Anyone ever successfully get teensy3.1 working over for receiving values above DMX address 62? I’m using the DmxReceiver code (GitHub - jimparis/DmxReceiver: DMX Receiver Arduino driver for Teensy 3.1 boards) which is adapted from wards original dmx code (Arduinoesque overriding of core functionality | Teensy Forum). Thing is… it works great receiving values up to and including 62, then all values above are a garbled jitter mess. It feels like it may be a buffer size issue tucked somewhere in the guts of the teensy core, but I haven’t been able to figure it out.
I haven’t done DMA receiving on the teensy3.1 - but there’s also the teensy forums at http://forum.pjrc.com
Wrong forum, fair enough… it’s ultimately for the flower of life 
I figured it was for something along those lines I just know that the teensy forum is likely to have folks who’ve worked on those libraries around/answering.
It’s weird that it’s having problems specifically with the high bits. One curiosity/thing to check/test - when the values are garbled, is the whole value garbled, or is it only the high two bits that become random?
Have you tried editing serial1.c to increase the Serial1 buffer size?
Thank you Paul! Problem solved… it’s funny, I swear I looked in serial1.c to find a buffer size variable but didn’t see it. Many thanks
