Very possible its Windows. As mentioned above, no problem when using iPad as host.

Bummer - that is not right. Did you try the linked Blink sketch? It support Send and Return over USB. I should update to do some unique blink on incoming USB in case it ever works one way somehow. It isn't noted or...

I can upload and run a sketch no problem, though I do have to press the button every time when the board isn’t set to HID mode. Also, I have no serial communication even when set to Serial.

Indeed - if the GPU flies off - supposing it has one and that Paul didn't buy AMD just to get a low end machine - making the fan run then the App may be the issue. That should show in the USB traffic under analysis...

It sounds like Windows enters into the 'condition' not Teensy.

Thank you Oddson for the offer of help :). I was able to finish the code with much help of a friend. We have it was a array and a incremt what the states by turns and then return to zero. And it works fin. Thanks again...

Scanning the code I see the problem might be :: Const TEENSY_POST_COMPILER As String = "REAL_teensy_post_compile.exe" ' "C:\Program Files (x86)\Arduino\hardware\tools\REAL_teensy_post_compile.exe" That is not where...

Hey Gremlin; Thanks for getting back to me, I have tried to check the same code on different teensy boards, the result is same. I tested the digital pin voltage too, it reads 3.3V when power is 3.3V also 5 V when the...

I started off using the SanDisk, but was having to reformat the card every couple of weeks or so as all of a sudden I couldn't read it. I switched to ADATA and have never had to reformat, but get the stutter. I am also...

Sounds like TeensyDuino 1.42? Not made clear - not sure how the Mac menu may differ. Teensy is HID in program mode and when programmed that way. Uploaded as a Serial sketch can have HID too, but TD 1.42 can see HID....

Paul: I added this to my TeensyDuino 1.42 IDE and I'm now seeing :: That prints as the building starts and after it completes:: Unable to open COM10 After the build the upload worked and the T_sermon connected...

Great response Paul. Thank you. I'll have to look into it tomorrow and if I have any more questions, I'll be sure to ask them here. :)

Kurt , what i am trying to do , ( in the wrong way for sure ) it is to read the address 0x000001A4 that it is the corresponding : VECTOR_105 // 0x0000_01A4 105 or IRQ 89 Port control module Pin...

Oops sorry macOS! I only see " (Teensy 3.6) Serial" in the port list. This is after I programmed the Teensy with “Serial” as the USB type.

That seems cool but a bit more complicated than what I wanted to do. Either way I'll check it out. Thanks.

Yes. The answer is yes! The OctoWS2811 library comes with a SpectrumAnalyzer example that does exact this. https://github.com/PaulStoffregen/OctoWS2811/blob/master/examples/SpectrumAnalyzer/SpectrumAnalyzer.ino ...

This isn't windows? What version of TeensyDuino? Version 1.42 is the latest and has two sets of device listings on Tools/Port. Was the UDEV rules added if needed? Is there another terminal program connecting to the...

Hopefully the same read of the HEX (?) file gice the same results. But the ARM code should come with Teensy and always be in that spot. If you are going to really hope to make an 'advanced terminal program for...

Cool! I wonder if there is any difference between the toolchains. I'll have to try it both ways and do a diff. ;-)

That sucks. I know ways around it, but they all make the PCB cost more, and I don't see that being done. I very likely wouldn't make the decision to add that much cost to the PCB.

Force an update check - not likely related … { but … win update .165 may not be pretty - I've gotten 4 machines in recent days on .165 that were acting slow and ugly for the user. And on the TaskMan/perf page it...

I'm no expert either, but I at least know many of the issues and were to look. Also soldering is so second nature to me and I don't think of how to do it. I've been doing it since I was 8. PS, buy the high quality...

Or maybe MS is hiding their background update tasks. Winvir shows .165 and I don't have any new updates this week showing up in my Updates history, I might force an update and see if it changes anything. Am I...

I rebuilt to use:: {from the ARM toolchain - not the AVR- version} and copied to t:\tmp from :: "T:\arduino_1.8.5_142\hardware\tools\arm\arm-none-eabi\bin\objdump.exe" ...

It seems you bought an AMD laptop? Does it have AMD video GPU? Something may be firing that up adding HEAT in the box. If you right click a column heading on that 'Processes' tab you can Add '% GPU' and 'GPU...

You might find the libraries here helpful - https://github.com/trustcrypto/libraries OnlyKey uses tweetnacl and a bunch of other crypto libraries that are teensy compatible. Tweetnacl is great but pretty slow, I'm...

Awe Snap! I think I'll have to add another step in the required steps. Try to add WinAVR to your path variable. If you don't have WinAVR then I suppose you will have to get that too. This is what is the pertinent...

Something that might help, is once it gets into that condition, if you open a serial terminal it will typically recover for a short time (10 minutes maybe?). it might give you a chance to see it fail again without the...

I added unpacked sensor configuration and data structures to be used in within the software: https://github.com/bolderflight/RAPTRS/blob/master/embedded/common/global_defs.h They're in global_defs because they'll be...

No protocol analyzer yet - just seeing initial testing. Here's 2 strange things. First, I rebooted (actually several reboots due to a big Windows Update) but left the Teensy running. When I ran the program again,...

Win 10 here. Resultant EXE was 12KB versus REAL of 25KB. I did my best to read and follow the steps. OH WAIT … I'm using TyCommander - it may replace/subvert the post_compile process … loading the...

It's cool to see someone interested so soon! I am happy to help... Did you follow the 6 steps outlined in the README.md (also included above)? I am using Windows 7... BTW -Joe

At least is wasn't twice as long. Did the USB analyzer catch the traffic usefully or suggestively?

I was able to reproduce the problem here. Takes much longer on my machine, about 75 minutes.

Awesome for Windows! I just installed VS17 so I wanted something to build. It did: But I don't see a map - just the prior RAM/FLASH use numbers? Did I miss something? I downloaded the Zip - and the solution...

Most times, it is most important to look at the very first error message. All following might be secondary symptoms. Thus, we should fix the first problem first: That looks like an error of the Arduino IDE and its...

Minor update to prior code in use: I changed the 512 buffer to 1024 bytes wondering if that might work out better - it does not. The above numbers are below in the cryptic printed format: 13231 << avg us 67700 << #...

Don't buy cheap SD cards! I was using an Apacer Class 10 card, but when I replaced it with a Sandisk Ultra Class 10 the stutter vanished. Memory and processor usage also halved! So... Don't buy cheap SD cards!...

I spoke too soon. Still stuttering.

I was wondering why it was suggested to try ALL digital pins … looking again with that in mind perhaps it was expected there was a local array : DIGITAL_PINS Where if you had 7 digital pins to setup:: #define D_PINS...

I added a 10uF Electrolytic and 0.1uF Ceramic cap to the Teensy setup and the stutter seems to be gone. I still need to verify this with a few more files, bit for now it seems a current spike during high processor usage...

Not sure because if I change it I get the error message: 'DIGITAL_PINS' was not declared in this scope DIGITAL_PINS is in the line right below D_PINS

Suspect abbreviation for 'D_PINS' count was to be :: NUM_DIGITAL_PINS ??

I did what you said but get an error message: 'D_PINS' was not declared in this scope Here's the code when put together: #include "Wire.h" int leftMeter = 20; // left meter (hours) is attached to pin 5...

Ah, ok the plastic bag serves to prevent direct exposure. In my case I did not test before/after on the same element, but looking at the spectrogram output the higher frequencies were definitely attenuated in the signal...

FlexIO and XBAR do seem cool and mushmaking for the brain thing. Paul has noted what he expects he can present on the 1.4" T_3.2 sized board. One thing mjs513's mock up doesn't express - AFAIK the MCU package is...

Quick question - Looks like I may have a path problem here? Where should be the OctoWS2811 programs be located for the Arduino to fine them everytime??

Thanks Paul, I think I understand this issue better now but I do have a question about this: What do you mean by 'many downstream Teensy boards?' 480/12 = 40 Teensys? I cannot find a multi TT hub that has more...

Are you using a clone shield? Some have serious problems. https://esp8266-notes.blogspot.com/2017/08/defective-arduino-usb-host-shield-boards.html I guess Teensy 3.2 is 5V tolerant so a shield should be OK. The...

Hi Paul, I've tried a bunch of experiments to try to get it to fail faster. Its been a futile exercise, it seems pushing it harder is making it run longer. For instance, cranking up the BPM to 650 and putting a serial...

The more I read on FlexIO and XBAR the more mushy my brain gets, but they look very interesting. I already can see where they would provide low level hardware support for coordinated motion control in a robot or 3D...

Running the test here, first time. Guess I've got 40 minutes to go until the problem....

looks like its used to stabilize the circuit’s signals, alot of electronics have these pots, even televisions. once adjusted, theres no reason to tweak it again unless someone plays with them or the daughter board...

Thanks Eka. I do not have much experience soldering components as small as these but I will look into the tips you mentioned. Sometimes, an LED will stop working after it is already on my project so some of the baking...

Following up on Kurt's last - in case I understand any of this - it seems like it is an attempt to prepopulate the RAM vector table to point to My_F()? But that vector table is only enabled after the PJRC processor...

That will be a nice addition to the board in case any one wants to use UAVcan in the future. I have tested the lib on a 3.6 and seems to work no issue. There is only one problem that is flexcan library related.

This group has been such a huge help and offered wonderful code and advice - so I thought I would share some images of the 14 we have in the field at the moment - we built in the capacitor and resistor into the signal...

Hi again @M.Melani, I will be honest and say I have no clue what this would actually do: #pragma abs_address:0x000001A4 void(* My_F_handler)()={ My_F }; #pragma end_abs_address What is address 1A4? What do...

Hi Paul, I’m having the exact same issue. I increased the memory allocation but no luck. The max usage never peaks above 8. I checked the CPU usage and after the stutter it shows the max at around 372. Not sure...

It is meant to be used inside a plastic bag which acts as an outdoor case ;-). You are probably right that it would be wise to put something inside the bag to soak up humidity. Did you measure how frequency...

@M.Melani - re your PM - the notes about the debug library were to have any FAULTS caused by your attempts to code this captured and reported out to the Serial Monitor. I was assuming the Teensy is faulting and just...

I am curious how that mic performs in outdoor 24/7 recording situations. I have previously done that kind of ambient recording using a sensitive electret mic claiming 80 dB-A SNR...

I would say that the best thing is what is called "security by obscurity". i.e. keep a component or piece of code secret.

so happy I was able to help someone and not just ask questions :o

Hi Mike, the Raven is typically only used in research labs and businesses, so they are priced accordingly, I'll shoot you a PM and we can talk hobby prices for the Raven. I actually set aside room and pins to add CAN...

I have a slightly different question, but directly related to the title: In the audio design tool it says about the SVF resonance() function, "You must attenuate the signal before input to this filter, to prevent...

There a discussion on generating a BPM clock signal for midi here: https://forum.pjrc.com/threads/50559-How-to-generate-USB-MIDI-clock-with-Teensy-2-0 Might be a useful start

Cool, thanks. This did the trick ... Getting output on all 8 channels now, I guess I must have done something wrong when stuffing the buffer. Now on to trying to hook things up to the PDB / audio library. FWIW,...

Do you want me to help figure out what's wrong? The very first step is to post a complete (and hopefully small) program which I can run on my CS42448 here, to reproduce the problem.

Hi, Thanks. What's not clear to me at this point is how to actually use the library and for instance activate oscillators or any other function the original SID chip can do. Cheers, BC

How is this going? I would like to experiment with using phased lock loops to reinforce a frequency with an arbitrary offset, was planning a hardware logic approach but I wonder if a software approach would work...
