Function Name: Utility_delay
|
|
|
55 |
Function Description: This function provides a busy-wait
|
|
|
56 |
delay for a specified number of milliseconds.
|
|
|
57 |
Inputs: numMs - the number of milliseconds to delay
|
|
|
58 |
Outputs: none
|
|
|
59 |
NOTES: The delay_loop_1 and delay_loop_2 functions found
|
|
|
60 |
in avr/delay.h provide accurate 3 and 4 cycle delay loops
|
|
|
61 |
if needed...this isn't really a millisecond, so DON'T
|
|
|
62 |
depend on it for exact timing...
