I got a micropython repl using HSI not HSE. I found https://community.st.com/thread/28273 asking if he had it right, and used his changes. But it's not right as is. The repl is flaky - it drops characters, and gets error characters at times. So some clock or another isn't right. pyb.freq() reports t...

I've been told that using solder bridges may work for the resistors, in that it'll either work with slightly reduced accuracy, or it'll simply fail to work at all. I'm not up to installing SMD caps, so I'd thought about using the through hole version as you said, but that sounds a bit fragile. The b...

Actually, they give me the specs for the crystal: 8MHz, 16pf, 20ppm.

But also needs 4 SMD parts added to the board - a pair of 20pf caps and a pair of resistors of unknown value. The schematics in the user manual just say "N/A", presumably because they aren't there ;-(.

Thanks.

I'd like to get micropython working on a NUCLE-F411RE with the ST-LINK removed. On current versions the ST-LINK is the source for the HSE clock. Seems there are a number of options to fix this on the board, but the only two that don't clash with my reason for removing the ST-LINK are to buy an appro...

Are you trying to copy the file to the mbed device? That won't work, and gets the space message you are reporting. The mbed storage is on the st-link, not the STM32F, and the file is too big for that. You'll have to use the st-link protocol, which doesn't store the file on the st-link.

Yes, but the documentation didn't answer my question either. That's why I asked.

So the only way to get information about an exception is to parse the traceback and how it doesn't change in the next revision?

First question: do you know if those builds enabled MICROPY_ENABLE_SOURCE_LINE?

And the question I'm actually trying to get answered:

Is there any way to get the line number an exception occurred on in an except: clause?

Is there any way to get the line number an exception occurred on in an except: clause? In CPython, I get it from the traceback returned by sys.exc_info(). I don't see exc_info in micropython's sys, or any way to get the traceback. I did see a define to disable line numbers in the build, so I'm half ...

Yeah, wanting access to that information from Python is the most important issue here. If I could get it without having to include pins_af.py, that would be great. Just out of curiosity, do you know how much bigger pins_af.py is than the dictionary used in those modules? Second is the __str__ method...

I started with this issues on Github, but apparently this needs to be discussed on the forum, so here we go. I posted it as an issue because there's a documented method that doesn't exist. Clearly, a bug in either the objects or the documentation. Further, to me objects that aren't equal but have no...
