They were writing an article for school on the health benefits of a pESCatarian diet.
A bit of confusion had them think ESC should be typed as a single unit with a single key.
This was never going well no matter where the key had been located.

During a demo using pretty much the latest technologies, I once got the feedback "This new software feels like we're going back to the 80's! We've got touch screens now and we're going back to mouses?!"
"No, you'll get touch screens, but we didn't have one available for this demo."
"Oh, well in that case it looks really neat!"
Mouses are so 80's

Boot one core.
Using that core, inject code for the second core into memory, and then cajole the 2nd core into executing it.
Enable a message passing system between the cores.
I have 128KB to implement the main logic of this app on the 2nd core, because the rest of the memory is devoted to visualizations on the primary core. and the 2nd core has to expose a composite USB device.
128KB

Are you using C for all this stuff ? I'd like to see the code/workflow

Yeah, just straight C. I didn't want to deal with getting NXP's toolchain to host C++ libs and stuff. I know it can, but LVGL is C anyway.
I'm under NDA so I can't really share much. This is all R&D for a work project, but the code flow is actually pretty simple. The workflow is basically using MCUxpresso IDE.
It's all cooperatively threaded, with the exception of the core to core interaction, which is handled by an ersatz mutex and a simple message passing scheme based on shared memory.
The M7 runs in a simple master loop, processing a bunch of visualization data and sending it out to the LCD panels.
The M4 handles core logic of the app, and communication with the outside world via USB HID.
The M7 basically is a visualization engine. The M4 tells it what to display and the M7 displays it.
Despite the M7 being logically slaved to the master in terms of flow, it's actually technically the master, in that it's the one that boots initially and kicks everything off. The reason is that its part of the whole mess requires the most memory and flash resources, so to me it made sense to package the smaller payload (the M4 code) and inject *that* into memory, if that makes sense.

Na, this [^] can be done with only 64kb (... and a bit of hw acceleration ... ), so 128kB should be more than enough

A few days ago, Code Witch expressed a rather low opinion of the Eclipse IDE. And someone commented that they think Visual Studio is very good.
Well I can say that I'm liking Visual Studio because I just moved a file from one folder to another by dragging it, and upon dropping the file, it asked me if I wanted it to adjust the namespaces for the classes inside the file!
Nothing could have been more appropriate or helpful at the time.
Viva La Visual Studio!
The difficult we do right away...
...the impossible takes slightly longer.
