Question

我有一个我不太了解的“神秘盒子”。我需要让Leonardo在BIOS设置中与盒子配合使用。我从GitHub（https://github.com/gdsports/usb-metamorph/tree/master/USBSerPassThruLine）下载了USBSerPassThruLine项目，该项目似乎可以与人类已知的所有BIOS设置一起使用，除了我的特殊包装盒。

每个按键都伴随一个隐式SHIFT。因此，如果我呼叫Keyboard.press（'a'），我会得到'A'。或者对于Keyboard.press（'3'）我得到'＃'。

我尝试使用自己的简单press（）例程尽可能直接：

The files belonging to this database system will be owned by user “postgres”.
This user must also own the server process.

The database cluster will be initialized with locale “en_US.utf8”.
The default database encoding has accordingly been set to “UTF8”.
The default text search configuration will be set to “english”.

Data page checksums are disabled.

fixing permissions on existing directory /var/lib/postgresql/data … ok
creating subdirectories … ok

selecting default shared_buffers … 128MB
selecting dynamic shared memory implementation … posix

WARNING: enabling “trust” authentication for local connections
You can change this by editing pg_hba.conf or using the option -A, or
–auth-local and --auth-host, the next time you run initdb.

Success. You can now start the database server using:

全部无济于事。

我仍然得到：'！@＃$％^'（而不是'123456'）

有什么想法吗？

顺便说一句，扼杀的是，此BIOS设置适用于我插入包装盒的任何USB键盘。这个盒子可以使用一些较旧的标准吗？

必须添加它才能使其正常工作：

   if (first_time) {

     first_time = 0;

     memset(&rawdata, 0x0, sizeof(KeyReport));

     rawdata.keys[0] = KEY_CAPSLOCK;
     sendReport(&rawdata);
     releaseAll();
     delay(100);

     rawdata.keys[0] = KEY_CAPSLOCK;
     sendReport(&rawdata);
     releaseAll();
     delay(100);

     rawdata.keys[0] = KEY_LEFTSHIFT;
     sendReport(&rawdata);
     releaseAll();
     delay(100);
   }

为什么这样有效？谁知道？

顺便说一句，这有零个东西来做Arduino开发板，以及所有与这个p.o.s有关的事情。框。
