Thanks for the warm welcome! I have been working with @techielew for a long time and am starting to help out in the community. I have a EE degree but have spent my whole career writing. I used to work for EE Times, for example. Nice to meet you!

hello , Can a timer, for example TIMER2, be used in multiple modes at the same time? In other words, can it count down 4 minutes and output a continuous PWM signal at the same time?

It depends on the specific microcontroller and its capabilities. In some microcontrollers, such as those with advanced timer features, it's possible to configure a timer to operate in multiple modes simultaneously. However, in many cases, timers are dedicated hardware units that can only operate in one mode at a time. You'll need to consult the datasheet or reference manual of the microcontroller you're using to determine if it supports concurrent operation of multiple timer modes.

just arduino

aymen ammari•4/8/24, 1:53 PM

This is called multi tasking, and the atmega can not provide this..... But it can if you code it properly to do tow functions simultaneously at high speed, it will appear like in the same time

aymen ammari•4/8/24, 1:53 PM

But a pmw signal..... I don't think that it can

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.

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 OgbonnaOP•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 SensorDataSensorData struct, not the address of the valuevalue 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 SensorDataSensorData 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.
