ELECTRIC CAPACITY TOUCH SCREEN DRIVER DEVELOPMENT FOR EMBEDDED SYSTEMS
摘要
Abstract
Take Freescale Semiconductor's MX51 as hardware platform, the multi-touch capacilive louch screen implementation solution in embedded systems is presented. The touch screen data are sampled by PIXCIR ATmegal68 chip. Then these data are processed and transferred into the system along I2C bus. By handling the input sub-system, interruption, queue and other technologies in Linux, the procedure and method of developing caparitive touch screen driver on Linux 2. 61.31 core is discussed in detail. The design applies well to smart phones, MID, and netbooks.关键词
