Playstation 2 Controller SPI Interface, Help!
PostPosted: Wed Dec 01, 2004 9:14 pm     Reply with quote
Hello All --

Has anyone successfully interfaced with a Playstation 2 Controller with the built in CCS SPI functionality? I'm having problems establishing communications.. Any comments, sample code, interface schematics would be greatly appreciated.

Thanks,
Gary

Hi friend,
I needed the same project. I was trying to use the spi but it just got me mad. I reproduced the spi behavior moving bits and it worked. Cool

Code:

#include <main.h>

#define lcd_rs         pin_a0      // pino rs do LCD
#define lcd_enable     pin_a1      // pino enable do LCD
#define lcd_d4         pin_a2      // pino de dados d4 do LCD
#define lcd_d5         pin_a3      // pino de dados d5 do LCD
#define lcd_d6         pin_a4      // pino de dados d6 do LCD
#define lcd_d7         pin_a5      // pino de dados d7 do LCD

#include "mod_lcd.c"

#define clk_ps         pin_b7
#define comm_ps        pin_b6
#define data_ps        pin_b5
#define att_ps         pin_b4
#define ack_ps         pin_b3

int play (int ps_out)
{
int ps_in = 0;

   delay_us(2);
   output_low(clk_ps);
   output_bit(comm_ps,bit_test(ps_out,0));  // envia saída
   delay_us(2);
   output_high(clk_ps);
   if(input(data_ps)){bit_set(ps_in,0); } else {bit_clear(ps_in,0); } // lendo entrada

   delay_us(2);
   output_low(clk_ps);
   output_bit(comm_ps,bit_test(ps_out,1));  // envia saída
   delay_us(2);
   output_high(clk_ps);
   if(input(data_ps)){bit_set(ps_in,1); } else {bit_clear(ps_in,1); } // lendo entrada

   delay_us(2);
   output_low(clk_ps);
   output_bit(comm_ps,bit_test(ps_out,2));  // envia saída
   delay_us(2);
   output_high(clk_ps);
   if(input(data_ps)){bit_set(ps_in,2); } else {bit_clear(ps_in,2); } // lendo entrada

   delay_us(2);
   output_low(clk_ps);
   output_bit(comm_ps,bit_test(ps_out,3));  // envia saída
   delay_us(2);
   output_high(clk_ps);
   if(input(data_ps)){bit_set(ps_in,3); } else {bit_clear(ps_in,3); } // lendo entrada

   delay_us(2);
   output_low(clk_ps);
   output_bit(comm_ps,bit_test(ps_out,4));  // envia saída
   delay_us(2);
   output_high(clk_ps);
   if(input(data_ps)){bit_set(ps_in,4); } else {bit_clear(ps_in,4); } // lendo entrada

   delay_us(2);
   output_low(clk_ps);
   output_bit(comm_ps,bit_test(ps_out,5));  // envia saída
   delay_us(2);
   output_high(clk_ps);
   if(input(data_ps)){bit_set(ps_in,5); } else {bit_clear(ps_in,5); } // lendo entrada

   delay_us(2);
   output_low(clk_ps);
   output_bit(comm_ps,bit_test(ps_out,6));  // envia saída
   delay_us(2);
   output_high(clk_ps);
   if(input(data_ps)){bit_set(ps_in,6); } else {bit_clear(ps_in,6); } // lendo entrada

   delay_us(2);
   output_low(clk_ps);
   output_bit(comm_ps,bit_test(ps_out,7));  // envia saída
   delay_us(2);
   output_high(clk_ps);
   if(input(data_ps)){bit_set(ps_in,7); } else {bit_clear(ps_in,7); } // lendo entrada

   delay_us(200);

return ps_in;
}


void main()
{
//!int x=0,y=0,z=0,ang1 = 0,ang2 = 0,ang3 = 0;
int ps_in = 0, ps_out=0x01;
int ps_in2 = 0, ps_out2=0x42;
int ps_in3 = 0, ps_out3=0x00;
int ps_in4 = 0, ps_out4=0x00;
int ps_in5 = 0, ps_out5=0x00;
delay_ms(500);
output_high(clk_ps);
output_high(att_ps);

lcd_ini();

   while(true)
   {
   output_low(att_ps);
   ps_in = play(ps_out);
   ps_in2 = play(ps_out2);   
   ps_in3 = play(ps_out3);
   ps_in4 = play(ps_out4);   
   ps_in5 = play(ps_out5);
   output_high(att_ps);

   lcd_escreve ('\f'); // limpa o display   
   lcd_pos_xy (1, 1); // Posiciona cursor no LCD
   printf (lcd_escreve, "%2X %2X %2X %2X ",ps_out,ps_in,ps_out2,ps_in2);
   lcd_pos_xy (1, 2); // Posiciona cursor no LCD
   printf (lcd_escreve, "%2X%2X %2X%2X %2X%2X",ps_out3,ps_in3,ps_out4,ps_in4,ps_out5,ps_in5);
   delay_ms(100);
   
//!   break;
}

}



The right values to ps_out you can find in here http://store.curiousinventor.com/guides/PS2/#hardware

in this code, the values of ps_in4 and ps_in5 are the data from the buttons.

I hope I have helped.

Cheers!
