  * The caps-lock key is handled by the keyboard, which means it send a "key pressed" event when it is enabled and a "key released" even when it is disabled. However, the PC wants to get "pressed then released" at both times. So we have to cheat and build up events for this key.
  * Some keys on the amiga keyboard doesn't exist on the pc. We remap Help to F12, and \| (azerty) on F11. There are others, more suitable keycodes for them in HID (there is a help keycode for example) but Windows doesn't handle them.

+== Upgrading the firmware ==
+
+Here are instructions on how to upgrade the firmware :
+ * You need a PC with windows or linux, or another OS that can run avrdude.
+ * You need another keyboard to control the computer while the adapter is in upgrade mode
+ * You need AVRDude ( http://savannah.nongnu.org/projects/avrdude ) or another software that can handle 'usbasp' programming
+ * You need the latest firmware .hex file
+
+Now how to actually do it :
+ * Unplug the adapter from the computer
+ * Open the adapter
+ * Inside there is a jumper, when the jumper is closed te adpater will enter upgrade mode, when it is open the adapter works as expected
+ * Close the jumper
+ * Plug in the adapter again. It should be detected as 'usb asp', not 'amikey'.
+ * Run the firmware upgrade command :
+{{{
+avrdude -c usbasp -p atmega8 -Uflash:w:keyboard.hex
+}}}
+ * Wait for it to finish. It is not too long.
+ * Unplug the adapter
+ * Open the jumper
+ * Close the box
+ * Replugthe adapter.
+
+And you're done!
