Add a command for converting the WAV files to the amp skin tutorial, so that people can use their own files easily.

Should have done it before tagging...

It seems the Mac will happily wipe out at least some of the data on
a freshly reset filesytem, if the filesystem was reset while plugged
into the Mac.

This renders it in yellow/orange box on RTD server.

N (mod 4) is 0..3

Addresses issue #1006.

This is useful if you need precise control over the speed of
peripherals (eg SPI clock).

Erratum in froh.

ReadTheDocs needs the root directory in its search path so it finds
topindex.html.

Also update docs to explain how CAN baudrate is determined.

The sphinx_rtd_theme is used by ReadTheDocs to render a pretty looking
documentation.  If you have this theme installed locally then your
locally-compiled docs will look exactly like the published
documentation.   Otherwise it falls back to the default theme.

Hi,

i would like to add a little clarification to the parameter "data" of i2c.mem_read(): I misunderstood 

        ``data`` can be an integer or a buffer to read into

as "i can give a integer variable to read a integer into" .  This pull-request adds the following clarification:

         ``data`` can be an integer (number of bytes to read) or a buffer to read into

Thanks for your great work!

Best wishes,
Matthias

This needs to be done before actually tagging the new version.
