C6 Integra - C6A816x EVM - Building Qt for ARM and displaying Qt applications on the LCD display.

Aravinda P N

Hello,

We are using the C6A816x EVM (ARM+DSP) for our project. The EVM comes along with a LCD display module. 

We also have installed the EZSDK. The EZSDK has a number of example Qt applications(eg: signal_analyser).

By default, when the EVM is powered up and booted from the SD card, the "matrix GUI " application is launched and we are able to see the various icons(signal_analyser,etc) on the LCD display. Upon clicking these icons, the corresponding Qt application is executed and output is displayed on the LCD.

We need help regarding the following:

1. We need to create our own Qt application and run this on the EVM and display this output on the LCD. We understand that this requires that we build the Qt  application for the ARM core. How do we do this? Where are the available Qt libraries for the ARM?Are these a part of the EZSDK or  Do we need to download embedded Qt for Linux?

Could you please provide us the detailed steps for building and running a very simple(own) Qt application on the C6 Integra EVM?

2. Going forward, we also plan to use the "qwt library"  for plotting graphs. We have also downloaded and installed the package qwt_5_2_0.  We are able to run the example applications provided on the Host Linux system. However, how do we build these for the ARM core? Could you please provide us information on where we would find the qwt libraries and other dependent libraries required to build such applications for the ARM core so that we can execute them on the C6 Integra EVM?

Thanks in advance.

Regards,

Aravinda

    hi aravinda,

    I may not be able to answer your specific doubts, but i can point to some links which can you help you in building simple qt applications for your EVM. please refer to the 4th LAB Developing a GUI using Qtopia and QT Creator  for TI814x in the following link

    http://processors.wiki.ti.com/index.php/TI816x_One-day_Workshop

    the steps for 816x are same as that of 814x.

    you need to download the qt creator 2.4.1 or newer from nokia qt website. There are ample amout of tutorials available all over the web for qt development on ARM platforms. 

    Also i am attaching a beginners guide for qt application.

    hope this helps

    with best regards
