Then, if you look at the source

outputflag = false;

This means that available() will only return true once as it is reset to...
Hi-
I am unable to get an output to the FFT in the example program "FFT Test" after making a small change.
The only addition to the program is adding a line in void loop, serial.print(myFFT.available()). Adding this...

I should have said, "nothing actually processes a connection" because the connections are technically accepted under the covers, it's just that your program does nothing with that information.
Well the 2 pairs of 13 pins tells me the board is likely designed for an original Raspberry Pi (later model Raspberry Pis now have 2 rows of 20 pins, but the first 13 pins are the same pinout as the previous pi models)....
I'm hosting another right now if anyone's interested. I'll be on for the next half hour or so, and longer if anyone joins.

Kris,
Thank you! It's been a long time coming, and I want to do even more with it... Crank velocity measurement, vibration measurement... A lot of folks see it and don't know what to think, I appreciate your remarks....
Hi! I'm a novice programmer. I've butchered the Bounce2 > more > BounceTwo example to make it so that it only performs an action (count up or down and print result) with each button press.
It works okay if I alternate...
Hi everybody,
Currently working on a custom 4.1 board that is using the RT1062CVL5B due to difficulties acquiring the RT1062DVJ6B. I understand that this model is not at all tested with the bootloader, but it is my...
Can you post the sketch you are using that causes this error? We can only guess at what is causing the error. Right off the bat it looks like it is trying to access POSIX style file functions which Teensyduino does not...
Hi,
I'm trying to adjust the volume while playing a WAV using AudioPlayWAVstereo, but ain't working for me.
AudioPlayWAVstereo is routed to a mixer and the mixer to a I2S output. Volume set by a pot and float on...
Hi all,
I'm working on a networked audio project, and naturally I'm faced with issues of clock drift and jitter. To date I've been using a delay-locked loop approach (something akin to that described by Fons...
Edit: My problem was bad connexion all is ok now with my SD card. I have a problem with a bad audio quality with the micro but I will test other cable or soldering...
@Richard: What kind of LEDs or interface do you use? Would be cool so see this running in large.
Have you seen this one?
Code here if you'd like to hypnotize yourself. :-)
Thanks a lot, a lapsus made me think uncommenting also meant deleting the # symbol :s
It works fine, using it with a TDA1387 after changing the corresponding line on the .cpp file.
I'm having some confusion because on one hand, your test program doesn't accept client connections nor reads from any connected clients (because nothing is connected), but on the other, you describe "all connected...
I follow the "if you don't want an explanation, don't ask" policy... Sometimes people ask me something without knowing how deep that rabbit hole would go, because they just want a simple and shallow answer, which is not...
“If it ain’t broke, don’t fix it” has always struck me as good advice :D
You could try doing a “portable” Arduino install and using Teensyduino 1.58 beta to see if the official fix works for you: I think the above...
OK, just had time to check and the startup.c file at this location: "C:\Program Files (x86)\Arduino\hardware\teensy\avr\cores\teensy4" has this "code change":

It looks like a "#" character is missing.
The way to enable these things is with a preprocessor macro, so use "#define" preprocessor operator.

FWIW, there appears to be two examples in the SmartMatrix library that use FastLed with Smartmatrix (FastLed_Functions and FastLed_Panel_Plus_Apa102). They run on my display once I select the proper shield and display...
I'm wondering what any ramifications I haven't thought of would be to changing the internal "write error" type from `char` to `int`. The API uses an `int`, as does the internal variable in the AVR, ESP32, ESP8266...

Right now, the urgent situation is IP numbers are getting reassigned, so we have to switch to different IP numbers. Both servers need to change IP numbers.
The path of least resistance probably would have been to...
Just got home and missed the down time.
Know this might be a loaded question but with the server change are you planning on making any changes to the forum or the product pages? Know that would be long term though.
Some documentation or help would be very Wellcome. the detection of serial stop is still a mystery, and I did not yet set multiple HID devices up, but looking what the
void HID_Input::hid_input_data(uint32_t Usage,...
Oh, looks like we're going to have about 20 minutes down time.... soon, while they do some sort of reconfiguration on the server. Should be just the forum down. Main site should stay up.
Indeed it's never that simple. The forum also needs to change IP number. Looks like it will become 66.232.106.something.
The hosting company is working on remote console access, which apparently never got set up...
Is there anything that we should be looking for?
That is, was this a "simple" server change or was there other things that changed as well?
My guess is simple is never simple!
I noticed recently that you...
Hi,
I have Teensy 4.0 with ADS1256 and USB filter to remove noise. I want put it on one board. Important for me is send data to PC via USB. Now I have connected cutted usb cable from teensy, connected to USB filter 5V,...
Funny I just tried 111.0 (64-bit) in windows and am seeing those same darts when using the built-in viewer in Firefox.
Microsoft Edge does not show those darts when using the builtin viewer.
Pretty much did what @defragster did with going to the new server location and trying the cart. So ditto - seems to be working up to that point.

OMG just solved it! Was giving it one last go before setting up a vbox environment and remembered that I had a prior issue when I compiled a program using the Audio library with the compiler set to debug. The compiler...
This sounds very much like the startup bug, might be worth applying the patch linked in that thread.
It doesn't help that the Audio library version number hasn't been updated since late 2016, despite there...
Thanks for the comments and suggestions. My versions are (which should be good to go per your message):
Arduino 1.8.19
Teensyduino 1.57
Teensy Loader 1.75.

The server switch-over is at about 95%. Hopefully the site is all working at the new server (162.254.150.250)?
Question... are you getting the forum's notification emails?
If it works up to 128ksps, it seems more likely that the buffer is overflowing than the buffer logic for some reason fails at that value. Can you make the buffer larger? Does CircularBuffer::write return an error if the...
Now for some guesswork, since I don't know and can't reproduce the problem.
First, check which version of Teensyduino you have. In Arduino 1.8.x, click Help > About. In Arduino 2.0.4, click Boards Manager and...
I just released 0.19.0. The changes:
### Added
* Added `Ethernet.loop()` calls to the `EthernetClient::write()` functions when
the send buffer is full.
* Added Ethernet hardware detection to support (well,...
I ran it here on a Teensy 4.1 with PT8211. I've uploaded about a dozen times. Haven't needed to press the pushbutton on Teensy 4.1 yet.

This is driving me NUTS! I have two newly acquired and assembled PT8211(s) that I am trying to pair with Teensy 4.1 boards that are no Ethernet. One is lockable and one is not. The lockable has the PT8211 in a top mount...
Richard,
The pull up isn't hard. simply a resistor of the suggested value - 5kOhm across the red and bare wire to make the signal go high when the hall sensor is open. When it's closed, it will pull the bare wire to...
Yep, that's fine. It merely looks at what's in the library's library.properties file, and `lwip-master` is simply based on top of the current `master`, which is also currently at 0.19.0-snapshot. I didn't change that...
There. I just changed `EthernetUDP::send()` to return an `int` and pushed to the GitHub repo (https://github.com/ssilverman/QNEthernet). Could you retry and post which error code (the return value from `send()`) you...

I can confirm that `EthernetUDP::send()` does just about the exact same thing as beginPacket()/write()/endPacket(). The difference being you're using less internal memory with `send()` (there's a `std::vector` allocated...
This relates to a data capture and streaming application, where at its fastest (currently) a combination of ADC results, time stamp, encoder count and input byte are written to a buffer in the ADC data ready ISR.

Difficult to say what exactly is going on. But I suspect the switch is the culprit. Looking at the different corrosion spots, I can imagine that the internal contacts of the hook-switch may be affected as well,...
