In this commit, the analogin_s structure is moved to commonn_objects.h file
to limit the duplicaion.
The ADC handle is moved from a global variable to a struct member of the
analogin object. This allows multiple ADC instances to work correctly.
Note that State needs to be explicitely set to HAL_ADC_STATE_RESET
because the object is not zero initialized.
Moving some code in common to be able to manage several ADC instances,
or several channels of an instance.
The change involves:
- moving dac_s structure definition to common_object.h
- create TARGET_STM/analogout_api.c and move fully common analog_out
functions in there
- rename analogout_api.c of each target family into analogout_device.c
to keep platform specific code
- update analogout_device.c to rely on obj->handle and obj->channel
- align analogout_init function as much as possible between families in
analogout_device.c files
Since most of the code in i2c_api.c is now relying on STM32 HAL, there
is now a possibility to make a common usage of this code accross families.
The IP version definition is introduced per family, to allow a switch of
functionnalities, especially the frequency management which differs.
BTw, we fix the F0 frequency settings at the same time.
F1 is managed for now as an exception as the HAL API for sequential transmit
/receive is not yet available (coming soon)
the SPI_ASYNCH feature has been already activated for STM32F4.
This patchset makes it supported on all STM32 families by:
- moving spi_s structure at family level instead of board level
- using the F4 spi_api.c reference implementation and making it a common
stm_spi_api.c file which makes maintenance a lot easier.
- the only part that needs to be implemented for each family is the computation
of the clock frequency input to the spi peripheral which is not the same
accross families. So this is what remains in the spi_api.c of each family.
Because of the introduction of the common file, all the above modifications
needs to be done at once.
