Pressure Sensors

Our XENSIV™ family of digital absolute barometric pressure sensors gives designers the best choice when it comes to mobile and wearable devices. Highlights include small form factors to facilitate system integration, highest precision and relative accuracy over a wide temperature range, fast read-out speeds via the serial I2C/SPI interface, and low power consumption to ensure longer battery lifetimes. All of our air sensing solutions have a FIFO buffer that can store the last 32 measurements. Since the host processor can remain in sleep mode for a longer period between readouts, the FIFO buffer can reduce system power consumption further.

Speed (Magnetic sensor)

In this forum you can post your questions, comments and feedback about the XENSIV™ Speed sensors. This sensor family is based on integrated Magneto Resistive (ixMR) or hall-based technologies in order to determine linear and rotational speed. Our Speed sensors can be used with ferromagnetic gear tooth wheels or encoders to measure speed and position and they are essential components for the function of safety and powertrain applications like rotating shafts. Here you can also find the links to the latest board pages, documents and FAQs.

I am running into issue when linking the xensiv-radar-presence static library (link to github repo). For context, I am using an STMF407G Discovery board with the DEMO BGT60TR13C. I am trying to port GitHub - Infineon/mtb-example-psoc6-radar-presence example to the STM32 board. I am using these drivers GitHub - Infineon/sensor-xensiv-bgt60trxx

At the bottom of this post are the error messages from the console during linking.

All the errors indicate something is wrong with the CMSIS DSP library. I am fairly certain that the CMSIS library is properly setup because the sensor dsp library (sensor-dsp/include at master · Infineon/sensor-dsp · GitHub) is able to access arm_math.h without any errors.

Please let me know what I can do to resolve this linking issue. The source code is not provided on github which makes it more difficult to debug.
