The driver is designed based on an Arduino implementation marked as under MIT License. This driver is written for a particular round display based on the CST816S controller, which is not compatiable with existing driver for Hynitron controllers.

Input: add Himax HX852x(ES) touchscreen driver 2025-09-17T21:44:02+00:00 Stephan Gerhold stephan@gerhold.net 2025-09-17T21:11:32+00:00 09fd8626cf8285503b4803b30b06c296599a24e7 Add a simple driver for the Himax HX852x(ES) touch panel controller, with support for multi-touch and capacitive touch keys. The driver is somewhat based on sample code from Himax. However, that code was rather confusing, so that we spent a significant amount of time just trying to understand the packet format and register commands. In this driver they are described with clean structs and defines rather than magic numbers and offset calculations.
