GNU LESSER GENERAL PUBLIC LICENSE |
||||||
|
Version 3, 29 June 2007 |
||||||
|
|
||||||
|
Copyright (C) 2007 Free Software Foundation, Inc. <http://fsf.org/> |
||||||
|
Everyone is permitted to copy and distribute verbatim copies |
||||||
|
of this license document, but changing it is not allowed. |
||||||
|
|
||||||
|
|
||||||
|
This version of the GNU Lesser General Public License incorporates |
||||||
|
the terms and conditions of version 3 of the GNU General Public |
||||||
|
License, supplemented by the additional permissions listed below. |
||||||
|
|
||||||
|
0. Additional Definitions. |
||||||
|
|
||||||
|
As used herein, "this License" refers to version 3 of the GNU Lesser |
||||||
|
General Public License, and the "GNU GPL" refers to version 3 of the GNU |
||||||
|
General Public License. |
||||||
|
|
||||||
|
"The Library" refers to a covered work governed by this License, |
||||||
|
other than an Application or a Combined Work as defined below. |
||||||
|
|
||||||
|
An "Application" is any work that makes use of an interface provided |
||||||
|
by the Library, but which is not otherwise based on the Library. |
||||||
|
Defining a subclass of a class defined by the Library is deemed a mode |
||||||
|
of using an interface provided by the Library. |
||||||
|
|
||||||
|
A "Combined Work" is a work produced by combining or linking an |
||||||
|
Application with the Library. The particular version of the Library |
||||||
|
with which the Combined Work was made is also called the "Linked |
||||||
|
Version". |
||||||
|
|
||||||
|
The "Minimal Corresponding Source" for a Combined Work means the |
||||||
|
Corresponding Source for the Combined Work, excluding any source code |
||||||
|
for portions of the Combined Work that, considered in isolation, are |
||||||
|
based on the Application, and not on the Linked Version. |
||||||
|
|
||||||
|
The "Corresponding Application Code" for a Combined Work means the |
||||||
|
object code and/or source code for the Application, including any data |
||||||
|
and utility programs needed for reproducing the Combined Work from the |
||||||
|
Application, but excluding the System Libraries of the Combined Work. |
||||||
|
|
||||||
|
1. Exception to Section 3 of the GNU GPL. |
||||||
|
|
||||||
|
You may convey a covered work under sections 3 and 4 of this License |
||||||
|
without being bound by section 3 of the GNU GPL. |
||||||
|
|
||||||
|
2. Conveying Modified Versions. |
||||||
|
|
||||||
|
If you modify a copy of the Library, and, in your modifications, a |
||||||
|
facility refers to a function or data to be supplied by an Application |
||||||
|
that uses the facility (other than as an argument passed when the |
||||||
|
facility is invoked), then you may convey a copy of the modified |
||||||
|
version: |
||||||
|
|
||||||
|
a) under this License, provided that you make a good faith effort to |
||||||
|
ensure that, in the event an Application does not supply the |
||||||
|
function or data, the facility still operates, and performs |
||||||
|
whatever part of its purpose remains meaningful, or |
||||||
|
|
||||||
|
b) under the GNU GPL, with none of the additional permissions of |
||||||
|
this License applicable to that copy. |
||||||
|
|
||||||
|
3. Object Code Incorporating Material from Library Header Files. |
||||||
|
|
||||||
|
The object code form of an Application may incorporate material from |
||||||
|
a header file that is part of the Library. You may convey such object |
||||||
|
code under terms of your choice, provided that, if the incorporated |
||||||
|
material is not limited to numerical parameters, data structure |
||||||
|
layouts and accessors, or small macros, inline functions and templates |
||||||
|
(ten or fewer lines in length), you do both of the following: |
||||||
|
|
||||||
|
a) Give prominent notice with each copy of the object code that the |
||||||
|
Library is used in it and that the Library and its use are |
||||||
|
covered by this License. |
||||||
|
|
||||||
|
b) Accompany the object code with a copy of the GNU GPL and this license |
||||||
|
document. |
||||||
|
|
||||||
|
4. Combined Works. |
||||||
|
|
||||||
|
You may convey a Combined Work under terms of your choice that, |
||||||
|
taken together, effectively do not restrict modification of the |
||||||
|
portions of the Library contained in the Combined Work and reverse |
||||||
|
engineering for debugging such modifications, if you also do each of |
||||||
|
the following: |
||||||
|
|
||||||
|
a) Give prominent notice with each copy of the Combined Work that |
||||||
|
the Library is used in it and that the Library and its use are |
||||||
|
covered by this License. |
||||||
|
|
||||||
|
b) Accompany the Combined Work with a copy of the GNU GPL and this license |
||||||
|
document. |
||||||
|
|
||||||
|
c) For a Combined Work that displays copyright notices during |
||||||
|
execution, include the copyright notice for the Library among |
||||||
|
these notices, as well as a reference directing the user to the |
||||||
|
copies of the GNU GPL and this license document. |
||||||
|
|
||||||
|
d) Do one of the following: |
||||||
|
|
||||||
|
0) Convey the Minimal Corresponding Source under the terms of this |
||||||
|
License, and the Corresponding Application Code in a form |
||||||
|
suitable for, and under terms that permit, the user to |
||||||
|
recombine or relink the Application with a modified version of |
||||||
|
the Linked Version to produce a modified Combined Work, in the |
||||||
|
manner specified by section 6 of the GNU GPL for conveying |
||||||
|
Corresponding Source. |
||||||
|
|
||||||
|
1) Use a suitable shared library mechanism for linking with the |
||||||
|
Library. A suitable mechanism is one that (a) uses at run time |
||||||
|
a copy of the Library already present on the user's computer |
||||||
|
system, and (b) will operate properly with a modified version |
||||||
|
of the Library that is interface-compatible with the Linked |
||||||
|
Version. |
||||||
|
|
||||||
|
e) Provide Installation Information, but only if you would otherwise |
||||||
|
be required to provide such information under section 6 of the |
||||||
|
GNU GPL, and only to the extent that such information is |
||||||
|
necessary to install and execute a modified version of the |
||||||
|
Combined Work produced by recombining or relinking the |
||||||
|
Application with a modified version of the Linked Version. (If |
||||||
|
you use option 4d0, the Installation Information must accompany |
||||||
|
the Minimal Corresponding Source and Corresponding Application |
||||||
|
Code. If you use option 4d1, you must provide the Installation |
||||||
|
Information in the manner specified by section 6 of the GNU GPL |
||||||
|
for conveying Corresponding Source.) |
||||||
|
|
||||||
|
5. Combined Libraries. |
||||||
|
|
||||||
|
You may place library facilities that are a work based on the |
||||||
|
Library side by side in a single library together with other library |
||||||
|
facilities that are not Applications and are not covered by this |
||||||
|
License, and convey such a combined library under terms of your |
||||||
|
choice, if you do both of the following: |
||||||
|
|
||||||
|
a) Accompany the combined library with a copy of the same work based |
||||||
|
on the Library, uncombined with any other library facilities, |
||||||
|
conveyed under the terms of this License. |
||||||
|
|
||||||
|
b) Give prominent notice with the combined library that part of it |
||||||
|
is a work based on the Library, and explaining where to find the |
||||||
|
accompanying uncombined form of the same work. |
||||||
|
|
||||||
|
6. Revised Versions of the GNU Lesser General Public License. |
||||||
|
|
||||||
|
The Free Software Foundation may publish revised and/or new versions |
||||||
|
of the GNU Lesser General Public License from time to time. Such new |
||||||
|
versions will be similar in spirit to the present version, but may |
||||||
|
differ in detail to address new problems or concerns. |
||||||
|
|
||||||
|
Each version is given a distinguishing version number. If the |
||||||
|
Library as you received it specifies that a certain numbered version |
||||||
|
of the GNU Lesser General Public License "or any later version" |
||||||
|
applies to it, you have the option of following the terms and |
||||||
|
conditions either of that published version or of any later version |
||||||
|
published by the Free Software Foundation. If the Library as you |
||||||
|
received it does not specify a version number of the GNU Lesser |
||||||
|
General Public License, you may choose any version of the GNU Lesser |
||||||
|
General Public License ever published by the Free Software Foundation. |
||||||
|
|
||||||
|
If the Library as you received it specifies that a proxy can decide |
||||||
|
whether future versions of the GNU Lesser General Public License shall |
||||||
|
apply, that proxy's public statement of acceptance of any version is |
||||||
|
permanent authorization for you to choose that version for the |
||||||
|
Library. |

Library of Infineon's highly sensitive [DPS310 sensor](https://www.infineon.com/cms/de/product/sensor/capacitive-pressure-sensor-for-consumer-applications/DPS310/productType.html?productType=5546d462525dbac4015312b96a743801) for Arduino. |
||||||
|
|
||||||
|
## Summary |
||||||
|
|
||||||
|
The [DPS310](https://www.infineon.com/dgdl/Infineon-DPS310-DS-v01_00-EN.pdf?fileId=5546d462576f34750157750826c42242) is a miniaturized digital barometric air pressure sensor with a high accuracy and a low current consumption, capable of measuring both pressure and temperature. The internal signal processor converts the output from the pressure and temperature sensor elements to 24 bit results. Each unit is individually calibrated, the calibration coefficients calculated during this process are stored in the calibration registers. The available raw data of the sensor can be calibrated by using the pre-calibrated coefficients as they are used in the application to convert the measurement results to high accuracy pressure and temperature values. |
||||||
|
|
||||||
|
Sensor measurements and calibration coefficients are available through the serial I2C or SPI interface. |
||||||
|
|
||||||
|

|
|
||||||
|
## Installation |
||||||
|
|
||||||
|
### Integration of Library |
||||||
|
|
||||||
|
Please download this repository from GitHub by clicking on the following field in the latest [release](https://github.com/Infineon/DPS310-Pressure-Sensor/releases) of this repository: |
||||||
|
|
||||||
|
 |
||||||
|
|
||||||
|
To install the DPS310 pressure sensor library in the Arduino IDE, please go now to **Sketch** > **Include Library** > **Add .ZIP Library...** in the Arduino IDE and navigate to the downloaded .ZIP file of this repository. The library will be installed in your Arduino sketch folder in libraries and you can select as well as include this one to your project under **Sketch** > **Include Library** > **DPS310**. |
||||||
|
|
||||||
|
 |
||||||
|
|
||||||
|
## Usage |
||||||
|
Please see the example sketches in the `/examples` directory in this library to learn more about the usage of the library. Especially, take care of the respective SPI and I²C configuration of the sensor. |
||||||
|
For more information, please consult the datasheet [here](https://www.infineon.com/dgdl/Infineon-DPS310-DS-v01_00-EN.pdf?fileId=5546d462576f34750157750826c42242). |
||||||
|
|
||||||
|
Currently, there exists the DPS310 Pressure Shield2Go evaluation board as a break out board: |
||||||
|
|
||||||
|
* [DPS310 Pressure Shield2Go](https://www.infineon.com/cms/de/product/evaluation-boards/s2go-pressure-dps310/) |
||||||
|
|
||||||
|
### DPS310 Pressure Shield2Go |
||||||
|
The DPS310 Pressure Shield2Go is a standalone break out board with Infineon's Shield2Go formfactor and pin out. You can connect it easily to any microcontroller of your choice which is Arduino compatible and has 3.3 V logic level (please note that the Arduino UNO has 5 V logic level and cannot be used without level shifting). |
||||||
|
Please consult the [wiki](https://github.com/Infineon/DPS310-Pressure-Sensor/wiki) for additional details about the board. |
||||||
|
|
||||||
|
Each sensor can only work either SPI or I2C. To convert from SPI to I2C, for example, you have to re-solder the resistors on the Shield2Go. Please take care that every Shield2Go for the DPS310 is shipped as I2C configuration right now. |
||||||
|
|
||||||
|
* [Link](https://github.com/Infineon/DPS310-Pressure-Sensor/wiki) to the wiki with more information |
||||||
|
|
||||||
|
However, every Shield2Go is directly compatible with Infineon's XMC2Go and the recommended quick start is to use an XMC2Go for evaluation. Therefore, please install (if not already done) also the [XMC-for-Arduino](https://github.com/Infineon/XMC-for-Arduino) implementation and choose afterwards **XMC1100 XMC2Go** from the **Tools**>**Board** menu in the Arduino IDE if working with this evaluation board. To use it, please plug the DPS310 Pressure Shield2Go onto the XMC2Go as shown below. |
||||||
|

||||||
|
|
||||||
|
## Known Issues |
||||||
|
|
||||||
|
### Temperature Measurement Issue |
||||||
|
There could be a problem with temperature measurement of the DPS310. If your DPS310 indicates a temperature around 60 °C although you expect around room temperature, e.g. 20 °C, please call the function correctTemp() as included in the library to fix this issue. |
||||||
|
|
||||||
|
In case you need additional help, please do not hesitate to open an issue in this repository. |
||||||
|
|
||||||
|
### Interrupt mode |
||||||
|
Interrupt mode not working reliably on XMC2Go for DPS310 right now. |
||||||
|
|
||||||
|
### Additional Information |
||||||
|
Please find the datasheet of the DPS310 [here](https://www.infineon.com/dgdl/Infineon-DPS310-DS-v01_00-EN.pdf?fileId=5546d462576f34750157750826c42242). It depends on the evaluation board which you are using or the respective configuration of the sensor on your PCB which communication protocol as well as addresses you need to use for communicating with the sensor. |
