Output configura on for GPIO4:
Jack 3.5 mm GPIO4 configura on
The GPIO configura on des GPIOs can be realized by edi ng some user preferences in the device configura on Web interface or thanks to a configura on script.
How to configure the Jack 3.5 mm connector:
//Set Jack 3.5 mm mode infrared
if (aDirection == "disable")
{
Services.prefs.setBoolPref("system.connector.jack35_1.1.io.uart_1.enabled", true);
}
else //Set Jack 3.5 mm mode GPIO
{
Services.prefs.setBoolPref("system.connector.jack35_1.1.io.uart_1.enabled", false);
}
// Set the Jack 3.5 mm direction: input or output
if (aDirection == "out")
{
Services.prefs.setBoolPref("innes.app-profile.gpio-input.jack35-gpio_1.jack35_1.*.authorized", false);
Services.prefs.setBoolPref("innes.app-profile.gpio-output.jack35-gpio_1.jack35_1.*.authorized", true);
Services.prefs.setBoolPref("system.connector.jack35_1.1.io.jack35-gpio_1.enabled", true);
}
else if (aDirection == "in")
{
Services.prefs.setBoolPref("innes.app-profile.gpio-input.jack35-gpio_1.jack35_1.*.authorized", true);
Services.prefs.setBoolPref("innes.app-profile.gpio-output.jack35-gpio_1.jack35_1.*.authorized", false);
Services.prefs.setBoolPref("system.connector.jack35_1.1.io.jack35-gpio_1.enabled", true);
}
else if (aDirection == "disable")
{
Services.prefs.setBoolPref("innes.app-profile.gpio-input.jack35-gpio_1.jack35_1.*.authorized", false);
Services.prefs.setBoolPref("innes.app-profile.gpio-output.jack35-gpio_1.jack35_1.*.authorized", false);
Services.prefs.setBoolPref("system.connector.jack35_1.1.io.jack35-gpio_1.enabled", false);

Phoenix connector
The Phoenix connector has 2 func ons:
the capability to drive with the GPIO1 a internal relay, allowing for example to open or close a electric door,
the capability to drive a peripheral or get the state of another peripheral thank to the GPIO2 and GPIO3.
