Hi Guys
I havn't been around in awhile .... seems I only show up when I need help sorry.
I am looking for a preprogrammed USB Keyboard chip. Or a suggestion for a chip that will fill my needs.
I do have access to an eprom programmer but have no programming skills.
Here is what I need the chip to output.
"alt + r "
"alt + s "
"space"
That's it.
It needs to be a USB interface and recognized by windows as a HID compliant device
I built my prototype by hacking an old keyboard, it works great. I need to build some more and need some alternatives.
Here is a picture of the prototype.
The yellow button has one pair of wires and one switch, it is sending the space command.
The green and red buttons are the alt + r" and "alt+ s commands. I filled a little bit off of the r + s switch lobes so the alt command comes first.
All switches are N.O. momentary contacts.
When plugged in it is recognized as a Compaq keyboard and is listed as a HID compatible device.
I have looked at devices like the ipac keyboard emulators but they are pretty pricey.

Any help would be greatly appreciated
