hil_set_encoder_counts

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 count values of the specified encoder channels.

Syntax

err = hil_set_encoder_counts(board, channels, counts)

Description

Sets the count values of the specified encoder channels so that subsequent reads from the same encoder channels will have the new count values (until the encoders are moved). This function is useful for resetting the encoders at the home position of the system being controlled.

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: .

counts

A vector specifying the count values. There must be one element for each channel in the channels vector.

Outputs

err

A negative error code or zero on success.

Examples

% Sets encoder channels 0 and 5 to 0 and channel 3 to 100
hil_set_encoder_counts(board, [0 3 5], [0 100 0]);
