（Guitar电容屏驱动）多点电容式触摸屏控制芯片Guitar，采用投

射式电容检测原理，由15个驱动通道与10个感应

通道组成触摸检测网络，通过内置模拟放大电路、

数字运算模块，及高性能MPU得到实时准确的触

摸信息，并通过I2C传输给主控芯片。实现“所

点即所得”的非凡用户体验。

Guitar可同时识别5个触摸点位的实时准确

位置，移动轨迹及触摸力度。并可根据主控需

要，读取相应点数的触摸信息。-(Guitar capacitive screen driver) multi-point capacitive touch screen controller chip Guitar, using cast

Shot capacitive detection principle by 15 and 10 drive channel induction

Channel composed of touch detection network, through built-in analog amplifier circuit,

Digital computing modules, and high-performance MPU get real-time accurate touch

Touch information, and transmitted to the master chip via I2C. Achieve　the

Click-to-income　extraordinary user experience.

Guitar can identify five touch points in real-time accurate

Position, the movement trajectory and strength of touch. And in accordance with the master need

To read the information of the corresponding touch points.
