RE: GPIOTE Set/Clr vs. Out task

Worked perfectly fine. And I see, taking a look at the nrfx_gpiote.c code why. In nrfx_gpiote_output_configure(), there's the block:

        nrf_gpiote_te_default(NRF_GPIOTE, ch);
        m_cb.pin_flags[pin] &= ~(PIN_FLAG_TE_USED | PIN_TE_ID_MASK);
        if (p_task_config->polarity != NRF_GPIOTE_POLARITY_NONE)
        {
            nrf_gpiote_task_configure(NRF_GPIOTE, ch, pin,
                                      p_task_config->polarity,
                                      p_task_config->init_val);
            m_cb.pin_flags[pin] |= PIN_FLAG_TE_ID(ch);
        }
    }

That conditional if statement on the third line is stopping my setup. Probably an oversight in the library, but at least it all makes sense. Thanks!

Hi Kevin,

Could you try to set the .polarity field to NRF_GPIO_POLARITY_NONE when you use the set and clear tasks?

Please try this and let me know how it goes.
