Hi,

has anyone a link to a good PoE solution for the Teensy 4. I mean a ready to solder or stack on pcb breakout PoE board with approx. 13 Watts.

Thank you

Torsten

...ok...thank you...will try....

Torsten

Ah..thank you...

So when i am using e.g. attachInterrupt(digitalPinToInterrupt(2), pin_ISR, CHANGE); it will use which interrupt.?..it says on the teensy4 pinning card that all digital pins are...

Hi,

will teensythreads and interrupts work together, or will interrupts via attachInterrupt to a pin ruin the threads schedule?

Thank you

Torsten

Okay....then the question other way round....

What is the INPUT_PULLUP parameter exactly doing in the teensy...(internal wiring a pullup resistor) ? Is this only for inputs ?

Thank you
...

Hm....okay....

had the same question..also for CS signals for SPI...or digitalRead switches switching to ground....are there external pullup resistor needed or will the INPUT_PULLUP in the pinMode...

Hi,

I will try this....thank you very much...

@fab672000,

Thank you for your quick answer...yes after thinking about a bit this seems to be possible...but how to 'grep'/consume a semaphore that the thread blocks and then release it again in...

Hi,

is it possible in TeensyThreads to start a thread and suspend it as long an event happens (e.g. interrupt) then process the things needed from the interrupt and then suspended (sleeping) again...

Hi eagleman,

thank you for doing and sharing this....
But is it possible that in the library you uploaded the T4.1 is missing?

Again thank you

Torsten

Great...big thumbs up....thank you

Torsten

Hi vjmuzik,

thank you very much for doing this nice work....
Is the library able to do multicast ?

Thank you

Torsten

Hi,

I want to use a Cy8C9560A port expander from cypress. I want to talk to it via the i2c lines....it says in the manual that the i2C master has to support i2c clock stretching...not really sure...

Hi Paul,

thank you for the quick answer...will then wait....

Is there a recommended ethernet magnetics device you can suggest to attach to the ethernet pins?

Thank very much

Torsten

Hi,

not really sure if i missed something on the above topic...The thread for this device is closed with the comment everything is now done/fixed... so i try it here...
Due to the fact that i am...

...all my dreams become true.....ethernet....thumbs up!!!

Thank you

Torsten

Yes, i saw this thread...the next teensy will then be "the hammer"....

Hi,

I read in the fact sheet of the T4 MCU (1060) that the MCU has a pixel pipeline for 2d graphics and a RGB parallel interface...
My question is now if/how this is accessable in the actual T4...

Exactly,

I am doing cockpit devices for flightsimulators....with bare metal programming and connectivity with ethernet...at the moment i am using the SPI solution together with a WIZ IO...but for...

Hi Paul,

glad to hear this...appreciate this very much....sure...there must be some peace of code on the sw side...lets see...

Again, great work what you are doing....

Torsten

@vjmuzik
It seems that we will never get a native ethernet interface for the teensy...;-) ...but never the less, teensy is great....and it is great to see the future plans for it....

Ah ok...

Thank you...

Torsten

Ahm,

not sure if this is a stupid question....how do i connect this USB2Ethernet adapter to a Teensy? Just plug it into the USB connector of it?

Thank you

Torsten

Hi KurtE,

thank you very much porting this to teensy 4!

Torsten

Hi KurtE,

Yes it says unknown chip...i thing due to an #ifdef....and i really do not understand what the purpose of this is...so i can't fix it...

Thank you for your help...

Torsten

Hi,

is there any chance that this great library will work together with the teensy 4 ?

https://github.com/crteensy/DmaSpi

As far i understood with this library you can "deligate" the SPI...

Hi,

omg....you are great!!!

Thank you 1000

Torsten

Hi,

i will use it in vacuum of outer space behind the van Allen belt for the next lunar mission (Apollo 18) they need a computer without error 1202 during lunar descent ;-)

Thank you for your...

Hi,

this great piece arrived today….wow...i love it....started with blink etc.. to get a feeling how it works…

My endproduct where i want to use it will be "in a box" so i asked myself, due to...

Hi,

anyone tried TeensyThreads on a teensy 4? I tried it and get an error that says that IRQ_PIT_CH0 is not declared…

Ok thank you for your help...

Hi,

on the pin out card for the Teensy 4.0 i can find the MOSI1 and the SCK1 pins on 26 and 27 for the SPI1 channel. Are there also a MISO1 and a CS1 pin for that channel...or do i have...

Hi,

first of all thank you for this great library….I just want to be sure that i understood the threading right…

I coded:

with the above combination i am getting compiler warnings:

Hi Paul,

thank you found it :D => Solved

Hi,

i try to read analog values with the analog pins using analogRead. I "only" get 10bit resolution =>0...1023. In the description i read that analog inputs have 13 bit res. => 0...8195...
