That's decent from pi-hut too, thanks.
However the ones from Oak tree have just arrived : 18 hours after I placed the order. Can't really argue with that.

Thanks, Robin - they're a bit more expensive than direct from you, but not if I allow for all the other costs.. I realise Prime has to be paid for somehow. And I'm in a rush so it's all good :)....

I suffered that 5 week wait recently. I managed to hold off nagging Robin - I was blaming Covid-19 and the election post. Very glad when they finally arrived ! Now I want some more but unfortunately...

Many of the example code snippets have this at the top :

Serial.begin(9600);
while (!Serial) {
; // wait for serial port to connect. Needed for native USB port only
}


This is...

Can you place the samples in Flash and copy the current one into ram before playing it ?

Maybe this does what you want ?

There is C code here (other repos exist but this one looks most developed - please let me know if you find a better...

I spotted this happening again.
I found 1.5.3 had been released so have installed that and updated udev.rules. However, teensyloader is still using a lot of CPU if no teensy is connected. It stops...

I'm running teensyduino 1.5.2 on Debian 9.

Whenever there is no teensy connected, the loader is consuming CPU (currently 68% of one core).
It does this regardless of whether I unplugged a working...

Not really unresolved - my code seems to work fine with your fix.

I'm just curious as the effect of that bug : what does that counter do ?

I've posted to this old thread as I just had a problem with power-on for a teensy 3.6 and looked for other comments.

I was using a small switching regulator based on an MP2307. These are available...

Excellent, thank you. Confirmed working. Not only on Basic Test, but also with my original problem.

Which is puzzling, really - Basic test isn't much like my code, and remember that initial...

Your suggestion certainly sounds likely, and your screen capture shows both what I'd expect and what I'm getting in the 1.8.2 build. I was also sampling pin 2. And what makes the first led fail on a...

Help->about says teensyduino 1.40

I've checked in libraries (actually ~/Arduino/libraries since I'm on linux) but there's no OctoWS2811.

When I did the following error test, I still had the...

Here's some screenshots of 'Basic test' built with arduino 1.8.2 and 1.8.5. I only changed

const int config = WS2811_GRB | WS2811_800kHz;

to
const int config = WS2811_GRB | WS2813_800kHz;
...

I've just noticed that the OctoWS2812 library uses pin 12 for frame sync.
I'm using pin 12 for MISO0, but I'm not doing multi-teensy video syncing.

I can see that pin 12 is manipulated in the...

It's the SAM2195. Initially, I used a board I'd got from a kickstarter :

I later bought more...

I think the 6 pin are actually 2812 and the 4 pin the 2812B.

I got them from Ray Wu - I bought 60m in the unpackaged form (just 0.5m strips). He seems to have a good reputation amongst DIY buyers....

I have a project that needs a synth. I've prototyped it with a Dream device but some of the voices aren't good enough (notably violin). I've been looking at Fluidsynth but alternatives (especially...

The idea is that it doesn't do more than 1 transmission per millisecond, though I agree it's a bit dodgy. The message it sends lasts about 800us.

But while not calling that code stops the problem,...

I'm pleased to find I can give a very simple example - BasicTest from the OctoWS2811 library also has a problem with 1.8.4 but not 1.8.2. I'm using that unmodified on my setup (so not all the leds...

I have the code below to regularly send out some MIDI values. I'm also maintaining 4 strings of 360 WS2813 LEDs using the octows2811 library on a teensy 3.5.

Building this on arduino 1.8.2 works...

On the same system (now with ledsPerStrip at 750), I'm trying to use the nRF24L01 with the maniacbug RF24 network library. I'm getting a lot of failures, and it seems to be when the leds.show() call...

Yes, I realised I was wasting the memory - I'd had to disable the double buffering when I used too much earlier. I just hadn't realised I couldn't use all 64K for display memory.

The BBC don't credit it, but it's a Teensy 3.2 controlling the LEDs (it's only an AVR controlling the fingers ..)

http://www.bbc.co.uk/news/disability-36036642

I'm using teensy 3.2 to drive 4500 WS2811 leds. For $reasons, they're connected to only 3 of the outputs, so ledsPerStrip is 1500.

Yes, I realise this isn't the most efficient way to do it, but...
