GPTIOTE TASK WITH THE SAME IO

[Joseph]

Hello,

Can I assign two GPIOTE tasks to work with the same output port? One to set it high, another to set it low.

Here is the code segment: nrf_gpiote_task_config(ch0,port0,NRF_GPIOTE_POLARITY_HITOLO,NRF_GPIOTE_INITIAL_VALUE_HIGH); nrf_gpiote_task_config(ch1,port0,NRF_GPIOTE_POLARITY_LOTOHI,NRF_GPIOTE_INITIAL_VALUE_HIGH); NRF_GPIOTE->TASKS_OUT[ch0] = 1; NRF_GPIOTE->TASKS_OUT[ch1] = 1;

I am testing with a "C0" version of 51822 and the above code seems doesn't work. Please advise.

Thank you! Joseph

Hi Joseph

Unfortunately this is a limitation in the GPIOTE. You can only have one output channel assigned to each IO.

This means that you have to use the toggle option if you need to both set and clear an output.
