pwm

[D]

Hi every body,

There is a problem with pwm driver example in demo3 part! after downloading, the board led is just on as it must, but after changing top_value there is no changing in led brightness!

If somebody know, please let me know how to change the brightness?

Kind regards

i saw your post before which it was about set a fixed duty cycle

This one: https://devzone.nordicsemi.com/f/nordic-q-a/38607/nrf5-sdk15-0---pwm-driver-just-set-a-fixed-duty-cycle ?

So did you see what I said about setting top_value = 0x8000 ?

After put the code instead of the demo3 and decreasing the top_value i expected to observe changing in led brightness. But nothing happened. I want to know know how to change the led intensity brightness.

No.

The "top" value sets the period - it's the duty cycle that you need to vary.

Thank you awneil. it worked.

may I know where to change the duty cycle? The documentation is kinda hard to read and understand.
