Activity Stream

Quick update: I am trying an experiment with the SD drives and the notification event we send to host... #if 1 MTP.send_StoreRemovedEvent(storage_index); delay(5); MTP.send_StoreAddedEvent(storage_index);...

That is very cool, ill wait for that instead!

It seems that the while (playWav1.isPlaying()) code works the first time it's called but doesn't work the second (and subsequent) time(s) it's called. In the code section below, it should wait until the outgoing message...

Sparkfun should soon have the version without ethernet.

Interesting, that's news to me that PJRC has started manufacturing both versions. I just checked the SparkFun 16771 stock that I have and it has the ethernet.

As Kurt mentioned the usual way is to use objdump.exe. Here an example using PlatformIO: After compiling, go to the vsCode terminal and cd to your build directory cd .pio/build/whatever_board_you_are_compiling_for....

I wasn't referring to the ethernet jack. More referring to the ethernet PHY. On PJRC.com there are versions with and without ethernet. https://www.pjrc.com/store/teensy41.html

Another question: the Teensy only have 3.3v pin power supply. Majority of encoder are 5v to work. With only 3.3v it is ok ?. What is the solution if it not work properly ? Can I get the 5v from teensy 3.5 vOut to...

If you read the item description, it's the same as the SparkFun Mfg # 16771, which is here: https://www.sparkfun.com/products/16771 Having recently bought a ton of these from SparkFun, it is a Teensy 4.1 without...

I guess you are right on the number. For the rest, that was my idea also.

Hmmm, so the test I just did had this effect: 1. The bootup was normal, phone down and I hear the power up beep from the earpiece as I power up. 2. Lift phone and hear the outgoing message then record tone, I record...

I am sure there are options to give you a list file. Been awhile since I have looked.. The Arduino build gives you a .sym file which tells you where everything is located... I then sometimes will look at... When...

I've been married for over 23 years (3rd time lucky), the wedding Ion Jul 29th is for my youngest son; hope your wedding goes well. I've just retired (Aug 2021) and electronics is a great hobby for retirement. I was...

Yes you can connect to those pins, not sure about any specific header for it. But if you find one that works... I experimented using a few breakout boards and did a quick and dirty castellated extension board to play...

Ah yes. Okay that makes sense I will try it. Thanks a lot. Congrats on the nuptials! My wedding is July 22nd. Fiancee is really starting to tire of the house being an electronics workshop for something I said...

There's a comment under the Youtube video by Surreylic, and one of the answers says... nevermind, had enough time to figure it out myself. But thanks for your hint, saved the wedding today! For anyone with the same...

I just have one question. I use a mixer like this on primesound on live shows and I want to listen only my instrument and voice (input 1 and 2 for example) on my In-Ears (Im the only one using it). How do I select only...

The t4.x's have components on the underside of the boards. You MUST leave a gap for these components or have your PCB routed to allow for these components.

I would recommend Visual Micro with Visual Studio. It gives the stability/understanding of the Arduino system with the IDE of visual studio and Teensy Debugging. I use it all the time and would not go back. I have used...

Hey, I'm also in middle of building this. Did you make any progress? I'm having the same trouble with the bounce, but I actually think it could be the hook switch on the phone not always sending the signal. The...

Thanks for the offer, very much appreciated. I think I have enough to be getting on with just to keep me busy here.

Thanks for your advise, I think you are right, I just need a 24 pulse relative encoder. It s to change the FX Time between multiple FX with MIDI messages (Pioneer Rekordbox) and I don't want fx time change abruptly for...

if a the plastic of the header is too much height, know that after the header is solderd on, you should be able to slide that plastic piece off the header, with use of a little screwdriver or a knife. this way you can...

@craigyb If there is anything i can just ship to you, let me know.

I have installed latest stable Arduino IDE (1.8.19) and Teensyduino (1.56). The problems I have with Arduino IDE is productivity : code edition, selection, completion, navigation... For me, VSCode is really faster. I...

I've tried PlatformIO a couple of times, but ended up going back to Arduino. Arduino has lots of issues, but I do understand how to install it and maintain it. Can you explain where in the PlatformIO process was...

Thanks. After some discussion (https://github.com/ssilverman/QNEthernet/issues/15), it turns out that this is expected TCP behaviour. The solution to reduce the waiting time is to either use keepalive or reduce...

Hello, Thanks for the tutorial, I have dropped Arduino IDE. (Maybe arduino 2.0 would be better) Next step would be to have debugging available, to avoid "println" debug messages :D The PlatformIO single way to...

Would I be able to solder on a surface mount 0.05" header to connect an SPI peripheral or is it reserved somehow for QSPI memory chips?

There are 3 on both t4 and t4.1. But 3rd on sd pins and on T41 on bottom memory chip pins

@KurtE - Saw pretty much what @mjs513 saw.Serial monitor shows removal and insertion of SD card (built in) but the mount stayed mounted in the file explorer. This is using Ubuntu. As for USB it works flawlessly....

Thank you, will check it again.

You say you looked at this? According to FrankB, it works. https://forum.pjrc.com/threads/48430-Program-Teensy-from-another-Teensy?p=289237&viewfull=1#post289237

Thank you for your prompt answer but the problem is that I already have a few units in the field. If I have to upgrade their firmware to include the Flasher code, I might as well use a PC ... This is why I was...

I recommend installing direct from SD rather than via a second T4.1. You need to take what you need from FlasherX and integrate it into your own application. It’s or a plug and play solution.

@KurtE Gave it a quick test run - nothing extensive and mostly with a hub attached more of stress test on the add/remove feature. It does work: 1. Using my M2 drive inserted on boot up it recognizes and I can remove...

Thank you very much for helping and for your time in creating this utility. I am lost though as to how it can be used. Here is what I have: 1) A Teensy 4.1 (T1) running some old firmware which I wish to upgrade....

A few have people have done what you want via "FlasherX" discussed in the thread below. https://forum.pjrc.com/threads/43165-Over-the-Air-firmware-updates-changes-for-flashing-Teensy-3-5-amp-3-6 The latest release...

WELL THAT WAS EASY! Thanks @KurtE, that worked like a charm. Much appreciated!

@kurtE - Nice - will look at the usage and see if it helps MakeFiles - except that one wanted to pick a single 'DISK' for testing.

;) Cool can't wait to see what you come up.

:D Looks like my one should arrive in town tomrrow

I put an order for 2x of the displays.

Info in msg #11 sure looks like all 3 cards are working properly. I have no more guesses left as to the cause of trouble. Only suggestion I have at this point is to add more ways your program shows status, so you'll...

Sorry for the double post, but i have tested with using a pwm signal. Both seem to produce about the same results, although the uno is a lot less stable. The uno shows a result flickering between .30 and and .40, while...
