Ive manged to get the teensy/madmapper setup working properly but only on a low number of leds. Any setting above 75 leds will make the leds closest to black blink and act weird. Everything else works fine, i can connect and control the whole strip with madmapper, animating correclty. The problem is that the led pixels closest to black act wierd/wrong.
I only want to get this single strip of 250 leds working prpoperly, any suggestions are appreciated.
Led Strip type: WS2812b
Teensy 3.2
-My troubleshooting has been to double check power supply, which i can confirm is working as it should becuase the same setup works fine with other led strip controllers. its a 5v 20A supply.
-Test run the fastled simple test on any number of leds. And i can confirm that this problem does not persist with the simple test file. the leds light up only to the specified number of leds and then cut of cleanly.
-Changed "while (Serial.available() > 0 && bytesRead<30000)" to 3000, 300 and 30. -No change in behaviour.
-Changed both these numbers a few values up and down,-gave no change in behaviour.
"char dataFrame[NUM_LEDS*3];
int readingFrameOnLine=-1;"

Many thanks.
