Yes, you’re correct. Once a connection finishes closing, is aborted, or times out and is closed automatically, the connection is free to be used again. In lwIP lingo, these are called PCB’s. See also:...
To which circular buffer do you refer? Which library or source file?

Hello friends,
I expected to be up in the clouds with the ultimate DIY VA synth, but instead of ascension I fell into the bottomless pit of bandlimited oscillators. Dissatisfied with the dull high-ends and aliasing...

It does look like there is no response but this:

Hi Shawn, sorry but have not checked that response specifically, however I do believe the issue was caused by the circular buffer being corrupted.
I have implemented my own very lightweight circular buffer and the...
U4 is the chip expected to get hot if the 3.3V power is shorted anywhere on the board.
Try measuring the 3.3V power. If you see 3.3V, then looking at chips other than U4 may be worthwhile. But if you get...
Figured out the problem and it's embarrassing: the serial monitor's auto scroll hides the bottom line for some reason. To view that one, you'll have to scroll down.

Sorry, I am distracted as I am trying to debug some of my own not related code.

Hi,
I'm using the Wire library on a Teensy 4.1 with several I2C sensors on a single bus, but the sampling rate is too slow for what I need.
I tried to divide the sensors over 3 separate busses, but the sampling...

I’ll add this note for future readers: the reason it’s only able to accept 8 connections is because the connections are never closed, and because the library is configured by default for up to 8 connections. If there...
Fun fact: the link status is polled approximately 8 times a second in QNEthernet.

That is the normal way the HID parser code works.

Ah, I understand the confusion! Sorry about that. Of course, you have no idea how I started this, the path I took, why or where I want to go.
You got it right, Teensy 4.1 is the server and some PCs are the clients,...
You're only changing the gain on channel 0 of mixer1 and mixer2 ... the playback object is connected to channel 2 of those mixers.

I decided to let Teensy manage RTS. That seems to have fixed the blocking problems and I'll just rearrange things to deal with it that way for now.

There is this Wiki: github.com/TeensyUser/doc/wiki
Perhaps it could be home to such a collection. Not sure if any are covered, there is an 'Electronics' area - but didn't see such topics there now.
Hi Paul.
Thanks for the great work! We use your boards in various applications. It would be really nice if you could show how to use all 16 counter inputs in this project, you said so in the comments "// TODO: can 6...
I have 'fixed' the issue. I took out the statChange checks (which made it so it only prints once per button press), which means the counter goes up or down by thousands per press. This new value will be compared to the...
Then, if you look at the source
bool available() {
if (outputflag == true) {
outputflag = false;
return true;
}
return false;
}
This means that available() will only return true once as it is reset to...

I should have said, "nothing actually processes a connection" because the connections are technically accepted under the covers, it's just that your program does nothing with that information.
Well the 2 pairs of 13 pins tells me the board is likely designed for an original Raspberry Pi (later model Raspberry Pis now have 2 rows of 20 pins, but the first 13 pins are the same pinout as the previous pi models)....
I'm hosting another right now if anyone's interested. I'll be on for the next half hour or so, and longer if anyone joins.

@Richard: What kind of LEDs or interface do you use? Would be cool so see this running in large.
Have you seen this one?

Thanks a lot, a lapsus made me think uncommenting also meant deleting the # symbol :s
It works fine, using it with a TDA1387 after changing the corresponding line on the .cpp file.
I'm having some confusion because on one hand, your test program doesn't accept client connections nor reads from any connected clients (because nothing is connected), but on the other, you describe "all connected...
