Hello,
I have a trackpad here wired up as show on the arduino site.
And i have uploaded the code for the PS2 and that works perfect.
Now i want to take this a step further and i want the movement to change the brightness of to LEDS, 2 for X and one for Y.
I used this code and that works but not so great:
#include <ps2.h>
/*
* an arduino sketch to interface with a ps/2 mouse.
* Also uses serial protocol to talk back to the host
* and report what it finds.
*/
/*
* Pin 5 is the mouse data pin, pin 6 is the clock pin
* Feel free to use whatever pins are convenient.
*/
PS2 mouse(6, 5);
/*
* initialize the mouse. Reset it, and place it into remote
* mode, so we can get the encoder data on demand.
*/
void mouse_init()
{
mouse.write(0xff); // reset
mouse.read(); // ack byte
mouse.read(); // blank */
mouse.read(); // blank */
mouse.write(0xf0); // remote mode
mouse.read(); // ack
delayMicroseconds(100);
}
int ledPinX = 9;
int ledPinY = 10;
void setup()
{
Serial.begin(9600);
pinMode(ledPinX, OUTPUT);
pinMode(ledPinY, OUTPUT);
mouse_init();
}
/*
* get a reading from the mouse and report it back to the
* host via the serial line.
*/
void loop()
{
char mstat;
char mx;
char my;
/* get a reading from the mouse */
mouse.write(0xeb); // give me data!
mouse.read(); // ignore ack
mstat = mouse.read();
mx = mouse.read();
my = mouse.read();
analogWrite(ledPinX, mx);
analogWrite(ledPinY, my);
/* send the data back up */
Serial.print(mstat, BIN);
Serial.print("\tX=");
Serial.print(mx, DEC);
Serial.print("\tY=");
Serial.print(my, DEC);
Serial.println();
//delay(2000); /* twiddle */
}
Does anybody now how to do this write?
best regards
Ronald
