seems like a nice product 🙂

any idea how to use this with an arduino?

couldn’t find a library…

i also never saw this before

[needle]

thanx! now i can mount my potentiometer to the chassis… 🙂

(i removed the small one because it was in the way of the rj45 connector)

[needle]

I’ve got another question about the potentiometer;

the middle pin is connected to analog 2, but where do the outer pins go to?

Alright, couldn’t sleep… so just got out of bed again, thinking about the “while”

it didn’t work, but the following does 🙂 :

#include 

#include 



TVout tv;

int i=0;

unsigned char x,y;





char message[280] = "";

char s[32];

unsigned int n = 0;

int index = 0;

int messageLen = 32;

char saveChar;

//net

#include 

#include 



byte mac[] = {  0x90, 0xA2, 0xDA, 0x00, 0x4F, 0xAF };

byte ip[] = { 192,168,1,121 };

byte server[] = { 195, 211, 72, 36 };



// Initialize

Client client(server, 80);



void setup() {

//tv

tv.begin(PAL,120,96);

initOverlay();

tv.select_font(font6x8);



//net

Ethernet.begin(mac, ip);

tv.print(0, 0, "connecting...");



// if you get a connection, report back via serial:

if (client.connect()) {

tv.print(0, 10, "connected");

// Make a HTTP request:

client.println("GET /~deb5250/other/arduino/twit.php");

//client.println();



}

else {

tv.print(0, 10, "connection failed");

}



}



void loop()

{

if (client.available()) {

tv.print(0, 20, "filling array");

for(int j=0;j<=139;j++) {

char c = client.read();

message[j]=c;



}

}





saveChar = message[index+22];

message[index+22] = '';



for(int x=6;x>=0;x--) {

if (x<6) {

tv.delay_frame(1);

}

tv.print(x, 67, message+index);

tv.print(0, 75, "        ");







}

message[index+22] = saveChar;

index++;

if (index > 139) {

index = 0;



}









}











void initOverlay() {

TCCR1A = 0;

TCCR1B = _BV(CS10);

TIMSK1 |= _BV(ICIE1);

EIMSK = _BV(INT0);

EICRA = _BV(ISC11);

}



ISR(INT0_vect) {

display.scanLine = 0;

}

now i have to change it to refresh after a X period of time….

[needle]

Ah right! that’s a good suggestion, i’ll try that asap when i get of work tomorrow 🙂 i’ll keep you posted.

[needle]

there is no problem getting the tweets from the web and into the arduino, i’ve written a small piece of PHP, that get’s the latest #-tag i specify.

and put’s that into a single line, so i don’t have to do anything to change it inside the arduino program,

http://195.211.72.36/~deb5250/other/arduino/twit.php

i guess the problem is when adding characters to the message array.

if i add it at the beginning like this:

char message[] = "...this line is exactly a 140 character's long. like a tweet has a max. of a 140 character's. i'm almost there and only 25 chars to go.ABCDE...this line is exactly a 140 character's long. like a tweet has a max. of a 140 character's. i'm almost there and only 25 chars to go.ABCDE";

and leave out this:

message=c;

so if i don’t add anything to the array but just give it a pre defined array it works very nicely…
