Adding PWM Driver to ble_blinky_central example

[ashokr.com]

Hi All,

I created one channel PWM from pwm_drive example and its works well.

Now i m trying to add the PWM functions ...into my ble_blinky_central example.

Compilations fine but during run time Fault handler error at ->     nrf_pwm_configure(p_instance->p_registers,
        p_config->base_clock, p_config->count_mode, p_config->top_value);

no clue why this is happening ...

attached  the sdk_config.h for reference sdk_config.h

thanks

Ashok

Hi,

Could you set a breakpoint where you get the error and share the values of the parameters from debug view?

Hi Jared,

One more thing i tried to add PWM in ble peripheral -> ble_app_template example and works but with central not woking.

I have attached here the updated sdk_5327.sdk_config.hconfig.h

ERROR: ID = 4001

Hi,

What Softdevice and board are you using?

I'm sorry I should have elaborated a bit more on my previous reply, the debug terminal should print what file and line number that you're getting the error at if you define the #DEBUG flag in the preprocessor defines. See this similar thread if you're unsure on how to define it.

Hi JaFF0000,

Point 1: Some times i did not see replay option here for the latest thread. -> for community developer

Point 2:  Debug Prints -> example NRF_LOG_() i have no idea where this gets printed, really worried for this kind of complexity with nordic SDK. 

Expectation is : any example if i open and run, i should see the prints out in debug console without doing any circus with configuration.

I struggled but completed my work without using any console print outs. The reason is SDK and implementation was awesome.

Still, Nordic should think of handling the sdk_config.h file better way in future.

Point3: PWM now works with the app_pwm.c file , earlier i tried with driver files where i got trapped. I can suggest how we can reproduce the issue on your end.

1.Take any ble_client example projects , add PWM drivers to that then you see the issue.

Thanks
