The forum rule requests that you provide a working sketch (use CODE tags #) that demonstrates the problem. How have you wired up the ENC28J60 to the T3.6? Which version of IDE are you using, and do you have a link...
The prop shield uses pin 7 to enable the LED AND buffers, and pin 11 to drive the LED string. You didn't provide a runnable sketch as the forum rule requests. Have you tried the small LED example on...
the adafruit MCP23017 library uses Wire.h, that will conflict with your sketch using i2c_t3.h. The T3.6 is not 5v tolerant make sure you power the MCP23017 with 3v3. You also will need pullup resistsors (to 3.3v) on...
if i comment out the PRIMASK asm code, the jitter/glitch seems to go away on pin 12.
// asm volatile (
// "MOVS r0, #0 \n\t"
// "MSR PRIMASK, r0"
// );
EDIT: well, on re-running test, i still...
yield() is a weak reference that is called each time through loop(), hardware/teensy/avr/cores/teensy3/yield.cpp
yield() checks on serial events and such.
You could try overriding it, but your timed/scoped event...
I can't explain your max force observation. And to correct the semantics, when you double the range to 8g, the sensitivity is halved to 0.976 mg/LSB (Table 61, page 56)..
FWIW, shaking my prop shield in 8g mode,...
Try
if (!write_reg(i2c_addr, FXOS8700_XYZ_DATA_CFG, 0x02)) return false; // 8 G
and double the value in G_PER_COUNT in NXPMotionSense.h, so your earlier 2.51 measurement becomes 5.02
It's possible you'd need...
From page 56, fs are the low-order 2 bits of XYZ_DATA_CFG register (address 0x0E) , or in the library, FXOS8700_XYZ_DATA_CFG. But changing from 4G to 8G will probably mess up other parts of the NXP library that assume...
in the NXP library, NXPMotionSense::FXOS8700_begin() has
if (!write_reg(i2c_addr, FXOS8700_XYZ_DATA_CFG, 0x01)) return false; // 4G range
you need to check the data sheet, but i think setting it to 0x02 would get...
I am guessing that you are referring to this sketch

It appears the intPin is not really used in the sketch...
"... a separate 5v supply with common ground to T3.2."
"I decided to solder on pins to pinouts 20-23" -- i can't quite tell from the photo, but the T3.2 gnd pin needs to be soldered too. For breadboard work, you...
Can you attach a photo of how your T3.2 is wired to your servo? Servos can consume more power than the USB 5v from T3.2 can provide, so you might need a separate 5v supply with common ground to T3.2. ...
I ran your server sketch on a T3.2 (IDE 1.8.5 1.40) with my local IP and mac address. Server seems to be working. I accessed from browser with http://192.168.1.15/reset and http://192.168.1.15/trigger and got back...
i had edited my post #2, -- have you tried an array like
unsigned const int * samples = {AudioSampleSnare, AudioSampleHihat};
you have to copy the sample files (.cpp and .h) into your sketch folder
try looking at and running the SamplePlayer example https://github.com/PaulStoffregen/Audio/tree/master/examples/SamplePlayer
The sample names are unsigned int array names, not character strings or file names. So...
Not that one would want the overhead of FatFs on a SPI flash, but just for the record, I did get an Adafruit SdFat SPI flash library to work on T3.2 with prop shield SPI flash. Brief discussion here:...
Just for the record, here is another Winbond SPI Serial flash that works with teensy SerialFlash lib. SPI flash is 2MB W25Q16BV. example RawHardwareTest reports:

Re: output is inverted
you might configure for falling, PulsePositionInput myInput(FALLING);
that's what I used with a Spektrum trainer cable, and you need a common ground between PPM cable and T3.5
you may need to study the T3.5 ref manual. I think you can use the PDB timer to continuously clock the DMA transfers from the GPIO, and use DMA interrupts of half-done and done to ping-pong the DMA buffers. There are...
On linux sox tmp.wav --bits 16 --rate 44100 --channels 1 TOPGUN.RAW

you cannot use ADC with AudioInputAnalog, see the teensy audio gui side bar for AudioInputAnalog, it states "analogRead() must not be used, because AudioInputAnalog is regularly accessing the ADC hardware"

Does the blink example work if you compile and run it ?
To your sketch, in the loop() before the delay(1000); add
Serial.println("hello");
to confirm that sketch is running. It's likely you have mis-wired...
the teensy audio lib also uses PDB to clock ADC_0 and ADC_1 with DMA (44khz, sample size 128)
https://github.com/PaulStoffregen/Audio/blob/master/input_adcs.cpp
Assuming you are using https://github.com/esp8266/Basic/tree/master/libraries/Micro_OLED_Breakout
here is a possible fix for begin() in SFE_MicroOLED.cpp: add interface check, resulting in
if (interface != MODE_I2C) {...
Hmmmm, i may be reading the SFE_MicroOLED library wrong, but it looks like dcPin may not be set and defaults to 0, which would interfere with your pin 0 usage (RX1)
The T3.2 DAC is 12-bits, and with proper wiring/environment you might get 13 accurate bits from the ADC. There are examples on the forum of using DMA (ping-pong buffer mgt with DMA done/half-done interrupt) and PDB...
Sanity check. If you are testing SPI flash on teensy audio adaptor, note that you must modify the SPI pin settings. See comments in examples, e.g. RawHardwareTest.cpp
//uncomment these if using Teensy audio...
Most of the Adafruit and Sparkfun libraries use the Wire library internally, so you cannot easily change to using Wire2 without editing the library files. For example, this LiquidCrystal library...
It will be hard if the T3.2 DAC pin (A14) is soldered to shield AudioIn. If you can isolate the DAC pin, you could look at it with a scope or attach it to a breakout amp+speaker (e.g....
Re: AudioInputPDM
FWIW, I did simple AudioAnalyzePeak tests with T3.2, serial plotter, and Adafruit PDM mic
https://www.adafruit.com/product/3492
3v3 GND, CLK to pin 9, OUT to 13, SEL NC
works for me
Update: I don't have the breakout, but since the I2C logic on the breakout is controlled by an ATmega168PA, I downloaded the firmware onto a UNO and added the library to IDE...
Try the teensy builtin ADC stuff, in loop() do Serial.println(analogRead(A5));
or with the ADC lib try adc->analogRead(A5)
review https://github.com/pedvide/ADC/tree/master/examples
Just guessing ... but to see if you can get Firmware version right on Teensy, try editing the library. In get_addr_dta() change Wire.endTransmission(); to Wire.endTransmission(false);
There are some int's in the...
I just tried 1.8.5 with Teensyduino 1.42 Beta #5 on 64-bit linux Ubuntu 16.04.4 LTS and ran simple sketch with println and delay in loop(). it seemed to print every other line and then froze after 7 or 8 lines. ...
Try powering LM35 with 3.3v and get rid of INTERNAL ref and use 3.3 in calculation, and this sketch works for me
float tempC;
int pinLM35 = 15; // i have been using pin 15 for measurements

Won't hurt, but Teensy attachInterrupt() was extended a few releases back to internally set pinMode to INPUT

Can you test the SPI pins by running some of the SPI Serial examples on the propshield flash (pin 6 LOW to access SPI flash)

If sketch was working before, I suspect loose wiring. Perhaps attach a photo of your wiring. Is the T3.6 LED lighted?
The Teensy I2S pins connect with the codec on the audio board, and the codec is actually driving...
Teensyduino comes with ST7735_t3.h
try the examples from that library

Are you watching serial output on Teensy monitor and are sure you are not getting any garbage from serial port? strcpy() and untested strtok() make me nervous. :D
if i send a string of...
Hmmm, I didn't test, but your WDOG config looks suspicious.
1) WDOG_PRESC needs to set the lower 3 bits of the upper byte of the register, so your 30 is meaningless, prescale is 0 (no prescale)
2) you have...
