RE: button handler interrupt - nrf52840 dongle

Maboo — Wed, 13 Jan 2021 10:12:22 GMT

Ok, it took me a while. I solved the problem with GPIOTE

I added to the Makefile:

$(SDK_ROOT)/modules/nrfx/drivers/src/nrfx_gpiote.c \

The relevant parts of my code:

#include "nrf_drv_gpiote.h"
#include "nrf_delay.h"

...

static void gpio_init(void)
{
    nrf_drv_gpiote_init();    
    nrf_drv_gpiote_out_config_t out_config = GPIOTE_CONFIG_OUT_SIMPLE(true);
    nrf_drv_gpiote_out_init(BSP_LED_1, &out_config);
    nrf_drv_gpiote_out_init(BSP_LED_2, &out_config);  
    nrf_drv_gpiote_out_init(BSP_LED_3, &out_config);
    nrf_drv_gpiote_out_init(BSP_LED_4, &out_config); 
}

...

int main(void)
{
    while(true)
    {
        nrf_drv_gpiote_out_toggle(BSP_LED_1);
        nrf_delay_ms(500);
        nrf_drv_gpiote_out_toggle(BSP_LED_2);
        nrf_delay_ms(500);
        nrf_drv_gpiote_out_toggle(BSP_LED_3);
        nrf_delay_ms(500);
        nrf_drv_gpiote_out_toggle(BSP_LED_4);
        nrf_delay_ms(500);
    }
    

}

Have a nice day!

Thank you very much for your help awneil. I will try it out. Have a nice day!

The ones under 'Hardware peripheral examples' just use the microcontroller's hardware peripherals - no BLE

the main thing is that you get the debugger, and most of the examples are focussed on the DK

you also get more LEDs and buttons, and breakouts of all the chip's pins

...and can you please recommend an example to start with?

I use nrf connect programmer, if thats what you mean? Ok, you convinced me, I own a DK so I going to test it there first. Could you explain why would it make this all much easier? I mean, yes it can debug but in the end I want to use this program on my nrf dongle.

you must have missed something.

I don't think it's worth the effort trying to pursue it - just start from an example that is designed to work without the SoftDevice!

Are you programming the device via the bootloader? I'm not sure if that has any dependencies on the SD ...

Again, a DK would make this all so much easier.

Thanks for your quick response.

That is all the code I use, I striped the ble_app_blinky example, deleted all sdh includes and tested it as it is.

Switching on a LED in my main works, but not in button_handler. Can it have something to do with my makefile or sdk_config.h, do i have to enable or disable something?

It would be a lot easier to start on a Development Kit (DK) - rather than the dongle.

[quote userid="94551" url="~/f/nordic-q-a/67414/button-handler-interrupt---nrf52840-dongle"]is there a way to get this code running without any softdevice? [/quote]

yes: the SDK has examples of using the chip as just a microcontroller - with no BLE

[quote userid="94551" url="~/f/nordic-q-a/67414/button-handler-interrupt---nrf52840-dongle"]why is it just working with it?[/quote]

What else is in your code? Is it getting stuck in something which does require the softdevice?
