Damien George 9d0192de4a stmhal: Enable "all special methods" configuration option. 2015-10-20 23:55:27 +01:00
Damien George 60401d461a stmhal/rtc: Fix indentation to use spaces rather than tabs. 2015-10-20 12:05:27 +01:00
Peter Hinch b106532b32 stmhal/rtc: Init uses YMD rather than backup register to detect powerup. 2015-10-20 12:05:16 +01:00
Damien George 2f96b1982a stmhal: Bring Pin class close to new machine module specification.
Looks like we can use the same Pin class for legacy pyb module and new
machine module.

Paul Sokolovsky bedab235f9 stmhal/uart: If char is not received within timeout, return EAGAIN error.
Instead of return 0, which means EOF. There's no good way to detect EOF on
continuously active bus like UART, and treat timeout as just temporary
unvailability of data. .read() method of UART object will return None in
this case (instead of 0, which again measn EOF). This is fully compliant
with unix port.

Damien George 83158e0e7f stmhal: Implement os.dupterm (was pyb.repl_uart).
pyb.repl_uart still exists but points to os.dupterm.

Damien George d8066e999d stmhal: Add sleep_{ms,us} and ticks_{ms,us,cpu,diff} to time module.
pyb module still has pyb.delay and pyb.udelay, but these now point to
time.sleep_ms and time.sleep_us respectively.

Dave Hylands 504420c51d stmhal: Early version of machine module for stmhal. 2015-10-19 21:12:42 +01:00
Paul Sokolovsky e0f5df579b all: Make netutils.h available to all ports by default.
Generally, ports should inherit INC from py.mk, append to it, not
overwrite it. TODO: Likely should do the same for other vars too.

Damien George b5c43be135 stmhal: Allow to set bits resolution for DAC; 8 is default, can have 12.
This patch allows to configure the DAC resolution in the constructor and
in the init function, eg:

dac = DAC(1, bits=12).

The default resolution is 8 bits for backwards compatibility.  The bits
sets the maximum value accepted by write and write_timed methods, being
2**bits - 1.

When using write_timed with 12-bit resolution, the input buffer is
treated as an unsigned half-word array, typecode 'H'.

See PR #1130 for discussion.

Damien George 0334058fa4 Rename "Micro Python" to "MicroPython" in REPL, help, readme's and misc. 2015-10-12 00:06:25 +01:00
Damien George 6206f431cf stmhal: Enable REPL auto indent; document paste mode in help(). 2015-10-11 23:33:46 +01:00
Damien George 46a1102852 repl: Add paste mode to friendly REPL, entered via CTRL-E.
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.

Dave Hylands 01d64914c5 stmhal: Fix USB CDC-only mode under Windows.
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.

Damien George 58e0f4ac50 py: Allocate parse nodes in chunks to reduce fragmentation and RAM use.
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.

Damien George d80174d7c3 stmhal: Use polling, not DMA, for 1 byte SPI transfers.
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.

Tom Soulanille 7731edf2f5 stmhal: Add "opt" arg to pyb.main, to set mp_optimise_value.
Use this to set the global optimisation value when executing the main
script (and all scripts it imports).

Tony Abboud 8d8fdcb4be stmhal: add option to query for the current usb mode
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.

Dave Hylands 9e8eba797e stmhal: M7 Reset clocksources changed by DFU bootloader
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.

Dave Hylands 8f1eced69d stmhal: Add STM32F7 support for USB serial and storage.
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.
