCDs werden rechtzeitig zum Start der UI-Auslieferung verfügbar sein. Ob bis dahin aber das neue Layout das wegen der anderen Auflösung nötig ist bereits fertig ist weiß ich noch nicht. Da ist Slawek dran - ich teste "nur".

super!
ich bin fest davon überzeugt dass das 3,5" gut angenommen und zum Standard für den OVI40 wird. |

Hi,
the adapter board is under "heavy" development, i think i will have its alfa release by home brewing at end of this week.

very nice Artur, but it seems it's only for a spi version of the PI display.
Andreas prefers parallel bus in the OVI40 project.
Is there a support for spi bus?
I don't know ::) |

| Yes, there is support for SPI with new lcd but we are testing it. Now preparing also for parallel interface tests. |

If there is a possibility to use parallel instead it is a very good idea to do this. At mcHF there is from the beginning a lack of free GPIOs so SPI is useful there. At OVI40 there is 144p package of MCU and enough free GPIOs to drive LCD in parallel and do have much free GPIOs for other purposes.

even for mchf i prefer parallel (no need for clock)
when the parallel is available i would like to try it on my mchf |

On mcHF you have to kick off freedv and possibly more because of mcHF is out-of-RAM with 480x320 and additionally some new nice UHSDR features.
