quanser.hardware.hil.read_analog

Reads the specified analog channels.

Syntax

[voltages, err] = board.read_analog(channels)

Description

Reads the specified analog channels immediately it returns a vector of voltages.

If no err output is provided then it throws an exception if an error occurs. In generated code it prints the error message. Use hil_get_error_message to get the message associated with an error code.

Parameters

board

The board instance returned by the quanser.hardware.hil.open function.

channels

A vector of channel numbers. Channel numbers are zero-based.

Select a board type from the list for board-specific details: .

Outputs

voltages

A vector of analog voltages, as doubles. There must be one element for each channel.

err

A negative error code or zero on success.

Examples

% Reads analog channels 0, 3 and 5
volts = board.read_analog([0 3 5]);
