TVout.H problems!!

Projects Programming
1

Hello There . I would really like to get the FFT frequency analyzer project working , or the Arduino PONG sketch working but anything with TV Out is giving me problems like:

'class TVout' has no member named 'begin'

'class TVout' has no member named 'vert_res'

etc...

what should I do?

thanks

(i am trying with arudino version 22)

Well my telepathic senses say that you are not including the header properly, but I'm a lousy psychic, so your code would probably help.

sorry i was reffering to other peoples code and i wasnt sure if i could post that

here goes:

#include <TVout.h>
#include <fix_fft.h>
TVout TV;
char im[128], data[128], lastpass[64];
char x=32, ylim=90;
int i=0,val;
void setup()
{
TV.begin(NTSC,128,54); // Initialize TV output, 128x96.
TV.print_str(2,2," Realtime Arduino"); // TVout lib uses x,y for print
TV.print_str(2,11," Spectrum Analyzer"); // statements. 8x8 default font.
analogReference(DEFAULT); // Use default (5v) aref voltage.
for (int z=0; z<64; z++) {lastpass[z]=80;}; // fill the lastpass[] array with dummy data
};
void loop()
{
for (i=0; i < 128; i++){ // We don't go for clean timing here, it's
val = analogRead(0); // better to get somewhat dirty data fast
data = val/4 -128; // than to get data that's lab-accurate
_ im = 0; // but too slow, for this application.
* };*
* fix_fft(data,im,7,0);*

* for (i=1; i< 64;i++){ // In the current design, 60Hz and noise*
data = sqrt(data * data + im * im*); // in general are a problem. Future designs*
TV.draw_line(i+x,lastpass*,i+x,ylim,0); // and code may fix this, but for now, I*
TV.draw_line(i+x,ylim,i+x,ylim-data*,1); // skip displaying the 0-500hz band completely.
lastpass_=ylim-data; // if you insist, initialize the loop with 0*
* }; // rather than 1.
};*_

Try turning your code into "code" blocks (hit the "#" button with the code selected).

Meanwhile, where did you get TVout.h from? My copy has begin in it, but not print_str. And fix_fft.h?

i got it all from here

http://arduino.cc/forum/index.php/topic,56541.0.html

and then i updated the TVOUT with the newest beta...and i think that was the problem as they specify that the print.string has been removed from the newest version

thanks!
