Tógálaí Ranga #

led(
  triport::port &port );

Scriostóir Ranga #

Scriosann sé an réad led agus scaoileann sé acmhainní gaolmhara.

Paraiméadair #

Paraiméadar	Cineál	Cur síos
`port`	`triport::port &`	An Port 3-Sreang a bhfuil an Táscaire LED ceangailte leis, scríofa mar `Brain.ThreeWirePort.X` nó `ExpanderName.X`, áit a seasann `X` do litir an phoirt (mar shampla, `Brain.ThreeWirePort.A` nó `Expander1.A`).

Samplaí #

// Create an led instance in Port A
led LEDA = led(Brain.ThreeWirePort.A);

Feidhmeanna na mBall #

Áirítear leis an rang led na feidhmeanna ball seo a leanas:

on — Casann sé an Táscaire LED sonraithe air.
off — Múchann sé an Táscaire LED sonraithe.

Sula nglaotar ar aon fheidhmeanna led ball, ní mór sampla led a chruthú, mar a thaispeántar thíos:

/* This constructor is required when using VS Code.
LED Indicator configuration is generated automatically
in VEXcode using the Device Menu. Replace the values
as needed. */

// Create an led instance in Port A
led LEDA = led(Brain.ThreeWirePort.A);

on #

Casann sé an Táscaire LED sonraithe air.
