quanser.hardware.hil.write_analog

Writes to the specified analog channels.

Syntax

err = board.write_analog(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 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: .

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
board.write_analog([0 3 5], [0.5 1.2 -0.5]);
