  :caption: Example function call to sawtooth wave generator with offset

  #include "uz_wavegen.h"
  int main(void) {
     float amplitude = -5.0f;
     float frequency_Hz = 10.0f;
     float offset = 1.0f;
     float output = uz_wavegen_sawtooth_with_offset(amplitude, frequency_Hz, offset);
  }

Description
===========

This function calculates a sawtooth with specified offset based on the global system time.
