    摘要: Two standard waves from a standard waveform generation circuit are output via an output gate while being interchanged by a direction selector. The switching operation of the direction selector is controlled by a direction control signal M/I. 200 cycles of the standard waveforms are counted by a 200-cycle counter. A drive counter is downcounted every 200 cycles, while the drive counter is upcounted in accordance with the number of drive pulses DRIVE. When the count value of the drive counter becomes zero, output from the output gate is thereby stopped.

    摘要: Two standard waves from a standard waveform generation circuit are output via an output gate while being interchanged by a direction selector. The switching operation of the direction selector is controlled by a direction control signal M/I. 200 cycles of the standard waveforms are counted up by a 200-cycle counter. A drive counter is downcounted every 200 cycles, while the drive counter is upcounted in accordance with the number of drive pulses DRIVE. When the count value of the drive counter becomes zero, output from the output gate is thereby stopped. At the time of startup, outputs from the 200-cycle counter are counted so as to output a drive wave in a predetermined number in a predetermined direction.

    摘要: To generate a drive wave for driving a piezo-actuator. Drive data concerning the number of drive waves supplied through a serial bus is stored in a drive data storage unit. A comparing circuit detects whether or not the number of drive waves have been generated, the number being specified by the drive data, and the drive wave keeps being generated until such detection is made.

    摘要: Fundamental waveform data transferred through a serial interface is stored in a register. A fundamental waveform generation circuit uses the data to generate a fundamental waveform. A selector is capable of providing fundamental waveform data stored in a fixed memory to the register to replace the fundamental waveform data provided through the serial interface. An initial counter provides a low level signal to an exclusive OR gate until its count value reaches a first predetermined value. A direction control signal M/I is provided to the exclusive OR gate from an external source and the direction control signal M/I at high or low level inverts a direction control signal to be provided to a direction selector.
