摘要
围绕液晶屏触摸控制器的控制方法,以液晶屏触摸控制器TSC2046为对象,讨论了软件控制触摸屏的编程特点。针对软件编程的缺点,设计了基于FPGA的触摸屏控制硬件实现IP核方案,并以ALETRA公司的FPGA为控制平台,验证了该设计方案。该IP核能够稳定、高速的管理触摸屏的触摸中断和坐标读取,节省了软件资源。
The paper focused on the commanding method of the LCD touch controller, and discussed the characteristics of the touch control software programming based on LCD touch control chip TSC2046. For the shortcomings of software programming, we present an IP core program of the LCD touch-screerl control hardware realization based on FPGA. The scheme was proved oll the FPGA platform of ALETRA Company. The IP core is stable and high-speed when it managed LCD touch interrupt and read coordinate, and it can also save the software resources.
