Damian Gabino / picoGW_mcu

MCU driver/HAL for the Picocell Gateway concentrator board. The firmware implements either a USB CDC protocol or a UART protocol to bridge commands coming from host to the SX1308 SPI interface.

dgabino 0:c76361bd82e8 27 /* There are two memory tracers in mbed OS:
dgabino 0:c76361bd82e8 28
dgabino 0:c76361bd82e8 29 - the first can be used to detect the maximum heap usage at runtime. It is
dgabino 0:c76361bd82e8 30 activated by defining the MBED_HEAP_STATS_ENABLED macro.
dgabino 0:c76361bd82e8 31 - the second can be used to trace each memory call by automatically invoking
dgabino 0:c76361bd82e8 32 a callback on each memory operation (see hal/api/mbed_mem_trace.h). It is
dgabino 0:c76361bd82e8 33 activated by defining the MBED_MEM_TRACING_ENABLED macro.
dgabino 0:c76361bd82e8 34
dgabino 0:c76361bd82e8 35 Both tracers can be activated and deactivated in any combination. If both tracers
dgabino 0:c76361bd82e8 36 are active, the second one (MBED_MEM_TRACING_ENABLED) will trace the first one's
dgabino 0:c76361bd82e8 37 (MBED_HEAP_STATS_ENABLED) memory calls.*/
