FunctionGenerator

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

Description

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.
