+## Homework
+
+**(based on MPU6050 driver)**
+
+_NB_:
+Communication with peripheral device on i2c is quite slow asynchronous process
+which responsiveness depends on the slave latency and bus utilisation.  
+Thus generally it's better to be done in background process.
+
+1. Move interaction with MPU6050 into separate thread.
+
+2. Protect static data of the driver (`g_mpu6050_data` in the master)
+for the case of concurrent access.
+
+3. Limit interaction with MPU6050 in case of frequent requests:  
+Define validity interval - if the latest read data is older than this threshold
+then new data reading is performed, otherwise previously read data is returned.  
+(This threshold should be configurable parameter with reasonable default.)
