RPI: make a desktop GUI app ( QT6 C++ / Py )

while RPI is known for learn Linux and start coding
from the beginning that real
desktop app programming / GUI
comes short or, for more easy start, begins with 'PyGame' ...

and i was in exact same situation a decade ago...
in the meantime i try to stay up to date
learn / teach
* web development
* micro controller ( add web server and data handling like mqtt )

and actually lost track on what had happened on the real app development front..
but sure noticed that some things have changed
like now for RPI OS 64bit on my RPI4 use
* OS: Debian GNU/Linux 13 (trixie) aarch64
* Kernel: Linux 6.12.62+rpt-rpi-v8
* WM: labwc (Wayland)
* Theme: gtk2 [Qt]

RPI OS Linux? support default QT5? or even QT6?

i did a test to show a picture of RPI SCRATCH Deutsch
post
to say that even NON ENGLISH native kids can start learn coding early
( as usually need learn english first / means they are 5 years late ! )

Micro Controller

Open PLC for microcontroller

even i work in Industrial Automation and Instrumentation ( and Electric )
( using so called Process Control Systems )
that what you think of
PLC Programmable Logic Controller
was never my thing,
but sure, some subcontractor used them and we linked them into the PCS via Modbus

try RPI PICO 2 W

you possibly come from here
about a project:
ARDUINO IDE / PICO W / WEBSERVER / MQTT NO TLS / NodeRed trend & DB & operation / 4 Relay board /
where i also try same code on the ESP32S3

revive NODE MCU ESP32s & Arduino IDE 2

test if i could run my current big project from ESP32S3 also on a ESP32
i try on that, even after jumper the cpu temperature thing ended in kernel panic auto reboot

but i noticed that this ESP32 i have, has 2 DAC pins ( Analog OUT )
a rare feature i want use.
