-This part of library contains functions to generate delays in program with software algorithms or with hardware timers. Delays do not block interrupts therefore software delays are interfered by them. Delay functions are not pre-compiled to be compatible with different clock frequencies.+This part of library contains functions to generate delays in the program with software algorithms or with hardware timers.

-    Hardware timer based delay in milliseconds. Functions uses ATmega128 8-bit timer 0. Depending of the clock frequency, delay error up to several milliseconds may occur. Parameters:+    Hardware timer based delay in milliseconds. Functions use ATmega128 8-bit timer 0. Depending of the clock frequency, up to several milliseconds delay error  may occur. Parameters:
     * //count// - Delay time in milliseconds. 0 to 65535 ms.     * //count// - Delay time in milliseconds. 0 to 65535 ms.
