Welcome to the Infineon Developer Community

my sensor is work well  with windows,

but when i plan  connect the sensor with ubuntu(20.04),

and try to run range-angle-map.py,

there has an error like below:

Traceback (most recent call last):
File "range-angle-map.py", line 122, in <module>
with Device() as device:
File "/home/zhangjj/work/2022/mmwave/RDK-TOOLS-SW/SDK/apps/py/examples/ifxRadarSDK.py", line 460, in __init__

and if i run command "lsusb" in linux,

is there has any idea for it?

Hello,

I develop my own algorithm.And I have a question about raw data.

Getting the raw data seems to be using frame_info->sample_data

Is to use uint16_t radar_get_frame(Radar_Handle_t device, Frame_Info_t* frame_info, uint8_t wait_for_data) in radar_base.c?

And how can I achieve complex style like matlab paradigm. (ex: 0.5008547 + 0.5177045*i)

Is sample_data = sample_data(1:frame_info.num_samples_per_chirp,:,:) + 1i * sample_data((frame_info.num_samples_per_chirp+1):end,:,:); complete the complex style in matlab?

Because my algorithm is based on matlab,so I need the raw data in complex style

Please reply back with how to get complex raw data like matlab in DAVE IDE.

Thanks

Can chip signals be changed in a project?

I want to change another chip signal, but I don't want to change the program under the current project unless it is necessary.

Hello,

This question is related to the HX3 design discussed in this review.

The HX3 hub was manufactures as in the above mentioned design and it looks like it works ok, we use it to connect a USB camera module (AR0144) to the PC/Laptop. The camera module is USB 3 and has a micro-B USB connector, we use a micro-B USB to type-C cable to connect the camera module to the HX3 hub.
we have 2 types of micro-B to type C cable (see attached cable A and cable B), everything works good with cable A but when connecting the camera module to the HX3 hub using cable B we get a "USB device not recognized". we connected the camera module directly to the PC with cable B and it works good, we also tested the camera module with cable B connected to a commercial USB-3 hub and it also works good. 

any ideas what can male cable B not work with the HX3?

thanks, 

MCE Designer becomes unresponsive and no longer able to turn off the Motor every time I tired to run PFC first and then run Motor.
But there is no problem if I turn on only one(either pfc or Motor) and run.

The  tools that I use for this application are: EVAL-M3-302F for controller and  EVAL-M3-CM615PN for power board. I have the latest version of MCE designer installed which is v2.3.1 and the MCE wizard that I have is v2.3.1. The firmware package that I use for board is IMC302A-F064 MCE Software Package v1.3.3 

Hi,

I am connecting up the iMotion-Link for the first time. I understand from my previous post (see link below) that I can use 5V logic on the target board.

https://community.infineon.com/t5/iMOTION-controller-driver-IPM/iMotion-Link-useable-for-interfacing-with-custom-board-with-IMC101TF-and-5V/m-p/346143/thread-id/436

However, now that I am using the iMotion-Link, I am not getting ANY signal out the RXD1 pin (which should transmit to the IMC101's RX0 pin on my board).  Both RXD1 and TXD1 pins from the iMotion-Link 8-pin header connector appear to be floating. Of course, the 3.3V switch is turned off as well.

I hook up the USB cable between PC and the iMotion-Link, run MCEDesigner, the virutal serial port appears (as COM10) and then I try to connect over the port. However, no signals are generated from the RXD1 and TXD1 pins.  What could be going wrong?

Do I need to apply my 5V power to the 3.3V pins on the header connector?  I thought that RXD1 pin would be driven without needing this.

I also verified that resistor R1 is not present on the iMotion-Link per previous posts on this issue. I purchased the unit earlier this year.

Thanks,

Hi, 

I patched the linux-5.4.40-cy-spimem.patch to TI provided SDK.

And I modified the device tree like below,

&main_spi0 {
pinctrl-names = "default";
pinctrl-0 = <&main_spi0_pins_default>;
ti,pindir-d0-out-d1-in = <1>;
nvram@0 {
compatible = "cy-spimem", "jedec,spi-nor";
reg = <0>;
spi-max-frequency = <40000000>;
#spi-cs-high;
#data-size = <16>;
};
};

But the spi speed is not 40Mhz as expected. Please help to point out how to set the spi speed in device tree for FRAM?

Best Regards
