Task 1-A: Design Half Step Sequence Driver Design a half-step sequence stepper motor driver digital circuit. Half-step sequence mode states (combination) causes step angle of shaft rotation in stepper motor (step angle 0 = 0.9"). The three modes of operation are shown in Table 1. There are only four states in the full-step sequence and wave-drive sequence. On the other hand, there are eight states in the half-step sequence as shown in table 1. Figure 1 shows the stepper motor driver where it has two inputs and four outputs. If D=1 the sequence will be the sequence in the table from row 1 to row 8 and If D=0 the sequence will be from row 8 to row 1. The second input is the clock input which controls the speed of operation.
