Please forgive me if this is an obvious issue that I should understand by now considering I have been working with teensy and arduino since teensy 2 came out.

I am designing a led project around...

Bumpity Bumps

Exactly that:
Are there any solutions to program the teensy 4.0 wirelessly?

I have a battery powered prop that will be inside of a case that will be very difficult to program again and again...

That is exactly what I realized I should do, thank you for re confirming that. For the sake of simplicity and speed, I've decided to use multiple Teensy LCs because they are fantastic and so cheap to...

You are awesome! Thank you!

Was the timing repeatable? and have you ever timed it?

Can I change PinMode(Output/Input) in main loop? ... Safely?

I am working on a project where I would very much like to have to only use 1 digital pin as an Input and Output, not simultaneously of...

Anyone know of a 16 channel shift register that can notify the micrcocontroller via external interrupt of a change in state of one of the inputs? That would be a fantastic solution. I will never use...

Hey guys, I am designing a large midi board project that will utilize 64 rotary encoder/push buttons. Has anyone done anything similar using the Teensy 3?

My biggest issue I think may be latency...

Great to hear!

As far as a desired FPS, I have no set number. I just need it to be as fast as possible, then I will set a fps limit. The size of each frame is roughly (2000 bytes * 2), which is no match for T3.1

Hey guys I am looking for project guidance...

My project is going to consist of 4 microprocessors purely for speed. 3 x MK20s and an atmege328 for communication (USB, Bluetooth, IR). Of course I...

I am just using a camera, not using anything that actually determines when leds trigger ect... I can post an image soon to show you an example if you would like.
But basically I am storing a pixel...

Well they display colors very well and correctly, but when I display a bitmap or pixelmap of say a square, or any straight line and take a photo of it with a camera it is very noticeable that they...

I know OctoWS2811 is designed for multiple large led strips, but do you think it would be ok to use for just 28? I am experiencing a lot of weirdness and instability with both fastspi libraries, it...

I just saw that, Congratulations Paul!

Ok great thank you.

Works great, T3 and Visual C#

Sorry for the vague question, I didn't realize there were different ftdi chips, I also don't fully understand this.
Specifically this one: https://www.sparkfun.com/products/9873
which is FTDI...

I don't quite understand, do I need a MAX232 when I use an ftdi basic for the T3?

Is it possible to communicate with T3 using the existing usb (usb0-DM, usb0_DP) and Visual C#?

Exactly, Paul never misses a beat.

Probably. Mi issue though is that I needed to keep all of my original code, and the way I talk to the strips is a bit different than with fastSPI_LED. Also fastSPI has a much faster fps than the...

Use Atmel Studio 6 to program arduino compatible baords. Imports arduino libraries ect...

I tried this with a 1284p and ended up getting a...

Got it! :D

If anyone else is in the same boat:



/*This:*/ FastSPI_LED.setChipset(CFastSPI_LED::SPI_LPD8806);
/*This:*/ FastSPI_LED.init();
for(int i=0; i<86; i++){

Hey guys,

I am working on a project where I originally used the fast spi lpd8806.h library to control led strips, I want to keep my original work and continue to build the project using...

I can't find for the life of me how an SD card reader actually works anywhere on the web, if I could I wouldn't post this question, so this is the first place I could think of to ask.

Thanks in...

I want to be able to plug my project box in via usb and have a computer basically access an unmovable micro sd card like it normally would "having nothing to do with the teensy" Will I be able to...

How many frame/second are you getting out of the WS2811?

Did you try restarting your mac? just try it, its a mac. Itll take 30 seconds.

Whenever that happens to me re-booting my macbook pro always fixes it. Either that or you have have the wrong port set. I use: cu.usbmodem:12341

I want to use an led strip which uses MOSI(11) and SCK(13) running through fastSPI library, I also want to use an sd card that stores information for the settings and that uses MOSI(11), MISO(12),...

Yeah that would be the best way to go about it, but my issue is that the led strips ONLY use Mosi and SCK, it doesn't use a select pin - (fastSPI).

Even easier: I am still new to electronics but...

Will do :)

Can these pins be assigned and re-asigned during runtime?

I am running led strips using pins: 11(DOUT) and 13(SCK)
I want to be able to access an sd card using pins: 11(DOUT), 12(DIN), 14(SCK),...

Thank you for the great explanation Paul :D any chance you can share the exact crystal that is in the teensy 3?

Actually I have two questions-

1. How accurate is the clock (timer based interrupts) running @ 96mHz? I want to control leds that will run from a sort of timeline to go along with a 15 minute...
