== Summary ==
Technical guide for the 10.1-inch IPS display (1024×600) with HDMI interface and resistive touch, designed for Raspberry Pi.

* [https://shop.jw-tech.eu/p/WSAL11870 WSAL11870 – 10.1inch Resistive Touch Screen LCD, 1024×600, HDMI, IPS, Supports Raspberry Pi / PC]

== Technical overview ==
* The panel is a 10.1-inch IPS display with a resolution of 1024 × 600 pixels.
* Screen output is provided via the HDMI input; the touch area additionally requires GPIO connections to the Raspberry Pi.
* The Raspberry Pi exposes 40 GPIO pins while the screen exposes 26 pins; pin mapping must be observed when connecting.
* Raspberry Pi Zero / Zero 2 W requires an additional HDMI cable because direct connection is not possible.
* In config.txt, add the lines hdmi_group=2, hdmi_mode=87, and hdmi_cvt 1024 600 60 6 0 0.
* To enable touch, use the overlay waveshare-ads7846, setting parameters such as penirq, xmin/xmax, ymin/ymax, speed, and swapxy.
* Copy the file waveshare-ads7846.dtbo into the /boot/overlays/ directory.
* Touch-area calibration is performed using evtest by adjusting the limits x_min, x_max, y_min, and y_max according to actual measured values.
* Depending on the operating system, several methods are available for rotating the screen: via Screen Configuration under Bookworm, via xrandr or display_rotate under Bullseye/Kali, and via cmdline.txt under Ubuntu.
* On Ubuntu, display rotation during command-line startup can be controlled through entries in /boot/firmware/cmdline.txt.

== Notes and version constraints ==
* The exact values for touch calibration are device-specific and must be determined individually using evtest.
* The method for screen rotation depends on the specific operating system and its version; the current environment should be checked before modifying configuration.
* Whether the KMS or FKMS driver is loaded affects which rotation commands are available; this must be verified before applying them.
* The referenced .deb packages are version-specific; ensure they are compatible with the installed system.
* Statements about power consumption (550 mA with backlight on, 100 mA with backlight off) and operating temperature (0°C to 70°C) come from the FAQ and should be confirmed before use in critical environments.
