Hi
I want to generate two PWM signals that are phase shifted with 90 degree, with similar duty cycle. I have the following pwm configuration, but I don't know how to proceed further. I would be more than happy if someone could give me some help. I would appreciate if someone could send me a link to an example, if exists.
nrf_drv_pwm_config_t const pwm_cfg = { .output_pins = { 9, // channel 0 10, // channel 1 NRF_DRV_PWM_PIN_NOT_USED, // channel 2 NRF_DRV_PWM_PIN_NOT_USED, // channel 3 }, .irq_priority = APP_IRQ_PRIORITY_LOWEST, .base_clock = NRF_PWM_CLK_1MHz, .count_mode = NRF_PWM_MODE_UP, .top_value = 100, .load_mode = NRF_PWM_LOAD_INDIVIDUAL, .step_mode = NRF_PWM_STEP_AUTO }; APP_ERROR_CHECK(nrf_drv_pwm_init(&m_pwm0, &pwm_cfg, NULL)); // This array cannot be allocated on stack (hence "static") and it must // be in RAM (hence no "const", though its content is not changed). static nrf_pwm_values_individual_t seq_values[] = {25, 25, 0, 0}; nrf_pwm_sequence_t const seq = { .values.p_individual = seq_values, .length = NRF_PWM_VALUES_LENGTH(seq_values), .repeats = 0, .end_delay = 0 }; nrf_drv_pwm_simple_playback(&m_pwm0, &seq, 5, NRF_DRV_PWM_FLAG_STOP);
p.s I am using sdk.v14
Thanks in advance
