Damien George f4c17378b3 stmhal: Protect SD card DMA transactions against USB MSC contention.
Consider the following scenario: SD card is being read by pyboard; USB
irq comes in for MSC read request; SD card needs to be read from within
USB irq while SD read is already ongoing.  Such contention needs to be
avoided.

This patch provides a simple solution, to raise the irq priority above
that of the USB irq during SD DMA transfers.  Pyboard and PC can now
read from the SD card at the same time (well, reads are interleaved).

Damien George 95c9cc8114 stmhal: Add raise_irq_pri and restore_irq_pri functions.
These can be used to disable only certain interrupts, ones at or above
the given priority value.

Damien George 0d9b450701 stmhal: Make uart.write() function correctly for timeout=0.
In non-blocking mode (timeout=0), uart.write() can now transmit all of its
data without raising an exception.  uart.read() also works correctly in
this mode.

As part of this patch, timout_char now has a minimum value which is long
enough to transfer 1 character.

Addresses issue #1533.

Dave Hylands 3048433809 stmhal: Make stm.mem* support large integers.
With these you can now do things like:

stm.mem32[0x20000000] = 0x80000000

and read 32-bit values. You can also read all the way to the end
of memory using either stm.mem32[0xfffffffc] or stm.mem32[-4].

IRQs shouldn't use mem32 at all since they'd fail if the top 2 bits
weren't equal, so IRQs should be using 16-bit I/O.

Dave Hylands 061eb6fa6b stmahl: Fix usbd_conf.c for devices which don't have USB_HS at all.
The STMCube examples define both USE_USB_HS and USE_USB_HS_IN_FS when they
use the HS in FS mode.

The STM32F401 doesn't have a USB_HS at all, so the USB_OTG_HS instance
doesn't even exist.

Dave Hylands c8437f97ae stmhal: Increase the priority of UART IRQ.
The UARTs have no FIFOs, so if interrupts are disabled
for more than a character time (10 usec at 1 Mbit/sec)
then characters get dropped.

The overhead for handling a UART ISR is about 0.5 usec,
so even at baud rates of 1 Mbit/sec this only corresponds
to about 5% of the CPU. Lower baud rates will have less
of an impact.

Damien George 36bd10779c stmhal: In SysTick IRQ handler, make uwTick variable non-volatile.
uwTick can only change in the SysTick IRQ so this IRQ function does not
need to take special care with this variable.  It's important to make
this IRQ function as efficient as possible.

Damien George e99e6c883d stmhal: Move flash storage idle tick handler from TIM3 to SysTick.
Using SysTick to do the counting and dispatch of the flash storage idle
handler is more efficient than requiring a dedicated hardware timer.
No new counter is needed, just the existing uwTick variable.  The
processing is not actually done in the SysTick IRQ, it is deferred to
the flash IRQ (which runs at lower priority).

Dave Hylands b677f03407 stmhal: Turn off DMA clocks when idle for 100 msec
Turning on each DMA block increases the current consumption
by about 8 mA. This code adds an idle timer for each DMA
block and turns off the clocks when no streams are in use
for 128 msec. Having a small timeout allows for improved
performance when back-to-back transfers are being performed.

The 128 msec is basically a guess.

  for sdcard I/O when using USB Mass Storage.

T S 86aa16bea6 stmhal: Implement delayed RTC initialization with LSI fallback.
If RTC is already running at boot then it's left alone.  Otherwise, RTC is
started at boot but startup function returns straight away.  RTC startup
is then finished the first time it is used.  Fallback to LSI if LSE fails
to start in a certain time.

Also included:
 MICROPY_HW_CLK_LAST_FREQ
        hold pyb.freq() parameters in RTC backup reg
 MICROPY_HW_RTC_USE_US
        option to present datetime sub-seconds in microseconds
 MICROPY_HW_RTC_USE_CALOUT
        option to enable RTC calibration output

CLK_LAST_FREQ and RTC_USE_CALOUT are enabled for PYBv1.0.

Paul Sokolovsky 16d42368a6 stmhal/modmachine: Initial attempt to add I2C & SPI classes.
In new hardware API, these classes implement master modes of interfaces,
and "mode" parameter is not accepted. Trying to implement new HW API
in terms of older pyb module leaves variuos corner cases:

In new HW API, I2C(1) means "I2C #1 in master mode" (? depends on
interpretation), while in old API, it means "I2C #1, with no settings
changes".

For I2C class, it's easy to make mode optional, because that's last
positional param, but for SPI, there's "baudrate" after it (which
is inconsistent with I2C, which requires "baudrate" to be kwonly-arg).

Paul Sokolovsky 0dbd928cee Makefiles: Remove duplicate object files when linking.
Scenario: module1 depends on some common file from lib/, so specifies it
in its SRC_MOD, and the same situation with module2, then common file
from lib/ eventually ends up listed twice in $(OBJ), which leads to link
errors.

Make is equipped to deal with such situation easily, quoting the manual:
"The value of $^ omits duplicate prerequisites, while $+ retains them and
preserves their order." So, just use $^ consistently in all link targets.

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 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'.

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 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.

Dave Hylands 7c934ae501 stmhal: Add hal and cmsis files from STM32Cube_FW_F7_V1.1.0.
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.
2015-07-30 00:38:18 +01:00

Should fix issue #1393.
2015-07-27 23:52:56 +01:00
Damien George 92e9a5e0a7 stmhal: Check if user block device is mounted before accessing it.
In particular this fixes a bug where pyb.sync (and os.sync) fail because
they try to sync the user mounted device even if it's not mounted.
2015-07-27 23:40:19 +01:00
Tom Soulanille 7d588b0c7c lib/mp-readline: Add emacs-style control characters for cursor movement.

2015-07-26 15:22:13 +01:00
Damien George 7693ef3bd6 stmhal: Allow ADC.read_timed to take Timer object in place of freq.
This allows a user-specified Timer for the triggering of the ADC read,
mirroring the new behaviour of DAC.write_timed.

Addresses issue #1129.
2015-07-22 19:41:13 +01:00
Damien George 99a21dc05d stmhal: Add stm32fxxx_hal_i2s_ex.c to hal/f2 (dummy) and hal/f4. 2015-07-21 23:49:19 +01:00
Damien George abc24c1876 stmhal: Allow DAC.write_timed to take Timer object in place of freq.
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.
2015-07-21 23:39:49 +01:00
Damien George 6f5e0fe955 stmhal: Clean up DAC code a little. 2015-07-21 22:05:56 +01:00

of the alternate functions in the pin struct
2015-07-20 16:19:12 +01:00
Damien George f576057274 stmhal: Add CMSIS device header files for STM32F2xx series. 2015-07-20 12:33:05 +01:00
Wojtek Siudzinski 0621eca05e stmhal: Add STM32CubeF2 version 1.1.0, in hal/f2 directory.
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.
2015-07-20 12:32:09 +01:00
Damien George a39df51d8a stmhal: Update Makefile and board configs to compile with relocated hal. 2015-07-20 12:30:18 +01:00
Damien George e4d43401eb stmhal: Move HAL Cube files to f4/ subdir, keeping only those we use.
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.
2015-07-20 12:30:18 +01:00
Dave Hylands 9309e609cd stmhal: Add qstr definition for ifconfig when building for WizNet 2015-07-14 23:00:29 +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.
2015-06-27 23:27:23 +01:00
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.
2015-06-24 17:48:52 +01:00
Damien George 6e1dfb0d1a stmhal: Reorganise code for parsing keyword args in I2C methods.

2015-06-10 14:01:44 +01:00
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.
2015-06-07 23:48:07 +01:00
Damien George 53a8aeb6e7 stmhal: Fix slow SPI DMA transfers by removing wfi from DMA wait loop.

Damien George c50772d19f py: Add mp_obj_get_int_truncated and use it where appropriate.
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.
