bd476acd41 extmod/vfs_fat_file: Allow file obj to respond to ioctl flush request. 2016-12-02 17:26:37 +11:00

e50cb73b7a esp8266: Enable uselect module. 
Select and poll will now work on socket objects.

cb53226b0c extmod/modlwip: Add ioctl method to socket, with poll implementation. 
Implementation of polling may need further fine tuning, but basic
functionality works (tested on esp8266).

2d329c4a56 extmod/moduselect: Use configurable EVENT_POLL_HOOK instead of WFI. 
To make moduselect be usable by any port.

ebc8d730f1 extmod/moduselect: Use stream helper function instead of ad-hoc code. 2016-12-02 16:39:50 +11:00
Damien George
304cfda8c4 py/stream: Move ad-hoc ioctl constants to stream.h and rename them. 
The constants MP_IOCTL_POLL_xxx, which were stmhal-specific, are moved
from stmhal/pybioctl.h (now deleted) to py/stream.h.  And they are renamed
to MP_STREAM_POLL_xxx to be consistent with other such constants.

All uses of these constants have been updated.

f7545b200e stmhal/moduos: Implement POSIX behaviour of rename, allow to overwrite. 2016-12-02 15:13:29 +11:00

b7df3e541a extmod/vfs_fat: Implement POSIX behaviour of rename, allow to overwrite. 
If the destination of os.rename() exists then it will be overwritten if it
is a file.  This is the POSIX behaviour, which is also the CPython
behaviour, and so we follow suit.

See issue #2598 for discussion.

08bd7d1d31 stmhal/sdcard: Clean/invalidate cache before DMA transfers with SD card. 
Add 2 macros in mphalport.h that clean and invalidate data caches only on
STM32F7 MCUs.  They are needed to ensure the cache coherency before/after
DMA transferts.

* MP_HAL_CLEANINVALIDATE_DCACHE cleans and invalidate the data cache. It
  must be called before starting a DMA transfer from the peripheral to the
  RAM memory.

* MP_HAL_CLEAN_DCACHE cleans the data cache.  It must be called before
  starting a DMA transfert from the RAM memory to the peripheral.

These macros are called in sdcard.c, before reading from and writing to
the SDCard, when DMA is used.

a081b49d55 extmod/modframebuf: Optimise fill and fill_rect methods. 
Fill is a very common operation (eg to clear the screen) and it is worth
optimising it, by providing a specialised fill_rect function for each
framebuffer format.

This patch improved the speed of fill by 10 times for a 16-bit display
with 160*128 pixels.

81e171b7bb extmod/modframebuf: Add back legacy FrameBuffer1 "class". 
For backwards compatibility.  It simple creates a frame buffer with the
MVLSB format.

eb09336e99 drivers/display/ssd1306.py: Update to use FrameBuffer not FrameBuffer1 2016-12-01 16:43:25 +11:00
Radomir Dopieralski
225e22b287 extmod/modframebuf: Make FrameBuffer handle 16bit depth. 
Rename FrameBuffer1 into FrameBuffer and make it handle different bit
depths via a method table that has getpixel and setpixel.  Currently
supported formats are MVLSB (monochrome, vertical, LSB) and RGB565.

Also add blit() and fill_rect() methods.

c19a395cac stmhal/adc: Make channel "16" always map to the temperature sensor. 
The temperature sensor on F4 and F7 MCUs is mostly, but not always, on
channel 16.  To retain compatibility across all these MCUs this patch
maps the user-facing channel 16 to the internal temperature sensor.

52dfad0879 stmhal/adc: Add ADCAll.read_vref method, returning "3.3v" value. 2016-11-30 12:58:54 +11:00
Damien George
e72353cc48 stmhal/adc: Make ADCAll.read_core_temp return accurate float value. 
It now uses factory calibration values to get a more accurate value, and
returns a float instead of an integer.
 2016-11-30 12:58:53 +11:00
Damien George
87215a0f04 stmhal/adc: Provide more accurate measure of VBAT and VREFINT. 
By using factory calibration values.

a6de451a13 zephyr: Add .gitignore to ignore Zephyr's "outdir" directory. 
That's where Zephyr keeps object files and produced executables.

029f215ead stmhal/adc: Add "mask" selection parameter to pyb.ADCAll constructor. 
The "mask" parameter is used to select which pins the ADCAll constructor
will initialise to analog mode.  It defaults to all pins (0xffffffff),
which is backwards compatible with previous behaviour.

0d75b0d962 stmhal: Add address parameters to openocd config files.

139b891d6d stmhal: Add back GPIO_BSRRL and GPIO_BSRRH constants to stm module. 
These were inadvertently removed with a recent upgrade to CMSIS, where
those registers were no longer defined in the CMSIS headers, and hence
no longer extracted.

e6cf5fb2cc py/compile: Remove comment about TODO for short circuiting for if-stmt. 
Short circuiting is handled correctly by c_if_cond, and constants within
short-circuit expressions are optimised by the parser.

a31a3a9fd5 tests/basics: Add test for dict.fromkeys where arg is a generator. 
Improves coverage because it tests the case where the arg does not have a
__len__ slot.

f8b71aabb4 stmhal/machine_i2c: Provide HW implementation of I2C peripherals for F4. 
With this patch machine.I2C() uses HW I2C peripheral blocks on F4 MCUs.
Software I2C is used for other MCUs.

3053748987 stmhal: Add beginnings of port-specific machine.I2C implementation. 
This allows one to construct an I2C object using ids that are specific
to the stmhal port, eg machine.I2C('X').  Right now the implementation
of I2C uses software I2C but the idea is to just change the C-level I2C
protocol functions to hardware implementations later on.

5d2279bec1 extmod/machine_i2c: Add hook to constructor to call port-specific code. 
If MICROPY_PY_MACHINE_I2C_MAKE_NEW is defined then it is called when an
I2C object is constructed with an id which is not -1.
