Dave Hylands 11115e4d23 stmhal: Add I2S support to make-pins.py 2015-07-07 10:15:37 +01:00
Damien George 0807139c1d stmhal: Add config option for storage to use second flash segment.
When enabled this allows the internal storage to be split over 2
contiguous regions of flash (two segments), and so the storage can be
increased.

This option is disabled by default, giving original behaviour.

blmorris c5175526dd stmhal/dma.c: Modify dma_init() to accept init struct as an argument
This removes hard-coded DMA init params from dma_init(), instead defining
these parameters in a DMA_InitTypeDef struct that gets passed as an
argument to dma_init()
This makes dma_init more generic so it can be used for I2S and SD Card,
which require different initialization parameters.

Damien George 0aa5e75000 stmhal: Break immediately from USB CDC busy wait loop if IRQs disabled.
If IRQs are disabled then the USB CDC buffer will never be
drained/filled and the sys-tick timer will never increase, so we should
not busy wait in this case.

To build:

make BOARD=ESPRUINO_PICO

To deploy: short the BOOT0/BTN contact on the back of the board (eg by
drawing over it with a graphite pencil), then hold down BTN while
inserting the board into the USB port.  The board should then enter DFU
mode, and the firmware can be downloaded using:

make BOARD=ESPRUINO_PICO deploy

Damien George 7f9d1d6ab9 py: Overhaul and simplify printf/pfenv mechanism.
Previous to this patch the printing mechanism was a bit of a tangled
mess.  This patch attempts to consolidate printing into one interface.

All (non-debug) printing now uses the mp_print* family of functions,
mainly mp_printf.  All these functions take an mp_print_t structure as
their first argument, and this structure defines the printing backend
through the "print_strn" function of said structure.

Printing from the uPy core can reach the platform-defined print code via
two paths: either through mp_sys_stdout_obj (defined pert port) in
conjunction with mp_stream_write; or through the mp_plat_print structure
which uses the MP_PLAT_PRINT_STRN macro to define how string are printed
on the platform.  The former is only used when MICROPY_PY_IO is defined.

With this new scheme printing is generally more efficient (less layers
to go through, less arguments to pass), and, given an mp_print_t*
structure, one can call mp_print_str for efficiency instead of
mp_printf("%s", ...).  Code size is also reduced by around 200 bytes on
Thumb2 archs.

Damien George b1f68685ec stmhal: In USB HID driver, make polling interval configurable.
When setting usb_mode to "HID", hid config object now has
polling-interval (in ms) as the 4th element.  It mmust now be a 5-tuple
of the form:

(subclass, protocol, max_packet_len, polling_interval, report_desc)

The mouse and keyboard defaults have polling interval at 8ms.

Daniel Campora 7b19e99edd lib: Update FatFs to R0.11.
There are lots of cosmetic changes, but this release brings a  very
important bug fix:
 - Fixed f_unlink() does not remove cluster chain of the file.

With R0.10c if you try to write a file that is too large to fit in the
free space of the drive, the operation fails, you delete the incomplete
file, and it seems to be erased, but the space is not really freed,
because any subsequent write operations fail because the drive is
"still" full. The only way to recover from this is by formatting the
drive. I can confirm that R0.11 fixes the problem.

Damien George cfe623ae3e stmhal: Expose all PYBv1.0 pins, include SD and USB pins.
To have proper low power mode, need to configure all unused pins in
input mode, so need to have them available.
2015-03-22 17:57:09 +00:00

Paul Sokolovsky 0ef01d0a75 py: Implement core of OrderedDict type.
Given that there's already support for "fixed table" maps, which are
essentially ordered maps, the implementation of OrderedDict just extends
"fixed table" maps by adding an "is ordered" flag and add/remove
operations, and reuses 95% of objdict code, just making methods tolerant
to both dict and OrderedDict.

Some things are missing so far, like CPython-compatible repr and comparison.

OrderedDict is Disabled by default; enabled on unix and stmhal ports.

Damien George 5cbeacebdb py: Make math special functions configurable and disabled by default.
The implementation of these functions is very large (order 4k) and they

Damien George 65af7ebdc5 stmhal: Put CDC last in config descriptors to match with iface nums.
Apparently the order of interface numbers should be sequential and

configs to the end of the descriptors, instead of changing the interface
numbers.

Damien George 0bfc7638ba py: Protect mp_parse and mp_compile with nlr push/pop block.
To enable parsing constants more efficiently, mp_parse should be allowed
to raise an exception, and mp_compile can already raise a MemoryError.
So these functions need to be protected by an nlr push/pop block.

This patch adds that feature in all places.  This allows to simplify how
mp_parse and mp_compile are called: they now raise an exception if they
have an error and so explicit checking is not needed anymore.

blmorris 97f14606f5 stmhal/adc.c: Fix calculation of read_core_vref()
There was a stray factor of 2 (VBAT_DIV) that looks like it was copied incorrectly from the read_core_vbat() function.
The factor exists in read_core_vbat() because VBAT is measured through a 2:1 voltage divider.
read_core_vref now returns values around 1.21V (assuming that external reference voltage is 3.3V) which is in line with the datasheet values.

Damien George 827b0f747b py: Change vstr_null_terminate -> vstr_null_terminated_str, returns str. 2015-01-29 13:57:23 +00:00
Damien George 0d3cb6726d py: Change vstr so that it doesn't null terminate buffer by default.
This cleans up vstr so that it's a pure "variable buffer", and the user
can decide whether they need to add a terminating null byte.  In most
places where vstr is used, the vstr did not need to be null terminated
and so this patch saves code size, a tiny bit of RAM, and makes vstr
usage more efficient.  When null termination is needed it must be
done explicitly using vstr_null_terminate.

Damien George ad33e2465c stmhal: Disable MICROPY_OPT_CACHE_MAP_LOOKUP_IN_BYTECODE.
It uses RAM and on pyboard we are generally tight on RAM, so disable
this optimisation for general builds.  If users need the speed then
they can build their own version.  Maybe in the future we can have
different versions of pyboard firmware built with different tradeoffs.

Damien George 23342c09ff stmhal: Bug fix for usocket's accept and setsockopt methods.
accept might raise an exception, in which case the new socket is not
fully created.  It has a finaliser so will run close() method when GC'd.
Before this patch close would try to close an invalid socket.  Now
fixed.

setsockopt took address of stack value which became out of scope.  Now
fixed.

2015-01-22 00:16:41 +00:00
Damien George 05005f679e py: Remove mp_obj_str_builder and use vstr instead.
With this patch str/bytes construction is streamlined.  Always use a
vstr to build a str/bytes object.  If the size is known beforehand then
use vstr_init_len to allocate only required memory.  Otherwise use
vstr_init and the vstr will grow as needed.  Then use
mp_obj_new_str_from_vstr to create a str/bytes object using the vstr
memory.

Saves code ROM: 68 bytes on stmhal, 108 bytes on bare-arm, and 336 bytes
on unix x64.

Paul Sokolovsky 87bc8e2b3d pyexec: Add event-driven variant pyexec_friendly_repl().
pyexec_friendly_repl_process_char() and friends, useful for ports which
integrate into existing cooperative multitasking system.

Unlike readline() refactor before, this was implemented in less formal,
trial&error process, minor functionality regressions are still known
(like soft&hard reset support). So, original loop-based pyexec_friendly_repl()
is left intact, specific implementation selectable by config setting.
2015-01-16 01:30:42 +02:00
Damien George cd34207409 py: Can compile with -Wmissing-declarations and -Wmissing-prototypes. 2015-01-12 22:30:49 +00:00
Damien George 131185a2b8 stmhal: Add MICROPY_HW_USB_OTG_ID_PIN config, set for relevant boards.
This config option is for the USB OTG pin, pin A10.  This is used on
some boards but not others.  Eg PYBv3 uses PA10 for LED(2), so it
shouldn't be used for OTG ID (actually PA10 is multiplexed on this
board, but defaults to LED(2)).

Partially addresses issue #1059.

Damien George 89deec0bab py: Add MICROPY_PY_MICROPYTHON_MEM_INFO to enable mem-info funcs.
This allows to enable mem-info functions in micropython module, even if
MICROPY_MEM_STATS is not enabled.  In this case, you get mem_info and
qstr_info but not mem_{total,current,peak}.

Damien George 181bfb6db2 stmhal: Add MICROPY_HW_USB_VBUS_DETECT_PIN option, for boards without it
Since all currently supported boards use pin A9 for this function, the
value of the macro MICROPY_HW_USB_VBUS_DETECT_PIN is not actually used,
just the fact that it is defined.

2015-01-07 23:54:57 +00:00
Damien George 3b51b3e90f stmhal: Collect all root pointers together in 1 place.
A GC in stmhal port now only scans true root pointers, not entire BSS.
This reduces base GC time from 1700ms to 900ms.
2015-01-07 23:38:50 +00:00
Damien George 7ee91cf861 py: Add option to cache map lookup results in bytecode.
This is a simple optimisation inspired by JITing technology: we cache in
the bytecode (using 1 byte) the offset of the last successful lookup in
a map. This allows us next time round to check in that location in the
hash table (mp_map_t) for the desired entry, and if it's there use that
entry straight away.  Otherwise fallback to a normal map lookup.

Works for LOAD_NAME, LOAD_GLOBAL, LOAD_ATTR and STORE_ATTR opcodes.

On a few tests it gives >90% cache hit and greatly improves speed of
code.

Disabled by default.  Enabled for unix and stmhal ports.
2015-01-07 21:07:23 +00:00
Damien George b4b10fd350 py: Put all global state together in state structures.
This patch consolidates all global variables in py/ core into one place,

Damien George f04329e93b lib/libm: Add acosh, asinh, atanh, tan; get working with stmhal.
acoshf, asinhf, atanhf were added from musl.  mathsincos.c was
split up into its original, separate files (from newlibe-nano-2).
tan was added.

All of the important missing float functions are now implemented,
and pyboard now passes tests/float/math_fun.py (finally!).
2014-12-18 14:44:02 +00:00
Damien George 78d702c300 py: Allow builtins to be overridden.
This patch adds a configuration option (MICROPY_CAN_OVERRIDE_BUILTINS)
which, when enabled, allows to override all names within the builtins
module.  A builtins override dict is created the first time the user
assigns to a name in the builtins model, and then that dict is searched
first on subsequent lookups.  Note that this implementation doesn't
allow deleting of names.

This patch also does some refactoring of builtins code, creating the
modbuiltins.c file.

Addresses issue #959.

Paul Sokolovsky 46c3ab2004 modsys: Add sys.print_exception(exc, file=sys.stdout) function.
The function is modeled after traceback.print_exception(), but unbloated,
and put into existing module to save overhead on adding another module.
Compliant traceback.print_exception() is intended to be implemented in
micropython-lib in terms of sys.print_exception().

This change required refactoring mp_obj_print_exception() to take pfenv_t
interface arguments.

Addresses #751.

Damien George d0caaadaee stmhal: Allow network, uselect, usocket mods to be used by other ports.
Remove include of stm32f4xx_hal.h, replace by include of MICROPY_HAL_H

Damien George be6d8be91e py: Rename mp_obj_int_get to mp_obj_int_get_truncated; fix struct.pack.
mp_obj_int_get_truncated is used as a "fast path" int accessor that
doesn't check for overflow and returns the int truncated to the machine
word size, ie mp_int_t.

Use mp_obj_int_get_truncated to fix struct.pack when packing maximum word
sized values.

Addresses issues #779 and #998.
2014-12-05 23:13:52 +00:00
Damien George a4c52c5a3d py: Optimise lexer by exposing lexer type.
mp_lexer_t type is exposed, mp_token_t type is removed, and simple lexer
functions (like checking current token kind) are now inlined.

This saves 784 bytes ROM on 32-bit unix, 348 bytes on stmhal, and 460
bytes on bare-arm.  It also saves a tiny bit of RAM since mp_lexer_t
is a bit smaller.  Also will run a bit more efficiently.
2014-12-05 19:35:18 +00:00
Damien George 29a1ec1bd6 stmhal: Overhaul network drivers; has generic network protocol in C.
This patch overhauls the network driver interface.  A generic NIC must
provide a set of C-level functions to implement low-level socket control
(eg socket, bind, connect, send, recv).  Doing this, the network and
usocket modules can then use such a NIC to implement proper socket
control at the Python level.

This patch also updates the CC3K and WIZNET5K drivers to conform to the
new interface, and fixes some bugs in the drivers.  They now work
reasonably well.

Damien George 1960475ed7 stmhal: Make pyb.[u]delay use systick with IRQs, busy loop otherwise.
pyb.delay and pyb.udelay now use systick if IRQs are enabled, otherwise
they use a busy loop.  Thus they work correctly when IRQs are disabled.
The busy loop is computed from the current CPU frequency, so works no
matter the CPU frequency.

2014-11-27 17:54:37 +00:00
Damien George 317cf18486 stmhal: Remove unnecessary HAL_Delay in readline loop.
The reason for having this delay is to reduce power consumption at the
REPL (HAL_Delay calls __WFI to idle the CPU).  But stdin_rx_chr has a
__WFI in it anyway, so this delay call is not needed.

By removing this call, the readline input can consume characters much
more quickly (before was limited to 1000 chrs/s), and has much reduced
dependency on the specific port.
2014-11-27 17:04:09 +00:00

        select.select([usb, uart], [], [])
        if usb.any():
            uart.write(usb.read(256))
        if uart.any():

2014-10-26 21:46:06 +00:00
Damien George bc1488a05f stmhal: Improve REPL control codes; improve pyboard.py script.
Improvements are:

2 ctrl-C's are now needed to truly kill running script on pyboard, so
make CDC interface allow multiple ctrl-C's through at once (ie sending
b'\x03\x03' to pyboard now counts as 2 ctrl-C's).

ctrl-C in friendly-repl can now stop multi-line input.

In raw-repl mode, use ctrl-D to indicate end of running script, and also
end of any error message.  Thus, output of raw-repl is always at least 2
ctrl-D's and it's much easier to parse.

pyboard.py is now a bit faster, handles exceptions from pyboard better
(prints them and exits with exit code 1), prints out the pyboard output
while the script is running (instead of waiting till the end), and
allows to follow the output of a previous script when run with no
arguments.

Damien George 124df6f8d0 py: Add mp_pending_exception global variable, for VM soft interrupt.
This allows to implement KeyboardInterrupt on unix, and a much safer
ctrl-C in stmhal port.  First ctrl-C is a soft one, with hope that VM
will notice it; second ctrl-C is a hard one that kills anything (for
both unix and stmhal).

One needs to check for a pending exception in the VM only for jump
opcodes.  Others can't produce an infinite loop (infinite recursion is
caught by stack check).

Timeouts are configured when the UART object is initialised, using
timeout and timeout_char keyword args.

The object includes optional read buffering, using interrupts.  You can set
the buffer size dynamically using read_buf_len keyword arg.  A size of 0
disables buffering.

stmhal: Set entry point for ELF binary debugging
2014-10-21 20:58:29 +01:00
stijn 2fe4cf7761 Implement kwargs for builtin open() and _io.FileIO
This makes open() and _io.FileIO() more CPython compliant.
The mode kwarg is fully iplemented.
The encoding kwarg is allowed but not implemented; mainly to allow
the tests to specify encoding for CPython, see #874

Sven Wegener abf0f07a5a stmhal: Set entry point for ELF binary debugging
When loading the ELF binary to the board with a debugger, the debugger
needs to know at which point to start executing the code. Currently the
entry point defaults to the start of the .text section.

Damien George 24119176e7 stmhal: Allow pyb.freq() function to change SYSCLK frequency.
Eg pyb.freq(120000000) sets the CPU to 120MHz.  The frequency can be set
at any point in the code, and can be changed as many times as you like.
Note that any active timers will need to be reconfigured after a freq
change.

Valid range is 24MHz to 168MHz (but not all freqs are supported).  The
code maintains a 48MHz clock for the USB at all times and it's possible
to change the frequency at a USB REPL and keep the REPL alive (well,
most of the time it stays, sometimes it resets the USB for some reason).
Note that USB does not work with pyb.freq of 24MHz.

Damien George 3a1c4c5bc6 stmhal: Add network and usocket module.
As per issue #876, the network module is used to configure NICs
(hardware modules) and configure routing.  The usocket module is
supposed to implement the normal Python socket module and selects the
underlying NIC using routing logic.

Right now the routing logic is brain dead: first-initialised,
first-used.  And the routing table is just a list of registered NICs.

cc3k and wiznet5k work, but not at the same time due to C name clashes
(to be fixed).

Note that the usocket module has alias socket, so that one can import
socket and it works as normal.  But you can also override socket with
your own module, using usocket at the backend.

Damien George bfa7b480a7 stmhal: For spi_init, add argument to select if NSS pin is enabled.

In CPython IOError (and EnvironmentError) is deprecated and aliased to

In Micro Python we never used IOError (except 1 place, incorrectly) and
so don't need to keep it.

Dave Hylands 39296b40d4 Fix timer overflow code.
Teensy doesn't need to worry about overflows since all of
its timers are only 16-bit.

For PWM, the pulse width needs to be able to vary from 0..period+1
(pulse-width == period+1 corresponds to 100% PWM)

I couldn't test the 0xffffffff cases since we can't currently get a
period that big in python. With a prescaler of 0, that corresponds
to a freq of 0.039 (i.e. cycle every 25.56 seconds), and we can't
set that using freq or period.

I also tested both stmhal and teensy with floats disabled, which
required a few other code changes to compile.

Damien George 52b5d76a6b py: Free non-interned strings in the parser when not needed.
mp_parse_node_free now frees the memory associated with non-interned
strings.  And the parser calls mp_parse_node_free when discarding a
non-used node (such as a doc string).

Also, the compiler now frees the parse tree explicitly just before it
exits (as opposed to relying on the caller to do this).

Damien George eaaebf3291 stmhal: Initialise stack pointer correctly.
Stack is full descending and must be 8-byte aligned.  It must start off

Previously, stack started pointed to last byte of RAM (eg 0x2001ffff)
and so was not 8-byte aligned.  This caused a bug in combination with
alloca.

This patch also updates some debug printing code.

This allows to set the pulse width (for PWM mode) as a ratio relative to

ratio in the channel init, or using channel.pulse_width_ratio; the
latter can also read the pulse width as a ratio.
