Emulate keyboard

dr hydra

Does anyone have a spin object that emulates a p/s2 keyboard...I'm looking to use the propeller to read a few buttons and then sent the info to my pc as different keyboard keys...

Mike Green mentioned some code here:

so it should be available.

What I do is have the Prop connected to a Silabs CP2110 USB interface, and have the Prop read buttons and send out packets to the PC.  The PC has an app running that reads the packets and converts to keyboard/mouse commands.  But I think there is a Silabs part that will instantiate as a keyboard, and let you send keycodes direct from the Prop.  I forgot the part number.

A USB keyboard.Basically it is only an ATTiny85, 2 zener diodes and 3 resistors...

Man...I am amazed...this seems harder than I thought...I cannot not get the links to work...the last two solutions appear to require extra hardware and the windows serialkey idea will not work with anything above windowsxp...any other ideas? 
I'm looking to create an arcade machine that gets input from arcade joystick and buttons through a propeller and then emulates the input to the p/s2 keyboard on windows vista

It should not be too hard to write your own keyboard emulator for such a limited number of keys. The only extra hardware you may need would be level converters. Look at some of the objects for receiving keyboard data to get started.
