I am now using the ESP32 to stream the raw radar data from  XENSIV™ BGT60TR13C radar wing board (SP005568071)  through UDP. For each chirp in the radar setting, I have 128 ADC samples.  But I found that there was always a noise at a fixed frequency as shown in the attached figure.  I tried to change the sampling frequency but this noise was still there. Do you know what caused this issue?

Thank you!

HI

I would like to build a trigger control for a youtube maker project , using the TLE493D-W2B6

I have an TLE493DW2B6 shield2go board, and I connected it to the Arduino 

I installed the library TLE493D

I copied the DrillTrigger_SpeedAsNumber example

https://github.com/Infineon/TLE493D-3DMagnetic-Sensor/tree/master/examples/DrillTrigger_SpeedAsNumber

connected the sensor to the ARduino UNO R3   I2C pins (checked with the oscilloscope I can see SCL adn SDA moving correctly)

Connected the VDD pin of the board to 3V3 and the GND to GND

but all I can read are always the same number (see screenhsot below)

even if I put a magnet on the top of the sensor:

am I missing something?

thanks

I tried to configure it using the above code, but it reports an error at device.set_acquisition_sequence(sequence).

Using the sample program found in the official distance_fft.py, using the

Perform the configuration. Is there any way to use config to configure it, or convert config to metrics and then configure it?

Hi, I am new to radar sensors.

To analyze radar data, I have plotted FIFO data read from BGT60TR13C in time domain.

My concern is whether the data in the form below is read correctly.

Could you please tell me what the raw data in the time domain usually looks like and if it is correct?

I set up a new project to test the MCU 4700. And I try to use P2.8 output a high level, because according to your user manual that P2.8 is not connected to any signal.

 Here is my testing firmware:

However, it still does not work, I can't test a high level in P2.8.

Could you please tell me what' going on here?

In the BGT60LTR11AIP shield XENSIV™ 60 GHz radar system platform application note, under SPI mode and motion detection algorithm, it states that a detection range of 14m is possible and that the firmware used to achieve this is the “Radar Advanced Motion Sensing with SPI” application available from the Radar Fusion GUI is used. However, I have tried downloading the radar fusion GUI and it is not clear how this algorithm works. I am trying to integrate the BGT60LTR11AIP into a product that will be mounted at 8m and currently i am only getting detection at around 4m so would like to see how this advanced motion detection range is possible. 

My radar is Distance2GoL. When I change the FMCW_PULSE_REPEAT_TIME from 5ms to 2.5ms

  I use an oscilloscope to check the TX_EN, however, it's look like this:

I think it's wrong.  If one frame lasts 100ms, and there should be 10 chirps in one frame and every chirp lasts 25ms. However, the TX_EN shows that this is only one chirp in a frame and the chirp lasts 25ms??? It's contradictory with the firmware.
Could you please tell me why?

And I here is my requirement, colud you please provide some suggestions for firmware modification?  Because ADC only only works in the up chirp time(1.5ms) according to your doc. And in pluse repetition time(5ms_default), only 1.5ms/5ms=30% duty cycle when the radar is acquaring raw data. I want to realize the radar acquires raw data as the most as possible. So I think if I change the pluse repetition time(5ms_default) to 2.5ms, the duty cycle becomes 1.5/2.5=60%.  So I met the problem I describe above. 

And I think just modify pluse repetition time is not enough, Because frame rate is 10Hz, and every 100 ms there is a frame. In the frame, just the first 2.5ms*10 chirps=25ms the radar will acquire the raw data(in fact only every 1.5ms*10 chirps in this 25ms ADC works).  So Can you provide some suggestions?

Hi friends,

TLE5012B E5000 is showing "System error" in "Safety Word" after reading the angle value every time.

However, Status Register (that is at 00H) doesn't show any of the errors corresponding to "S_VR; S_DSPU; S_OV; S_XYOL; S_MAGOL; S_FUSE; S_ROM; S_ADCT"

Refer: Infineon-TLE5012B_Exxxx-DataSheet-v02_01-EN.pdf  page 29

Thank you for providing insight on why this "System error" is observed in "Safety Word", how to overcome it.
