[M1] PWM structural body

Pwm_config.mode = pwm_mode_led_255; 8-bit resolution, 122Hz PWM frequency, 32kHz timer [M1] Frequency (prescaler 9)

[M1] Setting the PWM mode

Pwm_config.num_channels = 2;

Pwm_config.gpio_num[0] = led_0; This is set to use which IO port as the PWM output

PWM_CONFIG.GPIO_NUM[1] = led_1; This setting uses which IO port to use as the PWM output [M1]

[M1] PWM two channels

Nrf_pwm_init (&pwm_config); PWM initialization [M1]

[M1] Initialize PWM

Nrf_pwm_set_value (0, T); [M1]

[M1] Set the duty ratio of channel 0 to T, full to 255, see mode above
