void delay_ms

(

unsigned int

t

)

Delay for the specified number of milliseconds.

Implemented using busy-waiting, so time spent in ISRs does not count. This is also only an approximate delay.

Note: must be compiled with F_CPU set for the target system clock configuration. We assume that F_CPU is divisible by 4000

Parameters:

t

Number of milliseconds to delay.

void delay_us

(

unsigned int

t

)

[inline]

Delay for the specified number of microseconds.

Implemented using busy-waiting, so time spent in ISRs does not count. This is also only an approximate delay.

Note: must be compiled with F_CPU set for the target system clock configuration. We assume that F_CPU is divisible by 1,000,000

Parameters:

t

Number of microseconds to delay. For 1MHz clock: delay up to 65535 us, with a resolution of 4 us For 16MHz clock: delay up to 4095 us, with a resolution of 1 us
