Abstract
System and method for operating a motor using a single general purpose input/output (GPIO) pin of a controller. In one embodiment, a control circuit may include a first terminal coupled to a GPIO pin of a controller. The first terminal can be configured to receive, and output, at least one or more signals. The control circuit may include a plurality of elements coupled to the first terminal, and motor driver circuit output terminal, such that the control circuit may be configured to output one more control signals to the motor driver circuit output terminal for control the motor driver circuit. Motor driver control signals may be based, at least in part, on one or more signals received from the first terminal.
