But i need to concurrent to display the data and reading the flow rate do i need to set task 1 for lvgl and task 2 for reading the sensor in a freertos environment

youcef_ali•3/20/24, 8:25 AM

Yes I suggest first ensure that you are reading the right value, ensure each task separately and combine everything together

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?

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

PPhoenix nice, is your internship related to iot ? what's the startup about

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
