55f68b3ce8 stmhal, timer: Improve accuracy of freq computation. 2014-10-05 17:52:45 +01:00
Damien George
97ef94df83 stmhal, timer: Set freq from float; get timer source freq. 
Timers now have the following new features:
- can init freq using floating point; eg tim.init(freq=0.1)
- tim.source_freq() added to get freq of timer clock source
- tim.freq() added to get/set freq
- print(tim) now prints freq

24119176e7 stmhal: Allow pyb.freq() function to change SYSCLK frequency. 
Eg pyb.freq(120000000) sets the CPU to 120MHz.  The frequency can be set
at any point in the code, and can be changed as many times as you like.
Note that any active timers will need to be reconfigured after a freq
change.

Valid range is 24MHz to 168MHz (but not all freqs are supported).  The
code maintains a 48MHz clock for the USB at all times and it's possible
to change the frequency at a USB REPL and keep the REPL alive (well,
most of the time it stays, sometimes it resets the USB for some reason).
Note that USB does not work with pyb.freq of 24MHz.

0bbe4de527 stmhal: Update help text. 
Remove reference to pyb.gc; add reference to pyb.millis.

There are lots of functions not listed when you run help(), but it would
be too much to list them all, so we list only some basic, useful ones.

Addresses issue #846.

3a1c4c5bc6 stmhal: Add network and usocket module. 
As per issue #876, the network module is used to configure NICs
(hardware modules) and configure routing.  The usocket module is
supposed to implement the normal Python socket module and selects the
underlying NIC using routing logic.

Right now the routing logic is brain dead: first-initialised,
first-used.  And the routing table is just a list of registered NICs.

cc3k and wiznet5k work, but not at the same time due to C name clashes
(to be fixed).

Note that the usocket module has alias socket, so that one can import
socket and it works as normal.  But you can also override socket with
your own module, using usocket at the backend.

bfa7b480a7 stmhal: For spi_init, add argument to select if NSS pin is enabled. 
Most of the time you don't use the NSS pin of the SPI bus, and so it
shouldn't be enabled by default (this gave some bugs in the past).

8b03d944e2 py: Remove IOError since it's deprecated; use OSError instead. 
In CPython IOError (and EnvironmentError) is deprecated and aliased to
OSError.  All modules that used to raise IOError now raise OSError (or a
derived exception).

In Micro Python we never used IOError (except 1 place, incorrectly) and
so don't need to keep it.

See http://legacy.python.org/dev/peps/pep-3151/ for background.

e9dac3b4d0 py: Add casting to viper; add native mem stores to viper. 
Viper can now do the following:

def store(p:ptr8, c:int):
    p[0] = c

This does a store of c to the memory pointed to by p using a machine
instructions inline in the code.
