Yeah, you'r right – I just needed someone smarter than me to confirm. Following the link, RAM1 was labeled 512K (not b or B), so the extra confirmation was helpful. Knowing more about all the...

Thanks, that helps a ton!

The one thing I haven't been able to find out: is "313024" is bytes or bits? Aka – how many KB is 313024?

How exactly does one read the memory usuage compile data for Teensy?


Memory Usage on Teensy MicroMod:
FLASH: code:164080, data:33808, headers:8956 free for files:16308228
RAM1:...

As an additional note, the 20 that I recently were replacing 20 of a larger order that demonstrated defective pins.

Unfortunately, it's still an issue. Again – Sparkfun has made huge strides and demonstrated phenomenal customer service through it all, but it still remains an issue.

I just received a fresh batch...

Yeah, I have to admit I do agree with this statement.

The form factor of MM is so much more appealing for repeated projects/products. However, the amount of required testing and inevitable issues...

Thanks, Paul. That makes a ton of sense. It seems that was the case here.







This looks incredible and would definitely solve my sd audio issues with cards that are a bit shy the...

Just to reiterate some of the things that others have already said:
• Initially 50% of my MicroMod units were defective (upon arrival or at a later time).
• Since additional QC measures have been...

For audio projects, I typically use the classic SanDisk Ultra (A1; 64 GB; U1; XC)

But after noticing the Amazon Basics (A2; 64 GB; U3; XC) performed better with the Blackmagic Speed Test, I...

Thanks a ton for the great idea. I'm new enough to this that I never even thought about that!

Would you mind looking over my circuit below and letting me know whether it's correct? I used this...

Wow. I'm very glad I came across this. I've been going crazy trying to recode, design, and re-order prototype PCBs. There was just always something that wasn't working properly. This explains it.

PROJECT DESCRIPTION
So I have a project with a Teensy MicroMod. I want to incorporate MIDI IN and EXPRESSION via a single 3.5mm TRS jack. There is a 3PDT switch that changes the 3.5mm TRS jack...

Thanks a ton for the quick reply and confirmation. That makes a lot of sense.



I actually am planning on using 1/8" TRS plugs/sockets. Any idea what should be added where to the circuit to...

Just a quick (and probably dumb) question: Is the circuit from this webpage suitable for Teensy MicroMod?

Also, would anything need to be added for static protection?

Thanks!

Incredible. Can't wait to mess with it! Great work!

Very interested. Looks super cool!

Okay, I ended up getting it to work with MM for anyone else trying. I pretty much just deleted the "#if defined(ARDUINO_TEENSY41)" in order to force it to execute the next line. I really only use...

Anyone have any ideas how to get this to work with MicroMod?

I've tried switching this:

Thanks! I couldn't quite figure out if that was possible or not with the Flasher4 library. Would you happen to have a quick summary on how to do that via the SD card? I've been messing with the...

Awesome – this is a great starting point for me!
Thanks for pointing me in the right direction!

Is it possible to use playSdWav() to play a wav file by only using the first part of the file name?

I have noticed an issue where using a microSD over SPI is now at reduced speed and performance in Teensyduino 1.54 Beta 5.

While using Teensy 4.0 with Audio Shield Adapter with 1.54 Beta 5, I...

You're right... there definitely are reduced speeds for the microSD via SPI in these updated versions with Teensyduino 1.54 beta 5.

I have a sketch that essentially crossfades two WAV files by...

Would anyone have any ideas as to why I am getting really slow read write speeds with a Teensy 4.0?

Wow – huge thank you!!
I've been working toward this for a long time with no success. Truly appreciate you figuring it out and taking the time to share it!

Is it possible to adapt it for Teensy...

I am trying to accomplish the same thing. It's been driving me crazy.

Adafruit's TinyUSB Arduino library is about as close as I've seen to this becoming a possibility.

Here's a demo of it in...

Awesome! Thanks for taking the time to share that – very helpful!

That's very clever and much simpler than my workaround. Would you have the time to show an example like a screenshot or the 'export' from the GUI tool?

Thanks for the continued responses!

The Polaron DIY Drum Machine is pretty sweet! And the OpenAudio Library is awesome– great work on that!

I was using a 4.0.

I would greatly appreciate some help on this 🙏

I'm working on an audio project that I need to use PJRC'S AUDIO LIBRARY and ADAFRUIT'S TINYUSB LIBRARY.

I am also interested in WebUSB and would be glad to help test.


It seems as though Adafruit's TinyUSB library already has WebUSB built in to it (see the examples):...

I thought that was the case. Thanks for looking at it. I've been messing with it a fair amount, but it's a bit out of my expertise to make it happen.

Does that mean that theoretically Adafruit’s TinyUSB library should already be able to compile on a Teensy 4.0 through Teensyduino? Or what would need to happen to make that work?

Admittedly, I'm pretty new to this stuff.

BSPs is something I don't know too much about. Would it be pretty complex and difficult to port it myself? (or do whatever needs to be done to get...

I filed an issue on Adafruit's TinyUSB library repo (https://github.com/adafruit/Adafruit_TinyUSB_Arduino/issues/63)

I pretty quickly received a response from Thatch:



Would anyone know how...

You're awesome thanks! Also I've been checking out CircuitPython – really cool stuff. Thanks for your work on that and bringing info to the forum.

Thanks for the help so far!

Adafruit's TinyUSB Library is an awesome Library, and the Teensy is an awesome board. Would love it if I or someone could find a way to bring those worlds together.

Hello,

Adafruit has a library which allows your computer to read an arduino like a mass storage device and realtime interact with it. This has been something I've been trying to accomplish for...

Hey thanks for also jumping in to help! It's not that I am "unwilling to show code." My question was just more general and hypothetical rather than relating to any specific code I have, but I...

Thanks for the response Pete!

To answer your question and give more information – My WAV file is like 10+min. When I trigger a release (before the end of the file), I just want it to slowly fade...

Hello,

My problem is that when I give WAV files a slow release time (about 4000-7000ms), it sounds like it abruptly stops at the end instead of a more natural expected fade sound. (ie. Continue to...

Yes! Using the envelope object is a genius idea! In my application, the tracks will always fade in and fade out – so that's perfect.
I figured that was the case regarding needing multiple playSdWav...
