Hello Support,

just asking for TLE4942-1C any information about: 

MTTFd Rates (Years) 
diagnostic coverage (%) 

 Thank you 

Best regards,

Hello,

Regarding the datasheet, the mesurement range os the PAS CO2 is 0 to 32000ppm and the accuracy of 400-5000ppm is -30ppm-3%～+30ppm+3%.
Is it possible to show the accuracy under 400ppm because our customer would like to measure under 400ppm?

Best regards,
Nakamura

Hi, there

Just for your information, I posted a code sample for PSoC 4 (CY8CKIT-044)

Dear Customer,

we are happy to announce you the launch of our next generation of XENSIV™ Radar 24GHz DEMO kits with Sense2GoL Pulse and Distance2GoL.

Following the said launch, please be informed that these XENSIV™ Radar 24GHz demo kits are therefore discontinued: Sense2Go, Sense2GoL, Distance2Go and Position2Go.

We are transferring our support capabilities towards the new kits. For the discontinued kits, we will reduce and eventually stop our support including telephone, chat, community support forum, or e-mail inquiries. We apologize for any inconvenience caused.

Please find all needed information on all our 24GHz radar products and kits on www.infineon.com/24ghz.

Sincerely,
Your Infineon team

Hi @BenGBoo, 

Can you please let us know if you are looking for form factor compatibility? In that case, you are correct, the DEMO DISTANCE2GOL is Arduino header compatible whereas the DEMO BGT60LTR11AIP is Arduino MKR header compatible. The DISTANCE2GOL comes with an XMC 4700 baseboard that runs the Distance2GoL firmware.

Both these radar boards are 3.3 V compatible and can be used with an external microcontroller. These training videos should help with your query - 

DEMO DISTANCE2GOL 

DEMO BGT60LTR11AIP

Additionally, you can refer to the Distance2GoL (Software-Controlled FMCW radar) software user manual for information regarding the Distance2GoL firmware.

Please let me know if you have any further queries.

Hello,

I'm using the Position2Go board with the provided Matlab code. I've used the code to successfully transmit/receive one frame obtain a [fast-time x antennas x slow-time] cube using the function

oRS.oEPRadarBase.get_frame_data

(oRS being the RadarSystem object generated by the provided code).

I would like to know which parameter I need to change in the RadarSystem object or which function I need to call to transmit/receive multiple frames, so to obtain a [fast-time x antennas x slow-time x frames] 4-dimensional array.

So far my initialization code is the following, with parameters from an external global structure "p" (p.fs, p.N, p.Ns, p.B_kHz, ...) :

% Create radar system object
szPort = findRSPort; % find the right COM Port
oRS = RadarSystem(szPort); % creates the Radarsystem API object

% Set endpoint properties
% The automatic trigger runs after startup by default
oRS.oEPRadarADCXMC.samplerate_Hz = p.fs; % updates the chirp duration oRS.oEPRadarBase.chirp_duration_ns (upchirp time)
oRS.oEPRadarBase.stop_automatic_frame_trigger;      % stop it to change values
%oRS.oEPRadarBase.set_automatic_frame_trigger(1000000);
oRS.oEPRadarFMCW.lower_frequency_kHz = 24.025e9 / 1000;    % lower FMCW frequency
oRS.oEPRadarFMCW.upper_frequency_kHz = oRS.oEPRadarFMCW.lower_frequency_kHz + p.B_kHz;    % upper FMCW frequency
oRS.oEPRadarFMCW.tx_power = oRS.oEPRadarBase.max_tx_power; % or put an integer value between [0,7], 0 being the lowest power level and 7 the highest
oRS.oEPRadarP2G.pga_level_val = 0; % put an integer value between [0,7], 0 being the lowest power level and 7 the highest
oRS.oEPRadarBase.num_chirps_per_frame = p.N;
oRS.oEPRadarBase.num_samples_per_chirp = p.Ns;       % % updates the chirp duration oRS.oEPRadarBase.chirp_duration_ns (upchirp time). Ns up to 4095 for single RX channel
oRS.oEPRadarBase.rx_mask = bin2dec('0011');         % enable RX1 & RX2 antenna
oRS.oEPRadarFMCW.direction = 'Up Only';

Thank you for your help! Show Less

Hi everyone,

I am working with the demo board Position2Go. I have successfully used the C Communication Library provided by Infineon on my Windows machine to stream the data from the board to my PC.
Now I am trying to make it work on my Ubuntu 16.04 machine, however, I have encountered some difficulties. When I run the script 'extract_raw_data.c' (without compile errors) it looks like my machine is unable to open the device for communication.
In particular, the function 'open()' used in the file COMPort_Unix.c returns -1. In the same file, the variable 'port_name' contains the correct location and name of the device: "/dev/serial/by-id/usb-Infineon_IFX_CDC-if00".
I would like to add that I have not installed any Infineon related software or driver on my Ubuntu machine.
Has anyone encountered a similar problem? What advice can you give? Any help is appreciated. I can provide additional details if necessary.

Thank you very much in advance. Show Less

Hello Infineon Community,

I have 3 queries namely:

1. Using the Matlab interface provided, I managed to capture the speed graph of my target as shown below. Is there any way to show the Fastest Speed, Slowest Speed, Average Speed of this graph? Any Matlab Code/Function that I can use for this?


2. Also, is there any way I can get the graph to display as a function of time instead of frames? From my understanding, my frames interval is left default at 150ms, does this means that there are 6.66 frames per second?

3. Is there any way for me to capture the time and coordinates (distance, degree)? The reason is that I would like to measure the distance my target travelled, so that I can find out the average speed of my target. Alternatively, is there any way I can measure the distance travelled and the average speed of my target?

Any pointers will be much appreciated. Thank you! 🙂 Show Less
