Confessions are good for the soul! Sorry for your loss :( I don't use the IDE setting (or rather, have it set to 600), just what I set in code. I poll the tempmon each second and have a graph overlay available that stays on top of my UI showing...

FWIW - I have been running my Teensy 4.1at 816Mhz for 4-5 years now, for long periods at a time each use. All my Teensys subjected to this are still operational. I have a small (10mm x 10mm x 4mm) cheap, copper heatsink sitting on the processor...

Hi, (no idea, what the Baby has to do with all of this....) Thanks for sharing the benchmark! In my opinion, the numbers without overclocking are most interesting. On the Github, we can find them though and this is given as 600 for Dualcore Pico2...

Why not set up the new array before deleting the old one, so the critical moment boils down to simply assigning a new pointer to this->waveshape.

Enough. You need to put that back in the deck and consider said people reading this when they are old enough.

U3 5V regulator pinout is not correct. Pins 2 an 3 are swapped.

Totally agree, K7805-500R3-LB is a DC-DC switcher and a linear regulator would be a better option. From the various manufacturers I looked at for K7805-500R3-LB, they follow the linear 7805 pinout. Maybe @young.javier is using a part from a...

This is exactly the sort of thing I was talking about when I mentioned "acting like a victim" earlier. When this thread began I had no idea who you were, nor Limor. Adafruit to me is just a business like any other, I don't care to know who runs...

@ptorrone: I'll try to be very clear, and concise (I continually write/talk too much !!). 100% of your rant, from the very first OP to this most recent post, and everything in between, most certainly & much more properly, belongs on the...

I've stayed mostly quiet on this matter so far, but I want to make one thing clear. Adafruit can buy Teensy, just not directly from SparkFun. SparkFun has not decided Adafruit is cut off from buying Teensy. In fact, when Robin and I met with...

I'll repeat those pink bags don't shield from ESD, they just don't generate much static when handled (compared to raw polythene etc). The silver/grey bags are Faraday cages, but non-shorting (the ultra-thin aluminium layer is sandwiched), so...

Quite frankly I find it strange that supplier like Sparkfun does not want to sell their products to anyone who wants to buy. It is business. Just leave your egos at the door and get back to business. I guess that the whole drama wouldn't happen...

I don't think anyone is against you making teensy accessories. It's just that we don't understand your freensy board. It seems to be stepping on Paul's toes and it doesn't seem necessary at all. On that one particular account, I think we're...

Given OP's previous behaviour, closing the thread (for any reason other than their own request) would give them another excuse to act like a victim.

The confusion might come from the fact that it might not be classic 7805 linear regulator, this part on the schematic has symbol of K7805-500R3LB. When I searched for it it looks like switching regulator that is "replacement" for 7805, but might...

I agree this probably isn't productive for anyone, but for now I'm going to allow this thread to continue. However, I'm absolutely drawing the line at creating more duplicate threads promoting Adafruit's new competitive product or RP2350...

@WMXZ You bring up a really good point. If the "Freensy" had the same form factor and pin layout as say a T4 it would be more appealing to me to give it a try. Most of my work had been in robotics, especially rovers. Tend to use alot of pins...

I will second all of that! And as I have mentioned I appreciate all of the good stuff Adafruit has done and wish both you and the company well. I should note that I am doing this simply as a hobby as both for fun as well as trying to...

I don't have much useful to add to this thread, but since when did that stop anyone? ;) I tend to base my purchases on performance (for what I want, at the time) and price. Personality of the proprietor ... not so much. As I can't usually...

Hello all, After the startling Adafruit/Sparkfun showdown this week, I figure it's as good of a time as any to share my robot arm project on here that I've been working on sporadically for the past couple years. This is a small (if you consider...

Super cool :) Hall effect sensor rulez !

I second that. Having no sleep with a newborn can be really exhausting.

@ptorrone Ok going to be a bit different here. First congratulations on your new baby and good luck on getting any sleep. Second - have not seen anything that is 100% open source if you want to include the chip designs used on the any of the...

Using two 2.5 MOhm resistors (R1,R2) as a voltage divider creates a Thevenin equivalent resistance R of 1.25 MOhms at the non-inverting input. While this consumes very little power, it is generally not recommended for the LM358 due to its bipolar...

I'd think any builder/reseller would be happy to sell product to ANYONE. First rule of business : Make it easy for people to give you their money.

Indeed most other forums would have locked this thread. I'm not sure we've made the right decision, but for better or worse we're letting this play out as long as it stays mostly civil. Even more difficult (for me) has been resisting the urge...

For what it is worth, I also purchased ESP32-P4 and actually tested on my own and it runs circles around previous S3 model even at current 360MHz. But quite obviously it is slower than Teensy.

Yup, still using win7 on one machine myself. My DAW setup would be a complete pita to reconfigure, with no guarantee that all the VST and VSTi would still work, or my older version of Cubase, without needing to also "upgrade", with either...

Coming back to audio, Teensy is about the only platform that does multi-channel audio well. As I said earlier, my updated 8x8/16x16 audio board is open source hardware and software, and I'd be happy for Sparkfun to manufacture boards based on...

With great respect to PJRC and all the great work they do, I’d like to share a personal humble opinion. I think PJRC’s real strength is Teensy itself: high performance, small and easy-to-use hardware, and excellent custom libraries. That focus is...

2025 turned out to be a very challenging year for me. Sorry, I really can't share the details. I also can't talk about anything that might be development with SparkFun that isn't yet public knowledge. I do still have that WiFi hardware on my...

Understand there’s been challenges. This update from you gives a spark. I think many will be happy to see this :)

We decided to skip RT1170 and wait for NXP's next generation RT chip. PJRC signed a NDA with NXP, so if I knew anything about NXP's future plans I wouldn't be able to discuss details that aren't yet on their public website.

Thank you very much for the response. Can't wait to see the magic again :-)

In the light of recent discussion about "open source Teensy" I would like to ask @PaulStoffregen if there are any plans for new Teensy 5 from PJRC based on 1GHz NXP i.MX RT1170 or maybe other 1GHz microcontroller such as Renesas recent offerings...

Onboard dual 12-16 bit DAC. The 4.0 lacks this while the 3.2 had one. Maybe use a cortex M55 or M85? Faster than the M7

Not sure why your trying to advertise a competing product on the pjrc forum. If you honestly wanted a competing product to teensy. go the imxrt1170. Dual core. 1ghz. Everything teensy 4 has but more. But be prepared to to realise how much...

I've treated myself to a fairly cheap 2019 MacBook Pro to play with this stuff - so far it seems to be behaving fine, though I haven't really pushed things to the limits as yet. One thing I have been doing is messing with emulating the Teensy...

You probably know more about the backend sales and customer demand than me (obviously), but I do deal with very large numbers of teensies on my projects/products. (Love all around, I am not getting into drama) I would argue the reason Teensy is...

There are plenty of boards with lower performance and similar form factor and cheaper. RPico2 and all clones. Lots of Chinese STM32H503/H523/H562 and STM32U585 low power "pill" style boards, these are new, dirt cheap ARM M33 with floating point...

I messed about a bit, and if the static instance of usbMIDI is weakly defined, then the user code can define its own (strong) instance which invokes a different constructor. So something more consistent with the MIDI class would be possible.

Yes, but they are Linux based. I need bare metal, without Linux interfering and adding latency, long boot process and host of other stuff I don't need. Teensy is just perfect. If only it was faster. I was hoping for 1GHz NXP part (NXP i.MX...

For perfectly smooth ramp, you would need to adjust volume on sample-by-sample basis.

FWIW: there is browser called "Supremium" (Chrome based), that implements its own HTTPS stack independent from OS and allows to browse modern sites on Win XP without headache. I have to agree that Windows is really good in maintaining compatibility

But ESP32-P4 has hardware (single precision) FPU and it is 400MHz dual core part.

I am doing crazy amount of multichannel audio DSP real time, including real-time analog circuit simulation (nonlinear differential equations).

Personally, I need more computing power, so I would welcome microcontroller in the 1GHz range. Anything less than that is step back compared to Teensy 4.

I’m sorry to hear that things have taken such an unfortunate turn.

thanks tomas for engaging directly and not making assumptions. yes, we are an authorized reseller and have been since the beginning. we were likely the first reseller, and for years we were one of paul’s top channels. i’ve personally helped paul...

So you've come here on the Teensy forum to advertise your new products meant to compete with Teensy?
