hp hid compliant touch screen driver

I recently made a device driver for the 2.6.13 kernel and now wrote it to the "Touch Screen". My reference method is as follows:(Let's take a look)The S3C2410 driver is not provided in linux2.6.14, so we need to create a new driver file.Create a new hfrk_s3c2410_ts.c file in

Linux-2.6.26.5 transplantation LCD Driver LCD touch screen driver tslib-1.4 Before using tslib, your kernel must have an LCD driver and a touch screen

The Touch Screen driver is not implemented using the input subsystem. In fact, it is not much different from the driver of a common character device. You only need to follow the touch screen steps. ① S3c2410_ts_init function, whic

Recently, a touch function has been added to the company's products. Because the circuit has been finalized and only the USB interface has been introduced, we can only use the touch screen of the USB interface on the market and have contacted a number of touch screen agents,

I. MX6Q (TQIMX6Q/TQE9) Study Notes-New BSP touch screen driver porting, tqimx6qtqe9 The reason is that the driver has been transplanted on the TQ210 and AM335x platforms. Therefore, the driver can be transplanted to imx6q with only a few modifications. Start to

Design of S3C2440 resistive touch screen driver Experiment: When the pen clicks on the touch screen, SecureCRT displays the X and Y coordinates of the contacts; Objective: To test the resistance touch

To port the MDD layer of the touch screen driver to the drivers folder of the BSP package, we need to figure out how to compile and generate tchmain.
