Alexander Rakhman / Mbed 2 deprecated MaxSonarTTL2Flash

Looking up interrupts from MaxBotix Maxsonar MB73x0 ultrasonic gauge and writing data and timestamp to SD flash card. I'm using MB7380 with STM32F103C8T6 minimal board from Ali (it's perfect MCU board for small projects!).

Dependencies:   SDFileSystem mbed
