asus touch screen driver

Some time ago, the touch screen and the Optical Mouse responsible for the project were all input devices. After reading the materials and combining the project code, I made a summary, which basically came from my personal understanding and the Internet. After linux2.6, Linux abstracts the input device and abstracts the input subsystem, which is the middle layer driven by all I/O devices, provides a unified

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
