*Solved* Fingers Crossed
Originally had 2 issues.
1) White Color Only Flicker - Symptom Intensity Change from Bright to Medium Bright by itself.
2) Grabber Disconnect - Symptom LEDs would go back Background Effect several times a second for short duration.
Solution to problem 1:
Replace Adafruit I2C/SPI IO Level Lifter with Arduino
--Lesson: 'rate' and 'serial rate' are the same. Corresponds to serial baud rate.
Solution to problem 2:
Enable Smoothing
Decrease Update Frequency to 15 Hz
Changed time to 150ms instead of 200ms
--Lesson - O that is what that is for!
Settings I kept:
720x480 at 30 fps for NTSC and PixelDecimation 2
Note:
I switched from Pi 0 to Pi3 because I dont use USB Hub.
A hub is needed to connect grabber and arduino to pi zero
TLDR:
- Problems with flickering?
Try lower the smoothing frequency and lower the framegrabber frequency in your Hyperion configuration.
-Problem with Single Color Flickering
try an Arduino Uno Rev 3 or higher.
