Damien George bad2df3e95 stmhal, modwiznet5k: Add very minimal documentation. 2014-09-01 22:58:22 +01:00
Damien George bcf041f1a3 stmhal: Add wiznet5k module, to control WIZnet ethernet adaptor.
Allows to create socket objects that support TCP and UDP in server and
client mode.  Interface is very close to standard Python socket class,
except bind and accept do not work the same (due to hardware not
supporting them in the usual way).

Not compiled by default.  To compile this module, use:
make MICROPY_PY_WIZNET5K=1

Damien George ecc88e949c Change some parts of the core API to use mp_uint_t instead of uint/int.
Addressing issue #50, still some way to go yet.

Damien George 8707ea3421 lib: Add lib and libm, moving current files from stmhal.
Top-level lib directory is for standard C libraries that we want to
provide our own versions of (for efficiency and stand-alone reasons).
It currently has libm in it for math functions.

Also add atanf and atan2f, which addresses issue #837.

Dave Hylands 994bb4a839 Fix sdcard_power_on to not do anything if the card is already powered on. 2014-08-25 10:16:52 -07:00
Damien George 34e43c7ee9 stmhal: Improve efficiency of SysTick IRQ and HAL_Delay.
SysTick IRQ now increases millisecond counter directly (ie without
calling HAL_IncTick).  Provide our own version of HAL_Delay that does a
wfi while waiting.  This more than halves power consumption when running
a loop containing a pyb.delay call.  It used to be like this, but new
version of HAL library regressed this feature.

Damien George 29c92a407c stmhal: Use MP_OBJ_NEW_SMALL_INT directly in pyb.micros/millis.
Also some whitespace cleanup.
2014-08-25 17:38:55 +01:00
Dave Hylands 2bf044442e Add support for pyb.micros() by using the systick timer.
I also removed trailing spaces from modpyb.c which affected a couple
of lines technically not part of this patch.

Tested using: https://github.com/dhylands/upy-examples/blob/master/micros_test.py

which eventually fails due to wraparound issues (I could fix the test to compensate
but didn't bother)

Damien George e5cbb70328 stmhal: Make enable_irq and disable_irq inline functions.
These functions are generally 1 machine instruction, and are used in
critical code, so makes sense to have them inline.

Also leave these functions uninverted (ie 0 means enable, 1 means
disable) and provide macro constants if you really need to distinguish
the states.  This makes for smaller code as well (combined with
inlining).

Applied to teensy port as well.

Dave Hylands 9480138f0c Add save/restore_irq
Factored irq functions into a separate file.

Damien George 8ba832456e stmhal, modtime: Small changes, reduced code size by around 80 bytes.
Also added test for modtime.
2014-08-24 17:40:24 +01:00
Dave Hylands 6678595e7e Add time.mktime and enhance time.localtime (for stmhal)
Now you can use time.localtime on the timestamps presented by os.stat

Damien George 3c658a4e75 py: Fix bug where GC collected native/viper/asm function data.
Because (for Thumb) a function pointer has the LSB set, pointers to
dynamic functions in RAM (eg native, viper or asm functions) were not
being traced by the GC.  This patch is a comprehensive fix for this.

Addresses issue #820.

Dave Hylands 3688414d9d Put some code into the first 16K of flash
This basically shrinks the remaining size of flash in the portion
that goes after the internal flash drive.

Damien George b63be37be1 stmhal: In safe mode, still mount SD card and present as MSD over USB.
It's still "safe" because no scripts are run.  Remove the SD card if you
want to access the internal flash filesystem.  Addresses issue #616.

Also: remove obsolete pyb.source_dir setting, and reset pyb.main and
pyb.usb_mode settings on soft-reset.

Damien George 244476e3e6 stmhal: For non-debug compile, enable CC/LD opt to remove dead code.
Saves over 35k ROM due to elimination of unused HAL functions.  All
tests pass.

Addresses issue #702.

Damien George 284efa89ae stmhal/teensy: Use _ instead of - in source file names.
Trying to move towards consistency, let's use _ exclusively in names of
source files (eg .c, .h, .csv).

Damien George 5b7c0c437b stmhal: Comment out unused functions. 2014-08-08 22:25:46 +01:00
Dave Hylands 6f418fc1b0 Add support for selecting pin alternate functions from python.
Converts generted pins to use qstrs instead of string pointers.

This patch also adds the following functions:
pyb.Pin.names()
pyb.Pin.af_list()
pyb.Pin.gpio()

dir(pyb.Pin.board) and dir(pyb.Pin.cpu) also produce useful results.

pyb.Pin now takes kw args.

pyb.Pin.__str__ now prints more useful information about the pin
configuration.

I found the following functions in my boot.py to be useful:
```python
def pins():
    for pin_name in dir(pyb.Pin.board):
        pin = pyb.Pin(pin_name)
        print('{:10s} {:s}'.format(pin_name, str(pin)))

def af():
    for pin_name in dir(pyb.Pin.board):
        pin = pyb.Pin(pin_name)
        print('{:10s} {:s}'.format(pin_name, str(pin.af_list())))
```

Damien George 3ef911345c stmhal: Update STM32Cube F4 HAL driver to V1.3.0.
This patch updates ST's HAL to the latest version, V1.3.0, dated 19 June
2014.  Files were copied verbatim from the ST package.  Only change was
to suppress compiler warning of unused variables in 4 places.

A lot of the changes from ST are cosmetic: comments and white space.
Some small code changes here and there, and addition of F411 header.

Main code change is how SysTick interrupt is set: it now has a
configuration variable to set the priority, so we no longer need to work
around this (originall in system_stm32f4xx.c).

Damien George ccacdf44b6 stmhal: Clean up reset/soft-reset code; fix bug init'ing VCP exc.
Make a clearer distinction between init functions that must be done
before any scripts can run (xxx_init0) and those that can be safely
deferred (xxx_init).

Fix bug initialising USB VCP exception.  Addresses issue #788.

Re-order some init function to improve reliability of
reset/soft-reset.
2014-08-04 11:09:51 +01:00
Damien George 8dbbbbc793 Put call to qstr_init and mp_init_emergency_exc_buf in mp_init.
qstr_init is always called exactly before mp_init, so makes sense to
just have mp_init call it.  Similarly with
mp_init_emergency_exception_buf.  Doing this makes the ports simpler and
less error prone (ie they can no longer forget to call these).
