> -----------------------
>
> Key: MYNEWT-744
> URL: https://issues.apache.org/jira/browse/MYNEWT-744
> Project: Mynewt
> Issue Type: Improvement
> Security Level: Public(Viewable by anyone)
> Components: Drivers, Sensor Framework
> Reporter: Vipul Rahane
> Assignee: Vipul Rahane
> Fix For: v1_1_0_rel
>
>
> - Change data structure to SLIST instead of TAILQ so that it can get
> initialized statically. This is needed so that sysinit could be used for
> initializing the sensors.
> - Remove dummy functions in the bsp and add the sensor device initialization
> functions instead.
> - Adding syscfg based configuration for onboard Vs offboard sensors
> - Adding sensor creator package for creating external sensor devices if they
> are not on the board itself. This is just for convenience sake. The right way
> to do this would be from the bsp. As a result, removed sensor device creation
> from nrf52dk and nrf52840pdk bsps.
> - Add sensor interface struct so that it can get used by the individual
> drivers so that we can talk to multiple sensors using the same driver using
> same or different interfaces.
> - For TSL2561, apart from the above changes, various fixes were made:
> 1. Making a few changes to this driver along with sensor_itf changes
> 2. Gain, integration time and enabled flag was a global instead of
> reading every time gain is set or integration time is set. Changing it so
> that we read the timing register before setting either gain or integration
> time.
> 3. Also changing a few functions in the driver to handle errors more
> gracefully. Changing shell to work with new functions.
> 4. Making changes so that it goes in synch with the drivers.
> 5. Removing delays from the read function. the poller should be set
> according to the other config values being set so that the sensor is read at
> the correct interval.
> - Add a mask field to the sensor structure so that differentiating between
> supported Vs configured sensors is possible
> - Change the sensor_mgr_match_bytype() function to check w.r.t mask and make
> it a public API.
> - Adding config variable for mask for different drivers in their respective
> structures.
> - Adding an API to set the sensor types based on the mask.
> - Moving config_sensor() out of the app into the creator package and the bsp.
> Objective is to show how a developer would initialize and configure the
> sensor in the bsp which is normally the practice.
> - Changing sensor_shell command "list" to show only configured types.
> - sensor_shell cmd "type" shows supported types set by the driver.
> - In the sensor_oic source file changing code to check type only while
> allocating resources.
> - Changing device name in the sensors_test app to be "sensy" instead of "pi"
> - For the LSM303DLHC driver the address field in the "sensor_itf" structure
> is not enough since it talks to the sensor using two addresses: one for
> accelerometer and one for magnetometer. The best way to deal with this is to
> make the addresses config variables in the sensor driver structure. For any
> such sensor devices which have multiple addresses, a similar approach should
> be followed.
> - Have changed the drivers to work with all the fixes mentioned above.
