App Timer not run with PWM driver simultaneously

Just to clarify:

If you call pwm_init() after app_timer_init() and app_timer_start, then both PWM and app timer works fine. But when it is called before then only PWM works. Is this correct? What kinda error do you get when program hang?

yes, it success, if it error, program will hang. But it run PWM normal, it only not run timer.

Hi,

Seems like you worked it out?

Not too sure why the order would be an issue. When you get initiate the PWM first, what do you get as return code on app_timer_init() and app_timer_start()? Are they called successfully?

Hi,

If I change

APP_ERROR_CHECK(app_timer_init());
create_timers();
int err_code = app_timer_start(m_repeated_timer_id, APP_TIMER_TICKS(200), NULL);
APP_ERROR_CHECK(err_code);
pwm_init(LED_1, LED_3);

It run PWM and Timer but

pwm_init(LED_1, LED_3);
APP_ERROR_CHECK(app_timer_init());
create_timers();
int err_code = app_timer_start(m_repeated_timer_id, APP_TIMER_TICKS(200), NULL);
APP_ERROR_CHECK(err_code);

It only run PWM.

And I don't understand why.

Hi,

Can you try debug the code and see if you are getting any error codes when running both at the same time? Do you have any logs?
