An analog device control system is disclosed. The analog device control system has an analog device control module, comprising computer-executable code stored in non-volatile memory, a processor, and an analog device. The analog device control module, the processor, and the analog device are configured to use the analog device to receive an analog signal, digitally control the analog device using the analog device control module, and vary the analog signal using the analog device. Varying the analog signal is based on digitally controlling the analog device using the analog device control module.
