HI，Jared:

    yes!Just I want more high frequency.But when i change the Frequency with my purpose,shall i change the timer_ms?

But when i change it,the frequency makes farely changes!  And   it seems usefulless when i use the function "nrf_timer_frequency_set()". Even it is useless doing setting in sdk_config.h.

And,en,by the way, could we communicate with wechat?QQ,or skype? It would be more efficiently！

Hi,

I'm not sure I understand your question correctly. But nrf_drv_timer_ms_to_ticks(&TIMER_LED, time_ms) converts the period to number of ticks. What are you changing it from and to?

I want to use timer1 to generate frequency from 10kHz to 50kHz,But from app_hid_mouse example,I only get 500Hz more than a little. And,amog the timer example you mentioned above,it can generate 20kHz.

This morning，I use nrf_drv_timer  to generate 50Khz。I  was amazing,what's the the deference between nrfx_timer   and nrf_drv_timer?

Hi,

nrfx_driver is legacy while the nrf_driver is what you should use in your projects.
