I am trying to find a way to add four 4-bit binary numbers to a 16-bit shift register, one(group of 4 bits) by one. This way I can store 4 decimal numbers(0-9) in the register, adding them by pushing ...
The trivial case is to use SRL to express multiplication: val * 2^num => val sll num val sll 2 + val sll 8 => val * 10 Do ...
I was looking at the SN74HC164N shift register datasheet and I noticed something that intrigued me: There are 2 input signals A and B, but they are NAND'd together to produce the final output. My ...
I must be blind... I'm trying to decide which of the '165, '166, and '597 shift registers is appropriate/inappropriate for a SPI input shift register. All are 8-bit parallel in. HC165: ...
