My prop shield arrived.
Testing with teensy 3.1 96mhz opt (clip-jumpers for now), IDE 1.6.7, loader 1.27
I2C scan OK
I2C device found at: 0x1E

SPI serial flash: EraseEverything and RawHardwareTest OK (lastest SerialFlashlib from github), also created and read some files
(reran tests @120mhz, all OK). serial flash OK with teensy LC @48MHz

doing something, but temperature T is funky ?
FIX: added false to endTransmission in readReg(), fixed temperature

added temperature and change readReg to use false in endTransmission, temp 22C ok
sine wave to DAC, AGRND, Vin, Grnd, pin 5 HIGH, DAC and opamp output to cheap scope, all with jumper wires. DAC 3.3v wave looks fine, opamp + output is very jagged (spread spectrum?), but opamp path looks operational
No LEDs, but with pin 5 HIGH, confirmed DATA and CLK are OK with logic analyzer.
