The I2C peripheral's shortcuts are used with the read and write register
to automatically stop the I2C transaction or to continue with the next
stage.
With simple I2C read and write bytes these shorts are not used, but are
also not cleared by the function in all cases, causing it to use the
shortcut configuration set by a previous function call. This patch
ensures that the shorts are always set by the read and write functions
The package uses the nRFx SDK package `nrfx`. In addition, the `mynewt-nimble` repository contains some files (`porting/nimble/src/hal_timer.c` and `porting/npl/riot/src/nrf5x_isr.c`) that are compilable only for nRF MCUs. To allow the compilation for other platforms, the use of the `nrfx` package and the compilation of these files are now dependent on the use of any nRF5x MCU.
These BLE_* features are not necessarily nRF5x specific and should be defined as common features. The commit also fixes the alphabetical order for HAS_RUST_TARGET.
This makes life easier when calling e.g. `saul_reg_write()` with data
stored in flash.
As now the signatures for reading and writing differ (in that `const`
qualifier only), `saul_notsup()` is split into `saul_write_notsup()`
and `saul_read_notsup()`. However, one is implemented as a symbol alias
of the other, so that ROM consumption remains unchanged.
Modify the periph_temperature implementation to expose the full
resolution of the temperature sensor. The accuracy of the sensor will
likely be less than 0.25 °C, but typically temperature sensors have
a precision in the order of their resolution. Exposing the full
resolution can therefore be useful to monitor relative temperature
changes.
The RTT overflow callback is not available on all RTT implementations.
This means it is either a no-op or `rtt_set_overflow_cb()` is a no-op
or it will overwrite the alarm set with `rtt_set_alarm()`.
This adds a feature to indicate that proper overflow reporting is available.
Some periph_rtt implementations do not provide `rtt_set_counter()`. This
adds `periph_rtt_set_counter` as feature to allow testing for its
availability. The feature is provided at CPU level if periph_rtt is
provided by the board for all CPUs implementing `rtt_set_counter()`.
