PID Tuning | How to Tune a PID Controller - RealPars

Let’s discuss what the PID parameters are and how they are used.

Thank you, i appreciate it

@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.

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.

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 Location

Vector 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

MMarvee Amasi I don't know if the compiler and linker settings are configured correctly to pla...

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

Hello

DP65FL•11/5/24, 10:17 PM

Hi everyone!

Just joined the community and thought I’d introduce myself. I’ve always been into electronics – started out building little circuits, got my HAM license, and even built my first computer, a ZX Spectrum, back in high school.

I’m a Maritime SATCOM professional with over 25 years of experience in tech support, product training, integration/testing, project management, SATCOM/RF solutions, and consulting.

Recently, I've been diving into the IoT space, and it’s been an exciting new journey!

I’m based in Florida and would love to connect with others who are also into IoT.

Looking forward to learning, sharing ideas, and meeting like-minded folks here.

Thanks for the warm welcome!

Ssegfaultdev.elf but according to my compiled program

Try increasing your stack size.
How many tasks/thread do you intend to create?
