STC8H8K64U把电容触摸I2C转成USB信号-多点问题
2023-2-5 23:06 来自 Gavin 发布 @ 综合讨论
各位大佬，用STC8H8K遇到如下问题，有了解的帮忙提供下解决思路，有参考例程的最好了，谢谢！背景：基于STC8 USB 鼠标例程已经调通触摸屏单点触控，需求是实现触摸屏I2C转USB 多点触控（支持5指或10指）问题：在单点触控程序基础上主要修改HID Report Descriptor，Win7上USBLyzer上可以收到触摸屏上的坐标数据（上图以2指触控为例），但只能识别一指划线效果，切换到Win11上表现为完全无反应（装USBLyzer后USB无法抓数据，因此未测此时USB数据）
