nRF52 SDK Architecture overview

[Prasad PL]

Hi Nordic Team,

I am requesting any block diagram level documentations - on a high level software architecture overview of SDK.

My goal is to understand how different layers of drivers are interconnected.

main->app_uart->app_uart_fifo->nrf_drv_uart->nrfx_uart->nrfx_uarte->nrfx and so on.

The same layers app, nrf, nrfx can be observed in twi and implementing other peripherals.

Same is the case with ble drivers

Is there any quick read documentation of overview on this architecture and relationships ?

Have you looked at the info center yet? http://infocenter.nordicsemi.com/index.jsp

[Prasad PL]

Yes I have. Curious anything specifically for nRF52 SDK - like ppt presentation /bootcamp/workshop ?

so I can get a quick overview ?

Now I am learning all highlevel relationships - literally tracing the code flow in the codebase.

Was hoping if there was a faster method.

my guess is they do have some material like that but probably not much. for the most part I believe the flow is application -> nrf libs -> nrf drv -> nrfx.

sounds like you already have a good feel for the architecture though. Perhaps go back to the older sdks and the nrf51 examples which were a lot easier to flow than the present ones. That may help you build a better base line for getting comfortable with the newer scheme.
