while merging blinky + timer , found an error nrfx_config.h: No such file or directory

[ps_anu]

hi.........

 i am tried to merge the blinky and timer sample program , i am getting this error , even i have included all files .h , .c files

nrfx_config.h: No such file or directory

[rohit]

you have to link this file and enable driver into SDK_CONFIG.h file.

[ps_anu]

how  to do that 

[rohit]

click on this

2) 

3)

4)

5) And Add put your file path whatever you have to add in nrf_driver and nrf_liabrary section.

6) After that, you have to make changes in sdk_config.h f

7)

And enable it, If any file is not there then you have to configure in Text Editor.. as per your driver.

yes i did , but now i am getting error 

'm_led_a_timer_id' undeclared (first use in this function)

but i have declared this 

APP_TIMER_DEF(m_led_a_timer_id);

m_led_a_timer_id

search this function separately in timer example. if you find in other files, add this file with specific path.

please check this one also...

sometimes configuration is not available in "Configuration_wizard" you have to add into a text editor.

if it is not done, 

please send your ZIP file.

yeah sure ,  i am using embedded segger studio

[ps_anu]

  i tried .. i can't  able to figure out mistake . here i am dropping my zip file

thanks in advance

blinky_pca10040_s132.rar

[rohit]

which SDK are you using?

[ps_anu]

sdk 15.2 version ...

[rohit]

I am using SDK 15.2.0-PCA10040-S132

I merge Blinky code into timer code.

Its showing 0 error.
