Hi to all friends here.
i want to try to experiment with shift register using the classic 74HC595 ic to add extra Digital output pins ( and later 74HC165 ic for input).
i have seen a lot of examples through internet but all have the same approach.. using "for" loop to make some leds to go on and off or make the famous kit (knight rider) led strip
As the "Shift Register" was and still is a pain in the @#$ for me to understand it clearly , i would like to see a example in real situation.. in order to make me understand it
what if we want to change the output state of the pin 3 only of the 74HC595 ?
should we know the state of all other pins in order to change the pin 3 or we can just send command to change only this pin without take in consideration of other pins state?
That is why i would like to see a sample code of a real project in order to understand the use of the shift register
thanks in advance
