HID键盘问题，求助大神

dczn*** · 发表于 3 天前

最近用STC32G12K64做HID键盘的主控，用官方的标准键盘实例。做出来的键盘和电脑的标准键盘在电脑上面测试基本一致。但是在一些数控设备上面测试，发现用STC32G12K64做HID键盘主控的键盘出现很多问题，比如数控系统插上标准的HID键盘的时候，按26个字母按键，屏幕显示的是大写字母。用STC32G12K64做HID键盘主控的键盘按26个字母的时候，全部显示小写。标准的键盘按SHIFT按脚的时候，数控系统的光标会显示，用STC32G12K64做HID键盘主控的键盘按SHIFT按脚到时候，数控系统画面没有反应，但是shift按脚功能是有效的。还有一些数字按键在数控系统显示的也是不正确的。用STC32G12K64做HID键盘主控的键盘的键值都和标准的HID键盘比对过，都是完全正确的。可是在数控系统上面显示却不一样。

不知道是不是功能按键这部分在初始化到时候有什么差异？

下面是单片机的USB初始化部分几乎没有修改，只是添加了键盘扫描和按键排序
