Call to TV.frame_delay(1); appears to clear the screen

GoogleCodeExporter commented 8 years ago

What steps will reproduce the problem?
1.
      TV.draw_rect   (x+2,y+2,8,14,WHITE,WHITE);
      TV.draw_circle (x+6,y+9,2,BLACK,BLACK);
      TV.draw_rect   (x+6,y+3,1,6,BLACK,BLACK);
2.
     By adding a call to TV.frame_delay(1);
     the screen is cleared and I no longer see rect/circles
3.

What is the expected output? What do you see instead?
  expect:reduction in flicker
  actual:blank screen

What version of the product are you using? On what operating system?
  Beta V1.0

Please provide any additional information below.

Actually I think it may have something to do with my use of the Wire.h 
class...When I get a receiveEvent screen is affected

That would make more sense. This library requires exact timing meaning no other 
interrupts my be used with it. The wire library uses interrupts. I would 
suggest trying the modified i2c library used by the video game shield.

Ensure there are no other interrupts running.
