I'm just getting into shift registers and have his a knowledge wall where I can't seem to find how to interface a shift register without a latch pin to arduino.
All the arduino tutorials mention the use of the latch pin to change the outputs.
I have a BU2090 12 bit SIPO and I need to learn how to code it to work correctly.
I'm a bit perplexed how a chip without a latch pin will know where the 1st bit is in the 12 bit stream.
Am I thinking correctly?
Any help with knowledge or coding would be greatly appreciated. TIA
