48:C:/WinAVR/avr/include/util/delay.h **** Obviously, in that case, no \c \#define statement should be
49:C:/WinAVR/avr/include/util/delay.h **** used.
50:C:/WinAVR/avr/include/util/delay.h ****
51:C:/WinAVR/avr/include/util/delay.h **** The functions in this header file implement simple delay loops
52:C:/WinAVR/avr/include/util/delay.h **** that perform a busy-waiting. They are typically used to
53:C:/WinAVR/avr/include/util/delay.h **** facilitate short delays in the program execution. They are
54:C:/WinAVR/avr/include/util/delay.h **** implemented as count-down loops with a well-known CPU cycle
55:C:/WinAVR/avr/include/util/delay.h **** count per loop iteration. As such, no other processing can
56:C:/WinAVR/avr/include/util/delay.h **** occur simultaneously. It should be kept in mind that the
57:C:/WinAVR/avr/include/util/delay.h **** functions described here do not disable interrupts.
58:C:/WinAVR/avr/include/util/delay.h ****
59:C:/WinAVR/avr/include/util/delay.h **** In general, for long delays, the use of hardware timers is
60:C:/WinAVR/avr/include/util/delay.h **** much preferrable, as they free the CPU, and allow for
61:C:/WinAVR/avr/include/util/delay.h **** concurrent processing of other events while the timer is
62:C:/WinAVR/avr/include/util/delay.h **** running. However, in particular for very short delays, the
63:C:/WinAVR/avr/include/util/delay.h **** overhead of setting up a hardware timer is too much compared
64:C:/WinAVR/avr/include/util/delay.h **** to the overall delay time.
65:C:/WinAVR/avr/include/util/delay.h ****
66:C:/WinAVR/avr/include/util/delay.h **** Two inline functions are provided for the actual delay algorithms.
67:C:/WinAVR/avr/include/util/delay.h ****
68:C:/WinAVR/avr/include/util/delay.h **** Two wrapper functions allow the specification of microsecond, and
69:C:/WinAVR/avr/include/util/delay.h **** millisecond delays directly, using the application-supplied macro
70:C:/WinAVR/avr/include/util/delay.h **** F_CPU as the CPU clock frequency (in Hertz). These functions
71:C:/WinAVR/avr/include/util/delay.h **** operate on double typed arguments, however when optimization is
72:C:/WinAVR/avr/include/util/delay.h **** turned on, the entire floating-point calculation will be done at
73:C:/WinAVR/avr/include/util/delay.h **** compile-time.
74:C:/WinAVR/avr/include/util/delay.h ****
75:C:/WinAVR/avr/include/util/delay.h **** \note When using _delay_us() and _delay_ms(), the expressions
76:C:/WinAVR/avr/include/util/delay.h **** passed as arguments to these functions shall be compile-time
77:C:/WinAVR/avr/include/util/delay.h **** constants, otherwise the floating-point calculations to setup the
78:C:/WinAVR/avr/include/util/delay.h **** loops will be done at run-time, thereby drastically increasing
79:C:/WinAVR/avr/include/util/delay.h **** both the resulting code size, as well as the time required to
80:C:/WinAVR/avr/include/util/delay.h **** setup the loops.
