How to read data from arduino and analyze in real time

Hi, I trying to make a program that get data from arduino and i wrote a code that analyze the data. My problem is that the analyze are take longer time in ratio to the read the data. I want to find some method that maybe can run the read data function from the arduino in the background and analyze the data in real time (running them in parallel). Even if there is some delays its ok. Any suggestions?

1.Create two separate threads—one for data reading and one for data analysis. Each thread will execute its respective function independently.

1. Data Reading Thread: In this thread, continuously read data from the Arduino using the appropriate communication protocol (e.g., serial communication). You can use functions like Serial.read() to retrieve data from the Arduino. Make sure to implement any necessary synchronization mechanisms (e.g., locks or semaphores) to avoid conflicts when accessing shared resources.
2. Data Analysis Thread: In this thread, perform the data analysis on the received data. Write the code to analyze the data according to your requirements. This thread will run concurrently with the data reading thread.

2.Implement a mechanism for communication and synchronization between the two threads. This can be achieved using shared data structures or message passing techniques. For example, you can use a shared buffer to store the data read from the Arduino, and the analysis thread can process the data from this buffer.

3.Depending on the real-time requirements of your application, you may need to consider factors such as thread priorities, synchronization delays, and buffer sizes to ensure timely and accurate data analysis.

It's important to note that multi-threading can introduce complexities, such as potential race conditions or synchronization issues.

Hope this helps!
