Jörg Wempe / Mbed OS Nucleo_L432KC_Test

Nucleo-L476RG using SD-CARD library. The program is functioning but might get problem if you update the mbed. In two different times I got problem with mbed library as no SPI clock was generated. At the time I publish this library the mbed is broken.

Dependencies:   BufferedSerial SDFileSystem
