🧠 跟你电商上看到的“支持Xinput/DirectInput、免驱、直接识别为摇杆”功能已经 完全对齐! 🧱 接下来你可以做的扩展(街机方向): 扩展项 做法 加更多按钮 修改HID 报告描述符,支持16/32按钮 加方向摇杆 加入X/Y轴定义,占用 2 字节报告 加旋钮(模拟轴) 使用ADC 输入,加入 Analog usage 加灯光/震动 用GPI...
① 模拟输入引脚是带有ADC(Analog-to-Digital Converter,模数转换器)功能的引脚。 ②它可以将外部输入的模拟信号转换为芯片运算时可以识别的数字信号,从而实现读入模拟值的功能。 ③模拟输入功能需要使用analogRead() 函数。 参数:参数pin是指定要读取模拟值的引脚,被指定的引脚必须是模拟输入引脚。如analogRead(A0),即...
