Square wave

float uz_wavegen_square(float amplitude, float frequency_Hz, float duty_cycle)

Returns one sample of a square wave.

Parameters:

• amplitude – Amplitude for the square wave

• frequency_Hz – Frequency for the square wave in Hz. Only positive values are permitted

• duty_cycle – Duty Cycle for the square wave. Only values 0.0 <= DutyCycle <= 1.0 is permitted

Returns:

Returns one sample for current system time

Example

Listing 73 Example function call to square wave generator

#include "uz_wavegen.h"
int main(void) {
   float amplitude = 6.0f;
   float frequency_Hz = 20.0f;
   float duty_cycle = 0.5f;
   float output = uz_wavegen_square(amplitude, frequency_Hz, duty_cycle);
}

Description

This function calculates a square wave based on the global system time.
