PRESSURE_CONFIG[:port]

Class Method Summary

• .detect(options = {}, &block) ⇒ Array

  Detects and returns information from the Pressure driver.

• .detect_once ⇒ Hash

  Detects one response from the Pressure driver and returns its value.

Class Method Details

.detect(options = {}, &block) ⇒ Array

Detects and returns information from the Pressure driver

Examples:

Detect 3 values for the Pressure driver

MatrixCreator::Pressure.detect(max_resp: 3)

Detect values for the Pressure driver for 30 seconds

MatrixCreator::Pressure.detect(max_secs: 30)

Detect values for the Pressure driver with a speed of 0.5 seconds per response

MatrixCreator::Pressure.detect(max_secs: 30, speed: 0.5)

Detect values for the Pressure driver for 15 seconds and process data when received

MatrixCreator::Pressure.detect(max_resp: 10){ |data|
  // Do something with the data
}

Parameters:

• options (Hash) (defaults to: {}) —

  of keys and values that can contain speed, max_resp and/or max_secs

Returns:

• (Array) —

  elements detected in JSON format

def self.detect(options = {}, &block)
  MatrixCreator::DriverBase.detect(BASE_PORT, MatrixMalos::Pressure, options, block)
end

.detect_once ⇒ Hash

Detects one response from the Pressure driver and returns its value

Returns:

• (Hash) —

  object with the Pressure response values

# File 'lib/matrix_creator/pressure.rb', line 44

def self.detect_once
  detect(max_resp: 1).first
