Microstepper motor device and method of controlling the device
A microstepper motor device and method of controlling the device uses a microcontroller that provides current sinusoidal values from at least one array of sinusoidal values to power circuitry of the device in response to control signals. The power circuitry is connected to a stepper motor of the device to supply power signals to the stepper motor using the current sinusoidal values. The microcontroller is configured to index the at least one array of sinusoidal values to the current sinusoidal values in response to the control signals as part of an interrupt service routine of the microcontroller. The microcontroller is further configured to transmit the current sinusoidal values to the power circuitry as part of a non-interrupt routine of the microcontroller.
