My code is supposed to simulate a system where multiple sensors collect data concurrently and process them. But I get this

Segmentation fault (core dumped)

Segmentation fault (core dumped)

error thrown in my console as the code crashes. Please what am I doing wrong ?

Hello! I would like some advice on choosing a servo motor. It would be used to create rotating metal airsoft targets (a 20cm circle weighing a few hundred grams). The goal is for the targets to rotate 90 degrees very quickly.
Which model do you recommend??

Hello, if there isn't much weight, a Nema17 will be perfect, you can even create random sequences of movement on predefined angles.

Humm ok thanks @aymen ammari @nour_huda I’ll look into the NEMA 17 servo motor and see how it stacks up for my rotating targets.

I'm a huge fan of high-quality open-source solutions. It was a pleasure meeting with Frédéric Desbiens, the Program Manager @ Eclipse Foundation.

Frederic was a guest on my "Internet of Things equation" podcast. I'm excited about the new opportunities to collaborate with Eclipse and cover their solutions in my future content.

Which Eclipse Project is most interesting/relevant to you? Please put your pick in the comments!

Joseph Ogbonna•4/10/24, 12:01 PM

Seems like your

pthread_create()

pthread_create()

does not receive the correct argument, which should be the address of the

SensorData

SensorData

struct, not the address of the

value

value

field within the struct.

This part of your code :

rc = pthread_create(&sensor_threads[t], NULL, sensor_task, (void *)&sensor_data[t].value);

rc = pthread_create(&sensor_threads[t], NULL, sensor_task, (void *)&sensor_data[t].value);

Change it to pass the address of the

SensorData

SensorData

struct instead:

rc = pthread_create(&sensor_threads[t], NULL, sensor_task, (void *)&sensor_data[t]);

rc = pthread_create(&sensor_threads[t], NULL, sensor_task, (void *)&sensor_data[t]);

Marvee Amasi•4/10/24, 8:45 PM

You should look for guides on brushless motor selection based on factors like KV rating (speed) and motor size (torque).
Also Research propeller selection based on diameter, pitch (thrust vs. speed), and number of blades.

Also check based on your application if you will need a shielded or an unshielded Inductor, when planning your design.
