This document provides a step-by-step guide for porting and calibrating the TSC2007 resistive touchscreen controller on the Forlinx OKMX8MP-C development board running Linux kernel 5.4.70.
Purpose: Help developers enable and configure the TSC2007 driver so that resistive touchscreens can work properly on the OKMX8MP platform.
Scope: Applicable to Forlinx OKMX8MP boards with Linux 5.4.70 SDK.
Prerequisites: A working Linux build environment, basic knowledge of device tree modification, and hardware equipped with a TSC2007-based resistive touchscreen.
The TSC2007 is a low-power resistive touchscreen controller launched by Texas Instruments (TI). It adopts a 4-wire interface, integrates a 12-bit Analog-to-Digital Converter (ADC), and features an I²C communication interface, supporting a wide voltage range from 1.2V to 3.6V.
