@davef posted about the WEACT and UART1, and then the post was deleted. The mpconfigboard.h file for the WEACT sets up the REPL to mirror on UART1: https://github.com/mcauser/WEACT_F411CEU6/blob/40061c9ed43dc7fb5e0363f808843ce2cda7e0e1/mpconfigboard.h#L35-L36 You'll want to comment out those 2 lines...

No. This is because there is no USB on the ESP32. It uses an external USB-to-serial chip and there is no way to get MCS through a USB-to-serial chip.

It would be possible to make the RTC callback not have an argument.

I think it takes an argument just because it’s actually an EXTI interrupt and they all take arguments.

What board are you running on?
What version of MicroPython are you using?

If it's coming up with no DFU devices detected, then your device isn't in DFU mode (or you have a bad USB cable). You need to connect BOOT0 needs to be high, and BOOT1 needs to be low, then RESET. That should put your device in DFU mode.

What board are you using?

With timers it makes sense to get the timer object since there may be multiple timers.
With the RTC there is only one, so padding that as an argument doesn’t really help.
It probably makes sense to use whatever is most consistent with the other ports, but currently the RTC is fairly inconsistent.

I think you're right.

It looks like adding this line: into the for loop in the extint_init0 function would fix things.

Sorry I missed the point of that post. It turns out that you can use a UART as a file device with print as well. >>> u = pyb.UART(6, 115200) >>> x = 42 >>> y = 'foo' >>> z = {'a':32} >>> print('x =', x, 'y =', y, 'z =', z, file=u) >>> u.read() b"x = 42 y = foo z = {'a': 32}\n" >>> The above was done...

You can post it here and we can discuss it to see if it's really a bug, or perhaps just a misuse or misunderstanding.

If you're sure it really is a bug, then you create a github issue.

The Pin and PinAF (for the pyboard) are both found in the pin.c file: https://github.com/micropython/micropython/blob/c2317a3a8d5f184de2f816078d91be699274b94e/ports/stm32/pin.c#L592 https://github.com/micropython/micropython/blob/c2317a3a8d5f184de2f816078d91be699274b94e/ports/stm32/pin.c#L669 Curren...
