Heh, so about 10 minutes after my previous post I went and checked the mail, and my Person Sensors have arrived! :cool:

Great, if you do I'm of course interested to hear how it goes. My sensors were posted about two weeks ago but the tracking number is not working and I'm expecting them to get held up in customs for...

I've followed up here so this thread doesn't get too far off topic.

(Moved conversation from this thread)



Hmm, that's interesting, and somewhat surprising, as I was expecting it to be the other way around. The eyes without lids take longer to render than the...

I just checked my SparkFun order and rather annoyingly it is set in an "exception" state, I guess due to a change I made to it after I placed it, which I understood would resolve automatically but...

Ahh, thank you! I hadn't spotted the begin() parameters. Bumping spi_clock up to 48,000,000 increased the framerate to around 30+ FPS per screen. 60,000,000 hits as high as 40+ FPS, 90,000,000 even...

Thanks @mjs513 and @KurtE for this great library. I've been using it to good effect with my updated version of the Uncanny Eyes codebase(s). I've recently started taking a look to see if I can...

Thanks for all the additional feedback and your code changes. I'll incorporate what makes sense to do so and keep working towards making things easier to use and customise.

You'll be pleased to...

Thanks for taking a look at this, and for the detailed notes on the various issues you hit on the way!



I've never used the standard Arduino .ino approach, so I wasn't even aware that it needs...

Thanks! I've only just seen this so haven't had a chance to look at it yet, but will do so before I spend any time refactoring into a library/API.

I've made a bit more progress on my side,...

Yes it does. I haven't added that yet but would be easy to do so. I'm currently somewhat more inclined though to get things to a point where the eyes are just a library people call from their own...

Not yet, I haven't looked at performance much at all yet as I'm still working on implementing/testing the basic functionality. At some point I'll look at how much CPU is lost to that spinning and...

I got rid of that craziness in my codebase, so loop() now always just renders a single frame. That still might not be fast enough for time-sensitive work to happen since rendering a frame takes...

These are IPS panels, the same tech as most PC/laptop monitors, so if she can tolerate using a computer screen she should be fine with these too. To my understanding, migraines and epilepsy are...

Hmm I don't know much about it but I'm not sure how triggering epilepsy would be possible without some sort of rapid strobing effect? Generally speaking, the higher the frame rate the better. Most PC...

I've been continuing to hack away at the Uncanny/M4 Eyes code and thought I'd post a bit of an update on where I'm at:

I've managed to merge in a lot of the M4 codebase, as well as make other...

Aren't there a couple of gotchas with using ATX PSUs like this though? For example, I think I read somewhere that most ATX supplies require a certain load on the 5V outputs before you can use the 12V...

That eye is just the built in "newt" eye from Uncanny Eyes, which I believe originated here. But yes, that eye definitely has something of a Halloween feel to it. One thing I'm planning on trying out...

It's still very much a work-in-progress, but I've got a proof-of-concept working that demonstrates hot-swapping eyes at runtime:

There's still lots I need to do...

It's not so much the storage loading time I think will need improving, it's the various transformations required. E.g. look at the comment on the bottom of this page: "Note that using slitPupilRadius...

The M4 code draws one column of pixels at a time, rather than row by row, so their logic ends up somewhat convoluted. I just implemented a similar optimisation however. I keep track of where the...

It sounds like the performance I'm seeing is similar to yours then, thanks for clarifying.



That's kinda how I ended up where I am - I started by trying to convert the existing 128x128 eyes to...

Does this mean 42 fps per screen, or 42 fps in total, 21 fps on each screen? I'm seeing around 46 fps across my two GC9A010A screens here, i.e. ~23 fps per screen.

I've started thinking about a...

The screens I ordered arrived yesterday and they worked first go using the default set of pins in the uncanny eyes code. Very cool!

Oh wow, this looks like a fun project, thanks for bringing it to my attention. I might order a couple of these and see how it goes. I don't suppose anyone's tried adding a camera and face detection...

Where did you get the 300mAh figure from? Their datasheet rates them at over 3000mAh which is in line with my experience of them. Do take notice though of the chart on the datasheet showing their...

I've had a good experience with Energizer Ultimate Lithium AA batteries in temperatures down to -30C / -22F before (on Lake Baikal), maybe they could be worth a look.

I've seen similar problems in the past (intermittently, once every few months, where I'd get a seemingly random large numbered exit code) when compiling with CLion + PlatformIO and never quite...

Each square is really just the same thing as a 256 long LED strip laid out in a zig-zag pattern, as you can see from their diagram. The OctoWS2811 library doesn't care about the layout of your LEDs,...

The order doesn't matter with the WS2811 protocol. Each LED effectively works by "taking one signal and passing the rest on", so what you are planning to do will work no problem. Yes, you will have...

I have the same question but for Teensy 4.0 in the UK, which I can't seem to find in stock anywhere currently.

I see, thanks for the clear and detailed explanation Paul, that's really helpful.

> eg, with the OctoWS2811 library Teensy 4 pinlist feature

Funnily enough that is exactly what led me to this....

I've been looking at the OcotWS2811 schematic and OctoWS2811::begin(void) code in OctoWS2811_imxrt.cpp, and there is something that is puzzling me. As far as I can tell from the 74HCT245 data sheet...

There's a thread here that you might find helpful: https://forum.pjrc.com/threads/38988-Bat-detector

I use PlatformIO in conjunction with CLion and am really happy with the combination. I too had trouble initially with library dependencies, mostly because I was installing libraries via the...

Depending on your requirements you might want to consider nrf24l01 modules too.

Note that you can include libraries directly from GitHub as follows:



[env]
platform = https://github.com/platformio/platform-teensy.git
board = teensy40

Thanks bamos, I hadn't seen that thread and there's some interesting info in there. I was aware I could try to change the physical pins as a workaround but I've been trying to avoid any hardware...

If anyone else is in a similar situation, hopefully it's helpful to know that I've managed to get things working by doing the following:


Replacing the Audio library with the ADC library...

Understood, and my sympathies go out to you for the challenges the pandemic has thrown your way.

Given I'm not using the audio shield (I just need FFT on a MAX9814 microphone) I think my best...

Thank you h4yn0nnym0u5e for taking the time to look at this in depth, and thank you PaulStoffregen for providing a clear explanation for what I'm seeing. I apologise for not having spotted the...

Sorry to bump this but I don't yet have a solution and am running out of ideas. I've tried simplifying my code right down and the problem still persists:



#define USE_OCTOWS2811...

I have a project that is using (among other things) a Teensy 3.2, OctoWS2811 adapter and FastLED, with 8 channels of WS2812B strips. Each strip is between 72 and 86 LEDs long, 630 LEDs in total. All...

It is now 20 months later - is all the above still the case? It seems to be, as I can't get an FFT audio signal without AudioOutputI2S, and even then what signal I do get seems to be miniscule...

Thanks Paul. I'm using CLion with PlatformIO, so updated my platformio.ini config as follows:


board = teensy40

I have a project that's about 15k lines of code, using a Teensy 3.2 and OctoWS2811 board to control around 700 LEDs. My code is using FastLED 3.4.0 and OctoWS2811 1.4.0 to drive the LEDs.

I also...

Yep that was the problem, it's working perfectly now on pin 33 :) Sorry for the noise, hopefully this at least helps anyone else down the line who hits the same issue.

Aaaargh... just realised what the problem might be. I see here https://www.pjrc.com/teensy/td_libs_OctoWS2811.html that it says "Do not use" on pin 32 for the Teensy 3.2! Not sure how I missed that,...

I have a project with a Teensy 3.2 and Ocotows2811 that uses all 8 channels. Each channel contains between 72 and 86 WS2812B LEDs and my code uses FastLED v3.4.0 to control them. It has all been...

Thanks for the very quick reply and for confirming my suspicions. Sounds like it's time for me to do a bit of refactoring of my code to take that into account...
