Roomba Send IR
Sends the requested byte out of low side driver 1.
Library
MATLAB Command Line
Click to copy the following command line to the clipboard. Then paste it in the MATLAB Command Window:
qc_open_library('quarc_library/Devices/Third-Party/iRobot/Roomba/Interfacing')Description
The Roomba Send IR block sends the requested byte (0 to 255) out of low side driver 1 (pin 23 on the Cargo Bay Connector), using the format (see the iRobot Create Open Interface v.2 Manual document available from the iRobot website for detail information on infrared bytes) expected by iRobot Roomba's IR receiver. A preload resistor (suggested value: 100 ohms) in parallel with the IR LED and its resistor must be used in order turn it on.
This command is available in Safe, or Full operating mode of Roomba (see Roomba Modes block). Execution of this command does not change current Roomba operating mode.
Important Notes
Use System Timebase
block in Normal simulation.
Input Ports
rmb
A reference to the Roomba stream (see Roomba Initialize block).
ir
Specifies the infrared byte (0 to 255).
Output Ports
rmb
A reference to the Roomba stream, which is the same as input Roomba stream reference. It helps creating a daisy chain of Roomba blocks.
err
This signal returns a negative value in case of memory allocation error or data communication error through Roomba serial port.
Parameters and Dialog Box
Sample time
The sample time of the block. A sample time of 0 indicates that the block will be treated as a continuous time block. A positive sample time indicates that the block is a discrete time block with the given sample time. A sample time of -1 indicates that the block inherits its sample time.
