* [https://shop.jw-tech.eu/p/WSAL18396 WSAL18396 – 5inch Capacitive Touch Display for Raspberry Pi, DSI Interface, 800×480]<br />
<br />
== Technical overview ==<br />
* 5-inch capacitive touch panel, resolution 800×480, hardened glass rated up to 6H.<br />
* Supports 5-point touch input.<br />
* DSI interface connects directly to the Raspberry Pi; refresh rate up to 60 Hz.<br />
* Compatible with Pi 5/CM4/CM3+/CM3 via a 22-pin DSI1 cable; older models (Pi 4B/3B+/3A+/3B/2B/B+/A+) use the 15-pin DSI interface with an FFC cable.<br />
* Pinout: DSI data pairs DSI1_DP0/DN0 and DSI1_DP1/DN1, clock DSI1_CP/CN, I²C0 (SCL0/SDA0), 3V3 supply and GND.<br />
* Software setup via config.txt: add dtoverlay=vc4-kms-v3d and either dtoverlay=vc4-kms-dsi-7inch (DSI1) or dtoverlay=vc4-kms-dsi-7inch,dsi0 (Pi5/CM4 only).<br />
* Backlight brightness adjustable from the terminal via /sys/class/backlight/*/brightness (value 0–255).<br />
* Display rotation via GUI (Trixie/Bookworm) or cmdline.txt: video=DSI-1:800x480M@60,rotate=90/180/270.<br />
<br />
'''Commands and examples – verify before use:''' <br />
<syntaxhighlight lang="text"><br />
dtoverlay=vc4-kms-v3d<br />
dtoverlay=vc4-kms-dsi-7inch<br />
dtoverlay=vc4-kms-dsi-7inch,dsi0<br />
echo X | sudo tee /sys/class/backlight/*/brightness<br />
video=DSI-1:800x480M@60,rotate=90<br />
sudo apt-get update<br />
sudo apt-get full-upgrade -y<br />
sudo reboot<br />
</syntaxhighlight><br />
<br />
== Notes and version constraints ==<br />
* Exact compatibility depends on the Raspberry Pi model; for Pi5/CM4 you must choose between DSI0 and DSI1.<br />
* Individual steps are version-sensitive (Trixie vs. Bookworm vs. Bullseye/Buster); verify the current OS version before applying.<br />
* Terminal-based brightness control requires write access to /sys/class/backlight.<br />
* Knock-off products may cause functional issues; use the genuine product with part number WSAL18396.<br />
* For older systems (Stretch/Jessie) a different rotation method applies; not all listed commands are universally valid.<br />
