I have this exact same issue. I'm waiting on a character reading from Serial to continue.
It works in Serial Monitor by sending the relevant char, but it doesn't work in Serial Plotter. Both are set...
Yep, it works! Glad to not have to worry about the impact on power draw for the ADC inputs.
And this worked with 12V supplied to the VMOT pin, and 3.3V supplied from the teensy for the other power supply.
I wasn't sure whether I should take the 5V from the teensy or the 3.3V from the...
Thanks again. Just thought I'd leave a note on the thread that this worked, in case it helps anyone else.
Is that 150mA a requirement from the 3.3V teensy, or the 12V power supply?
The one with the document I listed is 3809Z-14.
The exact model I have has this info on it:
3809Z-45
0.15A
072007
36mm diameter and 12mm height.
I tried turning them but it didn't feel very different, but this stepper motor is connected to an apparatus where it's awkward to turn the motor and feel how much effort it takes.
I checked and...
This diagram seems like it might be helpful, although I'm not sure how to match up the stepper motor pins.

I have this stepper motor Lin engineering 3809Z-45, which is rather similar to this one:...
Wow, you've put a lot of work into this! I'm interested in building a MIDI control surface for ardour.
Any suggestions on which method to interface with ardour?...
Keeping audio/video/midi streams in sync works really well with JACK which is open source and works in linux/windows/MacOS. This is used to keep multiple software in sync within the same OS, and also...
nevermind. got it. The adafruit seems to be setup by default with the secondary address: 0x77
So changed it here:
iaqSensor.begin(BME680_I2C_ADDR_SECONDARY, Wire);
And it works!
I plugged in the adafruit bme680 board today, and the bsec library sketch is not finding it.
FYI, I also had to add in "while (!Serial)":
while (!Serial)
Serial.begin(115200);
The adafruit...
I can confirm this compiles with the changes. Markus_L811's method worked well above:...
Just wanted to provide an update. I had a 3.6 beta board, but not a 4.x board to test.
So far I've only tried the bmp390 board on a LC, but the boards I ordered work well:...
I ordered some boards of the one I posted earlier. I'll report back if they work on a teensy 4.1.
From your debug, it looks like it's receiving the temperature and pressure calibrations (T1, P1, etc).
I've used the BMP280 and BME280 with the teensy, and am about to find a BMP390 to try.
I'm...
Ran into similar problem again, and thought I'd leave a reference here in case this is helpful for someone searching about how to capture serial data in linux.
This works really well:...
Cool seeing it with the lights on the megaphone, nice touch.
When I did the dalek voice coder, I kinda liked the triangle waveform
sine1.begin(WAVEFORM_TRIANGLE);
Glad you are making progress. How does the audio sound in audacity? After converted?
You can silence or fade the end of the sample in audacity. Pick a zero-crossing to start and end anything you...
Is it running on battery power only? If not, could help.
Could be the microSD card. It's a big power draw and can induce noise in my experience, although I've only worked with writing to microSD...
Not sure if it's your problem, but I'm fairly sure it should be "\" in windows and not "/" for path separator.
If you do it that way I'm not sure if you have to escape the special character
...
That's a great idea!
Ok, just wired up a 2k ohm resistor to 3.3V on SCL and SDA pins. You need a 2k resistor for the SCL pin to 3.3V, and you need another 2k resistor for the SDA pin to 3.3V. Then it came up, and this...
Well, I must've forgotten how I wired it. It definitely doesn't work as-is. For testing, look under i2c_t3 menu for the "basic_scanner" sketch. It checks all i2c addresses for an acknowledgement.
...
Did you setup i2c_t3 with the I2C_PULLUP_EXT in the begin function?
I'll try and post a simple sketch later. I might have done more of my testing on 3.2, but I'll try it on LC.
I doubt there is...
I've likely used that same MPU6050 breakout board. I got 10 of them off of ebay once....
That's awesome! Nicely done. That looks really nice from an 8x8 grid.
I wonder if there is a clever way to create a heat map of an area by repeatedly panning over a certain area. Basically, use...
I thought some people on here might be interested to know that TechShop closed their doors this last wednesday.
Disappointing. :(
...
I think that basic functionality as described would be very valuable.
In the long run, I think it would be worthwhile to have it use the same method as the audio library. Would it make sense to...
What I'd like to see is extending the Audio Library to fill queues with other ADC pins.
This doesn't quite make sense to pass a bunch of pins with a constructor but you get the idea.
This would...
In audacity, you have to import as raw audio. You can then export it as wav file.
On the post about neutronned's mic, you'll find more code.
Not sure about the bins, but your results might improve if you can standardize the hammer hit with an apparatus.
Also something like a boundary microphone might be helpful:...
This really seems like it's much easier now. With the new teensyduino, I'll have to give this a go. Especially since I switched to the new version of sublime and it's really sluggish on linux.
In case it wasn't clear, that last link I gave was to an automatic timer for an electrical outlet. I plug the charger into that and set it to turn off the electrical outlet after 1,2,4,or 8 hours....
Wow, adafruit has been busy. I see they have mynewtOS on the nrf52 feather. Any experience with that?
I think if you could be less than $50 that would be good.
Same size as AA.
BTW, you can use dummy versions (or just add wire in unused AA slots that are wired in series) to use these to replace AA batteries, and get much greater battery life.
In other...
Yeah, I think the pricing is in your favor as this is clearly not a teensy replacement. It's a specialized version. Are you buying the bootloaders from Paul? If you are, likelier to be OK.
I also...
I use the 14500 batteries. These are 2000mAh:
https://www.amazon.com/gp/product/B00PIDNTRA/
I also have them in 1000mAh, but can't find the link right now.
Just to be clear, this is essentially a teensy with an ntf52 on board that communicates with the teensy over serial? I'm assuming that's why there's 2 micro-USB connectors (one for teensy portion,...
I think you can power it from the 3.3V pin on the teensy. If that doesn't work, you could use the 5V, but I would wait until someone else chimes in as I'm not positive.
Also, I think the "INT" or...
Ahhh, I was thinking he already had an input, but I guess it was just outputting a sine wave so it wasn't. Thanks.
Yeah, I did, didn't see anything about AudioOutputI2S.
I think he was wondering about why you need to declare this: AudioOutputI2S out1
I've been confused by this as well. I'm not sure he does need that declaration.
Do the sensors stop working completely, or just the humidity sensing? Does temperature and pressure sensing continue to work? Am interested in what you eventually find is the problem.
I haven't...
I'm using an electret mic, but the gain is fine w/headphones or line out.
It was just the output over USB. I'm not sure why cause I had it working in another sketch at nice levels.
I'll try and...
I tried recording it to USB but the gain was really low. Not sure why.
I mainly came here to say that I found this site:
http://webaudio.prototyping.bbc.co.uk/ring-modulator/
I was just thinking about a Dalek simulation. I'm gonna have to try this out. Thanks for posting, I was thinking not enough time before halloween to try something.

Could you post a pic of what it looks like when it appears to be working?
The amplitude seems too small to expect that you would capture anything physiologic or even external noise: ~0.1uV

I think I remember that you can't even turn them by hand, cause of the gears probably.
