`led_init()` is already protected by an `#ifdef`, so no need for
the weak symbol.
The problem is that the weak function does not get overridden, even when
the board provides it's own led_init(), resulting in no LEDs being
initialized.
The setter function approach makes this switchable at runtime (antenna
diversity?).
Documentation is added both to the board introduction page and the
individual pins and functions.
The particle-{argon,boron,xenon} all have a uFL connector and a PCB
antenna for 2.4GHz radio, connected by a SKY13351-378LF switch
configured by a VCTL[12] pin pair.
This sets the default configuration to use the PCB antenna, as driving
an unconnected antenna will deteriorate radio performance.
The 'msba2' common files have accumulated many empty files are files that
do nothing.
This makes reasoning about the boards needlessly difficult.
Trim down on `common/msba2/` so that it now only contains the setup for the
UART/bootloader based flashing.
This should eventuelly be moved to `makefiles/tools/`
- Move serial.inc.mk in remote and openmote-b Makefile.include before
PROG_DEV to avoid repeating OS logic check
- Add deprecation warning for PORT_BSL
This is still currently a hack to hardcode it as the value can be deduced
from the `BOARD_MODULE` daughter board name.
But it requires more cleanup and could come in a separate step.
Part of moving CPU/CPU_MODEL definition to Makefile.features to have it
available before Makefile.include.
The board is deprecated, no need to ignore this board anymore here.
Having the `arduino` and `periph_pwm` features is now required for all
boards using 'arduino-atmega' (as it was except for that board).
If this should change in the future, it should be defined either in each
arduino board, in another board common, or per CPU_MODEL.
This change is for all boards with a sam0 cpu. This cpu just has one ADC.
It is unnecessary to have defines with ADC_0_ prefix as if multiple ADCs
are possible.
Some defines were not used, such as ADC_0_EN, ADC_0_CHANNELS,
ADC_MAX_CHANNELS, ADC_0_CLK_SOURCE, ADC_0_CHANNELS
Change all ADC_0_ prefixes to ADC_
- periph_conf_common.h contains peripherals configuration common to all mkr boards
- periph_conf.h is specific to a subset of mkr boards (mkr1000 and mkrzero)
