    VGA output via FlexIO (Teensy4)

    I'd like to do a similar ball "demo" like the Amiga "Boing Demo" had in 1985. The demo was for the 4ch into stereo output too.

    Any reason the SPI library seems to have a minimum frequency around 1MHz?

    I'd like that feature to be able to use cables too! (I also wonder what the SPI signals would "sound-like" if you lowered the clock to 1kHz and fed it to an audio amp...)

    Using ChatGPT / OpenAI for Arduino help

    About ChatGPT code offerings: I appreciate the comments into it's replys added based on the query psudo-code... ...but mostly the orthogonal formatting and correct indentations throughout the code. [The "copy code" button in the HTML is a nice Human touch too!]

    code teensy 4.0 print cpu usaged

    Yes. That last sentence seems just like what a GPT would respond with: "I hope this information is helpful! Let me know if you have any other questions. " ...but thank you to anyone of you humans who is just a friendly as GPT has been!

    PS2 Keyboard Library compatability with newer ps2 keyboards.

    Thank you for the quick reply Paul. The hyperlink landed me deep inside a vast catalog (I remember when the DigiKey catalog was 3/8" thick paper) showed me lots more interesting pre-fab prototyping HW = Awesome!

    PS2 Keyboard Library compatability with newer ps2 keyboards.

    Hi Paul. I really admire the PS2 Keyboard prototype here: https://www.pjrc.com/teensy/td_libs_PS2Keyboard.html I like to prototype and would like to know where the threaded 90 degree angle brackets can be purchased, or what their part number or correct name is so I can search for them. Thanks...

    Well duh, the Teensy 3.6 is NOT 5v tolerant

    Which means only Red or IR LED's will forward conduct to illuminate right around the I knee, and bonus: no series resistor required!
