dac_sinewave

Overview

The dac_basic example shows how to use DAC module to generate sinewave.

The user can specify the sinewave frequency and how many output points in one cycle of the sinewave. Based on these two parameters and the functional clock frequency of ctimer, we can calculate how long each interval enters the ctimer interrupt.

Note: If the device does not have an FPU, then running the example directly may get bad performance, and the user can add an array, the elements of the array are the input values corresponding to the DAC output voltage values for one sinewave cycle.
