Software Description
GPIOs Configuration
To set a GPIO to analog mode check the check box from the “GPIO mode” group box. If left unchecked, then the GPIO is a digital output or input, depending on the state of the
“GPIOx enable output” check boxes - unchecked means the pin is digital input. If the pin is set as digital output, it’s state can be set via the corresponding check box in the “Output state” group box.
