quanser.hardware.hil.set_encoder_counts

navigation bar

Sets the count values of the specified encoder channels.

Syntax

board.set_encoder_counts(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 instance returned by the quanser.hardware.hil.open function.

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
board.set_encoder_counts([0 3 5], [0 100 0]);
