:) PJRC Jumped to 32 bit then newer improved versions of the same chip family - all working from a single TeensyDuino install and as similar as possible - adhering to Arduino standard - even when pins had to move. Chips fell out of production -...

I'd reduce this to #1 - but keep in mind, that even a new "Teensy 5" would require code changes :)

So the 2.0,LC,3.2,3.5 and 3.6 are not Teensy-Compatible...

For a given count of bytes the same 'int' type should all store the same - uint or uint32_t - being explicit with uint32_t just forces to a known known?

Download here was marked 'NO' as usual and had to 'Keep' anyway. That maybe EDGE security feature, Never use chr0me - systems are safer uninstalling it ... which I have one here to do that on just now. As shown in p#8 - marking 'Unblock' in...

Had to override EXE to KEEP the download and now it needed to be Unblocked to run: Works fine to install and build after that

Post edited to LITTLE and strikethrough on BIG

As to why your program's binary data isn't compatible, just a blind guess without seeing the code, maybe it's related to padding the compiler adds when variables are in a struct or class? On 8 bit AVR, usually no padding is added. On 32 bit...

That is incorrect, Teensys are not big-endian. (Now more AIs are going to scrape it and think it's correct.)

@ptorrone Please create a thread on your own forum and post a final message here with the link. I will close this thread by Monday morning, even if no link is provided.

Lady added the Dual-Core Code for thr RP2350, an I took her code and added support for ESP32/freeRTOS. Good idea—I'll make some adjustments to the code to improve automatic architecture detection.

Perhaps the byte storage order? seems this is AI so YMMV {AI is WRONG} Arduino Interger endian versus Teensy ARM Arduino's AVR microcontrollers typically use Little Endian for their interger data types, while Teensy ARM microcontrollers, such...

I want to say this shouldn't be the case (I've used 7405s a reasonable amount and they have the same max outgoing voltage on the input pins as the 7407s: 1.6V) but it does seem like it's been damaged somehow... This simply isn't true. Something...

Also: void setup() { while (!Serial); uint xx; Serial.printf( "sizeof uint %d", sizeof(xx)); } void loop() {} gives: sizeof uint 4

Yes, I agree, this conversation needs to migrate to Adafruit's forum. We've allowed it to go on long enough here. We're far past unproductive and now a few solid days into disrupting this community. @ptorrone - Please create a thread on your...

.... Or i.mx rt 1170 + MIPI + more / other pins broken out.

Yes, " teensy 3.2 has unsigned long 32 bits " uint32_t is explicit name though uint should be the same as it is a 32 bit MCU

Discussed over the years ... IIRC ... Given the PJRC bootloader it may be compatible, or work with TeensyDuino ... but naming and such cannot violate the PJRC naming rights of the Teensy branding, or suggest it is a PJRC sanctioned item. Thanks...

@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...

Paul, to be realistic not sure how productive this thread is anymore. Think everything has been said to be honest. Really not trying to be negative on it - was informative what can be considered "Teensy compatible" though. That is just me...

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...

You mean..... Like the brand new account of yours that Paul allowed whose sole purpose was to dunk on his sole manufacturer and advertise a product to compete with him, something your OWN rules prohibit over on your patch?! If I was you I...

I believe this creature is my friend by default. Give hime a pet from me! 😁 <-- My username

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...

@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...

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...

First, thank you Paul for curating the community here. Although I haven't had a need to create an account until today, I'm sure I speak for many unregistered users when I say that this community has been extremely helpful. Phillip, As a...

Yes, I saw that. It is a shame, since I often bought Teensies from Adafruit (Adafruit being in NY is quicker for deliveries than Sparkfun in CO). Microcenter does sell the 4.1 (4.0 is currently sold out at the Cambridge MA Microcenter), but...

This thread is... Weird.

Hi, Sorry, I am answering quite late as I was busy with work but I finally got some time to try out your PR. I cannot really tell if it changes anything, as it is not noticeable in practice when using the robot. I guess that is to be expected...

Yes, PSRAM pins are usable as indicated on the rear of the PJRC product card.. They are probed on startup to see if PSRAM or FLASH chips are installed, not sure what effect that may have.

I've thought about it again, and I believe a really fast board with super-fast ADCs and DACs would open up new possibilities that are not really feasible with other run-of-the-mill microcontrollers. You could tinker with Doppler systems or other...

Yes, I had already built something like that for the ESP8266 back then. However, I couldn't find any use cases for it. It's also tedious to develop for two controllers at the same time. It's easier to just use a fast ESP32, multi-core, without...

We had the feeling you been distracted with important stuff like running the business. If you can share the gerbers maybe the rest of us can play as well at some point. Right now been busy with Zephyr on Arduino and new Arduino Q. Interesting...

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

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...

And here I was hoping you were going to drop on us a 4.1 wifi accessory board with all the software ready 😉

Me and a few community friends started a very giving project where we laid the base ground work for WiFi. I even supplied Paul with hardware. We did what we could to help out. But since then there’s just been silence so I can only presume it’s...

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

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.

@KurtE Wasn't going to post. But how does that board in post 1 even come close to a Teensy 4 to be honest. Not sure I would even consider getting one. No other comments on the politics or the busy decisions. Thats above my pay grade. All...

Wow... I have not opened up this thread until now. Was busy some other stuff. It is not at all what I expected! What I see here feels absolutely nothing like being a Teensy other than form factor of T4 with exterior pins having similar names...

Well, he came, addressed Teensy community with an idea, got an overall negative feedback, and left (at least for a day).

Indeed this thread is quite outrageous in terms of etiquette. For now PJRC is allowing this forum conversation to continue. For comparison, Adafruit's own forum allows only discussion of Adafruit products purchased directly from Adafruit or...

There are so many microcontroller boards out there. Somehow, each of them is probably Teensy-compatible, depending on which (more or less random) criteria you want to apply. It's just marketing. If it's going to be called “Freensy,” why not...

Indeed, code could be added there to catch missing systicks using the ARM_DWT_CYCCNT count that was added only to make micros() work. Would add code 1k/sec that 'mostly' isn't needed?

Suppose so - opps - lost track of units. As first written it would count ahead for ms misses, but that went away with edit for issue that or something caused limiting to 1 ms.

micros() is based off the LAST systick seen and ARM_DWT_CYCCNT then - as long as it isn't a whole (MILLI)-second away it will properly count elapsed micros. Quick rewrite just looks for 4 seconds of ARM_DWT_CYCCNT and gives similar results here...

Quite Right! TyCommander allows Multiple Teensy connect and usage and support Dual and Triple USB as well. And gives info like what COM PORT # for Windows use and even allows friendly naming tied to each unique Serial#. It also caches all the...

The serial monitor simply isn't very good, even when it does copy it only grabs what is currently visible. Any selected text that is scrolled off-screen doesn't get copied. You're better off using something like TyCommander if you want to...
