Honza T. / Mbed 2 deprecated EXAMPLE_Nucleo_mbed_RTOS_test_code

Simple test program to get familiar with functionality of MBED RTOS on ST Nucleo-F411RE. Tasks for LED blinking, user button, temperature measurement with DS1620, temperature measurement with internal temperature sensor of ST32F411RE, ultrasonic distance measurement and displaying result on 16x2 TextLCD.

Dependencies:   DS1620_improved TextLCD_improved mbed-rtos mbed
