Paul Sokolovsky 07209f8592 all: Rename mp_obj_type_t::stream_p to protocol. 
It's now used for more than just stream protocol (e.g. pin protocol), so
don't use false names.

Stefan Hölzl c8332a5463 stmhal: Add board definition files for Olimex STM32-E407. 2016-06-06 10:21:02 +01:00
Tobias Badertscher 1191ec6a14 stmhal/uart.c: Fix wrong baudrate calculation for stm32l4 series. 2016-06-03 14:24:59 +01:00
Peter Hinch 641300dccb stmhal/dac: DAC deinit() method added. 2016-05-31 13:10:35 +03:00
Paul Sokolovsky 2503b59592 stmhal/moduos: getcwd(): Use mp_obj_new_exception_arg1(). 
Argument types were converted, but old function call of
mp_obj_new_exception_msg_varg() remained.

Damien George 4b37e775ea extmod/machine_i2c: Redo mp_hal_pin macros to use open_drain and od_low. 
mp_hal_pin_config_od is renamed mp_hal_pin_open_drain, and mp_hal_pin_low
is mp_hal_pin_od_low.

Damien George 3e03d1b87e stmhal: Support frozen packages using .mpy files. 
See issue #1814.

Damien George 87981fc517 stmhal/sdcard: Allow to do unaligned read-from/write-to SD card. 
For example, the following code now works with a file on the SD card:

    f = open('test', 'rb') # test must be 1024 bytes or more in size
    f.seek(511)
    f.read(513)

Also works for writing.

Fixes issue #1863.

Damien George 1e388079f9 stmhal/i2c: Expose I2CHandle3 for use by custom C code. 
If custom C code uses the I2C busses then it needs access to these
structures for i2c_init().

Damien George 1dc2862a83 stmhal/led: Allow LEDs to be in PWM mode with TIM1 and channels 1-4. 
This allows PYBv3 to use PWM for LED(1) and LED(2).

Damien George 79a38a7a43 stmhal: For network drivers, convert to use MP_Exxx errno symbols. 2016-05-10 23:45:33 +01:00
Damien George 5ab98d5c41 stmhal: Convert to use internal errno symbols; enable uerrno module. 2016-05-10 23:30:39 +01:00
Tobias Badertscher b924f649cd stmhal: Fix clock configuration for STM32L476-discovery; also add I2C2. 2016-05-10 09:20:30 +01:00
Henrik Sölver c4587e2426 stmhal/can: Allow to get existing CAN obj if constructed without args. 
Initialisation of CAN objects should now behave as other peripheral
objects.

Fixes issue #2001.

Damien George 88153dc56a stmhal/sdcard: Fix initialisation of DMA TX so that writes work. 
Addresses issue #2034.

Dave Hylands cbbeb786d7 stmhal/dma: Fix builds for boards with an F4 or F7 but no DAC. 2016-05-06 09:57:33 +01:00
Damien George 08d3d5d9ab stmhal: For LIMIFROG board, add early-init function to get to DFU mode. 2016-05-05 17:00:30 +01:00
Tobias Badertscher 770f169e63 stmhal: Add board files for LIMIFROG board. 2016-05-05 17:00:16 +01:00
Damien George 05d1664981 stmhal/dma: Make DAC DMA descriptors conditional on having a DAC. 2016-05-05 15:34:01 +01:00
Tobias Badertscher 0f846e563c stmhal: L4: Add support for machine.sleep on STM32L4 MCUs. 
Also raise an exception for machine.freq and machine.deepsleep on this
MCU, since they are not yet implemented.

Tobias Badertscher 7441ba7749 stmhal: L4: Make CCM/DTCM RAM start-up conditional on MCU type. 2016-05-05 15:19:33 +01:00
Tobias Badertscher adaaf439b0 stmhal: L4: Adapt startup code, clock configuration and interrupts. 2016-05-05 15:14:42 +01:00
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.

Damien George 70ff7350e7 stmhal, cc3200: Change i2c.scan() method to scan addresses 0x08-0x77. 
A standard I2C address is 7 bits but addresses 0b0000xxx and 0b1111xxx
are reserved.  The scan() method is changed to reflect this, along with
the docs.

Damien George 12c61ddddd stmhal/accel: Raise an exception if the accel couldn't be initialised. 
On PYBLITEv1.0 there is no accelerometer and in this case the Accel()
constructor should not silently succeed.
