Damien George ad7213d3c3 py: Add mp_raise_msg_varg helper and use it where appropriate. 
This commit adds mp_raise_msg_varg(type, fmt, ...) as a helper for
nlr_raise(mp_obj_new_exception_msg_varg(type, fmt, ...)).  It makes the
C-level API for raising exceptions more consistent, and reduces code size
on most ports:

Damien George d980d51807 stm32: Fix to build in nanbox mode. 2019-12-27 22:54:53 +11:00
Damien George c769da1aaa stm32/i2c: Support setting the I2C TIMINGR value via keyword arg. 
On MCUs that have an I2C TIMINGR register, this can now be explicitly set
via the "timingr" keyword argument to the I2C constructor, for both
machine.I2C and pyb.I2C.  This allows to configure precise timing values
when the defaults are inadequate.

Andrew Leech 17f7c683d2 stm32: Add support for STM32F765xx MCUs. 
This part is functionally similar to STM32F767xx (they share a datasheet)
so support is generally comparable.  When adding board support the
stm32f767_af.csv and stm32f767.ld should be used.

Damien George b0c8a94b41 stm32/dma: Pass DMA direction as parameter to dma_init not in cfg struct 
Some DMA channels (eg for SDIO) can be used in both directions and this
patch allows such peripherals to dynamically select the DMA direction.

Damien George e1ae9939ac stm32: Support compiling with object representation D. 
With this and previous patches the stm32 port can now be compiled using
object representation D (nan boxing).  Note that native code and frozen mpy
files with float constants are currently not supported with this object
representation.

Damien George 88c26a48b4 stm32/pyb_i2c: Put pyb.I2C under MICROPY_PY_PYB_LEGACY setting. 
When disabled, the pyb.I2C class saves around 8k of code space and 172
bytes of RAM.  The same functionality is now available in machine.I2C
(for F4 and F7 MCUs).

It is still enabled by default.

Damien George cb3456ddfe stm32: Don't use %lu or %lx for formatting, use just %u or %x. 
On this 32-bit arch there's no need to use the long version of the format
specifier.  It's only there to appease the compiler which checks the type
of the args passed to printf.  Removing the "l" saves a bit of code space.

Damien George 0c54d0c288 stm32: Rename legacy pyb.I2C helper functions to start with pyb_i2c_. 2018-04-24 17:32:16 +10:00
Damien George b73adcc3d9 stm32: Rename i2c.c to pyb_i2c.c. 
i2c.c implements the legacy pyb.I2C class so rename the file to make this
explicit, and also to make room for an improved I2C driver.
