Function Documentation

__usdelay()

void __usdelay

(

uint32_t

loop

)

get_arch_counter()

static uint64_t get_arch_counter ( void  )

inlinestatic

mdelay()

void mdelay

(

uint32_t

ms

)

Delay execution for a specified number of milliseconds.

This function converts milliseconds to microseconds and calls the udelay function to implement the delay.

Parameters

ms	Number of milliseconds to delay.

raise()

int raise

(

int

signum

)

time_ms()

uint32_t time_ms

(

void

)

Get the current time in milliseconds.

This function calculates the current time based on the architecture counter and returns it in milliseconds.

Returns

Current time in milliseconds.

This function calculates the current time by dividing the architecture counter value by the current HOSC frequency (in MHz) scaled to milliseconds.

Returns

Current time in milliseconds.

time_us()

uint64_t time_us

(

void

)

Get the current time in microseconds.

This function calculates the current time based on the architecture counter and returns it in microseconds.

Returns

Current time in microseconds.

This function calculates the current time by dividing the architecture counter value by the current HOSC frequency (in MHz).

Returns

Current time in microseconds.

udelay()

static void udelay ( uint32_t  us )
