Raw Normal View History

sensor_combined cleanup: remove many unneeded fields Decreases the message size from 780 to 280 bytes. In particular, all modules using sensor_combined must use the integral now. The sensor value can easily be reconstructed by dividing with dt. Voters now need to be moved into sensors module, because error count and priority is removed from the topic. Any module that requires additional data from a sensor can subscribe to the raw sensor topics. At two places, values are set to zero instead of subscribing to the raw sensors (with the assumption that no one reads them): - mavlink mavlink_highres_imu_t::abs_pressure - sdlog2: sensor temperatures

# Sensor readings in SI-unit form.
# These fields are scaled and offset-compensated where possible and do not
# change with board revisions and sensor updates.
Move more messages to auto-generation, work on C++ code style

int32 RELATIVE_TIMESTAMP_INVALID = 2147483647 # (0x7fffffff) If one of the relative timestamps is set to this value, it means the associated sensor values are invalid
sensor_combined: replace accel & gyro integral with value, use float for dt Reason: the value is easier to read & handle (for example plotting). In most places the value is needed, not the integral. Note that this breaks the replay format for sdlog2 replay

sensors: move voting into sensors module - voting is now at a central place instead of duplicated within the estimators -> this also means that estimators that did not do voting so far, now have voting, like ekf2 - estimators requiring more than that can still subscribe to the raw sensors - allows sensors_combined to be 3 times smaller - reduces logger, memcpy (cache) & RAM overhead - all modules requiring only 1 or 2 sensor values now automatically get the voted result - this also adds voting to baro
