Abstract
A method and apparatus are disclosed for generating multiple separate analog signals using a single microcontroller output pin. The microcontroller generates a waveform that is used to concurrently generate multiple separate analog signals. The microcontroller outputs a waveform that includes a first signal from one of the microcontroller's output pins. The first signal is used to produce a first analog signal. The microcontroller then outputs a delineating signal, as part of the waveform, from the microcontroller's output pin. The delineating signal indicates the start of a next signal in the waveform. The microcontroller then outputs a second signal, as part of the waveform, from its output pin. The second signal is used to produce a second analog signal. The waveform includes the first signal that is followed by the delineating signal that is followed by the second signal.
