hil_read_encoder

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 encoder channels.

Syntax

[counts, err] = hil_read_encoder(board, channels)
    

Description

Reads the specified encoder channels immediately. It returns vector of signed integer values representing the encoder counts.

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

counts

A vector of encoder counts, as int32s. There is one element for each channel.

err

A negative error code or zero on success.

Examples

% Reads encoder channels 0, 3 and 5
counts = hil_read_encoder(board, [0 3 5]);
