In Zynq SoC the DMA is writing in memory with big-endian there is a way to change it to little endian, i found big trouble locating my header in a memory when is written in different memory case

Good day guys

, Please I really need to know what happens if there's no idle task in an RTOS? Does the system automatically generate one? And besides consuming CPU time, what other roles do idle tasks play?

How doing a byte swap for 32 bit(or whatever) data as you store it in the memory... you can implement this logic in FPGA side as well if that's where you are.

i have added this block before thr t_axis_data of the dma what do you think: module EndianSwap(
input [31:0] InputData,
output reg [31:0] OutputData
);

always @ (InputData)
begin
OutputData[31:24] = InputData[7:0];
OutputData[23:16] = InputData[15:8];
OutputData[15:8] = InputData[23:16];
OutputData[7:0] = InputData[31:24];
end

AJAY KUMAR V•3/21/24, 1:52 AM

Sorry for the late reply @Phoenix
The internship was related to TI's TIVA and SimpleLink based low speed driver integration and product testing. I'm interested in IoT as well.
The startup is working on smart and handheld medical equipment development and gives service to redesign of system with new features as per requirement.
Thank you for asking

Hello Experienced Discord Users,

I am currently working on my graduation project which involves creating a human following robot. I would greatly appreciate your expertise and assistance in this project. Specifically, I am looking for guidance on how to download the Raspberry Pi operating system on a Windows computer and the recommended size of an SD card for this task.

Thank you in advance for your help and support.

Best regards,

Umesh Lokhande•3/21/24, 2:35 PM

Hi @406399 I'd suggest using 32 GB Micro SDCard. You can use Raspberry Pi Imager s/w which makes the entire process of writing OS image on SDcard easier than that of manually downloading RPi OS. https://www.raspberrypi.com/software/. I think for project you may need to interface Camera with RPi along with Computer Vision capabilities using OpenCV libs

Marvee Amasi•3/21/24, 2:38 PM

Exactly, to download the Raspberry Pi operating system on a Windows computer, you can use the official Raspberry Pi Imager tool. Here is the open source repo :
@https://github.com/raspberrypi/rpi-imager
. As for the SD card size, a minimum of 8GB is recommended, but for better performance and storage capacity, consider using a 16GB or 32GB SD card. I wish u good luck with your project @406399

welcome @406399 , actually i did try doing human following robot using multiple methodes , for indoor , i tried to use LIDAR.. it is a bit expensive but if ur univ provide u with it would be a great choice , also i tried using computer vision to identify the person .. the problem is the person have to always face the robot ( here am talking about recognizing a spesific person...) , also i tried using gps ... didn't give a really good result ... for any qst please feel free to ask

Good evening.
I've tinkered with a set of 4 switches/pedals to generate keyboard shortcuts on PC.
Everything works perfectly with a Chinese clone of Arduino Pro Micro.
Are there any other Arduino boards with USB ports that also support the Keyboard.h library?
I tried the Nano... Incompatible.
Thank you.

Marvee Amasi•3/21/24, 11:06 PM

For your project, you can consider Arduino Leonardo or Arduino Micro. Both boards have USB ports and support the Keyboard.h library, allowing you to generate keyboard shortcuts on your PC, very similar to the Arduino Pro Micro but offer compatibility with the Keyboard.h library

I would love to do this! Like a hard one as in i cant just use solder paste and a heat gun?

i am very new to freertos do you have any example code or project ?
