HID USB控制传输(Windows)

hidapi hid usb windows c++

Teddy · 技术社区 · 7 年前

最近,我开始学习如何在Windows10上与HID设备通信。

但我有几个问题。

根据窗口的文档, HidD_SetOutputReport 必须设置 ReportBuffer 报表ID的参数,或 0x00 .

由于我的设备的HID报告描述符已经声明了一些报告id,因此我必须在使用时设置报告id HidD_setoutputreport 而不是 0x00 ?

当我使用报告id 0x80作为 buf[0] ,例如:0x80 0x02 0x00。。。。。。。0x00(车型年款 Capabilities.OutputReportByteLength 是64)

我的代码是 ret = HidD_SetOutputReport(handle->device_handle, buf2, 65)

但我总是这样发送数据(在 Bus Hound ):

64出80 02 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 ................ 4.1.0 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 ................ 4.1.16

00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 ................ 4.1.32

00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 ................ 4.1.48

我想它应该 buf[1] to buf[64] 而不是 buf[0] to buf[63] ,所以我试过了 ret = HidD_SetOutputReport(handle->device_handle, buf2, 64) ,但结果相同。

以下是我的输入和输出HID报告描述符:

我真的无法对Windows API发表评论(我从未使用过),但我知道如果在HID报告描述符中指定报告id 然后,报告id占用数据包的第一个字节和其余字节数据包的有效载荷是您的有效载荷,否则您的数据包就是所有有效载荷,并且未发送REPORT\u ID。在您的情况下,您的RD指定一个REPORT\u ID和 63字节的有效负载,因此我将指定长度为64,并将第一个字节中的REPORT\u ID。

报告id被传输到端点,以便它知道如何解释每份报告

我已经检查了你的报告描述,我可以建议一些调整,可能会减少未来悲伤的机会。

从输入报告中删除52字节的pad。无论如何,它只会被主机忽略,因此无需从您的设备发送。
使用较短的使用代码来减小报表描述符的大小。如果您的设备内存不足,这可能很重要。
不需要时重置物理单元。如果不这样做,则物理单位将应用于所有后续项目-这可能不合适(例如,长度以英寸为单位的开/关开关)。我通过使用PUSH来保存全局变量,并在以后方便的时候使用POP来恢复它们,从而完成了这项工作。
在输出报告中指定数据(非常量)。我真的不确定这是否有什么区别,但你永远不知道,未来的一些USB驱动程序可能会选择在发送数据包之前将任何常量字段设置为null,这会造成痛苦。

执行上述操作后,报告描述符大小从203字节减少到仅133字节:
