Damien George 48e9262f55 py/dynruntime: Implement uint new/get, mp_obj_len and mp_obj_subscr. 2019-12-13 13:29:11 +11:00
Damien George c2eaf56634 stm32/Makefile: Enable max buffer size on W5200 NIC when used with lwIP.
Because in network_wiznet5k the TX/RX buffers are set to 16k each when in
MACRAW mode, which is used with lwIP.

Damien George cd9de63c0e drivers/wiznet5k: Allow selecting maximum fixed buffer size for MACRAW.
Enabling WIZCHIP_USE_MAX_BUFFER will make the TX/RX buffers the maximum
available size, for use with MACRAW mode.

Damien George abc642973d py/dynruntime: Add support for float API to make/get floats.
We don't want to add a feature flag to .mpy files that indicate float
support because it will get complex and difficult to use.  Instead the .mpy
is built using whatever precision it chooses (float or double) and the
native glue API will convert between this choice and what the host runtime
actually uses.

Damien George aad79adab7 tools/mpy_ld.py: Add new mpy_ld.py tool and associated build files.
This commit adds a new tool called mpy_ld.py which is essentially a linker
that builds .mpy files directly from .o files.  A new header file
(dynruntime.h) and makefile fragment (dynruntime.mk) are also included
which allow building .mpy files from C source code.  Such .mpy files can
then be dynamically imported as though they were a normal Python module,
even though they are implemented in C.

Converting .o files directly (rather than pre-linked .elf files) allows the
resulting .mpy to be more efficient because it has more control over the
relocations; for example it can skip PLT indirection.  Doing it this way
also allows supporting more architectures, such as Xtensa which has
specific needs for position-independent code and the GOT.

The tool supports targets of x86, x86-64, ARM Thumb and Xtensa (windowed
and non-windowed).  BSS, text and rodata sections are supported, with
relocations to all internal sections and symbols, as well as relocations to
some external symbols (defined by dynruntime.h), and linking of qstrs.

Damien George 27879844d2 tools/mpy-tool.py: Add ability to merge multiple .mpy files into one.
Usage:

    mpy-tool.py -o merged.mpy --merge mod1.mpy mod2.mpy

The constituent .mpy files are executed sequentially when the merged file
is imported, and they all use the same global namespace.

Damien George 360d972c16 py/nativeglue: Add new header file with native function table typedef. 2019-12-12 20:15:28 +11:00
Damien George b47e155bd0 py/persistentcode: Add ability to relocate loaded native code.
Implements text, rodata and bss generalised relocations, as well as generic
qstr-object linking.  This allows importing dynamic native modules on all
supported architectures in a unified way.

Damien George 84958a8fe1 extmod/modbluetooth: Allow setting ringbuf size via BLE.config(rxbuf=).
The size of the event ringbuf was previously fixed to compile-time config
value, but it's necessary to sometimes increase this for applications that
have large characteristic buffers to read, or many events at once.

With this commit the size can be set via BLE.config(rxbuf=512), for
example.  This also resizes the internal event data buffer which sets the
maximum size of incoming data passed to the event handler.

Damien George 7aeafe2ae9 extmod/modbluetooth: Add optional 4th arg to gattc_write for write mode.
This allows the user to explicitly select the behaviour of the write to the
remote peripheral.  This is needed for peripherals that have
characteristics with WRITE_NO_RESPONSE set (instead of normal WRITE).  The
function's signature is now:

    BLE.gattc_write(conn_handle, value_handle, data, mode=0)

mode=0 means write without response, while mode=1 means write with
response.  The latter was the original behaviour so this commit is a change
in behaviour of this method, and one should specify 1 as the 4th argument
to get back the old behaviour.

In the future there could be more modes supported, such as long writes.

Damien George 40cc7ec677 stm32/mpconfigport.h: Use IRQ_PRI_PENDSV to protect bluetooth ringbuf.
The default protection for the BLE ringbuf is to use
MICROPY_BEGIN_ATOMIC_SECTION, which disables all interrupts. On stm32 it
only needs to disable the lowest priority IRQ, pendsv, because that's the
IRQ level at which the BLE stack is driven.

Damien George 8ce69288e9 extmod/modbluetooth: Remove limit on data coming from gattc data input.
This removes the limit on data coming in from a BLE.gattc_read() request,
or a notify with payload (coming in to a central).  In both cases the data
coming in to the BLE callback is now limited only by the available data in
the ringbuf, whereas before it was capped at (default hard coded) 20 bytes.

Damien George d6e051082a extmod/modbluetooth: Simplify how BLE IRQ callback is scheduled.
Instead of enqueue_irq() inspecting the ringbuf to decide whether to
schedule the IRQ callback (if ringbuf is empty), maintain a flag that knows
if the callback is on the schedule queue or not.  This saves about 150
bytes of code (for stm32 builds), and simplifies all uses of enqueue_irq()
and schedule_ringbuf().

Damien George 77b8f86a5e stm32/qstrdefsport.h: Remove unused qstrs and make USB ones conditional.
qstrs in this file are always included in all builds, even if not used
anywhere.  So remove those that are never needed, and make USB names
conditional on having USB enabled.
