OK, to understand this better, when you say full chip erase does this mean the bootloader will also be removed or just the sketch?

Was wondering if i could join AGND and GND.

That's what I did and it works OK now.

Good day guys and gals,

I'm using the teensy in an automotive environment. The sound recorded through the teensy is fine until i connect the teensy to the ground of the car.
AGND is used on the...

OK yes I realize that now.

I'm unable to flash the device as a sound driver, therefore the audio tool doesn't work to that end. Maybe works as you have it, maybe as an independent audio device.

The bare minimum that presents the problem. I've added a line Serial.print("Works up to here"); to let me know when the program freezes. Moving line below the analogRead will show that it froze at...

Does not work for Teensy 4

Is there some limitation with using the audio tool and analogRead (different pins)?

My code freezes whenever it reaches that line that has AnalogRead.

when I remove the audio design objects...

OK would really really really love that.

Hello,

wanted to move my project over from 3.2 to 4.0. It's an audio project (serial + audio)

When trying to compile I only see serial option for teensy 4. Will this change soon or does the...

10 bits might would be fine for what I'm after. But still interested in knowing how to do the pre-DAC outpuits :-)

I guess I'll just use the Pt8

I have no problem using a self configured DAC, but i still don't know how to wire it up in the gui to a set of pins that would allow for this.

I just want to be able to get a small analog signal out after using the audio library. Can you verify that pins mentioned above will work? I'm planning for the device, I don't have it yet

I noticed my 4.0 doesn't have the DAC pin that the 3.2 had. Is it possible to use one of the other pins to do this?
What do you guys recommend?

Simulating this in multisim looks promising. What am i missing here?

OK. I saw that circuit, and I'm still thinking of an easier way,

So backfeeding is a concern, OK i hear that.
Will it still be a problem if i put a diode after my regulator to drop the voltage to...

THanks. Wonder where this is on the 3.6.
Tomorrow I search or if anything i come back here.

And is there a diode between the USB and the VIN?

Hello,

So I've been reading some things on here and I don't quite understand some of it.
Is it possible to have my teensy powered from a regulated 5V source (VIN), and then I plug on a usb cable...

OK will check it out later. I originally designed around an arduino nano and used an external watchdog on the reset pin, but since that is harder to access on the teensy, well, here I am

I'm on a 3.2

I found this online by paul https://github.com/PaulStoffregen/Arduino-1.6.1-Teensyduino/blob/master/hardware/arduino/sam/system/libsam/source/wdt.c was curious about that

So seeing that the arduinos use a different mcu than teensy, would the watchdog work the same way?

if not, did the teensy library supplied got updated with its own modification to the arduino wdt...

OK So i'm looking in the designer and I see they point to some example in the arduino that I cannot find. I see other teensy examples but not the audio examples. Is there somwhere to download them?
...

OK. a digital mic is not an option as i'm applying it to an existing hardware.

I want to see the amplitude of the sound after the frequency is filtered.

I found this link. Will explore and come back if something isn't clear. I'm not looking for spoonfeeding, just directions thanks again

Hey frank, thanks for replying.

Expense is not as much of an issue as real estate.

I tried following the video and it seems to have a set path outside of which I'd like to go - the audio...

Good day everyone,

MY first post here.

So i've been looking to use teensy as an audio filter but what I've seen so far from my search shows an audioshield involved in the process. I'm still...
