Porting embOS for NRF SDK. Definition configTICK_SOURCE (RTC1_IRQHandler).

[VadymS]

Hi.

I am working in company for medical devices. And we test the embOS RTOS to use in the product. Reason: the device must be compliance to Medical Safety standard.

I took the peripheral UART example, added the embOS and it started to work. Now I am working on adding Soft Device and BLE to the project.

1. Do you have an example of the porting for embOS? Or example or code of somebody else for "app_timer" implementation?

2. Why the FreeRTOS uses FREERTOS_USE_RTC and  RTC1_IRQHandler for OS and SW Timers?

3. In embOS SysTick is used for RTOS. Can I use SYSTICK it or I need change it?

Thanks.

Hi.

1. No, I'm afraid we don't have any example "of the porting for embOS".

2. Softdevice uses RTC0, so freeRTOS uses RTC1.

3. You can use SYSTICK, but SYSTICK needs HFCLK and is not power friendly. Using RTC is good for power friendly systems as RTC only uses LFCLK in power save mode.
