Define Documentation

#define NUTMEM_END   (u_short)(NUTMEM_START + (u_short)NUTMEM_SIZE - 1U)

Last memory address without using external SRAM. Todo: Shall we support NUTRAMEND for backward compatibility? If, then let's do it in cfg/memory.h.

Function Documentation

void NutInit (  void   )

Nut/OS Initialization. Initializes the memory management and the thread system and starts an idle thread, which in turn initializes the timer management. Finally the application's main() function is called.

void NutThreadSetSleepMode (  u_char  mode  )

Sets the sleep mode to enter in Idle thread. If the idle thread is running, no other thread is active so we can safely put the mcu to sleep. Parameters: mode  one of the sleep modes defined in avr/sleep.h or sleep_mode_none (don't enter sleep mode)

void NutIdle (  void *  arg  )

AVR Idle thread. Running at priority 254 in an endless loop.
