    p#32 - Windows Perf Issues? Without a specific case - and not knowing a single cause ... perhaps link the doc pjrc.com/teensy/td_download.html#antivirus_performance_issue to the posts here on this thread in case they lead to a solution

    Thanks for taking the time to make these screenshots! I really appreciate help with Windows stuff, as I mostly use Linux and occasionally Macintosh.

    Should be updated to say that this works on T4.1 as well.
    Updated to state Teensy 4.1 compatibility, and explain bottom side pads on Teensy 4.0.

    @Degragster - Any chance I can talk you into re-writing the guidance in msg #24 in a step-by-step style?

    I want to put this on the download page. But the conversational style of msg #24 isn't a good fit for the web page. It really needs a brief and clear description of why to use this approach rather than Mark's 8-step process, and then a set of specific steps to follow to accomplish it.

    Remember, I don't use Windows. I'm really looking for text & images to copy verbatim into the web page, so I don't mess up some subtle but important Windows detail.

    And wish the T4.1 page would refer users to the T4 page for memory stuff or a copy of it also showing external memory...
    Added a link under "Memory Expansion".

    Eventually I want to move that memory layout stuff to a dedicated page and expand it with examples. But hopefully this helps until I can put more time into the website.

    No mention of Teensy 4: "OctoWS2811 requires the DMA (Direct Memory Access) engine which is available only in Teensy LC & 3.x."
    Updated, now says "Teensy LC & 3.x & 4.x".


    Also, it appears from skimming your OctoWS2811 Teensy 4 code and reading between the lines on some forum posts you made that OctoWS2811 running on the Teensy 4 can drive more than 8 outputs, but there's no documentation to that effect.
    Under "Hardware Requirements" the page does say:

    Teensy 4.0 and Teensy 4.1 can use any group of pins, even groups smaller or larger than 8 pins! In Arduino, open File > Examples > OctoWS2811 > Teensy4_PinList for details. If a custom pin list is not specified, the same group of 8 pins as Teensy 3.x will be used by default.
    I've added "Teensy 4.x boards support use of any set of pins, not limited to only 8 fixed pins. See the Teensy4_PinList example for details." near the top of the page to hopefully make this more visible.

    in
    "Teensy 4.0 can be programmed using the Arduino IDE with Teensyduino add-on."
    change 4.0 to 4.1

    yes I'll look at that batch of screen shots and see if I can make some step-wise sense of them ...

    Just saw this page has a "Key Features:" table missing T_4.0 and 4.1:
    pjrc.com/teensy/index.html

    In fact "Key Features:" table entry for T_3.1 is there not 3.2

    1. The libraries page only shows Teensy 2.0 through 3.x
    2. The code in the section "Pushbuttons To Control LED Colors" of tutorial 3 has the comment "// use mode one when the first button is pressed" which should read "second button"

    This page is for Teensy 2 only, but there is no indication that it is not valid for Teensy 3/4 which leads to misunderstandings: https://forum.pjrc.com/threads/64702...ntrol-register

    The Teensy 4.1 card back side isn't published, in either image or PDF:

    Actually it would be nice to update the back of the card to have some similar information like the back of the card T4 and T3.6 with maybe showing the USB Pins, The internal: ON/OFF, Program, ... pins,


    Another minor web page thing is the T4 page (https://www.pjrc.com/store/teensy40.html) starts off saying: Teensy 4.0 is the latest Teensy, offering ...
    But now the T4.1 is the latest

    And of course there are rumors of a new Teensy using the same chip but with a new form factor (micromod) that might show up some time.

    That is always the problem of labeling something 'new'. I recall when I was an exchange student during the summer of 1978 in the Netherlands, of seeing a church built in 1380-1408 and rebuilt a few times afterwards labeled Nieuwe Kerk (new church). The Oude Kerk (old church) was built in 1213-1306 (and renovated a few times) is evidently still standing. I would have to imagine there are newer churches built since then.

    I'm planning to rewrite the product pages "soon". The Teensy 4.1 pinout card back side will come later, probably late December or early January. Most of the website is a work in progress, but at this moment I'd like to talk about what to put on the product pages.

    In prep, I started a lengthy outline / template list of sections and sub-sections I want to include on all the product pages. I also spent some time looking at the product pages on Sparkfun, Adafruit and Arduino. Adafruit's page are most similar to what we have now, usually just a list of specs, some description & photos, and links to other pages on the site. Arduino & Sparkfun use tabs, but some are long info that requires scrolling anyway. I'm feeling inspired by some of Arduino's pages where the "documentation" tab lists all the hardware features briefly. For Teensy 4.0 & 4.1 that would become a very long list, but maybe long is good if the info is clearly arranged?

    So my open-ended question at this point is what info should go onto those product pages. And a lesser question is how detailed should it be on those pages, versus a brief mention and links to other pages with more in-depth coverage?

    It would be useful to mention what are the specific defines for each chip to use with #ifdef.

    One thing that would be useful in the web document, but it probably doesn't need to be at the top is a brief list for each of the boards of what shields work without modification, which work with some modification, and which don't work at all. Or possibly links to a common meta page about shields.

    For example, with the prop shield:
    • Teensy LC: DAC output works for the Teensy LC, but a lot of the audio library does not work;
    • Teensy 3.2: Works great;
    • Teensy 3.5 & 3.6: Works great, for sound you need to run a wire from DAC0 (A21) to the DAC pin on the prop shield, and you don't need to connect the other back 4 pins;
    • Teensy 4.0 & 4.1: Sound does not work at all, no need to connect the 5 back pins.


    It may be useful to have a meta page of useful example pages, starting with the ever popular blink, and then listing a few examples to show off what the Teensys could do (i.e. pointing off to the audio example, etc.). You don't want a long list, but it would be helpful to have maybe a top 10 list of things that can be done.

    Brief specs and details are good to start with, but there should definitely be links to more detailed information either on separate pages or further down the same page.
