23.8.1.1.3 Workflow
- Create a PINMUX module pin configuration struct, which can be filled out to adjust the configuration of a single port pin.
struct
system_pinmux_config config_pinmux;
- Initialize the pin configuration struct with the module's default values.
system_pinmux_get_config_defaults(&config_pinmux);
Note: This should always be performed before using the configuration struct to ensure that all values are initialized to known default settings. - Adjust the configuration struct to request an input pin with pull-up connected to the GPIO peripheral.
config_pinmux.mux_position = SYSTEM_PINMUX_GPIO;
config_pinmux.direction = SYSTEM_PINMUX_PIN_DIR_INPUT;
config_pinmux.input_pull = SYSTEM_PINMUX_PIN_PULL_UP;
- Configure GPIO10 with the initialized pin configuration struct, to enable the input sampler on the pin.
system_pinmux_pin_set_config(10, &config_pinmux);
