6e80f0ee90 stmhal/modules: Provide sym-link to onewire.py driver. 2017-06-22 16:36:04 +10:00

b19138e82e stmhal: Make available the _onewire module, for low-level bus control. 2017-06-22 16:20:22 +10:00

8ed7155828 stmhal: Add "quiet timing" enter/exit functions.
They disable all interrupts except for SysTick and are useful for doing
certain low-level timing operations.

4f9858e86d stmhal: Move pybstdio.c to lib/utils/sys_stdio_mphal.c for common use.
It provides sys.stdin, sys.stdout, sys.stderr for bare-metal targets based
on mp_hal functions.

fd860dc552 stmhal: Add .value() method to Switch object, to mirror Pin and Signal. 2017-06-15 17:34:51 +10:00

4abe3731e3 stmhal: Add initial implementation of Pin.irq() method.
This method follows the new HW API and allows to set a hard or soft IRQ
callback when a Pin has a level change.  It still remains to make this
method return a IRQ object.

c064f0a36a stmhal/mpconfigport.h: Remove config of PY_THREAD_GIL to use default.
The default for the GIL is to enable it if threading is enabled, and this
is the recommended way to use threading with the stmhal port.

22cedef95f stmhal/usbdev: For MSC implement SCSI SYNCHRONIZE_CACHE command.
Currently just a dummy command that returns "success", but it's needed for
some O/S's to correctly talk with the SCSI layer.

bcf31a3908 esp8266, stmhal, zephyr: Rename machine.Pin high/low methods to on/off.
For consistent Pin/Signal class hierarchy. With it, Signal is a proper
(while still ducktyped) subclass of a Pin, and any (direct) usage of Pin
can be replace with Signal.

As stmhal's class is reused both as machine.Pin and legacy pyb.Pin,
high/low methods actually retained there.

37bd3b4f4c stmhal/modmachine: Add machine.UART class, linking to pyb.UART.
pyb.UART has a superset of machine.UART functionality so can be used to
provide compatibility with other ports that also implement machine.UART.

49de9b68d2 qemu-arm, stmhal: Remove dummy memory.h since it's no longer needed.
extmod/crypto-algorithms/sha256.c was recently fixed so that it didn't
include this header.

03053f82db mpy-cross, unix, windows, stmhal: Enable return-if-else optimisation.
Prior to making this a config option it was previously available on these
(and all other) ports, and it makes sense to keep it enabled for mpy-cross
as well as ports that have a decent amount of space for the code.

1f3887dc28 stmhal/timer: Clear interrupt flag before setting callback.
Sometimes when setting a channel callback the callback fires immediately,
even if the compare register is set to a value far into the future. This
happens when the free running counter has previously been equal to what
happens to be in the compare register.

This patch make sure that there is no pending interrupt when setting a
callback.

3b447ede78 stmhal/usbd_cdc_interface: Change CDC RX to use a circular buffer.
This should be a little more efficient (since we anyway scan the input
packet for the interrupt char), and it should also fix any non-atomic read
issues with the buffer state being changed during an interrupt.

Throughput tests show that RX rate is unchanged by this patch.

9a8e7f7a8e stmhal/usbd_cdc_interface: Increase in-endpoint timeout to 500ms.
The previous timeout value of 150ms could lead to data being lost (ie never
received by the host) in some rare cases, eg when the host is under load.
A value of 500ms is quite conservative and allows the host plenty of time
to read our data.

4c307bfba1 all: Move BYTES_PER_WORD definition from ports to py/mpconfig.h
It can still be overwritten by a port in mpconfigport.h but for almost
all cases one can use the provided default.

b6c7e4b143 all: Use full path name when including mp-readline/timeutils/netutils.
This follows the pattern of how all other headers are now included, and
makes it explicit where the header file comes from.  This patch also
removes -I options from Makefile's that specify the mp-readline/timeutils/
netutils directories, which are no longer needed.

2460888c74 stmhal/i2c: Clean the cache so that I2C DMA works on F7 MCUs. 2017-03-31 12:56:18 +11:00

aa7de3ff67 stmhal: Move L4/F7 I2C timing constants from mpconfigboard.h to i2c.c.
Such constants are MCU specific so shouldn't be specified in the board
config file (else it leads to too much duplication of code).

This patch also adds I2C timing values for the F767/F769 for 100k, 400k
and 1MHz I2C bus frequencies.

7876e54aa5 stmhal/sdcard: Add support for SDMMC2 on F7 MCUs.
By default the SDIO (F4) or SDMMC1 (L4, F7) is used as the SD card
peripheral, but if a board config defines MICROPY_HW_SDMMC2_CK and other
pins then the SD card driver will use SDMMC2.

22e2f4a0e8 stmhal/spi: Increase SPI transfer timeout, proportional to num bytes.
With the existing timeout of 100ms the transfer would end prematurely if
the baudrate was low and the number of bytes to send was high.  This patch
fixes the problem by making the timeout proportional to the number of bytes
that are being transferred.

e997bb6328 stmhal/hal: For F7 MCUs, expose DMA_CalcBaseAndBitshift function.
It's needed by the DMA driver to do an efficient reinitialisation.  This
patch follows what is done in the F4 HAL.

ff927cb106 stmhal/spi: Clean and/or invalidate D-cache before SPI DMA transfers.
On MCUs with a cache (eg F7) this must be done or else the SPI data that is
transferred is incorrect.

125eae1ba3 py/modbuiltins: For round() builtin use nearbyint instead of round.
The C nearbyint function has exactly the semantics that Python's round()
requires, whereas C's round() requires extra steps to handle rounding of
numbers half way between integers.  So using nearbyint reduces code size
and potentially eliminates any source of errors in the handling of half-way
numbers.

Also, bare-metal implementations of nearbyint can be more efficient than
round, so further code size is saved (and efficiency improved).

nearbyint is provided in the C99 standard so it should be available on all
supported platforms.

75589272ef all/Makefile: Remove -ansi from GCC flags, its ignored anyway.
The -ansi flag is used for C dialect selection and it is equivalent to -std=c90.
Because it goes right before -std=gnu99 it is ignored as for conflicting flags
GCC always uses the last one.

96c35d0ac4 stmhal/pybthread: Allow interrupts to work during lock/unlock of mutex.
When locking/unlocking a mutex we only need to protect against a thread
switch, not general interrupts.
