Maybe I should post my all the code here.
I want to generate two kinds of PWM1 and PWM2,used by the code as follows: static volatile bool ready_flag;
APP_PWM_INSTANCE(&PWM1,1); APP_PWM_INSTANCE(&PWM2,2);
void pwm1_ready_callback(void) { ready_flag = true;//This code may be unuseful,but it comes from the Nordic Demo. }; void pwm2_ready_callback(void) { ready_flag = true;//This code may be unuseful,but it comes from the Nordic Demo. };
One of them is initialized by the code as follows:
void pwm_ble_led(void) { static ret_code_t error_code; app_pwm_config_t pwm1_cfg = APP_PWM_DEFAULT_CONFIG_1CH(1000000,LED_0); pwm1_cfg.pin_polarity[0] = APP_PWM_POLARITY_ACTIVE_LOW; error_code = app_pwm_init(&PWM1,&pwm1_cfg,pwm1_ready_callback); APP_CHECK_ERROR(error_code); }
The another as the same,the code as follows:
void pwm_power_ble(void) { static ret_code_t error_code; app_pwm_config_t pwm1_cfg = APP_PWM_DEFAULT_CONFIG_1CH(1000000,LED_1); pwm1_cfg.pin_polarity[0] = APP_PWM_POLARITY_ACTIVE_HIGH; error_code = app_pwm_init(&PWM2,&pwm1_cfg,pwm2_ready_callback); APP_CHECK_ERROR(error_code); }
The PWM closed code as follows:
void pwm_ble_close(void)
{
uint32_t err_code;
app_pwm_disable(&PWM1);
nrf_drv_gpiote_out_task_disable(LED_0);
err_code = app_pwm_uninit(&PWM1);
APP_ERROR_CHECK(err_code);
}
void pwm_power_close(void) { uint32_t err_code; app_pwm_disable(&PWM2); nrf_drv_gpiote_out_task_disable(LED_1); err_code = app_pwm_uninit(&PWM2); APP_ERROR_CHECK(err_code); }
The PWM start working code as follows:
void pwm_ble_led_start(void) { pwm_ble_close();//this code is used for guaranting that the PWM is closed,otherwise the system would reset. pwm_ble_led(); app_pwm_enable(&PWM1); nrf_drv_gpiote_out_task_enable(LED_0); app_pwm_channel_duty_set(&PWM1,0,50); }
void pwm_power_led_start(void) { pwm_power_close(); pwm_power_led(); app_pwm_enable(&PWM2); nrf_drv_gpiote_out_task_enable(LED_1); app_pwm_channel_duty_set(&PWM2,0,50); }
The question is how to control the two PWM independently?I have tried the function of app_pwm_disable() and app_pwm_uninit(),but it does not work result of influencing the another PWM.
