Paul Sokolovsky 59a1201da9 all: Remove readall() method, which is equivalent to read() w/o args.
Its addition was due to an early exploration on how to add CPython-like
stream interface. It's clear that it's not needed and just takes up
bytes in all ports.

Damien George 1375c52772 stmhal: Rename mp_hal_pin_set_af to _config_alt, to simplify alt config.
This way the caller doesn't need to initialise a big GPIO_InitTypeDef
struct, and HAL_GPIO_Init is no longer called.

Damien George 74fb5d6932 stmhal/i2c: Reset the I2C peripheral if there was an error on the bus.
If an I2C send/recv fails then the peripheral is now checked to see if
it's in a "stuck" state waiting for the stop bit, and if so then it is
reset so that the next I2C transaction can proceed.

This patch also de-inits the I2C peripheral in the init() method, before
init'ing it again.

Damien George c4e58eaa98 stmhal/i2c: Add option to I2C to enable/disable use of DMA transfers.
New keyword option in constructor and init() method is "dma=<bool>".
DMA is now disabled by default for I2C transfers because it currently does
not handle I2C bus errors very well (eg if slave device doesn't ACK or
NACK correctly during a transfer).
2016-11-11 17:36:19 +11:00
Damien George e6da6a720f stmhal/dma: De-init the DMA peripheral properly before initialising.
The DMA state is always HAL_DMA_STATE_RESET because of the memset clearing
all the data, so prior to this patch HAL_DMA_DeInit was never called.  Now
it is always called to make sure the DMA is properly reset.

Damien George bdf33bc136 py: Move frozen bytecode Makefile rules from ports to common mk files.
Now, to use frozen bytecode all a port needs to do is define
FROZEN_MPY_DIR to the directory containing the .py files to freeze, and
define MICROPY_MODULE_FROZEN_MPY and MICROPY_QSTR_EXTRA_POOL.

Damien George 4ebdb1f2b2 py: Be more specific with MP_DECLARE_CONST_FUN_OBJ macros.
In order to have more fine-grained control over how builtin functions are
constructed, the MP_DECLARE_CONST_FUN_OBJ macros are made more specific,
with suffix of _0, _1, _2, _3, _VAR, _VAR_BETEEN or _KW.  These names now
match the MP_DEFINE_CONST_FUN_OBJ macros.

Dave Hylands 1f433c719b stmhal: Fix linker map for STM32L476 chips.
In particular, this makes the L4 .isr_vector section 16K in size so it's
the same as the F4/F7 MCUs.  The patch also moves the L4 filesystem to
the end of flash, which allows for 512K filesystem on the 1Mb devices
like the STM32L476DISC.

Damien George bd925b59c3 stmhal/spi: Enable use of fast software SPI. 2016-10-04 13:51:30 +11:00
Damien George b932b2dd1f extmod/machine_spi: Use delay_half, not baudrate, for internal timing.
The delay_half parameter must be specified by the port to set up the
timing of the software SPI.  This allows the port to adjust the timing
value to better suit its timing characteristics, as well as provide a
more accurate printing of the baudrate.

Damien George 9f1e395c16 stmhal/spi: Use software SPI if no periph id given, even if pins given.
It's simpler to just default to always using software SPI if no specific
peripheral id/name is given.  To use hardware SPI users must specify a
hardware peripheral id as the first parameter to the SPI constructor.

Damien George a22a67661a stmhal/spi: Simplify spi_transfer function to take only one buf len arg. 2016-10-03 12:47:56 +11:00
Damien George 5bb28c7f10 extmod/machine_spi: Simplify SPI xfer function to only take one buf len.
There is no need to take src_len and dest_len arguments.  The case of
reading-only with a single output byte (originally src_len=1, dest_len>1)
is now handled by using the output buffer as the input buffer, and using
memset to fill the output byte into this buffer.  This simplifies the
implementations of the spi_transfer protocol function.

Damien George 4874bde104 stmhal/boards: For OLIMEX_E407, enable UART1 and fix I2C1 mapping.
UART1 can be used even if the switch is enabled.  The schematics for this

Krzysztof Blazewicz 1ba516f475 stmhal/extint: Force 0 to 1 transition on swint().
If a user tries to call `swint()` while interrupt is disabled the flag in
SWIER is set but the interrupt is not triggered and therefore the SWIER bit
is not cleared.  When the interrupt is again enabled the next call to
`swint()` won't trigger the IRQ because a 0 to 1 transition will not occur.

Tom Soulanille d89de18f40 stmhal/lcd: De-assert chip select after completing SPI transmission.
The LCD interface library fails to deassert the chip select of the LCD
after an SPI transmission.  Consequently using the SPI with other

lcd.lcd_out() to deassert CS after each transmission to the LCD.

Delio Brignoli e2ac8bb3f1 py: Add MICROPY_USE_INTERNAL_PRINTF option, defaults to enabled.
This new config option allows to control whether MicroPython uses its own

Accompanying this new option is the inclusion of lib/utils/printf.c in the
core list of source files, so that ports no longer need to include it
themselves.

Dave Hylands c6983e3ce0 stmhal: Fix timer capture/compare interrupt handling for TIM1 and TIM8.
It turns out that TIM1 and TIM8 have their own Capture/Compare
interrupt vector. For all of the other timers, the capture/compare
interrupt vector is the same as the update vector.

So we need to add handlers for these vectors and enable them
when using capture/compare callbacks.

During testing of this, I also found that passing a channel callback
into the channel constructor would not enable interrupts properly.

I tested using:
```
>>> pyb.Timer(1, freq=4).channel(1, pyb.Timer.OC_TOGGLE, callback=lambda t: print('.', end=''))
```
I tested the above with channels 1, 4, and 8

Tobias Badertscher af9889f99a stmhal/adc.c: Get ADC working on STM32L4 MCUs.
Fixing Issue #2243. Main problems were:

- HAL_ADC_GetState(adcHandle) may return other bits set (not only
  HAL_ADC_STATE_EOC_REG) when called - so I AND-ed it out as proposed by
  mattbrejza in Issue #2243.
- ADC Pin has to be configured as GPIO_MODE_ANALOG_ADC_CONTROL not only
  GPIO_MODE_ANALOG.
- Resolved ADC resolution L4 specific (Use L4 define ADC_RESOLUTION_12B).
- Changed setting of Init.EOCSelection toADC_EOC_SINGLE_CONV for L4.
- Added call to ADC_MultiModeTypeDef as this is done on a STM32Cube
  generated project too.
- Clean up: Configuration of ADC is done only in ONE function not the same
  is done in two functions.

Test is done on PA5 pin of STM32L4Discovery-Kit which is connected to the
DOWN button.

Thanks to mattbrejza for discovering the bug.

Tobias Badertscher e64032d6fd stmhal: L4: Adapt DMA to be able to support STM32L4 MCU series.
The main thing is to change the DMA code in a way that the structure
DMA_Stream_TypeDef (which is similar to DMA_Channel_TypeDef on stm32l4)
is no longer used outside of dma.c, as this structure only exists for the
F4 series.  Therefore I introduced a new structure (dma_descr_t) which
handles all DMA specific stuff for configuration.  Further the periphery
(spi, i2c, sdcard, dac) does not need to know the internals of the dma.

Tobias Badertscher 495da15611 stmhal: L4: Add support for external interrupts/events.
The L4 MCU supports 40 Events/IRQs lines of the type configurable and
direct.  But this L4 port only supports configurable line types which are
already supported by uPy.  For details see page 330 of RM0351, Rev 1.

The USB_FS_WAKUP event is a direct type and there is no support for it.

__GPIOI_CLK_ENABLE is defined in hal/l4/inc/Legacy/stm32_hal_legacy.h

anywhere else (because the L4 does not have port GPIOI).  So the test
for GPIOI is needed, along with the test for the CLK_ENABLE macro.

64-bit integer division brings a dependency on library functions. It is

- add template rule that converts a specified source file into a qstring file

- add special rule for generating a central header that contains all
  extracted/autogenerated strings - defined by QSTR_DEFS_COLLECTED
  variable. Each platform appends a list of sources that may contain
  qstrings into a new build variable: SRC_QSTR. Any autogenerated
  prerequisities are should be appened to SRC_QSTR_AUTO_DEPS variable.

- remove most qstrings from py/qstrdefs, keep only qstrings that
  contain special characters - these cannot be easily detected in the
  sources without additional annotations

- remove most manual qstrdefs, use qstrdef autogen for: py, cc3200,
  stmhal, teensy, unix, windows, pic16bit:

   - remove all micropython generic qstrdefs except for the special strings that contain special characters (e.g. /,+,<,> etc.)
   - remove all port specific qstrdefs except for special strings
   - append sources for qstr generation in platform makefiles (SRC_QSTR)

Paul Sokolovsky 9e0478a902 stmhal/diskio: Add provision for default returns for ioctl INIT/SEC_SIZE.
If None was returned for such requests (which likely means that user simply

Damien George b33a770596 extmod/fsusermount: Support mounting of multiple block devices.
This patch adds support to fsusermount for multiple block devices
(instead of just one).  The maximum allowed is fixed at compile time by
the size of the fs_user_mount array accessed via MP_STATE_PORT, which
in turn is set by MICROPY_FATFS_VOLUMES.

With this patch, stmhal (which is still tightly coupled to fsusermount)
is also modified to support mounting multiple devices   And the flash and
SD card are now just two block devices that are mounted at start up if
they exist (and they have special native code to make them more
efficient).

The new ioctl method handles the old sync and count methods, as well as
a new "get sector size" method.

If MICROPY_VFS_FAT is defined, mp_type_fileio & mp_type_textio won't be
defined, as these may be alredy defined elsewhere. The idea is to have
compartmentalized VFS FatFs class, which can work in parallel with some
other "main" filesystem. E.g., for unix port, mp_type_fileio, etc. will
be defined for the main POSIX filesystem, while stmhal/file.c will be
a self-contained VFS file class.

the general functions are used for all operations.

Damien George ea040a4f9a stmhal: In HAL I2C driver, move DMA setup to after sending I2C address.
Previous to this patch the DMA was setup and then the I2C address sent.
If the I2C address sending failed (eg no I2C device on the bus) then the
DMA was left in an inconsistent state.

This patch moves the DMA setup to after a successful sending of the I2C
address(es).

Damien George a8a4b01af6 stmhal: Add PWM capability for LED(3) and LED(4) on pyboards.
USB CDC no longer needs TIM3 (which was originally used for LED(4) PWM)
and so TIM3 has been freed for general purpose use by the user.  Hence
LED(4) lost its PWM capabilities.

This patch reinstates the PWM capabilities using a semi-generic piece
of code which allows to configure a timer and PWM channel to use for any
LED.  But the PWM capability is only configured if the LED is set to an
intensity between 1 and 254 (ie only when needed).  In that case the
relevant timer is configured for PWM.  It's up to the user to make sure
the timers are not used if PWM is active.

This patch also makes sure that PWM LEDs are turned off using standard
GPIO when calling led.off() or led.intensity(0), instead of just setting
the PWM counter to zero.
2016-01-29 22:44:43 +00:00
Damien George ea89b80ff4 stmhal: Make TIM3 available for use by the user.
TIM3 is no longer used by USB CDC for triggering outgoing data, so we

Damien George d363133917 stmhal: Make USB CDC driver use SOF instead of TIM3 for outgoing data.
Previous to this patch the USB CDC driver used TIM3 to trigger the
sending of outgoing data over USB serial.  This patch changes the
behaviour so that the USB SOF interrupt is used to trigger the processing
of the sending.  This reduces latency and increases bandwidth of outgoing
data.

Thanks to Martin Fischer, aka @hoihu, for the idea and initial prototype.

Paul Sokolovsky d3b1f0b627 py/runtime: mp_stack_ctrl_init() should be called immediately on startup.
Calling it from mp_init() is too late for some ports (like Unix), and leads
to incomplete stack frame being captured, with following GC issues. So, now
each port should call mp_stack_ctrl_init() on its own, ASAP after startup,
and taking special precautions so it really was called before stack variables
get allocated (because if such variable with a pointer is missed, it may lead
to over-collecting (typical symptom is segfaulting)).

Dave Hylands 42a6364a31 stmhal: Add support for building frozen files.
This allows FROZEN_DIR=some-directory to be specified on the make
command line, which will then add all of the files contained within
the indicated frozen directory as frozen files in the image.

There is no change in flash/ram usage if not using the feature.

This is especially useful on smaller MCUs (like the 401) which only
has 64K flash file system.

Damien George 5b3f0b7f39 py: Change first arg of type.make_new from mp_obj_t to mp_obj_type_t*.
The first argument to the type.make_new method is naturally a uPy type,
and all uses of this argument cast it directly to a pointer to a type
structure.  So it makes sense to just have it a pointer to a type from
the very beginning (and a const pointer at that).  This patch makes
such a change, and removes all unnecessary casting to/from mp_obj_t.

Paul Sokolovsky b4c65c253f extmod/fsusermount: Move module qstrs to global pool from stmhal port. 2015-12-25 19:22:16 +02:00
Damien George 401af50dc0 stmhal: Add pyb.irq_stats() to get statistics about IRQ calls.
Adds a lot of code, makes IRQs a bit less efficient, but is very useful
for debugging.  Usage: pyb.irq_stats() returns a memory view that can be
read and written, eg:

    list(pyb.irq_stats())
    pyb.irq_stats()[0]
    pyb.irq_stats()[0] = 0

The patch provides general IRQ_ENTER() and IRQ_EXIT() macros that can be
modified to provide further IRQ statistics if desired.

Damien George f7c4f9a640 stmhal: For SPI config, use HW_SPIx_SCK instead of HW_ENABLE_SPIx.
Previously, SPI was configured by a board defining MICROPY_HW_ENABLE_SPIx
to 0 or 1.  Now, the board should define MICROPY_HW_SPIx_SCK, MISO, MOSI
and NSS.  This makes it the same as how I2C is configured.

neilh10 1be0fde45c stmhal: Enable two USB phys to be supported together.
This is refactoring to enable support for the two USB PHYs available on
some STM32F4 processors to be used at the same time. The F405/7 & F429
have two USB PHYs, others such as the F411 only have one PHY.

This has been tested separately on a pyb10 (USB_FS PHY) and F429DISC
(USB_HS PHY) to be able to invoke a REPL/USB.  I have modified a PYBV10
to support two PHYs.

The long term objective is to support a 2nd USB PHY to be brought up as a
USB HOST, and possibly a single USB PHY to be OTG.

Dave Hylands f380904bd9 stmhal: Print exception information in nlr_jump_failed
Currently nlr_jump_fail prints that there was an uncaught exception
but nothing about the exception.
This patch causes nlr_jump_failed to try to print the exception.
Given that printf was called on the line above, I think that
the call to mp_obj_print_exception has about as much likelyhood
of succeeding as the printf does.

Dave Hylands acc208418b stmhal: Execute boot.py and main.py when formatting the file system.
When you use the USER button to perform a filesystem reset
at boot time then it wipes out the filesystem and creates
a new boot.py and main.py.  With this patch these files are
executed after formatting, ensuring that pyb and machine modules
get imported.

Damien George 66b96822fb stmhal: Add option to free up TIM3 from USB VCP polling.
This is a hack to free up TIM3 so that it can be used by the user.
Instead we use the PVD irq to call the USB VCP polling function, and
trigger it from SysTick (so SysTick itself does not do any processing).

The feature is enabled for pyboard lite only, since it lacks timers.

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 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.

The STMCube examples define both USE_USB_HS and USE_USB_HS_IN_FS when they

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

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.

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).
