Actually, I solved this problem by using pwm driver.

Busy work is busy state in CPU.

Hi,

[quote user=""][/quote]

So I intergrated the example to my project. But I found out the bug in my project.

If I use pwm in the midst of busy work, I found the system die. I don't find any error code.

Could you give me more details on what you mean by "bug in your project"? What happens and when it happens? What do you mean by "busy work"?

The difference between the PWM driver and library is that the PWM driver (nrf_drv_pwm.c) uses the PWM peripheral, while the PWM library(app_pwm.c) uses the TIMER, PPI and GPIOTE peripherals. The PWM driver uses dedicated hardware to generate the signal, while the PWM library uses GPIOTE, PPI and timers in combination.
