器件型号：MSP430FR2633 主题中讨论的其他器件：CAPTIVATE-PHONE、
您好！
我将 MSP430FR2633 TSSOP 封装控制器用于触摸板的16元件键盘传感器。 我将互电容技术用于此目的。 我遵循 了 CAPTIVATE-PHONE 的硬件布局设计。 虽然我能够检测到键盘上的手指触摸、但我观察到、在频繁触摸键盘元件时、突然停止了触摸检测。 但是、在等待几秒钟后、它会开始检测。 我还观察到、当我将手指放在键盘元件附近时、它会每次检测到触摸。 仅当与键盘元件直接接触时、触摸检测才会停止。 键盘元件上没有覆盖材料。 请帮助。 以下是我通过设计中心工具生成的 captouch 配置。
