cannot compile when adding necessary files for usbd cdc acm

[weizhen]

I get a lot of error after just adding usbd source code into makefile. error: unknown type name 'NRF_USBD_Type', error: 'USBD_INTEN_ENDISOIN_Msk' undeclared here (not in a function), error: 'NRF_USBD' undeclared (first use in this function). all kind of these undeclared issues. I already enabled usbd related defines in sdk_config.h file. Is there any idea what's wrong with it? I include part of my makefile and config files here.

Probably you haven't enabled the necessary options in the sdk_config.h file ?

Suggest you look at an example which uses USB CDC ACM to see what options it sets ...

[weizhen]

I checked the example project and enabled all usbd related options as same as the example

Hi,

I suspect the problem is that you get the wrong MDK files included. Looking at your Makefile you have not commented out the lines that include NRF52 in your CFLAGS and ASMFLAGS. And since this is added before DNRF52840_XXAA, it is used instead when selecting the correct header file for the chip. So you should comment out or remove the lines with "CFLAGS += -DNRF52" and "ASMFLAGS += -DNRF52". (It is not obvious, but NRF52 in this case refers to nRF52832, and not the nRF52 series in general.)
