@moriczgergo NeoMatrix should not cause any flickering. All it does is translate a cartesian coordinate into a linear coordinate on the strip. Most flicker issues are caused poor power supply; the next issue is the LEDs are sensitive to data line voltage and will require you to purchase a good level shifter.
