for shift register on the rising edge of clock pulse the data present on the D pin will be transfered to Q0, then on the next pulse again data present on D will be transfered to Q0 while the previous Q0 value will be shifted to Q1 and so on...
so you need either a high or low level on D pin...
while in RS232 when you send a single character it is send like
Start bit --> 8 bit character data --> Stop bit
read about RS-232....
we already solved the problem..can you teach us the algorithms used in controlling the stepper in matlab?thank you
