what sort of malfunction are you seeing?

Cespost•11/3/24, 4:42 PM

Hey new here :)

ZZacckOsiemo whats the next half

futurespacer•11/3/24, 4:44 PM

the current system is one system doing upto 5 automations; the next stage is to modularize the automations in individual, pcb designed embedded system and specialize on automation that don't already have other existing solutions e.g ( as per your example using an AC intead of doing away with the fan regulator- the reason i went straight to automating the fan is because more people already own this and it would be easier and simpler to replace )

ZacckOsiemoOP•11/3/24, 4:46 PM

Ah are you trying to make a business out of this? Well you can still maintain a proof of concept using the fan then later when in applicable market you can use AC

Renuel Roberts•11/3/24, 4:49 PM

like the model no longer respond acuately when initialized and gives an unexpected responce, for instance if the model was used to automate predictive maintenance for small motors it tend to return random feedbacks not according to its trained data and they are most inacurate but if the full model is ran with out pruning its 90% accurate most of the times

ZacckOsiemoOP•11/3/24, 4:50 PM

could it be a problem with your training or is it overflowing memory and returning garbage what are you doing to cause this?

futurespacer•11/3/24, 4:52 PM

just borrowing concepts from industrial automations to home automations without making things too complicated hence the need for PID control since specializing in one automation at a time means i can do more than just a closed loop system

ZacckOsiemoOP•11/3/24, 4:53 PM

Ah thats a good way to look at it, well in that case do the fan control then later you can move to a full controller

futurespacer•11/3/24, 4:56 PM

alright thank you, the other automations are light control, humidity control, ventilation control, curtain control, and access control(all in one embedded system)

@ZacckOsiemo @techielew i have project based in board stm32f4 dicovery and i should be management modules (dht22,lcd_i2c,rfid rc522,etc) in real time using FreeRTOS ... i use in this project stm32cubemx and iar embedded workbench

ZacckOsiemoOP•11/3/24, 7:25 PM

Nice! tell us more about this project, please.

Ala Hassine•11/3/24, 7:42 PM

ok no problem ... The goal of this project is to develop a home automation system for controlling and monitoring various household elements. The system will manage common household devices and detect essential parameters, such as humidity, temperature, and RFID tag presence, allowing for actions like controlling lights or opening and closing doors with a motor. Additionally, the system will be managed in real-time using FreeRTOS to ensure efficient and timely response to user commands and environmental changes.

techielew•11/3/24, 9:45 PM

You asked about FreeRTOS bringup on this before. What issues have you been experiencing in this setup?

techielew•11/3/24, 9:45 PM

(if any)

rahulroy_7•11/4/24, 8:05 AM

@Ala Hassine for the monitoring data you can use UART based display module also?

what part of that combination is problematic for you?

Hi @Ala Hassine Here's dedicated Engineering Hour session about using FreeRTOS with STM32CubeIDE timestamp 35:19. Its detailed and step-by-step guide https://www.youtube.com/watch?v=reX6S8x94eM. I'm sure this video will answer otherwise we'll be happy to help you.

ZZacckOsiemo what part of that combination is problematic for you?

my problem is how i can configurate freertos in stm32cubemx and how for example generate many tasks in same time

Marvee Amasi•11/4/24, 7:53 PM

Right there in the stm32cubemx go to the middleware section and turn on freeRTOS . After dat you should check wher you would see Tasks and Queues and click Add to make more of tasks. When the code is generated, you’ll see the tasks in freertos.c

Marvee Amasi•11/4/24, 7:54 PM

You can then edit the StartDefaultTask()StartDefaultTask() function to set what each task does

ZacckOsiemoOP•11/5/24, 1:15 AM

What configuration settings are you trying to set up and why do you need to genetate multiple tasks?

segfaultdev.elf•11/5/24, 5:24 PM

i am getting error after calling vTaskStartScheduler(); vTaskStartScheduler();

segfaultdev.elf•11/5/24, 5:24 PM

Can anyone help

segfaultdev.elf•11/5/24, 5:24 PM

I googled a bit they says it is an issue with the Vector Table LocationVector Table Location

segfaultdev.elf•11/5/24, 5:25 PM

but according to my compiled program

segfaultdev.elf•11/5/24, 5:25 PM

it is already on the right location

Ssegfaultdev.elf I googled a bit they says it is an issue with the `Vector Table Location`

Marvee Amasi•11/5/24, 5:38 PM

I don't know if the compiler and linker settings are configured correctly to place the .isr_vector section at the appropriate address

segfaultdev.elf•11/5/24, 5:41 PM

yes it is

segfaultdev.elf•11/5/24, 5:42 PM

i keep isr always at the top

segfaultdev.elf•11/5/24, 5:42 PM

also if it was wrong how I can reach main

segfaultdev.elf•11/5/24, 5:42 PM

reset handler also resides inside the vector table

Marvee Amasi•11/5/24, 5:45 PM

Well I haven't encountered something like this , what's actually the error

Ssegfaultdev.elf i am getting error after calling ` vTaskStartScheduler();`

segfaultdev.elf•11/5/24, 5:46 PM

after this function called mcu goes into hardfault

Marvee Amasi•11/5/24, 5:52 PM

From what I know freeRTOS uses multiple stacks, one for each tasks , and an incorrectly sized stack for the tasks can lead to a hardfault

Marvee Amasi•11/5/24, 5:53 PM

If the task stack size is too small, maybe increase it

MMarvee Amasi If the task stack size is too small, maybe increase it

segfaultdev.elf•11/5/24, 5:58 PM

noted. I will try tomorrow

techielew•11/5/24, 7:11 PM
