Yup, and of course it's possible that the CPU gets unstable at some point.
That's why it's called OVERclocking.. NXP says more than 600MHz is too much. You don't pack 3tons on the backseat of your car, too. The...
Which problem with the IDE?
It should work out of the box. Own builds will not work with Teensyduino - it checks the version, on install.
There are no problems.
Something is wrong with your installation.
Do it...
I know we did some testing of chip temperature while overclocking and using a ILI9341 display. The test sketch we used was demo_sauce so overclocking shouldn't affect the display driver/SPI.
If the processing triggers it, the processing is the reason.. i.e. a bug in you program? SOme kind of timing problem, perhaps with interrupts.
"pass trough" involves some processing, too. the audio library does this in...

Hi everybody and especially Paul,
let me say first that I´m totally impressed of your work. Since Corona gives me enough time, I´m learning to work with arduinos. In my first steps I build a keyboard-controller using...
I'm using SPDIF3. It's a confusing issue because I've seen all of crashes, distorts and works fine. Distortion is the most common. I am doing a lot of processing - a simple pass-through may not trigger it.

Hello everyone:D,
It's been a while since I worked on the manufacture of an analog synthesizer totally controlled at midday.
Thanks to your help and support, I realize this project a little more every day.
Hello...
I came across same problem when I ported one of the product to Teensy almost 5-6 months ago.
I am really waiting for this feature as I have ported my 2 projects now to Teensy4.0 and 1 to 4.1 successfully but holding up...
If you guys tell me what chrashes (with a short example program) I'll look.. at the moment i think a crash of SPI is unlikely, too..
I remember it uses an other PLL. This thingy has seven of them...
@jonr: Ah, my fault: I was talking about underclocking from 150MHz up to 600MHz, that works properly!
But setting it to > 600MHz with the Teensy Convolution SDR causes big problems, thats true! But its not confined to...
Yep, Teensy 4.1 is my next stop. Problem is I need to create a BOB with the necessary connections for peripheral like serial,display, I2C, general IO and the CAN transceivers,
Strange, that is basically the code I tested with. I just tried a different placement of the speed changes and the program locks up (switching between 816 Mhz while processing and 528 Mhz when idle and the speed at...
It is indeed headless, but only if you run it with the "--dir=" option as documented on the web page under "Command Line Install". If you omit that command line arg, it will run with the GUI.

Hi Justin,
As I am slowly waking up from hibernation Ive picked up on this part. The bat_sd you have shared helped a great deal, only one var was not declared tRecStart. Its early days still but the next version will...
Though the problem with both the Octows2811 and the 74AHCT125 used in the Octows2811 is that they are for 5v lights, and the OP said that he/she is using 12v lights. If the 12v lights can be controlled with a 3.3v data...

I have now checked little how it checks for certain files:
It actually matches a The Arduino Version in arduino.txt with

Wow, that's quite a statement to make!
The Teensyduino installer provides that "headless" non-GUI install option specifically so you can automate adding Teensy's files to a copy of the Arduino IDE.

Not familiar with the M9N. Is it a dual frequency unit, similar to the ublox F9P? If not, I have one of those working right beside my desk as we speak. I could run some of those tests for you as a comparison, with or...

Hello Paul,
I published a few libraries which are trying to support also the Teensy platform, like IRMP, IRremote, Talkie, ServoEasing , PlayRtttl etc.
I installed a CI actions for them e.g....
Just as added info I went to the Windows APP store for the Arduino and noticed several things:
1. IDE Release date is 9/15/2016 so not 100% sure the version you downloaded is 1.8.13 you should double check by clicking...
Officially, no. The 2nd USB port is only supported in USB host mode.
Unofficially, I believe WMXZ published a library with the normal device mode code converted to use the 2nd USB port. As I recall, it was only USB...
Can you give me a small self-contained program (using only libs Teensyduino installs) which I can copy into Arduino (not PlatformIO) to reproduce the problem?
To specifically answer your question:

Windows doesn't allow programs to write to the folders where the APP software are stored, even if run with admin privilege.
As Defragster explained, Teensyduino needs to install patches to the Java code.

The 'download' link in p#5 notes which versions of the IDE are supported. For supported versions the installer maintains the needed java files to complete a working install on those known versions.

I dont use 3.5/6 or 4.1s :-)
Honestly whats easier? Copy a file (where is my card ????) to a SD (where is my card reader????) and plug it into a board (dont forget to make the SD Slot easily acessible - my Teensys...
Yes, but you need to use these longer pins and these sockets (2 of each):

These allow the longer board to mount higher...

@jonr: no audio glitches here while changing CPU freq while audio is playing. I am using I2S audio with ADC PCM1808 and DAC PCM5102 with the Convolution SDR code.
Usually this error happens on Linux when attempting to install into a distro-provided copy of Arduino.
Only the original Arduino IDE from Arduino.cc website is supported. The many modified copies from Linux distros...
Hi JayShoe !

Is this on Windows or other?
See this page for OS specific details in any case : pjrc.com/teensy/td_download.html
If Windows was it a ZIP or Installer from the Arduino site? Windows Store version does not work...
Thanks a lot for your clear explanation. I was aware that multiple I2C devices can share a bus, but I was wondering if the audio wouldn't be affected since it requires very high speeds. Not sure how the protocol works...
Right now we only use one core. MicroPython does allow both through the thread api I think.
I’m thinking about treating the second core more like a pio state machine. Plenty to do before we use the second core.
The content should look like this (plain and simple but with your version instead)

Hi I, am not able to use Teensy 4.1 with Arduino because Teensy4.1 Install will not Install. I found this error lib/version.txt file missing.
I would appreciate help.

Does anyone have a working example of adapting flasher4 to load .hex firmware from an SD card? I've spent a fair number hours reading through this thread, the code, and the instructions, and can't quite figure out how...
Looks like this should be fairly straightforward.
I've learned the hard way (many more times than I'd like to admit) about putting too much work into supporting a new platform or new tech before it really offers...
Hi Paul,
Thanks for the quick reply. It's 400 pixels total.
Can the Teensy 4.1 fit on the Octows2811 adapter?
It seems longer with 24 pins as compared to 14 pins on the Octows2811.
Please advise.
Thanks,

No, I was responding to the post.
The issue is the only reason I need to use the downloaded installer vs the "APP" is because of TEENSY. No other boards have an issue with the APP from the APP store so this is why...
I would guess that there would be a lot of value in teensy wrapper libraries that are compatible with the pico libraries. Ie, an easy migration path for users who start on the low cost pico and want to upgrade to the...
Did you create a "portable" Arduino IDE and try installing Teensyduino into that copy? That ought to be the simplest way to get Teensy working.
To fix this problem affecting all Arduino copies with any board, you'll...
Wow! Well thought out reply! You make a very strong case against. All practical and honest reasons. Using an RPi or equivalent is much more logical indeed.
But you busted my widdle bubble. :) :)

Linux on Teensy would be somewhere between "not worth the incredible effort" to "pretty much impossible".
There is no MMU, so you're immediately resigned to not-so-useful ucLinux. The best case (but unlikely)...
This reason why I showed this is because I can not compile anything. Due, Uno, Teensy, nothing.
When I select Teensy 3.1/3.2 and try to compile I get the exact same message.

A couple of times I've wished I could run Linux on a Teensy 3 or 4. Wonder how hard a port would be? Yeah, I know, Teensy is a different animal, but so was the RPi back in the beginning. One Teensy as a general...
Each of the 8 PWM slices have two channels for output. They share a divisor so they'll share frequency but have separate compare registers. So, 16 is fair I think.
