Application: Using PWM0 Channel 0 (PA.5) and RC low-pass filter to generate 60 Hz sine wave for application.
BSP Version: M031 Series BSP CMSIS V3.02.000
Hardware: NuMaker-M032SE V1.3
This example code uses M031 PWM0 Channel 0 (PA.5) to generate 60 Hz sine wave. To generate high-resolution sine wave, a single sine wave will have 360 points. Based on sine value calculation and PWM period value, each point has different PWM duty value. Then PWM changes the duty value according to each point value and sine wave frequency. By using external RC filter, PWM output would be smooth sine wave.
