Qt能够为工业领域带来什么好处 - Qt提供了强大的图形引擎使开发人员能够创建具有吸引力和高性能的用户界面 - Qt允许开发人员根据具体需求定制用户界面和功能。这对于满足不同行业和项目的独特需求至关重要使工业应用能够实现个性化的解决方案 - Qt提供了丰富的库和工具涵盖了各种应用程序开发需求包括图形、网络通信、多媒体处理、数据存储等。这简化了工业应用程序的开发流程 - Qt可以轻松与各种硬件设备和通信协议集成这对于工业自动化和控制系统来说非常重要因为它们需要与各种传感器、执行器和其他工业设备进行通信
创龙科技基于全志双核Cortex-A71.2GHz处理器T113-i精心设计的全国产工业开发板它提供了Qt的运行环境可以让我们快速的部署工业领域的用户交互界面控制系统等。
接下来我们来聊聊如何在创龙科技T113-i工业开发板上部署Qt应用。
开发板Qt运行环境
开发板SDK准备
创龙科技的资料中提供了开发板的SDK-T113-i_v1.0.tar.gz需要解压ubuntu中解压出来
ricerice:~$ mkdir t113 //创建t113工作目录然后将压缩包拷贝到此目录
ricerice:~$ cd t113
....ricerice:~/t113$ tar -zxvf SDK-T113-i_v1.0.tar.gz
ricerice:~/t113$ cd T113-i_v1.0/
ricerice:~/t113/T113-i_v1.0$ ls
brandy buildroot device install_tools.sh out rtos-dsp tools
build build.sh kernel platform test安装依赖软件创龙科技提供了安装脚本install_tools.sh我们执行该脚本即可完成依赖工具的安装
