hil_read_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.

Reads the specified analog channels immediately, returning raw integer analog codes instead of voltages.

Syntax

[codes, err] = hil_read_analog_codes(board, channels)

Description

Reads the specified analog channels. However, instead of returning voltages, the raw integer analog codes are returned. This function is useful for fixed-point computations or for teaching A/D 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: .

Outputs

codes

A vector of raw analog codes, as int32s. There is one element for each channel.

err

A negative error code or zero on success.

Examples

% Reads raw analog codes of analog channels 0, 3 and 5
codes = hil_read_analog_codes(board, [0 3 5]);
