Jeff Epler abec199c19 Enable high-quality float hash 
This appears to have a relatively small impact on flash usage but
fixes some pathological slow behavior putting floats in dicts or sets.

Closes: #704

Jeff Epler 9c47fd9c13 Specifically give a better error message for setlabel on RO fs 2018-03-27 21:28:19 -05:00
Jeff Epler fe7f405fc7 Add VfsFat.label property 
These allow accessing the filesystem label.  For instance,
in boot.py, you can set the label on the built-in storage with:
   storage.remount('/', False)
   storage.getmount('/').label = "NEWLABEL"
   storage.remount('/', True)

Users with multiple CIRCUITPY boards may find it desirable to
choose a different label for each board they own.

Scott Shawcroft 37538fc0e7 Fix I2C init hang when the SCL pin is pulled low. 
We added a check to make sure the pins are in a high state before
initing the bus. This leads to a friendly error message when someone
forgets to add the pull up resistors to their circuit.

Jeff Epler c0029e1d97 Don't lose half of the processor's serial number 
Before this change, `microcontroller.cpu.uid` returned values
where the top 4 bits of each byte were zero, because of
an incorrect bitmask used in this function.

Ayke van Laethem fa55b15ac6 extmod/vfs_fat_file: Implement SEEK_CUR for non-zero offset. 
CPython doesn't allow SEEK_CUR with non-zero offset for files in text mode,
and uPy inherited this behaviour for both text and binary files.  It makes
sense to provide full support for SEEK_CUR of binary-mode files in uPy, and
to do this in a minimal way means also allowing to use SEEK_CUR with
non-zero offsets on text-mode files.  That seems to be a fair compromise.

Jeff Epler a7e3c74fed Autocreate files that prevent MacOS indexing of the CIRCUITPYTHON dive 
.. the price of this appears to be about 112 bytes of flash and 12
bytes of RAM, according to the stats printed during the build.

It also uses up 4 directory entries (out of 128), but does not reduce
the number of blocks usable for storing file contents.

These are the same items noted in the Adafruit README for Trinket M0
as preventing MacOS indexing.
