Hi Aymen !

It depends on your specific needs and budget

aymen ammari•3/23/24, 1:25 AM

I need at least 6 channels, and the budget

50$ maximum?

Camila_99$$•3/23/24, 1:32 AM

Camila_99$$•3/23/24, 1:33 AM

So I suggest you Flysky FS-i6X: An upgraded version of the FS-i6, the FS-i6X offers additional features like telemetry support and a more modern interface. And it’s around 54$

Hey guys, please I need your help here . I'm working on a home automation system using FreeRTOS and experimenting with Round-Robin scheduling for fair task execution. I'm facing issues with critical tasks like sensor data processing and actuator control getting delayed, affecting system responsiveness. I've tried adjusting priorities and time quantum, but the performance isn't as expected. Any tips for optimizing Round-Robin scheduling in FreeRTOS for real-time applications, or suggestions for alternative algorithms that might work better?

Joseph Ogbonna•3/23/24, 8:19 AM

Consider using a different scheduling algorithm like Earliest Deadline First (EDF) or Rate Monotonic (RM) for better real-time performance in your home automation system. These algorithms are often more suitable for meeting timing requirements compared to Round-Robin scheduling in FreeRTOS.

Marvee Amasi•3/23/24, 9:04 AM

Hmm, EDF

thanks @Joseph Ogbonna

Sstreetdogg are these periodic tasks?

Marvee Amasi•3/23/24, 9:05 AM

Yes, some of the tasks are periodic, such as sensor data sampling and actuator control updates. However, I'm also dealing with non-periodic tasks like user interface responsiveness and event handling.

streetdogg•3/23/24, 9:26 AM

cool. I think you should assume all the tasks to be periodic and come up the CPU utilisation factor. If that is within 70%, the tasks can be scheduled and no deadline will be missed. If u see that the utilisation is more than 70%, then u need a CPU thats faster or u need to optimise the code to be faster.

Hi everyone

Camila_99$$•3/23/24, 2:01 PM

I used a laser distance sensor (CJMCU-530 Laser) with an Arduino, which is supposed to have a maximum distance of 2m, but in my various tests, I have never managed to exceed 1.2m... Has anyone else experimented with this distance sensor? Otherwise, do you have a reference for another sensor (I need a distance between 0 and 2m) besides the ultrasonic sensor SRF05.
Thank you.

CCamila_99$$Welcome @Prem Thengil

Prem Thengil•3/23/24, 2:03 PM

You Can Try Ultrasonic Sensor (HC-SR04) its Range Is From 2/3cm to 400cm

"What Is Green Software Engineering?
The path to green software began more than 10 years ago. The Sustainable Web Design Community Group of the World Wide Web Consortium (W3C) was established in 2013, while the Green Web Foundation began in 2006 as a way to understand the kinds of energy that power the Internet. Now, the Green Web Foundation is working toward the ambitious goal of a fossil-free Internet by 2030."

Doesn't this imply basically fossil free world by 2030? All of the infrastructure powering the Internet would have to be powered by green energy lol
