/*
|
|
The _delay_us function uses loops to generate an approximate delay for the specified number of microseconds.
|
|
It calculates the number of clock cycles required to achieve the requested delay and loops the corresponding number of times.
|
|
|
|
The temporal precision of _delay_us depends on the microcontroller's clock frequency (F_CPU).
|
|
For the ATmega328 operating at a typical frequency of 16 MHz, here are some details on the precision.
|
|
|
|
Clock Frequency: F_CPU must be defined correctly before using the function. For an ATmega328 operating at 16 MHz:
|
|
1 clock cycle = 1 / 16,000,000 s ≈ 62.5 ns
|
|
1 µs ≈ 16 clock cycles
|
|
|
|
HOLD _delay_us(2.75) = 44 clock cycles
|
|
PATCHING _delay_us(0.2) = 3,2 clock cycles
