Refresh rate / flicker #17

Closed josephernest closed 9 years ago

josephernest commented 9 years ago

I'm currently filming my hardware project (including a 7seg display) with a camera.

The result is flickering because probably the refresh rate does not fit well with 24fps or 30fps of my camera.

Any idea on how to change refresh rate of Serial7SegmentDisplay?

You'll have to modify the SevSeg library to achieve this. The constant FRAMEPERIOD, defined here is probably the best place to begin experimenting. Try turning it to somewhere between 500-1000.

In fact the problem has been solved by changing the shutter speed of the camera (didn't know it was possible in "Movie" mode). Setting shutter speed to 1/30 or 1/50 worked.
