Detailed Description

Macro Definition Documentation

◆ TICK_TO_US

#define TICK_TO_US ( tk )

Value:

(((tk)*88+52)/105)

◆ US_TO_TICK

#define US_TO_TICK ( us )

Value:

(((us)*105+44)/88)

Function Documentation

◆ bsp_idle_thread()

void * bsp_idle_thread ( uintptr_t ignored )

Optimized idle task.

This idle task sets the power mode to idle. This causes the processor clock to be stopped, while on-chip peripherals remain active. Any enabled interrupt from a peripheral or an external interrupt source will cause the processor to resume execution.

To enable the idle task use the following in the system configuration:

#include <bsp.h>
 
#define CONFIGURE_INIT
 
#define CONFIGURE_IDLE_TASK_BODY bsp_idle_thread
 
#include <confdefs.h>
