App timer library setup problems

What toolchain/IDE are you using? SES? Have you also added the path to the folder containing source, and added the source file as part of the project? See this.

Hi Jared!

Added the new line (// <q> CLOCK_CONFIG_LF_CAL_ENABLED - Calibration enable for LF Clock Source) to the sdk config, however, nothing better, can you say more about the following?

[quote userid="73165" url="~/f/nordic-q-a/89000/app-timer-library-setup-problems/374318"]App timer source file and path to source file has also been added to the project right?[/quote]

And this are my includes:

// app timer library
#include "nrfx_timer.h"
#include "bsp.h"
#include "nrf_drv_timer.h"

#include "app_timer.h"
#include "nrf_drv_clock.h"

So far I have the nrfx_timer.c in the nRF_Drivers folder and app_timer.c in the nRF_Libraries folder.

Is this ok?

Best.

Hi,

Are you still getting the same error? Could you try to also add this:

// <e> NRF_CLOCK_ENABLED - nrf_drv_clock - CLOCK peripheral driver - legacy layer
//==========================================================
#ifndef NRF_CLOCK_ENABLED
#define NRF_CLOCK_ENABLED 1
#endif
// <o> CLOCK_CONFIG_LF_SRC  - LF Clock Source
 
// <0=> RC

// <2=> Synth 
// <131073=> External Low Swing 
// <196609=> External Full Swing 

#ifndef CLOCK_CONFIG_LF_SRC
#define CLOCK_CONFIG_LF_SRC 1
#endif

// <q> CLOCK_CONFIG_LF_CAL_ENABLED  - Calibration enable for LF Clock Source
 

#ifndef CLOCK_CONFIG_LF_CAL_ENABLED
#define CLOCK_CONFIG_LF_CAL_ENABLED 0

// <7=> 7 

#ifndef CLOCK_CONFIG_IRQ_PRIORITY
#define CLOCK_CONFIG_IRQ_PRIORITY 6
#endif

// </e>

App timer source file and path to source file has also been added to the project right?

regards

Jared

Hello Jared,

was missing this, so I have put the following into the sdk_config.h

// <e> NRFX_CLOCK_ENABLED - nrfx_clock - CLOCK peripheral driver
//==========================================================
#ifndef NRFX_CLOCK_ENABLED
#define NRFX_CLOCK_ENABLED 1
#endif

// <o> NRFX_CLOCK_CONFIG_LF_SRC  - LF Clock Source

// <0=> RC 
// <1=> XTAL 
// <2=> Synth 
// <131073=> External Low Swing 
// <196609=> External Full Swing 

#ifndef NRFX_CLOCK_CONFIG_LF_SRC
#define NRFX_CLOCK_CONFIG_LF_SRC 1
#endif

// <o> NRFX_CLOCK_CONFIG_IRQ_PRIORITY  - Interrupt priority
 
// <0=> 0 (highest) 
// <1=> 1 
// <2=> 2 
// <3=> 3 
// <4=> 4 
// <5=> 5 
// <6=> 6 
// <7=> 7 

#ifndef NRFX_CLOCK_CONFIG_IRQ_PRIORITY
#define NRFX_CLOCK_CONFIG_IRQ_PRIORITY 6
#endif

I guess this is ok now ? Anyway, it compiles with no warnings, however, still getting the error when trying to run the lfclk_request();

Any ideas how to get around with the SDK that I am using?

Best.

Hi,

[quote user=""] I guess it is not a problem of using a different SDK? [/quote]

It is!

The blog post was made for an earlier version of the SDK, thus changes to later versions will affect it. Have you enabled the nrfx_clock driver by setting

NRFX_CLOCK_ENABLED 1 in the sdk_config.h file?
