Configuration of GPIO as an output
|
|
|
|
.. code-block:: c
|
|
|
|
gpio_config_t io_conf;
|
|
io_conf.intr_type = GPIO_INTR_DISABLE; //disable interrupt
|
|

|
|
io_conf.pin_bit_mask = GPIO_SEL_18 | GPIO_SEL_19; //bit mask of the pins that you want to set,e.g.GPIO18/19
|
|
io_conf.pull_down_en = 0; //disable pull-down mode
|
|
io_conf.pull_up_en = 0; //disable pull-up mode
|
|
gpio_config(&io_conf); //configure GPIO with the given settings
|

|
|
|
.. code-block:: c
|
|
|
|
gpio_config_t io_conf;
|
|
io_conf.intr_type = GPIO_INTR_POSEDGE; //set posedge interrupt
|
|

|
|

|
|
io_conf.pull_down_en = 0; //disable pull-down mode
|
|
io_conf.pull_up_en = 1; //enable pull-up mode
|
|
gpio_config(&io_conf); //configure GPIO with the given settings
