SPI Interface

Sep 12, 2014 144 Replies

Not quite, but it's pretty rare. But Gigabyte's GA-H81M-DS2 for one lists it and it's a modern socket 1150 board. The parallel port is not a pin header either, the jumbo connector is even in the back panel. I guess some of the old printers from 1990s are pretty long lived... I actually lugged my old Laserjet 4+ to storage a year or two ago. I just don't have a need to print at home any more. The only personal printing need for me is printing paper copies of electronic flight tickets and other travel documents, just in case. But I only travel two or three times a year so not much point having a large printer sitting around for the other 362 days of the year...

The serial port in the form of a pin header is pretty common as is the PS2 in the back panel. Good thing too, I'm kinda hoping to reach 20 years of use of my PS2 keyboard...

Still using my first Cherry keboard with a DIN plug - well over 20 years. :-)

Is this about using the header-pins to drive SPI, which is near compatible to PS2, for kybrd, to free-up one of the USB-ports?

I'm very interested in that. Shall I google for info, or will I be wasting my time?

== TIA.

Having done even bit banged PS2 keyboard interface on other micros PS2 and SPI are totally different.

Yes, look up PS2 keyboard interface plenty around

Good place to start for PS2 are
