FunctionGenerator

Arduino library to generate wave forms (nummeric) for a DAC

Description

TODO.

Interface

Constructor

• funcgen(float period = 1.0, float amplitude = 1.0, float phase = 0.0, float yShift = 0.0) All parameters can be set in the constructor but also later in configuration.

Configuration

• void setPeriod(float period = 1.0) // seconds
• float getPeriod
• void setFrequency(float freq = 1.0) // Hertz
• float getFrequency()
• void setAmplitude(float ampl = 1.0) // -
• float getAmplitude()
• void setPhase(float phase = 0.0) // phase of period
• float getPhase()
• void setYShift(float yShift = 0.0) // shift in amplitude, zero point.
• float getYShift()

Wave forms

t is time in seconds

• float sawtooth(float t)
• float triangle(float t)
• float square(float t)
• float sinus(float t)
• float stair(float t, uint16_t steps = 8)
• float random()
• float line()
• float zero()

Line() and zero() are functions that can be used to drive a constant voltage from a DAC and can be used to calibrate the generator / DAC combination.

Operational

See examples.

TODO

ideas for the future...

• example with DAC. 8 12 16 bit.
• example with potmeters for 4 parameters
• RC function
• Trapezium
• Sawtooth reverse?
• play "recording"
