Use CTRL-E to enter paste mode. Prompt starts with "===" and accepts
all characters verbatim, echoing them back. Only control characters are
CTRL-C which cancels the input and returns to normal REPL, and CTRL-D
which ends the input and executes it. The input is executed as though
it were a file. The input is not added to the prompt history.
This fix adds PIDs 9801 and 9802 to the pybcdc.inf file.
When in CDC only mode, it presents itself as a Communcations
device rather than as a composite device. Presenting as a
composite device with only the CDC interface seems to confuse
windows.
To test and make sure that the correct pybcdc.inf was being used,
I used USBDeview from http://www.nirsoft.net/utils/usb_devices_view.html
to uninstall any old pyboard drivers (Use Control-F and search
for pyboard). I found running USBDeview as administrator worked best.
Installing the driver in CDC+MSC mode first is recommended (since the
pybcdc.inf file in on the internal flash drive). Then when you switch
modes everything seems to work properly.
I used https://github.com/dhylands/upy-examples/blob/master/boot_switch.py
to easily switch the pyboard between the various USB modes for testing.
With this patch parse nodes are allocated sequentially in chunks. This
reduces fragmentation of the heap and prevents waste at the end of
individually allocated parse nodes.
Saves roughly 20% of RAM during parse stage.
There is an issue sending 1 byte on the SPI bus using DMA, but it only
occurs when the transmit is done for the first time after initialising
the SPI and DMA peripherals. All other cases (sending 2 or more bytes,
doing send_recv, doing recv first) work okay. We sidestep this issue by
using polling (not DMA) for all 1 byte transfers. This is fine because
a 1 byte transfer can't be interrupted and doesn't need the benefits of
DMA (and using polling for this case is more efficient).
Resolves#1456.
Fetch the current usb mode and return a string representation when
pyb.usb_mode() is called with no args. The possible string values are interned
as qstr's. None will be returned if an incorrect mode is set.
The DFU bootloader on the ST32F7 chip changes the clocksource
for various possible boot sources (UART1, UART3, I2C1-3).
This commit resets those clock sources back to their cold
reset values.
USB serial is now working for F7.
Internal file storage is now working for F7. The flash is laid out a bit
differently to the F4 - 4 x 32K, 1 x 128K with the rest 256K, so the
internal storage is 96K.
Added more pind definitions for STM32F7DISC board. Made USART1 be the
default HWUART repl. The STLINK usb connector also looks like a USB
serial port which is attached to USART1 on the STM32F7DISC.
Extracted GPIO clock enable logic into mp_hal_gpio_clock_enable
and called from anyplace which might need to use GPIO functions
on ports other than A-D.
Thanks to Dave Hylands for the patch.
All files were converted to linux line endings.
All trailing whitespace was removed using:
for f in f7/inc/* f7/src/*; do sed --in-place 's/[[:space:]]\+$//' $f; done
All non-ascii chars in comments were replaced with ascii equivalents or
removed.
This allows the DAC to use a user-specified Timer for the triggering
(instead of the default Timer(6)), while still supporting original
behaviour.
Addresses issues #1129 and #1388.
Only those files which are needed by the stmhal port are added.
Also includes a dummy file (stm32f2xx_hal_pcd_ex.c) to keep the build
system the same for f4 and f2 MCU series.
This is in preparation for supporting other MCU series, such as
STM32F2xx. Directory structure for the HAL is now hal/f4/{inc,src},
where "f4" will in the future be different for other series.
HAL source/header files that are not use are removed to reduce the size
of the code.
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.
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.
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.
mp_obj_get_int_truncated will raise a TypeError if the argument is not
an integral type. Use mp_obj_int_get_truncated only when you know the
argument is a small or big int.
esp8266 port now has working raw and friendly REPL, as well as working
soft reset (CTRL-D at REPL, or raise SystemExit).
tools/pyboard.py now works with esp8266 port.
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
Each board now needs an mpconfigboard.mk file which defines AF_FILE and
LD_FILE.
Also moved stm32f405.ld to boards/ directory to keep things organised.
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.
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.
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.
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.
These allow to fine-tune the compiler to select whether it optimises
tuple assignments of the form a, b = c, d and a, b, c = d, e, f.
Sensible defaults are provided.
In particular, make sure that the globals are all initialized
before enabling the interrupt, and also make sure that the timer
interrupt has been initialied before enabling the NVIC.
The implementation of these functions is very large (order 4k) and they
are rarely used, so we don't enable them by default.
They are however enabled in stmhal and unix, since we have the room.
Apparently the order of interface numbers should be sequential and
increasing in a config descriptor. So as to retain compatibility with
Windows drivers for the CDC+MSC and CDC+HID modes, we move the CDC
configs to the end of the descriptors, instead of changing the interface
numbers.
