"integration/nrfx/legacy" directory in SDK 15.0

[Rob Philip]

I am porting software built with SDK 14.2 to SDK 15.0

It looks like some files have been moved from "components/drivers_nrf" to "integration/nrfx/legacy". The first one I've encountered is nrf_drv_clock.c but I see that there are others. 

Have these files/apis/whatever been deprecated? Are there "new" ways to do the things provided in these legacy files? I notice that (for example) many of the examples still use these "legacy" functions...

Any insights would be helpful.

Hi,

This is described in the release notes for SDK 15.0.0:

** Drivers and libraries **
 - The way peripheral drivers are handled in the SDK has been reorganized:
     - Replaced existing drivers with the "external" drivers from nrfx project. See github.com/.../README.md for more information on nrfx.
     - New drivers from nrfx are located in "..\modules\nrfx".
     - Drivers replaced by nrfx are removed from "..\components\driver_nrf".
     - A glue layer is added to make the nrfx driver compatible with SDK and the SoftDevice.

Best regards,
Jørgen

Aha. *now* I can reply. 

So it looks like the answer to my question is that there *is* a new way to do things. Presumably the old way will vanish at some point. 

However, the examples all appear to use the "old" /integration/nrfx/legacy drivers. Are there any examples (I'm particularly interested in uarts, SPI, SAADC and BLE) that use the reorganized format? 

[Jørgen Holmefjord]

Yes, you can read more about this in the SDK 15.0.0 migration guide as well.

There will be more examples migrated to using the new drivers in future SDK releases. In most cases, it should be sufficient to change the names of function calls and configurations as described in the migration guide.

If you are facing any issues, please post your question in a devzone question and we will help you resolve it!

I will have give that a try. I would have happily begun with the "integration" code, but it doesn't work for UARTE1

I get 

'NRF_UART1' undeclared here (not in a function); did you mean 'NRF_AAR_Type'?

'NRFX_UART1_INST_IDX' undeclared here (not in a function); did you mean 'NRFX_UART0_INST_IDX'?

when I try to define the UARTE1 structure 

SSI_NRF_SERIAL_UART_DEF(serial1_uart, 1);

[Jørgen Holmefjord]

There is no UART1 peripheral available, only UARTE1. Please make sure you set UART_LEGACY_SUPPORT 0 in sdk_config.h.

[Rob Philip]

Right - but it's a Nordic macro that is generating the error (i copied it to remove the "static")

Do you mean I should set UART_LEGACY_SUPPORT to zero or one?
