quanser.hardware.hil.set_encoder_quadrature_mode

Sets the quadrature modes of the specified encoder channels.

Syntax

err = board.set_encoder_quadrature_mode(channels, modes)
    

Description

Configures the quadrature modes of the specified encoder channels. Valid modes are 0, 1, 2 or 4, for no quadrature, 1X, 2X or 4X quadrature respectively. In no quadrature mode the A and B channels are typically treated as count and direction.

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: .

modes

A vector specifying the quadrature modes. There must be one element for each channel in the channels vector. Each element must have a value of 0, 1, 2 or 4.

Outputs

err

A negative error code or zero on success.

Examples

% Sets encoder channels 0, 3 and 5 to none, 4X and 2X quadrature respectively.
board.set_encoder_quadrature_mode([0 3 5], [0 4 2]);
