PS2 Keyboard on zpuino with computing shield

Recommended Posts

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 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).

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:

/*  SD card test     This example shows how use the utility libraries on which the' SD library is based in order to get info about your SD card. Very useful for testing a card when you're not sure whether its working or not. created  28 Mar 2011 by Limor Fried  modified 9 Apr 2012 by Tom Igoe modified 6/3/2013 by Jack Gassett for the Papilio */ // include the SD library:#include <SD.h>#include "SPI.h"//Uncomment for the SD card on the Papilio DUO Computing Shield#define circuit Computing_Shield#define CSPIN  16#define WISHBONESLOT 12// set up variables using the SD utility library functions:Sd2Card card;SdVolume volume;SdFile root;void setup(){ // Open serial communications and wait for port to open:  Serial.begin(9600);  pinMode(CSPIN,OUTPUT);  Serial.print("\nInitializing SD card...");  // we'll use the initialization code from the utility libraries  // since we're just testing if the card is working!  if (!card.init(SPI_HALF_SPEED, CSPIN, WISHBONESLOT)) {    Serial.println("initialization failed.
