shift(direction,distance)

Will move the data on the screen in any direction by any number of pixels

Hello,

I was try to compile the demo program for PAL in Example folder and i get the 
bellow error:

C:\arduino-0018\arduino-0018\libraries\TVout\TVout.cpp: In member function 
'void TVout::render_setup(uint8_t)':

The version i was try it was the TVout_R5.9

Can you please help me to fix this problem, I use ATMega 168.

Thank you in Advance.

Best Regards,
Tasos

I'd like TVout to have the ability to call a hook during the vertical blanking 
interval.  I am using this capability to communicate with an I2C device.

Example implementation

TVout.h:
// declaration of set_vbi_hook function
void set_vbi_hook(void (*func)());

TVout.cpp:
// implementation of set_vbi_hook
void TVout::set_vbi_hook(void (*func)()) {
  vbi_hook = func;
}

video_gen.h:
// extern declaration of vbi_hook function pointer
extern void (*vbi_hook)();

video_gen.cpp:
// declaration of vbi_hook function pointer and invocation of function at 
beginning of VBI
void (*vbi_hook)();

// in active_line()...
    if ((display.scanLine + 1) == display.stop_render) {
        line_handler = &blank_line;
        if (vbi_hook != 0) {
          vbi_hook();
        }
    }


Let me know if you have any questions; this should be pretty self explanatory 
for you.

Hi,

I'm trying to compile the latest hg source but I have these errors :

$ /usr/bin/avr-g++ -c -mmcu=atmega328p -I. -DF_CPU=16000000

I fixed that using "else" instead of "elif".

Currently the Vertical Sync works by simply extending the time that the sync 
line is held low.  This does not follow the NTSC or PAL spec; fixing this will 
result in higher compatibility with more devices.

rtttl(song)
play a RingTone Text Transfer Language stored as a string in program memory.
A stop function will also be included.

Create 2 functions one for filled one for not filled. Rounded corners will be 
dropped unless this is a major problem.

Hello,
it can be cool if we have some simple way to swithc between PAL and NTSC.
There should by some #defines which will enable us to compile tvout with PAL or 
NTSC or both and then we will able to select one of those modes (if there are 
compiled-in) at runtime.

millis() looses all accuracy when used with this library, so create a 
replacement.

when i put this into the code it dosent turn orange and says theres an error 
also with draw_circle too plz fix fast

What is the expected output? What do you see instead?
Error

What version of the product are you using? On what operating system?

R5.91  on ubuntu 10.04
Please provide any additional information below.

bitmap(unsigned char x, unsigned char y, const char bitmap)

Place the upper left corner of a bitmap at point x,y

the bitmap should be encoded as follows:
{#ofBytesWide,#lastByteDrop#ofLines,imageData.....}
msb of a byte is the left most pixel in the byte.
the following byte being the next 8 pixels
lastByteDrop contains the number of pixels to be removed from the end of the 
last byte on each line.

What steps will reproduce the problem?
1. Use of the method/call .draw_box. 

What is the expected output? What do you see instead?

- In the comments for the .draw_box method in TVout.cpp, the comments
says as follows:

"draw a box x1,y1 to x2,y2".

One would assume this means a box with top left corner in x1, y1 and a bottom 
right corner in x2, y2. This is how ever not enterily the case, 
as the parameters are x1, y1 (upper left corner) and x2 and y2 being
the width and the height of the box. After some debugging i found that I
interpreted the comment/method wrong.


What version of the product are you using? On what operating system?
- R5.91

Please provide any additional information below.
- Just wanted to inform you, so others don't get stuck with this method.
Otherwise... thanx alot for a solid and super library.

Speed up the drawing algorithm specifically drawing filled circles.
Modify syntax to drop safety check, create separate filled/non filled functions 
by the same name.

Printing chars with codes > 127 crashes program.
It can be easily fixed by using unsigned char instead of signed:

virtual void print_char(uint8_t, uint8_t, unsigned char) = 0;

Also, after fix, you can use full ASCII character set at file ascii8x8.h
(sample files is attached)

provide a interface to force the use of certain parameters. Such as vertical 
scaling, output start line, output offset time, output method.

What steps will reproduce the problem?
1. If pin 1 of the video port is HIGH, then horizontal sync is messed up


What version of the product are you using? On what operating system?
Trunk with video pin on Arduino pin 7.  ATmega328


Please provide any additional information below.

Myles,
(nootropic here).  Since the video moved to port 7, there is a bug in the asm 
routines render_line5c and render_line6c.  These lines near the end need to be 
changed from:

                "svprt  %[port]\n\t"
                "bst    r16,1\n\t"
                "o1bs   %[port]\n\t"

to:

                "svprt  %[port]\n\t"
                "bst    r16,7\n\t"
                "o1bs   %[port]\n\t"

That is, the seventh bit of r16 needs to be written out to the port, not the 
1st bit.  The problem only becomes evident if pin 1 of the port is set.  The 
hsync gets messed up.  I found this while trying to use Arduino pin 1 as a 
digital input with the pull-up resistor set.
