Damien George 8d09640b22 stmhal: Add documentation in comments, and script to generate HTML.
Decided to write own script to pull documentation from comments in C code.
Style for writing auto generated documentation is: start line with ///
and then use standard markdown to write the comment.  Keywords
recognised by the scraper begin with backslash.  See code for examples.

Running: python gendoc.py modpyb.c accel.c adc.c dac.c extint.c i2c.c
led.c pin.c rng.c servo.c spi.c uart.c usrsw.c, will generate a HTML
structure in gendoc-out/.

gendoc.py is crude but functional.  Needed something quick, and this was
it.

Damien George 46e1f26615 stmhal, usrsw: Update comments for new switch API. 2014-04-21 18:28:23 +01:00
Damien George 6125ba4a7f stmhal: Make switch a class, to follow suit of all other modules.
Instead of pyb.switch() as a function, it's more consistent (with
respect to all the other modules and peripherals) to have
pyb.Switch() create a switch object.  This then generalises to having
multiple switches.  Call the object to get its state.  Use sw.callback
to set the callback function for when the switch is pressed.

Damien George af797f476f stmhal, servo: Rename calibrate method to calibration.
It should be a noun, since it supports getting and setting depending on
the number of arguments given.

Damien George 6691c9e655 stmhal, timer: Remove obsolete global variable. 2014-04-21 18:19:50 +01:00
Damien George 7fdfa93700 stmhal: Add Timer class: simple TIM control, incl callback on IRQ.
Simple but functional timer control.  More sophistication will
eventually be added, or for now just use direct register access :)

Also added pyb.freq() function to get MCU clock frequencies.

Damien George 7533700393 stmhal: Rename USART to UART.
It's really a UART because there is no external clock line (and hence no
synchronous ability, at least in the implementation of this module).
USART should be reserved for a module that has "S"ynchronous capabilities.

Also, UART is shorter and easier to type :)

Damien George 34f01c2ca1 stmhal: Add some documentation to I2C, SPI and USART modules. 2014-04-21 01:59:43 +01:00
Damien George 3771a097da stmhal: Improve USART class, to be more like SPI and I2C.
The three classes I2C, SPI and USART now have a fairly uniform (Python)
API.  All are constructed, initialised and deinitialised in the same
way.  They can have most of their parameters set, using keyword arguments.
All have send and recv (although slightly different with I2C requiring an
address in master mode).  recv can do inplace receiving (ie store the
data in a previously-created bytearray).

It's just polling mode at the moment, but interrupt and DMA would be
nice to add.

The HAL handles for the I2C/SPI objects are rather large, so we don't

Damien George 38ae014e42 stmhal: Update ADC, DAC and I2C objects to use new buffer protocol.
Main reason for expanding buffer protocol API was to support writes to a
buffer in ADC module (see read_timed).  With this change you can now
create an array of arbitrary type and ADC.read_timed will store into
that array in the correct format (byte, int, float).  I wonder though if
all these changes were really worth it to support just this function.
Hopefully this enhanced buffer protocol API (with typecode specified)
will be used elsewhere.

Damien George a8f5d15fc6 stmhal: Update help and comments re gpio changing to Pin. 2014-04-18 22:48:59 +01:00
Damien George c66d86c5ce stmhal: Big cleanup; merge gpio into Pin; make names consistent.
This is an attempt to clean up the Micro Python API on the pyboard.
Gpio functionality is now in the Pin object, which seems more natural.
Constants for MODE and PULL are now in pyb.Pin.  Names of some
classes have been adjusted to conform to CamelCase.  Other
miscellaneous changes and clean up here and there.

Damien George 5b65f0c7d3 py: Rename USE_COMPUTED_GOTOS to USE_COMPUTED_GOTO and enable on stmhal.
On stmhal, computed gotos make the binary about 1k bigger, but makes it
run faster, and we have the room, so why not.  All tests pass on
pyboard using computed gotos.

Damien George efc22e376f stmhal: Fix 64-byte USB packet bug properly.
A 64-byte packet is now followed by a 0-byte packet if there is nothing
more to send.  This flushes the USB endpoint.

Damien George 6d983539bc stmhal: Improve flash storage cache management.
Internal flash used for the filesystem is now written (from the cache)
only after a 5s delay, or when a file is closed, or when the drive is
unmounted from the host.  This delay means that multiple writes can
accumulate in the cache, and leads to less writes to the flash, making
it last longer.

It's implemented by a high-priority interrupt that takes care of flash
erase and write, and flushing the cache.

This is still only an interim solution for the flash filesystem.  It
eventually needs to be replaced with something that uses less RAM for
the cache, something that can use more of the flash, and something that
does proper wear levelling.

Andrew Scheller 70a7d7a943 build directory can now be renamed
The autogenerated header files have been moved about, and an extra

Also tidied up the way the different Makefiles build their include-
directory flags

Damien George 9699ea6a2f stmhal: Fix USB MSC so that it unmounts correctly on Mac OS X.
Mac OS X sends a SCSI command to remove the medium when it unmounts a
drive.  If this command is not honoured, then OS X will automatically
remount the drive, making it impossible to eject.  This patch disables
the USB MSC when the right SCSI command is sent.

Damien George 4d7f4eb6a9 stmhal: Add ADC function to read data at a given frequency.

Tweak pybcdc.inf to match recent changes to pybcdc.h
2014-04-10 22:51:48 +01:00
Damien George 3f4898456b stmhal: Add stm module, which contains some constants for the MCU.
Also contains raw memory read/write functions, read8, read16, read32,
write8, write16, write32.  Can now do:

stm.write16(stm.GPIOA + stm.GPIO_BSRRL, 1 << 13)

This turns on the red LED.

With the new constant folding, the above constants for the GPIO address
are actually compiled to constants (and the addition done) at compile
time.  For viper code and inline assembler, this optimisation will make
a big difference.  In the inline assembler, using these constants would
not be possible without this constant folding.

Damien George 97790455fe Improve REPL detecting when input needs to continue.
Full CPython compatibility with this requires actually parsing the

having compatibility at this level does not hurt the goals of Micro
Python.

Damien George 27e735fd18 py: Replace stream_p with *stream_p in mp_obj_type_t.
This is to reduce ROM usage.  stream_p is used in file and socket types

functions a pointer instead of the actual structure.

It saves 308 bytes of ROM in the stmhal/ port, 928 in unix/.

Damien George 7efc5b3f34 py: Make globals and locals proper dictionary objects.
Finishes addressing issue #424.

In the end this was a very neat refactor that now makes things a lot

simplifications in certain places, now that everything is a dict object.

Also converted builtins tables to dictionaries.  This will be useful
when we need to turn builtins into a proper module.
