Ouch. The file I had overlooked . Thanks for the info

Interesting,

However I'm not sure that this portion of code is compiled. I do not see where MICROPY_HW_ENABLE_MDNS_RESPONDER is being defined if at all.

I just tried @pythoncoder's SDCard class. What happens is that: claiming the bus using SPI(1) fails because the HSPI bus is already in use (by the screen). I expected that claiming the bus using SPI(2) or SPI(2, sck=Pin(18), mosi=Pin(23), miso=Pin(19)) freezes the screen. furthermore one gets a "OSE...

The title says it all: what exactly does happen during a soft reset? Looking through the documentation, I only found an explicit reference in the WiPy section: A soft reset simply clears the state of the MicroPython virtual machine, but leaves hardware peripherals unaffected. There are many mentions...

You could use another tool such as

• rshell (https://github.com/dhylands/rshell)
• mpfshell (https://github.com/wendlers/mpfshell)

or even an IDE that connects to microPython:

• Thonny (https://thonny.org)

Thanks.The source code is rather clear. The only thing is that I would not have found it alone: sometimes one can be overwhelmed by the amount of files to search into.

Just an odd question. What happens if one allocates the emergency exception buffer (via alloc_emergency_exception_buf) more than once? Is the memory used for the first allocation lost, reallocated or anything else? I ask this since, as a sloppy programmer, I sometimes use alloc_emergency_exception_b...

What do you mean by garbage? The sample output you give is composed of 13 bytearrays of length 4. When printing them (micro)python only escapes the bytes which do not have ans ascii representation.

Look there: http://docs.micropython.org/en/latest/reference/speed_python.html#the-const-declaration As far as I can tell, when you write foo=const(42) then foo is not a variable but behaves as if, as compile time, it is replaced by 42 . So your code would be seen as: from micropython import const cl...

This could almost become part of a FAQ. There are quite a few questions in the forum on the same issue (amonst them one of mine )
