PS2 Keyboard on zpuino with computing shield

[Goos_E]

Greetings,

 

I want to say to you Jack Gasset what a great peace of work the Papillio Duo is. But now my question. How do I get the PS2 keyboard to function with my computing shield and the zpuino. I can see that it must work wit SPI, but how do i do that?

Hi Goos,

 

I'll speak to Jack regarding this issue, because I have integrated a PS/2 controller in other designs. It does not use SPI at all.

Hi Alvieboy,

 

I am sorry that was the SD-card, but how do I use a keyboard. I am not a beginner in programming but a beginner in things like keyboards and SD cards. I was busy with Tinybasic and tried to work it with VGA and a Keyboard as input. I am getting stuck on the VGA as well. (but I think I can get out of that).

You could start here https://eewiki.net/pages/viewpage.action?pageId=28278929

Which should explain all you need to know.

Hello Goos,

 

It looks like the examples for the SD library included with DesignLab 1.0.1 are not correct. Alvie and I are working to update the library, in the meantime here is an example sketch you can use:
