Sven Wegener 7ae8e4b679 stmhal: Activate bootloader with pyb.bootloader()
Signed-off-by: Sven Wegener <sven.wegener@stealer.net>
2014-05-18 12:51:21 +02:00
Damien George d6cbbc51ab stmhal: Add time.time() and time.localtime().
time.time: returns seconds since 1/1/2000, as an integer.

time.localtime: Returns 8-tuple: (year, month, date, hour, minute,
    second, weekday, yearday).

Damien George 04b9147e15 Add license header to (almost) all files.
Blanket wide to all .c and .h files.  Some files originating from ST are
difficult to deal with (license wise) so it was left out of those.

Also merged modpyb.h, modos.h, modstm.h and modtime.h in stmhal/.

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 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 764af4b7c5 stmhal: Make DAC dynamically allocate instances; rename dma->write_timed. 2014-04-21 13:06:19 +01:00
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 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.

Damien George d689430e79 stmhal: Add SPI class.
Also some updates to compile with latest changes to core py.

Damien George 3d19137442 stmhal: Add pyb.Pin.init method to re-init GPIO pin mode. 2014-04-19 02:17:57 +01:00
Damien George 6e44381cce stmhal: Improve RTC class; make fatfs use RTC for time stamping files. 2014-04-19 02:17:30 +01:00
Damien George ed5117f6a8 stmhal: Add pyb.unique_id, to get unique id of MCU. 2014-04-19 01:28:18 +01:00
Damien George 44ee42de50 stmhal: Rename pyb.Led to pyb.LED to conform to naming rules.
It's Light Emitting Diode, so should be LED.

Damien George f20e093b9b stmhal: Add lots of constants to stm module. 2014-04-19 00:32:25 +01:00
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 f6be480bda stmhal: Add pyb.have_cdc function to check if USB CDC device is enabled. 2014-04-16 15:52:50 +01:00
Damien George 4d7f4eb6a9 stmhal: Add ADC function to read data at a given frequency.
Reads ADC values into a bytearray (or similar) at a fixed rate.  Needs a
better name and improved API.  Also fix up DAC dma function (which also
needs a better name and API).

Damien George e95da5b784 stmhal: Add I2C.scan method, to scan all devices on the bus.
Simple way to find the address of an attached I2C device.

Damien George 6dba016a56 stmhal: Add pyb.wfi() function (calls __WFI). 2014-04-14 01:45:24 +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 229347139b stmhal: Add functionality to Servo object.
Can now calibrate, set pulse width, angle and speed.

Paul Sokolovsky 72d70cb045 unix, stmhal: Consistently use "FileIO" as class name for file objects.
They correspond to io.FileIO in io module hierarchy (with small caveat
that io.FileIO is raw file and works with bytes, not strings).

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
only (at the moment), so seems a good idea to make the protocol
functions a pointer instead of the actual structure.

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

Paul Sokolovsky 1d4d9ddd9e stmhal: Reimplement file support using stream protocol API.
This adds readline(), readall(), etc. methods. Also other fixes to make
Python API compliant and "with" support.

Damien George 038df43183 stmhal: Implement selector for USB device mode; improve boot up.
Can now choose at boot up whether the USB device is CDC+MSC or CDC+HID.
Choice is made by an option in boot.py, with default being CDC+MSC.
HID+MSC is not currently supported, but should be easy to implement.

Boot up now has ability to change the reset mode: hold down USR switch
while booting and LEDs will count from 1 to 7 to indicate the boot mode.
Release USR when correct mode is selected.  Current modes are 1 (normal
boot), 2 (safe mode), 3 (reset FS mode).
