need alternate solution for AVR delay library

[vishu489]

Hello friends

I'm trying to optimize my code size which is return for atmega8. After spending several hours i found that the actual reason behind my code bulkiness is utilization of avr inbuilt delay.h library which has all the inline function. Can anyone suggest me different way of getting delay which will reduce code memory usage as compare to _delay_ms() and _delay_us() function. Also i dont want to use timer since not having any one of them free and i dont need accurate delay.

Also when i tried to convert _delay_ms() and delay_us() function from inline to general compiler gives me error of memory overflow
and When i tried following method my code size was bigger than previous one

Void Delay_ms(uint16_t Duration)
{
while(Duration != 0)
{
_delay_ms(1U);
--Duration
}
}

if _delay_ms() function is inline then compiler should replace it by function body only within Delay_ms() and not anywhere else
Then why my code size is increasing? i want to decrease my flash usage since it almost 78% full

please help me

Thank you in advance

The question will be usually answered by looking into the assembly listing and linker map.
