Embedded Target for Texas Instruments C6000 DSPs

To Rtdx

Add a named RTDX output channel to Simulink models

Library

rtdxBlocks in Embedded Target for TI C6000 DSP for TI DSP

Description

When your Simulink model with this block is in place, Real-Time Workshop code generation inserts the C commands to create an RTDX output channel on the target. The inserted code opens and enables the channel with the name you specify in Channel name. You can open, close, disable, and enable the channel from the host side afterwords, overriding the target side status.

In the generated code from models with this block, you see a command like

• RTDX_enableOutput(&channelname)
  

where channelname is the name you enter in Channel name.

In simulations this block does not perform any operations. To Rtdx blocks work only in code generation and when your model runs on your target.

Using RTDX in your model involves:

• Adding one or more RTDX blocks to your model to prepare your target
• Downloading and running your model on your target
• Enabling the RTDX channels from MATLAB
• Using the readmsg and writemsg functions in MATLAB to send and retrieve data from the target over RTDX

To see more details about using RTDX in your model, refer to
Tutorial 3-2--Using Links for RTDX.

Dialog Box

Channel name

Defines the name of the output channel on the target DSP. Recall that output channels refer to transferring data from the target to the host (output from the target). To use this RTDX channel, you enable and open the channel with the name, and send data from the target to the host across this channel. Specify any name as long as it meets C syntax requirements for length and character content.
