compilation problem with Bluefruit / Arduino

[Vincent25]

Hi,
I want to use the SAADC of the NRF52832

The board is Adafruit/ Bluefruit Feater.

The compiler is Arduino EDI

I need to access to all the registers of the board or i need in fact to access to all the parameters of the ADC
I think it's not possible with the hi level api of bluefruit.
so i try to use the driver of nordic.
the header of the functions are defines in the package installed :
C:\Users\F085404\AppData\Local\Arduino15\packages\adafruit\hardware\nrf52\0.14.6\cores\nRF5\nordic\nrfx\drivers\include

is it possible to access to nrfx_saadc.h?
i have some error of the linker which cannot find the functions called:

C:\Users\F085404\Documents\Arduino\test_saadc_nordic/test_saadc_nordic.ino:48: undefined reference to `nrfx_saadc_init'
(this function is defined in nrfx_saadc.h)
maybe i need the source to compile it...
thank you.

Hi, 

If you look at our official SDK, which you can find here, you will see nrfx_saadc.h found in SDK\modules\nrfx\drivers\include

Thank you Amanda, 

I think my explainations were not very clear.

i have the SDK\modules\nrfx\drivers\include\nrfx_saadc.h

but i haven't the file .C in which there is the develepment of the function.

Is it normal?

is it possible to compile with only the header file .

Maybe i need an .obj at least?

thank you

Vincent

You could find nrfx_saadc.c under \nRF5_SDK\modules\nrfx\drivers\src
