使用Arduino Leonardo的通用键盘仿真

arduino

使用Arduino Leonardo的通用键盘仿真,arduino,hid,emulation,Arduino,Hid,Emulation,我正在尝试使用一个用于键盘模拟的，因为这是它的广告特性之一。我一直在玩莱昂纳多，并根据眨眼的例子写了一个非常简单的草图 //针脚13在大多数Arduino板上都连接了一个LED。 int led=13； //按“重置”时，设置例程运行一次：无效设置（） { //将数字管脚初始化为输出。引脚模式（led，输出）； } //循环例程会一直反复运行： void循环（） { 延迟（5000）；//等待五秒钟数码写入（led，高）；//打开led（高是电压电平）延迟（100）；//等待一秒钟 di

我正在尝试使用一个用于键盘模拟的，因为这是它的广告特性之一。我一直在玩莱昂纳多，并根据眨眼的例子写了一个非常简单的草图

//针脚13在大多数Arduino板上都连接了一个LED。
int led=13；
//按“重置”时，设置例程运行一次：
无效设置（）
{
//将数字管脚初始化为输出。
引脚模式（led，输出）；
}
//循环例程会一直反复运行：
void循环（）
{
延迟（5000）；//等待五秒钟
数码写入（led，高）；//打开led（高是电压电平）
延迟（100）；//等待一秒钟
digitalWrite（led，低）；//通过降低电压关闭led
Keyboard.write（'A'）；//使用键盘仿真器编写A
}

现在，这个例子在我的Windows XP机器上非常有效。它被认为是一个通用键盘，每五秒钟会键入一个“a”

目标环境正在运行DOS，因此据我所知，我需要让这台机器上的BIOS识别Arduino Leonardo，它不是，也不会在DOS中键入“A”

我一直在修改Leonardo的USB设备描述符，试图使其尽可能与Dell L100匹配。我所做的修改没有帮助，我怀疑这是因为Leonardo是一个复合设备，它在同一个USB端口上公开了串行通信、键盘模拟和鼠标模拟。USB描述符/配置的源代码可编辑，位于：

Arduino\u安装\hardware\Arduino\cores\Arduino\HID.cpp
Arduino\u安装\hardware\Arduino\cores\Arduino\USBDesc.h
Arduino\u安装\hardware\Arduino\cores\Arduino\USBCore.h
Arduino\u安装\hardware\Arduino\cores\Arduino\USBCore.cpp

以下是用于Leonardo的USB设备查看器的转储文件：

我怎样才能让BIOS将这个Leonardo识别为通用键盘呢？

我可能弄错了，但是如果你想在引导过程中识别你的设备，它的

bInterfaceSubClass

应该是0x01（引导设备子类）。在您指出的源文件中，到处都有设置为0x00的子类

你可以试着设置一个
