Part Number: TDA2EVM5777

Hi,

I am using Infoadas. How can we implement a message queue so that it wecan transfer data from a userspace GUI (a QT GUI) to one of our usecase? How can we send data from user space GUI to usecase? How to know to which messageQ we need to send and How to know the Queue Id and the core?

Hi Ganesh,

the message queues has names. First you create MessageQ with MessageQ_create(String name, ...) function.
Then you use MessageQ_open(String name, ...) to open the queue on another (or the same) processor.

You can check documentation for MessageQ here:
processors.wiki.ti.com/.../MessageQ_Module
software-dl.ti.com/.../index.html
downloads.ti.com/.../_message_q_8h.html

You can look at "IPC Users Guide" here:
processors.wiki.ti.com/.../IPC_Users_Guide

There are also some IPC examples in "<VisionSDK_inst_dir>\ti_components\os_tools\ipc_3_43_03_05\examples".

Regards,
Yordan
