• how about using existing 16 timer? is everything on same clock now?
• tried LUT for jitter, no effect.
• Tried blocking interrupts, no go
• tried tuning frequency to just over 100HZ, no good.
• Is it the clock?

its not the LEDs; oothers do it. Its not the different timers because I've elimitated the systick and timer functions Voltage or current related? not power supply; tried lipo w/ higher voltage.

• sudo easy_install -U pyserial
• python miniterm.py --port /dev/tty.usbserial-A4016VJT -b 31250 -DDD

-DDD shows raw hex
