hil_set_encoder_filter_frequency

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.

Sets the filter frequencies of the specified encoder channels.

Syntax

err = hil_set_encoder_filter_frequency(board, channels, frequencies)

Description

Configures the filter frequencies of the specified encoder channels. Not all boards support configuration of the encoder filter frequencies. The driver for the board will round the given filter frequencies to the nearest achievable values.

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: .

frequencies

A vector specifying the filter frequencies. There must be one element for each channel in the channels vector.

Outputs

err

A negative error code or zero on success.

Examples

% Sets filter frequencies of encoder channels 0, 3 and 5 to 10 kHz, 1 MHz and 100 kHz respectively.
