Update

Introduction

While working on getting the new version of TVout some poor initial design desicions became apparent. The most obvious being the video pin choice; to facilitate higher output resolutions this has changed to the highest pin on a port. There have also been several other changes to make the library easier to use and consume less flash memory.

Hardware Changes

The video pin has changed to pin7 for atmega328 based devices and a7 for the arduino mega/sanguino. For further details see the hardware page of this wiki. If you would like to revert this change comment out the following line in spec/hardware_setup.h:

#define ENABLE_FAST_OUTPUT

Fixing the Function Calls

• start_render(mode) and start_render(mode,x,y) are now begin(mode) and begin(mode,x,y)
  • This change was to keep the system in-line with other arduino libraries.
• select_font() MUST be called prior to using any text as well as including the appropriate font.
  • This change was made to cut down the flash use by only including used fonts.
  • The new fonts included in fontAll.h are:
  • font4x6
  • font6x8
  • font8x8
  • font8x8ext
  • See select_font() for complete use description.
• print_str() is no longer avaliable use print(x,y,string) instead, for terminal like printing use print(string)).
• delay() now takes the delay as ms not frames, use delay_frame() frame delay
• draw_box() has been replaced:
  • draw_rect(x,y,w,h,color)) for an empty rectangle.
  • draw_rect(x,y,w,h,color,fillcolor) for a filled rectangle.
• draw_circle() has been modified the arguments have changed:
  • draw_circle(x,y,radius,color) for a circle with no fill.
  • draw_circle(x,y,radius,color,fillcolor) for a filled circle.
• fs_bitmap() was removed in favor of bitmap(x,y,bmp)

Setup Comparison

Here is an example of the the equivalent setup processes in the beta1.0+ libraries and the older releases:

Pre Beta1.0:

#include <TVout.h>

TVout TV;

void setup()  {
  TV.start_render(_NTSC);
}

Beta1.0:

#include <TVout.h>
#include <fontALLL.h>

TVout TV;

void setup()  {
  TV.begin(_NTSC);
  TV.select_font(font6x8);
}
