+# Interrupts handling
+
+## Homework
+
+**(based on MPU6050 driver)**
+
+1. Setup handling of MPU6050 interrupts.
+- Configure interrupt request on MPU6050 (e.g. motion detection).
+- Connect interrupt output of the MPU6050 with Orange-Pi GPIO.
+- Configure GPIO as input.
+- Register handler for the MPU6050 interrupt.
+
+2. Implement deferred interrupt handler (e.g. in custom workqueue) to handle the request.
+- Read new measurements.
+- Implement measurements processing (e.g. the following or per your preference).
+  - filtering (e.g. moving average);
+  - integrating (for acc to get speed);
+  - determine trends;
+  - etc.
+
+3. Provide additional interface (e.g. in procfs) to read the processed data at once.
+
+_Note: Remember to synchronize all concurrent operations_
