in gpio_init():
NRF_GPIOTE->CONFIG[0] = (GPIOTE_CONFIG_POLARITY_Toggle << GPIOTE_CONFIG_POLARITY_Pos)
| (0 << GPIOTE_CONFIG_PSEL_Pos)
| (GPIOTE_CONFIG_MODE_Event << GPIOTE_CONFIG_MODE_Pos);
the 0 should be changed to BUTTON_0 like this:
NRF_GPIOTE->CONFIG[0] = (GPIOTE_CONFIG_POLARITY_Toggle << GPIOTE_CONFIG_POLARITY_Pos)
| (BUTTON_0 << GPIOTE_CONFIG_PSEL_Pos)
| (GPIOTE_CONFIG_MODE_Event << GPIOTE_CONFIG_MODE_Pos);
Well for the nRF6310 it doesn't matter, but it's a bit confusing if someone try to port this tiny example to a different board.
