HOW TO EXPORT THE KEIL PROGRAM FROM MBED
Circuit debugging are unavailable in mbed. However, mbed has “Import Program” and “Export
Program” functions. You can export the programs in mbed as Keil programs to perform
debugging.
The mbed library file can also be exported, which includes the HAL library of STM32 MCU. Under
the Keli environment, mbed libraries can be applied or modified directly, and can be
transplanted into other applications.
