工具/软件：
您好：
CapTIvate 技术指南介绍了一种在触摸时点亮 LED 的方法。
我们有一位客户请求使用触摸板实现此功能。
是否有成功实现这一目标的示例或案例？

您好 DDdoor 
好的、如果我理解这个问题、当触摸板“触摸“时点亮 LED 的软件与任何其他类型的传感器相同、例如按钮。
如果是这种情况、我已经上传您在 CapTIvate 技术指南中看到的远程设备的示例代码（您在上面提供的第二个链接）。
此代码位于“trackpad_remote_demo.c 文件（位于附加的.zip 文件中）“中。 为了方便,我也发布了下面的代码. 具体从第 82 行开始。
/*

* This file contains the sensor callbacks, UART and slave I2C communications handler
* to support communications with host.
* Note: See the modification to CAPT_commConfig.h on line #84 to enable both I2C and UART

希望这有所帮助。
