Since IPHC also manipulates the total number of bytes of a received
datagram (by decompressing it), this also needs to be exposed. I guess
I was too focused on introducing a *generic* packet buffer for a future
virtual reassembly buffer (where it isn't needed, but so isn't `pkt` to
be honest), that I totally forgot about it in #9352.
- Added unit tests for new integer only arithmetic
- Temperature conversion differs at most 0.01°C from double arithmetic
- Humidity conversions differs at most 0.1% from double arithmetic
- Use RIOT's GPIO interface to access the sensor to increase portability
- Changed API to allow more than one sensor per board
- Added `sht1x_params.h` that specifies how the sensors is connected - each
board can overwrite default settings by #defining SHT1X_PARAM_CLK and
SHT1X_PARAM_DATA
- Changed arithmetic to use integer calculations only instead of floating point
arithmetic
- Added support for checking the CRC sum
- Allow optional skipping of the CRC check to speed up measuring
- Added support for advanced features like reducing the resolution and skipping
calibration to speed up measuring
- Allow specifying the supply voltage of sensor which heavily influences the
temperature result (and use that information to calculate the correct
temperature)
- Reset sensor on initialization to bring it in a well known state
- Support for the obscure heater feature. (Can be useful to check the
temperature sensor?)
- Updated old SHT11 shell commands to the new driver interface, thus allowing
more than one SHT10/11/15 sensor to be used
- Added new shell command to allow full configuration of all attached SHT1x
sensors
- Removed old command for setting the SHT11 temperature offset, as this feature
is implemented in the new configuration command
The sensor family SHT10, SHT11 and SHT15 only differ in their accuracy (as in
calibration, not as in resolution). Thus, the same driver can be used for all.
The new driver name better reflects this fact.
This refactors the `gnrc_sixlowpan_frag` module for the API proposed
in #8511.
The `ctx` for `gnrc_sixlowpan_frag_send()` is required to be a
`gnrc_sixlowpan_msg_frag_t` object, so IPHC can later on use it to
provide the *original* datagram size (otherwise, we would need to adapt
the API just for that, which seems to me as convoluted as this
proposal).
I also provide an expose function with a future possibility to provide
more than just one `gnrc_sixlowpan_msg_frag_t` object later on (plus
having cleaner module separation in general).
- This document is the result of original work by @haukepetersen and
refinement by @miri64, @aabadie, @kaspar030, @jcarrano,
@PeterKietzmann, @ZetaR60, and @jia200x.
When I introduced this pseudo-module in #9391 I did not consider, that
the way I named it, it is assumed to be an implementation of the
`gnrc_pktbuf` interface. However, it is not (it just provides the shell
command).
This PR excludes `gnrc_pktbuf_cmd` from the selection algorithm, so
that if it is the only `gnrc_pktbuf_%` module, still
`gnrc_pktbuf_static` gets selected.
