Applications and tools
Acconeer Exploration Tool consists of a set of tools and examples to help you get started with our Evaluation Kits (EVK). With a graphical interface for your PC and python-based development, it allows you to quickly start exploring the world of Acconeer’s radar sensor technology.
You can download an executable version of Exploration Tool for Windows, or get the full version in our Exploration Tool repo on GitHub. The full version supports Linux and Windows.
Additional tools and example applications
In addition to Exploration Tool, we provide several example applications and other tools on the Acconeer GitHub page. These are frequently updated and new assets are added all the time, so head over to GitHub to find out more.
Example Android Applications
We have developed a few examples of how to control our sensor fron an Android Application and utilize a few basic use cases.
We do not plan to maintain or develop these further but you are free to download and use them.
FAQ
On this page you find some of the most common questions we receive from customers during their development and integration. If you can’t find the answer you need here, submit a ticket to us!
HW
The frequency of the crystal oscillator connected to A111 is specified between 20-80MHz. It must be at least 20.625MHz in order for the SPI frequency to reach 50MHz which is necessary in order to obtain the 1500Hz update rate.
The main purpose of having a range for the input frequency on XIN between 20MHz and 80 MHz is to allow for a flexible hardware integration. It allows the customer to choose a crystal oscillator more freely and an already existing reference clock in the design could be reused for the A111. It must however be ensured that the crystal or the reference clock that is to be used fulfils the requirements stated in the datasheet.
The use of a crystal oscillator or reference clock with higher frequency could benefit the accuracy of the sensor measurement if the relative increase in phase noise is smaller or equal to the relative increase in frequency. The use of a crystal oscillator or reference clock with higher frequency will however increase the power consumption of the A111.
SW
Acconeer have extended support for STM32L476 (ST-Micro) and STMCubeIDE.
Any MCU based on ARM CM0, CM4 and CM7 can be used by downloading the corresponding SDK and by implementing the HAL layer as described in the HAL SW Integration User Guide.
Accessing A111 registers via the SPI interface is not supported. The main reason is that to make changes to the registers, one must have knowledge about proprietary design details which are confidential. The performance of the sensor also depends on nontrivial calibration and signal processing software that is included in the software libraries.
The sensor is controlled using the Software API “Radar Services” and all settings are done using this API. A description of how to change the settings as well as a description of the radar data provided by the different services is documented in the user guides that are available on the Acconeer webpage.
No, you can use open source software such as gdb and openocd.
This is the direct leakage caused by TX leaking over to RX directly without bouncing on a real object. Increasing the start range solves the problem.
QUESTION: Test result after S/W Compile shows reaching distance no further than 40cm. It is normal or do we expet to see up to 2m?
ANSWER: This is as expected, the test program you are running is probably set to measure up to 40cm. To make other measurements you include other input parameters in the Distancestrongest API. For guidance please look at API user manual, found in doc/html,with index file, when extracting SW zip file to a new directory.
