hil_write_digital
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. |
Writes to the specified digital channels.
err = hil_write_digital(board, channels, values)
Writes to the specified digital channels immediately. It takes a vector of logical values where true (1) represents a high digital output, and false (0) represents a low digital output.
Many cards allow the digital I/O lines to be programmed as inputs or outputs. The digital I/O lines are configured as inputs or outputs using the hil_set_digital_directions function. All the channels which will be used as digital outputs must be configured as outputs using this function. Failure to configure the digital I/O may result in the hil_write_digital function failing to write those outputs.
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.
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: .
values
A vector of logical values. A value of true (1) represents a high digital output and a value of false (0) represents a low digital output. There must be one element for each channel.
err
A negative error code or zero on success.
% Writes 0 to digital channel 0, 1 to channel 3 and 0 to channel 5
hil_write_digital(board, [0 3 5], [0 1 0]);
