Táscaire LED#

Réamhrá#

Leis an rang led , is féidir leis an V5 Brain dé-óid astaithe solais (LED) ceangailte a chasadh air nó as ag baint úsáide as Port 3-Sreang.

An táscaire LED glas VEX V5.

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.
