With a pulse applied to the winding input, the rotor rotates by one teeth position or an angle x.

Only lower data bus D 0 — D 7 is used as is 8-bit device. Port A acts as a 8-bit input data port to receive the digital data output from the ADC. Ports A, B, and C can be individually programmed as input or output ports Port C is divided into two 4-bit ports which are independent from each other Mode 1: About project SlidePlayer Terms of Service. The count for rotating the shaft of the stepper motor through a specified angle may be calculated from the no.
