摘 要: | 对触点位置坐标识别与输入是触摸液晶屏的重要功能。由于SOPC Builder系统没有提供TRDB-LTM触摸屏的驱动,因而提出了一种基于Avalon总线的TRDB-LTM触控IP核的设计方法。实现TRDB-LTM触控屏触碰位置坐标的准确录入。给出系统硬、软件设计过程。经测试,所设计的IP核能够准确快速的识别触碰位置坐标,工作稳定可靠。

Abstract: | Identifying the position coordinates of the touch input is an important feature of the touch screen.As the SOPC Builder system does not provide TRDB-LTM touchscreen driver, a TRDB-LTM touch control IP core based on Nios II design method is proposed.The coordinates of the touch point were identified correctly.Provlded both the hardware and software design process.According to the test, the IP core designed by this method can be quickly and accurately identify, the touch location coordinates, runs stable and reliable. |
