Application: This code uses MS51 PWM Channel 0 (P1.2), Channel 1 (P1.1) and Channel 2 (P1.0) to generate 60 Hz three phase sine wave for application.
BSP Version: MS51 Series BSP Keil V1.00.002
Hardware: NuTiny-MS51FB V1.1
This example code uses MS51 PWM Channel 0 (P1.2), Channel 1 (P1.1) and Channel 2 (P1.0) to generate 60 Hz 3 phase sine wave for application, such as motor control. 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.
