This adds the feature `periph_wdt_warning_period` that indicates that a
platform WDT driver implementation supports a configurable
CONFIG_WDT_WARNING_PERIOD.
The EDBG debugger on the `samr21-xpro` contains a unique 64 bit address
intended to be used as a MAC address for the internal radio.
This adds a driver to read that EUI-64 from the debugger, it should match
with the MAC address printed on the label on the board.
sdcard_spi is the only driver in auto_init_storage and was previously
pulled in by fatsfs (because it's used on SD cards)
It does however make much more sense if the SD card driver pulls that in
so other file systems can be used on SD card too.
The offset of MTD regions must be aligned with erase sectors.
So in order not to waste address space, avoid misconfiguration and
eventually support storage media > 4 GiB, give the offset in sectors
instead of bytes.
MRF24J40 supports a proprietary turbo mode with a data rate of 625 kbit/s
instead of the standard 250 kbit/s.
It can be enabled through
ifconfig 7 set high_rate 1
AT86RF2xx supports high data rates in O-QPSK mode.
This is a proprietary feature, so data rates > 0 are only supported by
other AT86RF2xx devices.
high_rate 0: 250 kbit/s (IEEE mode)
high_rate 1: 500 kbit/s
high_rate 2: 1000 kbit/s (compatible with at86rf215)
high_rate 3: 2000 kbit/s
It is often desireable to re-configure the pins of a bus back to GPIO mode,
either to save power when an external peripheral is turned off and current
would leak, or because a device may need a non-standard in-band signal to
be generated on the bus lines.
To serve those use cases, this patch introduces four new functions to the
I2C API:
- `i2c_init_pins()` equivalent to spi_init_pins(), restores I2C pin configuration
- `i2c_deinit_pins()` to switch the configuration of the I2C pins back to GPIO
mode and block access to the bus.
- `i2c_pin_sda()` to get the data pin for a given bus
- `i2c_pin_scl()` to get the clock pin for a given bus
Since it's unreasonable to expect having implementations for all platforms
already, those functions are only availiable when the periph_i2c_reconfigure
feature is availiable.
Applications should use FEATURES_REQUIRED += periph_i2c_reconfigure or
FEATURES_OPTIONAL if they want to make use of those functions.
