You CAN. It has the huge advantage that it's human readable. You can just print whatever is going over the wire using whatever terminal emulator makes you happy with a couple of wire clips and you can instantly know if the sender sent what you thought and the receiver received that. Don't give that ...

You may find joy in writing the alternative partition table (supported) instead of the primary one.

See https://esp32.com/viewtopic.php?f=19&t=35166 for inspiration and enough hints for working code that you should be able to stick the landing. It worked for me.

the S3 doesn't. Bummer. That's probably the single least awesome aspect of debugging C3 and S3 with the built-in JTAG facility. Every time you load new code to the device, you have to restart the debugger or manually recreate the connection and source all the startup chatter. If that's the way it i...

There's not really enough detail there for anyone to give you a definitive answer. malloc() allocates memory at runtime. There's no static tool that can tell how much memory malloc will use. allocate_foos(int nfoos) { return calloc(sizeof(foo), nfoos); } That might be called with a million and it ma...

IMO, this question has been well answered and the costs actually measured and considered instead of relying on folklore. Gold star. As a reminder, especially to those coming from a background in C, you CAN have multiple values returned from a function. Sometimes that plays out really well and someti...

The search terms you seek are "Semihosting" and "Segger RTT". From the name, you can guess that one company kind of drove the adoption, but it's a simple array of circular queues that allows for separate streams for stdin, stdout, files, console, and more. I've not reviewed these articles in depth a...

Bummer. Depending on what got hooked up wrong and for how long, under what circumstances, etc. (Don't bother trying to explain...it won't matter) the damage can range from one pin that doesn't work (yay) that can just be unused or remapped away in software to damage that basically requires replaceme...

Discord, IMO, is _way_ harder to use to solve actual technical problems. Threading is a total mess so conversations all jumble together and it encourages real-time answers over considered, thought out (tested) answers. It has a place, but I just don't dig it for detailed tech support. I can't parse ...

You're welcome. I totally believe that the default behavior changed. Honestly, I'm more surprised that the old behavior was as it was until approximately now. (In computer science years) The older behavior really is more common in super tiny systems where a difference of a few k can totally blow you...
