== Summary ==
The 7-inch IPS display with resistive touch and 1024×600 resolution connects to a Raspberry Pi via HDMI. The guide covers hardware connection, system images, touch calibration, and rotation on Bookworm, Bullseye/Kali, and Ubuntu.

== Technical overview ==
* 7-inch IPS panel with a fixed hardware resolution of 1024 × 600 pixels.
* Resistive touch panel; the touch function requires GPIO connections while video output is over HDMI.
* Compatible with all Raspberry Pi revisions; Zero and Zero 2 W require an additional HDMI cable.
* Supports Raspberry Pi OS (Bookworm), Ubuntu, Kali, and RetroPie; on other systems it can be used as a regular HDMI monitor, in which case touch is unavailable.
* Hardware connection: align the 26-pin ribbon connector with the Pi's 40 GPIO pins and connect the HDMI cable between the Pi and the display.
* For configuration files, add the output lines hdmi_group=2, hdmi_mode=87, and hdmi_cvt 1024 600 60 6 0 0 0 to /boot/config.txt (or /boot/firmware/config.txt on newer systems).
* Additionally, enable the waveshare-ads7846 device-tree overlay with parameters penirq=25, xmin=3900, xmax=200, ymin=200, ymax=3900, speed=50000, swapxy.
* File names and paths may vary by OS version; calibration requires measuring actual boundary values using evtest.
* Rotation on Bookworm is done through the screen configuration app or Wayfire settings; older X-based systems use xrandr -o or display_rotate in config.txt.
* When used as a plain monitor without touch, rotation must be controlled through the desktop environment or kernel parameters.

== Notes and version constraints ==
* The exact paths for config.txt and overlays differ across Raspberry Pi OS versions; verify the current directory structure before editing.
* The calibration values given are example measurements from one specific device; your own boundary values must be determined with evtest.
* Axis swapping (swapxy) and the pen IRQ number are device-specific; changes may disrupt touch functionality.
* The rotation commands apply only to the listed operating-system variants; other distributions may require different mechanisms.
* The source contains placeholders and incomplete sections; missing details require manual confirmation by a technician.
