hil_write_analog_codes

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. The raw integer analog codes are used instead of voltages.

Syntax

err = hil_write_analog_codes(board, channels, codes)

Description

Writes the given raw analog codes to the specified analog channels immediately. This function does not use voltages. It is useful for fixed-point computations and for teaching D/A concepts.

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: .

codes

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

Outputs

err

A negative error code or zero on success.

Examples

% Writes the DAC code 0 to analog channel 0, 1024 to channel 3 and 4095 to channel 5
hil_write_analog_codes(board, [0 3 5], [0 1024 4095]);
