  37 +
  38 +The project uses the operating system [FreeRTOS](https://www.freertos.org/). It contains 4 tasks as showing the table below:
  39 +
  40 +|Task|Priority|Role|
  41 +|:--:|:------:|:--:|
  42 +|Task1|1|Collecting the OBD data with 1 sample/90ms|
  43 +|Task2|1|Collecting GPS data(longitude, latitude, altitude, GPS speed) and IMU data (accelerometer, gyroscope and magnetometer along the 3 axes (X, Y, Z))|
  44 +|Task3|1|Collecting the OBD data with 1 sample/60s|
  45 +|Daemon Task|3|Writing data in SD card|
  46 +
  47 +Below is a table representing the various OBD data required, as well as how often they are taken:
