数字输出 #

介绍 #

The digital_out class is used to control digital output signals on a VEX V5 3-Wire port. It allows a device to set a connected output to either a high or low state.

类构造函数 #

digital_out( 
  triport::port &port );

类析构函数 #

Destroys the digital_out object and releases associated resources.

~digital_out();

参数 #

范围	类型	描述
`port`	`triport::port &`	The 3-Wire Port that the Digital Output device is connected to, written as `Brain.ThreeWirePort.X` or `ExpanderName.X`, where `X` is the port letter (for example, `Brain.ThreeWirePort.A` or `Expander1.A`).

例子 #

// Create the digital_out instance on 3-Wire Port A
digital_out DigitalOutA = digital_out(Brain.ThreeWirePort.A);

成员功能 #

The digital_out class includes the following member functions:

set — Outputs a high or low signal to the connected Digital Out device.

Before calling any digital_out member functions, a digital_out instance must be created, as shown below:

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

// Create the digital_out instance on 3-Wire Port A
digital_out DigitalOutA = digital_out(Brain.ThreeWirePort.A);

set #

向连接的数字输出设备输出高电平或低电平信号。

Available Functions

  bool value );

Parameters

范围	类型	描述
`value`	`bool`	Whether to send a high or low signal: `true` – Send a high signal (5V) `false` – Send a low signal (0V)
