system.oob.gpio

Abbreviation

sy o g

Access

get/set

Description

The system.oob variables allow creation of an out-of-band interrupt (OOB) GPIO. This GPIO is asserted whenever one or more of the configured OOB events occurs. It is de-asserted when reading the OOB status register.

Note : OOB events are in most cases related to a corresponding special function GPIO variable. However, the OOB event can be configured without setting the corresponding special function GPIO.

Specify the OOB GPIO with the system.oob.gpio variable.

Specify the active level of the OOB GPIO with system.oob.gpio_level .

Specify the events that cause the OOB GPIO to be asserted with system.oob.event_mask .

Specify events that trigger the OOB GPIO only on the rising edge (i.e. when the event is asserted) with system.oob.rising_edge_mask .

Read the events that triggered an OOB interrupt from the system.oob.status variable.

Only one GPIO can be specified as the OOB GPIO. Determine the OOB GPIO by reading the gpio.usage variable or the system.oob.gpio variable.

Events are mapped to the event mask , rising edge mask and status mask as shown in the following table:

OOB Event Name Mask Value
ioconn.status_gpio 0x001
tcp.server.connected_gpio 0x004
tcp.server.data_gpio 0x008
HTTP data ready (see http_get , http_post commands) 0x400

Arguments

<GPIO #> The number of the OOB GPIO.

Default

No GPIO assigned to OOB

Set example

> set sy o l 0
Set OK

system.oob.rising_edge_mask

Abbreviation

sy o r

Access

get/set

Description

The mask of events which should trigger the OOB GPIO only on the rising edge (i.e. when an event is asserted). See system.oob.gpio .

If the mask is cleared, then the OOB GPIO is asserted on both rising and falling edges.

For instance, when the module connects, the network status event event is considered asserted. When the module disconnects, the event is considered de-asserted.

For event/mask mapping, see the system.oob.gpio event mask table .

Arguments

<hex mask> Mask is specified in the form 0xHH where H is a hexadecimal digit 0-F.

Default

0x0

Properties

Supported Platforms

Get example

> get sy o r
0x1F

Set example

> set sy o r 0x11
Set OK

system.oob.status

Abbreviation

sy o s

Access

get

Description

The mask of triggered events. When an event is triggered, the OOB GPIO is asserted and the status mask is updated with the triggering event. Reading this variable returns a mask of events that caused the OOB gpio to be asserted.

Reading this variable de-asserts the OOB GPIO and clears the status mask.

For event/mask mapping, see the system.oob.gpio event mask table .

Arguments

-

Default

0x0

system.safemode.disabled

Abbreviation

sy d

Access

get/set

Description

Disables safe mode feature when set to true . When safe mode is disabled and 8 or more faults occur, Gecko OS automatically resets the fault counter and runs the boot application. It is strongly recommended to leave this setting false as it may not be possible to recover from a fatal error.

Note : A factory reset returns this setting to the default state of false .

Arguments

<true/1/0/false>

0
