Hi,

If the stack or malloc heap in Teensy 4.x grows too large for the space available, how will I know? I'm starting to suspect out-of-memory errors in some strange crashes I'm seeing. Is there...

Does anyone happen to have a windows executable for teensy_loader_cli, the Teensy Loader Command Line Interface, that is recent enough to work with Teensy 4.1? I am quite unfamiliar with gcc...

Based on this quote, I'd think you'd agree that the conditional of the second if statement has a mistake and should be _socket_num instead of socket_num?



(P.S. Thanks for the contribution of...

I think you're right about the history of the code. But it feels like perhaps the intent was to do limit-checking on the input parameter to the function, and so this is a typo? Perhaps such...

Hi, I was looking through NativeEthernet.cpp and found this function:

void EthernetClass::setSocketNum(uint8_t _socket_num){
if(socket_num != 0) return;
if(socket_num >...

Thank you!!! I will try that. If I can't always prevent the overflow, once the ring buffer is full, is there some special step I have to do to get it un-stuck and back into normal operation (do I...

I have studied the problem a bit more, and suspect that it occurs under conditions where the Teensy is flooded with incoming packets right at the moment of startup. My working theory (perhaps...

Hello, there is a bit of code inside the teensy41_ethernet.ino sketch which is:

if (!(ENET_RDAR & ENET_RDAR_RDAR)) {
print("receiver not active\n");
}


I have been finding that under...

Is there any pre-existing library to allow a Teensy 3.x or 4.x to access a secure HTTPS web site through ethernet? Seems like nowadays that people have seen that IOTs can become dangerous botnets,...

Just gave this a try; using the USBHost_t36 on the second port of a Teensy 3.6, all the USB mice I have work perfectly, including the Teensy-based mouse and also a MKRZERO-based mouse, (both of which...

Thank you both for your guidance. Pointed by you in the correct direction to meander, I think I am coming to an improved understanding. As I understand it, a USB mouse may operate in two different...

Since it appears the error occurs in the CircuitsAtHome code, I would think this issue could be duplicated by using a Teensy USB host shield and then plugging a Teensy LC or Teensy 3.6 HID device...

A bit of a surprise, but I have a Teensy 3.6-based mouse (i.e. USB HID device) which works fine on windows machines. I also have an Arduino Due-based USB host, which is running the Arduino-official...

Aha! Yes, I see now that the SGTL5000 requires a 1.8V supply on pin 30 for its inner digital circuitry, but the digital interfacing is all conducted at 3.3V. Very straightforward. Thank you!

Hi, I noticed there is a 1.8V regulator on the audio shield. https://www.pjrc.com/store/teensy3_audio.html

This unnerves me because I don't understand why it's necessary. It appears to suggest...

Thank you!! I am still waiting for hardware, but I will check this out and update later. Much appreciated!

Hi, I was intending to use the audio shield for DAC and ADC functionality in a commercial project where I plug the Teensy3.6 into a custom PCB; I will probably still do this for the experience. ...
