Hi Maria,

Thank you for your reply.

I've solved the problem.I have used nrfx_gpiote_out_task_force.

nrfx_gpiote_out_set and nrfx_gpiote_out_clear cannot change the pin status.

Hello,

Please write your questions in english.

TIMER0 is used by MPSL, so who uses TIMER1? Is it 802154?

TIMER1 is used by the 802.15.4 radio driver, yes. See the dependency for CONFIG_NRF_802154_RADIO_DRIVER here.

See the GPIOTE driver and the functions nrfx_gpiote_out_set and nrfx_gpiote_out_clear.

Best regards,

Maria

你好，玛丽亚，

谢谢你的回答。

TIMER0 由 MPSL 使用，那么谁使用 TIMER1？是 802154 吗？

Have you considered using the Zephyr kernel timers? If not I suggest that you read on them in the Timers and Kernel Timing sections of the Zephyr documentation. From what I can see, the Zephyr timers can be used for the functionality you need. [/quote]

I need a very precise time interval, so I think the only way is to use the timer irq.

I have another urgent problem.

Hello,

I have done some investigation about the ownership of peripherals for OpenThread application in NCS. Multiprotocol Service Layer (MPSL) is required for OpenThread on nRF5x devices in NCS and owns the following peripherals for nRF52 series:

The screenshot is from the Integration notes for MPSL.

Regarding your timer. Have you considered using the Zephyr kernel timers? If not I suggest that you read on them in the Timers and Kernel Timing sections of the Zephyr documentation. From what I can see, the Zephyr timers can be used for the functionality you need.

[quote user=""]When I enable CONFIG_NRFX_TIMER0=y in prj.conf, the system starts up with an error.[/quote]

This is expected because MPSL owns TIMER0.

Does your .overlay file meet one of the requirements from the Set Devicetree overlays section of Devicetree HOWTOs?

Best regards,
