5.3 Dongle
tab
The DONGLE tab (
) is where to set up and use two features embedded in the
module, the real-time clock (RTC), and the general purpose inputs/outputs pins.
The node time indicates the value of the internal RTC of the module. Press the GET TIME
button in the commands panel to know the actual time of the module. In order to modify the
time, write the new time in the node time panel and click the SET TIME button. The module
time can be synchronized with the PC time shown in the current time panel. In this case,
simply check the SET CURRENT option in the node time panel before pressing the SET
TIME button.
The module has 8 general purpose input/output pins that can be configured individually
either as input pin or as output pin. In order to know the actual configuration, press the GET
IO CFG button in the commands panel. If a pin is configured as input, the Input x (where x is
the number of the pin) appears in the input status panel with the respective check box
checked, and a red or a green LED is shown. the color of the LED specifies if in the module
pin is applied a high level (+3.3 V), in this case the LED is red, or a low level (GND) in this
case the LED is green.
If the pin is configured as output, the output x (where x is the pin number) is shown in the
input status panel, and the corresponding check box is unchecked. A toggle pushbutton is
than associated to each output, indicating if the correspondent pin in the module must be
set high (+3.3 V), in this case the pushbutton must be pressed before to press the set
outputs button in the commands panel, or must be set low (GND) releasing the pushbutton
before press the set outputs button in the commands panel.
