RoadTest: MyIoT: Infineon Shield2Go Boards for IoT

Author: himanshu_rangadhol

Creation date:

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?: Launch XL RM42 ti board ( ARM M0), ARDUINO NANO( as I was coding mostly on Arduino IDE it was comparable for most of the results with these Infineon boards)

What were the biggest problems encountered?: 1. The header pins were big hassle to work with. Took sometime to figure out how they fit in!(The female header pins won't fit into any of the boards). 2. XMC1100 2Go board was getting heated up pretty badly at times!

Detailed Review:



First of all huge thanks to element14 and Randall Scasny for providing this great opportunity. I received the package bit late due to some confusion, never the less the boards reached safely and well packed.

Working with Arduino IDE


Most of the time I prefer to work with Arduino IDE as it is easy to test the product in the initial stages. The advantages with Arduino IDE is

1. Embedded Coding is very simple.

2. has huge community behind for any kind of support.
3. Comparing with Arduino Boards is easy.


The first thing as anyone would do I connected the XMC boot kit to my laptop using a USB cable. Guess what it didn't work. Best part was at the bottom of roadtest page they have given a GitHub link for software libraries and Arduino IDE, it helped alot!. link for all the boards


This GitHub page has almost everything we need to start working with XMC boards.  link for adding library for arduino IDE for XMC boards ( includes all the boards in XMC series)


If you follow step by step according to the page this is the last step before getting started to set up the environment for infineon boards in Arduino IDE.


Adding Arduino Library

I wrote a simple program and it compiled without any error! but when I tried to upload the code I got an error! went back to the GitHub page and checked I had forgotten to add the J-link library. As I am used to Arduino IDE first thing I did was to check whether the board is recognized in the COM ports and it was recognized. So this error took me back to the GitHub page.


So after installing the J-link libraries I was able to upload the code into the XMC boards.


Now though the boot kit is compatible with Arduino shields the pins are completely different than to the Arduino Uno board (Except the power pins). So next two images are quite important if you want to code for these boards on Arduino IDE. They have almost all the data and well put out diagram without raising further confusions.





General Blink and Serial Debugging Test


As the XMC1100 has 6 user definable general purpose LEDs on the board it self, its quite interesting and fun way to start exploring the board.


Example code for bootkit :(FOR BEGINNERS)










int led1 = 26;    //this pins are defined in the PO released by infineon

int led2 = 27;

int led3 = 0;

int led4 = 1;

int led5 = 2;

int led6 = 31;



void setup() {

  // initialize  6 LED pins as an output.

  pinMode(led1, OUTPUT);

  pinMode(led2, OUTPUT);

  pinMode(led3, OUTPUT);

  pinMode(led4, OUTPUT);

  pinMode(led5, OUTPUT);

  pinMode(led6, OUTPUT);



// the loop function runs over and over again forever

void loop() {

  digitalWrite(led1, HIGH);


  digitalWrite(led1, LOW); 


  digitalWrite(led2, HIGH);


  digitalWrite(led2, LOW);


  digitalWrite(led3, HIGH);


  digitalWrite(led3, LOW);


   digitalWrite(led4, HIGH);


  digitalWrite(led4, LOW); 


  digitalWrite(led5, HIGH);


  digitalWrite(led5, LOW);


  digitalWrite(led6, HIGH);


  digitalWrite(led6, LOW);




XMC1100 2Go has only two user definable LEDs. So you will get the pins for arduino on PO for XMC2Go.


All the required data sheets and other details are available on Infineon website.

Serial Debugging


Shields Interfacing:

The initial problem was to find the right female header pins for the XMC2Go as the default sent pins were no where closer to fit in the board. Already a predefined library is available on GitHub for these sensors for the Arduino IDE.


DPS310 Pressure Shield2Go


GitHub Link:

Other link:  (I didn't try this library, just found this when i was searching for Arduino libraries)


The DPS310 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 coeȄicients calculated during this process are stored in the calibration registers. The coeȄicients are used in the application to convert the measurement results to high accuracy pressure and temperature values. Sensor measurements and calibration coeȄicients are available through the serial I2C or SPI interface.


Key Features:

  • Operation range: Pressure: 300 –1200 hPa. Temperature: -40 – 85 °C.
  • Pressure sensor precision: ± 0.005 hPa (or ±0.05 m) (high precision mode).
  • Relative accuracy: ± 0.06 hPa (or ±0.5 m)
  • Absolute accuracy: ± 1 hPa (or ±8 m)
  • Temperature accuracy: ± 0.5°C.
  • Pressure temperature sensitivity: 0.5Pa/K
  • Measurement time: Typical: 27.6 ms for standard mode (16x). Minimum: 3.6 ms for low precision mode.
  • Average current consumption: 1.7 µA for Pressure Measurement, 1.5uA for Temperature measurement @1Hz sampling rate, Standby: 0.5 µA.
  • Interface: I2C and SPI (both with optional interrupt)


This initially gave multiple issues, but later worked precisely.


TVL493D 3DSense Shield2Go


GitHub Link:


The 3D magnetic sensor TLV493D-A1B6 offers accurate three-dimensional sensing with extremely low power consumption in a small 6-pin package. With its magnetic field detection in x, y, and z-direction the sensor reliably measures three-dimensional, linear and rotation movements. Applications include joysticks, control elements (white goods, multifunction knops), or electric meters (anti tampering) and any other application that requires accurate angular measurements or low power consumptions. The integrated temperature sensor can furthermore be used for plausibility checks.

Key features are 3D magnetic sensing with a very low power consumption during operations. The sensor has a digital output via 2-wire based standard I2C interface up to 1 MBit/sec and 12 bit data resolution for each measurement direction (Bx, By and Bz linear field measurement up to +-130mT).


Key Features:

  • Integrated temperature sensing
  • Low current consumption of 0.007 µA in power down mode and 10 µA in ultra low power mode
  • 2.7 to 3.5 V operating supply voltage
  • Digital output via 2-wire standard I2C interface
  • Bx, By and Bz linear field measurement up to ±130 mT
  • 12-bit data resolution for each measurement direction
  • Resolution 98 µT/LSB
  • Operating temperature range from -40 °C to 125 °C
  • GUI for free download as well as integration in Arduino IDE with this repository


TLI4970 Current Sense Shield2Go

GitHub Link:


The TLI4970 is a high-precision current sensor based on Infineon's proven Hall technology. The coreless concept significantly reduces footprint compared with existing solutions. TLI4970 is an easy-to-use, fully digital solution that does not require external calibration or additional parts such as A/D converters, 0 pAmps or reference voltage. It thus significantly reduces overall implementation efforts as well as PCB space and cost.


Key features:

  • AC & DC measurement range up to ±50A
  • Highly accurate over temperature range and lifetime (max. 1.0% (0 h),
  • 1.6% (over lifetime) of indicated value)
  • Low offset error (max. 25mA)
  • High magnetic stray field suppression
  • Fast overcurrent detection with configurable threshold
  • Galvanic isolation up to 2.5kV max. rated isolation voltage (UL1577)
  • 16 bit digital SPI output (13 bit current value)
  • Small 7 mm x 7 mm SMD package
  • GUI for free download as well as integration in Arduino IDE with this repository


I interfaced a flex sensor to the this current sensor and the results were phenomenon. Advantages were

1. One of my ADC pin was free now.

2. No fear of damaging the board because of high current variation caused by the flex sensor (As the resistance varies enormously in flex sensor)

3. Very accurate data.


Precautions: Make sure the current sensor is along with the path of the flex sensor and don't use the voltage divider circuit as used in traditional method)



Apart from providing the WLAN communication for the XMC1100 boards i didnt find any other special usage for this roadtest. Though ESP8266 is a powerfull and widely used MCU for IoT porjects, for this road test most of my concentration was on XMC boards.


Future Plans and conclusion


As I am still exploring these boards, I would love to implement these into my research projects and test out the capabilities with respect to PWM, ADC and higher data latency for further communications.


These are pretty rugged and versatile boards. only problem I faced was connecting through those header pins. Also XMC2Go1100 board was getting heated up pretty badly. The main advantage i found is compatibility of these boards with arduino IDE which is a great thing! I am still exploring the i2c and spi protocols, so in future i will be uploading more data on this.


I am doing research on tracking the Gross motor actions for special children using frugal science ( the exoskeleton is built using bamboo, for sensing I am using pot, rotary encoders and flex sensor. Basically consuming most of time in understanding and mapping these results to form a standard deducible structure for every action of special children.) So in future I will be uploading these research data.


I am delighted to be a part of this roadtest and there is still plenty more to explore. Surely I will be uploading more data regarding these boards in future.
