hil_write_analog

Deprecated

The HIL API MATLAB functions have been deprecated in favour of the new quanser.hardware.hil class, which has support for code generation for Quanser targets. Hence, with the new hil class it is possible to run MATLAB scripts in real-time on Quanser targets, while making use of the Quanser hardware.

Writes to the specified analog channels.

Syntax

err = hil_write_analog(board, channels, voltages)

Description

Writes the given voltages to the specified analog channels immediately.

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 handle returned by hil_open.

channels

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

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

voltages

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

Outputs

err

A negative error code or zero on success.

Examples

% Writes 0.5V to analog channel 0, 1.2V to channel 3 and -0.5V to channel 5
hil_write_analog(board, [0 3 5], [0.5 1.2 -0.5]);
