Evaluation Type: Development Boards & Tools

Did you receive all parts the manufacturer stated would be included in the package?: True

What other parts do you consider comparable to this product?: compare DPS310 with TE-Connectivity’s MS5637 digital barometric pressure sensor and NXP MPL3115A2 precision pressure sensor with altimetry

What were the biggest problems encountered?: Lack of full compatibility with arduino boards due to voltage levels restrictions; Lack of documentation of "Adapter Board"; initially - instability of magnetic sensor - my fault/ misunderstanding, at last, the magnetic board worked fine! ... My fear of ESD

Detailed Review:

Introduction

Quoting Infineon - “Customers can now develop their own system solutions by combining Shield2Go boards together with Infineon My IoT adapters.

My IoT adapters are gateways to external hardware solutions like Arduino and Raspberry PI, which are popular IoT evaluation platforms.

All this enables the fastest evaluation and development of IoT system on the market!.

After relative long tests I must agree and confirm specially compatibility with arduino software.

The set enriched with communication board made tested sensor board really IoT equipment.

Unboxing

Having difficulties with idea how the introduction to the next fascinating roadtest should looks like, I decided to go traditionally, starting from obviously obligatory but simple and quick unboxing record and "first impression".

Moreover completing my report I decided to show in the first chapter also assembly results.

I got five products by  Infineon: two XMC1100 development boards, three sensor boards and one “mysterious” (finding the documentation is tricky) adapter board

and last, not least - WiFi board (also undefined in roadtest specification)

Everything came well packed and secured. Infineon’s boards have been delivered in nice boxes, WEMOS WiFi and Adapter board in ESD bags.

I must also mention the set of sockets and pins. Sensor boards were accompanied  with SIP pins. The most interesting solution regarding included sockets, are solderless connectors.

Below: Shield2Go Boards: current, magnetic and pressure

 

 

 

in order to use the arduino compatible boards with XMC1100, I had to solder the terminals

 

24V Protected Switch Shield

 

You can see, there are extra terminals available (beyond classic Arduino design)

XMC1100 ready

 

XMC1100 Boot Kit after montage

 

 

 

“Hardware setup” od XMC 2GO board I decided to use own long (too long) tail  sockets.

That made the board more flexible for prototyping works.

I just wanted to copy the solution from WEMOS wiFi board - which was accompanied with sockets with long tails - you can see it below:

 

 

 

 

The magnetic sensor with 2GO development board stacked together - below:

 

 

Here we have very interesting proposal for prototyping - adapter board.

 

On the picture below you can see solderles sockets inserted to the board. The solution made the board preparation quick and easy.

I wonder of reliability of connections after long time of exploitation. For now I have no remarks.

 

Assembly conclusions. Some insertion force is necessary! As usual with sockets- cutting require precision and carry.

There is risk of broke pins/ sockets near the cutting point. therefore, the manufacturer could provide longer sockets sections - I would feel more comfortable.

 

Below: both solder and solderless technology used to complete the board

ESD issue

I feel obliged to share my fears of ESD

All boards are signed as ESF fragile, however amateur tests even in good prepared laboratory have risk of electrostatic... consider - cold evenings in this autumn and my favourite fleece blouse...

Fortunately, there were no accident, so far.

 

 

 

Let me give  short review of equipment parameters and features. Below  I’ve prepared overview of available documentation and online support. Let’s treat it as introduction into the realm of Infineon controllers.

Current sensor board TLI4970

S2Go_CurrentSenseTLI4970: evaluation boards are equipped with one TLI4970 current sensor and come with a ready to use Arduino library.

TLI4970 Description: TLI4970 is a high-precision current sensor based on Infineon´s proven Hall technology.

Infineon is proud of their coreless magnetic current sensor concept.

The output signal is highly linear and without hysteresis. However, a differential measurement principle allows effective stray field suppression.

Due to the integrated primary conductor (current rail) and  fully digital solution there is no need for external calibration or additional parts such as A/D converters, 0 pAmps or reference voltage.

Additionally, a separate interface pin (OCD) provides a fast output signal in case a current exceeds a pre-set threshold. The coreless concept significantly reduces footprint compared with existing solutions.

"The adapter"

Looks quite advanced and comprehensive But I was lost trying to acquire some information about it…

well I noticed that our board is available in extended XMS2Go kit where it is named Triple-Adapter – Adapter for Infineon Shield2Go

with Arduino-Uno Formfactor (alternatively: Grove Base_Shield_V2)Its catalogue name is MYIOTADAPTERTOBO1

I even find the ordering number: B138-I0613-V1-7600-EU-EC-PNevertheless, unfortunately, the only paper I found is:

Infineon-S2Go_MyIoT_Fast_flexible_and_easy_prototyping_for_ IoT-ABR-v01_00-EN.pdf

It looks fine but I miss more detailed schematic etc…

I decided to ask for documentation or same info about the board on the forum:https://www.infineonforums.com/threads/6180-MyIoT-adapter-board

 

 

And at Technical Assistance Center (TAC):https://www.infineon.com/cms/en/about-infineon/company/contacts/product-support-form/?redirId=56193

I asked for  providing me with detailed documentation of fast prototyping "MyIoT adapter board" particuliary about "I2c bridge" and possible SPI level converter (2 chips upper right part...

“How to prepare/ set-up  the adapter to avoid overvoltage of inserted 2Go boards.Is it possible to use all three "banks" of 2Go shields... etc

In that case making reverse engineering of your adapter seems to be nonsense.on the other hand, without complete documentation

the board is uselessHoping, you can help me with understanding the MyIoT adapter”

Unfortunately my questions remained unanswered:

 

One more source of documentation -

Users forum

As mentioned above - In addition to extensive documentation, Infineon provides convenient users forum.

https://www.infineonforums.com/https://www.element14.com/community/external-link.jspa?url=https%3A%2F%2Fwww.infineonforums.com%2F

Maybe the example with the mysterious board is unlucky but I must confirm the forum is excellent way to get quickly the answer concerning Infineon products, software etc!

 

Remarks concerning documentation

Apart “Adapter Board” issue - regarding documentation, I found it very clear and informative.

Installation of SEGGER\ JLink

In order to use and program the Infineon XMC 1100 in the Arduino IDE, SEGGER J-Link must be installed on the PC.

J-Link

Segger provides extensive J-Link control panel reach in features and informations:

 

 

Firmware update after first power on

After installation of Jlink, the integration goes smooth

Important subject is software used during tests.

In the roadtest I used both

DAVE & Arduino IDE

 

Arduino ide

I hope only short description of Arduino world is necessary, as it is obviously well known programming environment.

“Arduino is an open-source electronics platform based on easy-to-use hardware and software. Arduino boards are able to read inputs - light on a sensor,

a finger on a button, or a Twitter message - and turn it into an output - activating a motor, turning on an LED, publishing something online.

You can tell your board what to do by sending a set of instructions to the microcontroller on the board.

To do so you use the Arduino programming language (based on Wiring), and the Arduino Software (IDE), based on Processing. “

 

https://www.arduino.cc/en/Tutorial/HomePagehttps://www.arduino.cc/en/Main/FAQ

Well described, with fantastic support and user forumshttps://forum.arduino.cc/

 

 

What can I add? - I discovered, that Shield2Go adaptershave  repositories on Infineon GitHub.

All of them are compatible with Arduino library - which made my tests faster (no need for digging for documentation losing time on knowledge path etc.)

I sincerely recommend it to all infineon boards users!

Infineon's XMC support for Arduino

The most convenient way is to use GitHub Infineon repositories and proceed according to instructions.

https://github.com/Infineon/XMC-for-Arduinohttps://www.element14.com/community/external-link.jspa?url=https%3A%2F%2Fgithub.com%2FInfineon%2FXMC-for-Arduino

Settings in board manager is necessary but simple indeed!

DAVE

Thanks to my previous Infinoen boards roadtest, I know The DAVE environment.It is quite complex and sophisticated programming suite.

Thanks to the well prepared manuals,  installation of DAVE is quite simple.https://www.infineon.com/cms/de/product/microcontroller/32-bit-industrial-microcontroller-based-on-arm-cortex-m/32-bit-x…

DAVE is free Eclipse based IDE using GNU C-compiler for XMC microcontrollers.

According to Infineons it is application oriented code repository merged with graphical system design methodsand automatic code generator to guide microcontroller useralong the entire process – from evaluation-to-production (E2P).

Infineon provides also example projects for DAVE™ Apps:https://www.infineon.com/cms/en/product/promopages/aim-mc/dave_downloads.html

Using documentation and above examples I've realized that Dave environment is "programmer friendly"It truly exceeded arduino IDE functionality.

On the other hand as many eclipse environment it demands huge disc space. Installation takes significant time.The only doubt was the problem with J-Link driver installation.

According to papers and installation noticesthe driver should be installed together with DAVE.

Maybe I didn’t check appropriate box in menu during the process but finally I had to install it separately

Infineon Designer

Another outstanding support from Infineon is Infineon Designer

The online prototyping engine combining analog and digital simulation functionalities in an internet application.

It is available via web browser, neither installation nor licenses are needed.

  • Need of “tuning” of code

Using the raw version I encountered some troubles compiling arduino codes

Errors in example: analogwritetest.ino

* Test analogwrite functions for any board */

error: missing binary operator before token "1100"

Simple corrections in arduino.h files

 

 

Ather these simple modifications the program works well

 

 

DPS310 sensor tests

After soldering pins the board was ready for manipulation with evaluation boards. Honestly, after readinf this:

 

Warning

The DPS310 has a maximum rating of  4 V

• Third party boards with 5 V logic, e.g. the Arduino Uno, cannot be connected to the DPS310 Pressure Shield2Go board directly,

   even if the power is connected to the 3.3 V pin as the interface lines, e.g. SDA/SCL, will still be driven by 5 V

• Please use appropriate level shifting for these boards

 

I decided to work only with delivered Infineon development environment (XMC boards) as well as WEMOS card.

Nevertheless using simple 5/3V level converter usage with arduino boards is safe.

Another remark regards selection of interface:

Standard delivery of the board in terms of interface

mode is I²C with 0x77 when the 0 Ohm resistors

are soldered as shown on the right picture

I left I2C as the easier and convenient solution.

 

I started looking at papers and examples available on GitHub

 

 

https://github.com/Infineon/DPS310-Pressure-Sensor

Installation

Integration of Library

Please download this repository from GitHub by clicking on the following field in the latest release of this repository or directly here:

 

 

 

 

You can find the necessary library in “Arduino Library List“ https://www.arduinolibraries.info/libraries/dps310

 

The setup is simple and very intuitive indeed!

Install Library

The first running code:

Readout of pressure, temperature and sending it via UART:

 

Using DAVE I have adopted simple codes for  DPS310 originally dedicated to arduino, from github

 

 

Despite sensors are described as arduino - compatible I hoped to use it also with Raspberry Pi.

I planed to use pressure DPS310 transducer in both weather and altitude applications.

Here are examples of my attempt to catch readouts using Thing Speak cloud - fine platform for presentation of IoT data.

First I tried to use the DPS310 sensor with my Raspberry, which works as the motherboard of the simple weather station.

I have good "sense" in weather station matters, as I have home built  RPi based W-S with both local and cloud based data logging system.

I decided  to compare DPS310 with TE-Connectivity’s  MS5637 digital barometric pressure sensor which I know using T-E Weather Shield.

weather temp sensor

 

Unfortunately I fail with python codes and finally the only success was localisation of I2C address of the DPS310 sensor:

 

I did not give up however.

The next turn was employment of WEMOS wiFi board to have chance to send sensors data into the world.

 

 

 

WEMOS tests

All you need is available in the net:

Lets Establish a Wi-Fi connection

My first code let me control onboard LED using html command within local network:

 

 

The situation could be monitored using terminal:

 

WEMOS+ DPS 310 & Thingspeak

Then I decided to combine my both achievements DPS310 and WEMOS

Thingspeak

I tried to open  private Thingspeak channel with an ESP8266 and fill with sensor data.

I found Thingspeak / 8266 library for Arduino. It comes with convenient examples.

 

 

 

 

Some tests with generation of dummy data

DPS 310 pressure diagram:

And the comparison of both sensors

 

 

 

Despite the difference (parallel shift only) , accordance of above charts is impressive!

 

 

Additional chart: comparison of temperatures:

Unfortunately DPS310 gives integers only, without decimals.

 

 

 

According to available papers and articles,DPS310 is recommended thanks to guaranteeing high precision and excellent stability across temperature changes.

My short test programm confirms that. The sensor is immune for various environment conditions as temperature.

I’m also satisfied with the speed of readouts as well as general stability of DPS310.

TLV493D  sensor tests

Like previously discussed DPS310, TLV493D is supported with graceful package of arduino library and examples.

Appropriate links are on the official Infineon’s datasheets.

Moreover the TLV493D simulation project is available.

And first observations:

The readouts are horrific unstable!

Spherical

Fluctuations are visible on video:

I did not give up and I kept going despite the bad results.

Together with “ino” example for arduino and ready to use libraries, dedicated for our sensor, I found examples of codes for “PROCESSING”

Most of these examples use SphericalFast.ino

 

Example screen of working “processing” project - below

 

 

 

 

I dreamed of space mission:

But I got lost in space…

 

Then I realized, that earth magnetic field is weak to activate the sensor - in different way, It isn’t sensitive enough to work as geomagnetic sensor.

We need the magnet to conduct successful experiments As follow:

 

Infineon prepared one more tool for quick evaluation of the sensor:

Soft Evaluation Kit for 3D Magnetic Sensor

It Downloads the firmware into xms2GO

 

 

Printables - During my experiments I realized, that something new appeared on GIT:

The TLx493D 3D magnetic sensor family has additional tools which can be directly mounted on top of the evaluation boards.

The 3D print data of the joystick can be found in the folder printables/joystick.

Also, The extended “GET START BOX IOT” kit consist of these convenient tools:

 

 

OTHER:

I plan to connect that board with Raspberry

So far I have only recognized the I2c line… to be continued...

 

 

 

TLI4970 sensor tests

Analogously to previous boards - I got ready to use arduino library as well as examples

Results of the simple code:

 

Max = 0.1  min = -0.11

Not bad!

 

 

Conclusions

Infineons Shield2Go boards guarantee precise and easy operation for designer.

Multiplicity of examples allow for easy start with the set of sensors.

My research confirmed the flexibility of DAVE programmer suite although, use of simple Arduino IDE is definitely more convenient and - specially with small projects - simpler.

 

 

One of the important and widely  advertised feature of kit is availability of solderless connectors. I checked and confirm benefits. As far  reliability and immunity of that solution looks irreproachable.

 

As quoted at the beginning:

“My IoT adapters are gateways to external hardware solutions like Arduino and Raspberry PI” -> hard to deny, nevertheless I had difficulties with employment of our boards to work with Raspberry

(My fault I agree but also support is unavailable yet). Another issue concerns voltage levels

For this reason I did’t experiment with arduino boards using these sensors!

 

 

Product Performed to Expectations

  • lack of full compatibility with arduino boards due to voltage levels restrictions

Specifications were sufficient to design with

  • Lack of documentation of Adapter board

Demo Software was of good quality

  • YES YES YES OF COURSE!

Product was easy to use

  • YES OF COURSE!

Support was available

  • YES but we fail with that adapter board...

The price to performance ratio was good

  • Hard to say, sorry!
