Qt应用开发--国产工业开发板全志T113-i的部署教程

news 2026/2/8 22:59:53

Qt在工业上的使用场景包括工业自动化、嵌入式系统、汽车行业、航空航天、医疗设备、制造业和物联网应用。Qt被用来开发工业设备的用户界面、控制系统、嵌入式应用和其他工业应用，因其跨平台性和丰富的功能而备受青睐。

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-A7@1.2GHz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：

rice@rice:~$ mkdir t113             //创建t113工作目录，然后将压缩包拷贝到此目录
rice@rice:~$ cd t113
....rice@rice:~/t113$ tar -zxvf SDK-T113-i_v1.0.tar.gz
rice@rice:~/t113$ cd T113-i_v1.0/
rice@rice:~/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：

rice@rice:~/t113/T113-i_v1.0$ ./install_tools.sh
[sudo] password for rice:

解压Buildroot dl–dl.tar.gz，其为 Buildroot dl 目录压缩包，用于存放从官网下载的开源软件包：

rice@rice:~/t113$ tar -xvf dl.tar.gz -C ~/t113/buildroot/buildroot-201902/

构建Qt固件

在编译固件前，先清理一下SDK的编译和配置生成文件：

rice@rice:~/t113/T113-i_v1.0$ ./build.sh distclean

配置linux内核，处理器型号，显示方式，编译器等信息

rice@rice:~/t113/T113-i_v1.0$ ./build.sh config

Choice [gnueabi]: 0

设置编译的环境变量：

rice@rice:~/t113/T113-i_v1.0$ source ./build/envsetup.sh

我们采用一键编译 SPL、U-Boot、Linux 内核和 buildroot文件系统。

rice@rice:~/t113/T113-i_v1.0$ ./build.sh

编译Qt库，使其开发板固件支持Qt应用运行环境：

rice@rice:~/t113/T113-i_v1.0$ ./build.sh qt
ACTION List: mkqt;========
Execute command: mkqt

Thread model: posix.....

打包系统镜像文件，执行之后，可以看到生成的固件文件，它默认生成两个版本的固件，分别是：nand固件和SD卡固件，我们是采用SD卡启动，所以使用SD卡固件。

rice@rice:~/t113/T113-i_v1.0$ ./build.sh pack

运行环境验证

下载运行实例

将编译打包后的固件(t113_i_linux_tlt113-evm-nand-sdboot_uart0.img)放到windows上，通过工具PhoenixCard.exe烧录到SD卡上。将SD卡插到读卡器上，然后插进电脑：

创龙科技提供了qt的demo，我们将led_control的实例拷贝到板子上：

rice@rice:~/t113/qt-demos/led_control/bin$ scp led_control root@ip:~/

创龙T113-i上运行实例

关闭默认的Qt运行程序，设置qt的环境变量

root@T113-Tronlong:~# killall Launcher
root@T113-Tronlong:~# source /etc/qtenv.sh 
add /dev/input/event1 to Qt Application.
find qt5 installed done

运行实例验证Qt功能，运行效果如图：

root@T113-Tronlong:~# ./led_control

开发Qt应用

作者开发了一个快速验证硬件功能的，主要功能包含：

板载LED灯控制，代码实现：

static QString ledPath = "/sys/class/leds/user-led0";void rice::ledInit()
{setLedStatus(0);ui->ledPushButton->setText("LED OFF");ui->ledPushButton->setStyleSheet("border-width:1px;""border-style:solid; ""border-color:white;""background-color:rgba(88, 88, 88, 200)");
}void rice::ledDeinit()
{}bool rice::setLedStatus(int status)
{QString cmd = "echo " + QString::number(status) + " > " + ledPath + "/brightness";if (system(cmd.toStdString().c_str()) == -1) {printf("set led status failed!\n");return false;}return true;
}int rice::getLedStatus(void)
{QString cmd = "cat " + ledPath + "/brightness";FILE *fp = popen(cmd.toStdString().c_str(), "r");if (fp == nullptr) {return -1;}char led_status[32];if (fgets(led_status, sizeof(led_status), fp) == nullptr) {printf("fgets error: %s\n", cmd.toStdString().c_str());pclose(fp);return -1;}pclose(fp);return atoi(led_status);
}void rice::on_ledPushButton_clicked()
{int ledStatus = getLedStatus();if (ledStatus == 0) {setLedStatus(1);ui->ledPushButton->setText("LED ON");ui->ledPushButton->setStyleSheet("border-width:1px;""border-style:solid; ""border-color:white;""background-color:rgba(00, 205, 00, 255)");}else {setLedStatus(0);ui->ledPushButton->setText("LED OFF");ui->ledPushButton->setStyleSheet("border-width:1px;""border-style:solid; ""border-color:white;""background-color:rgba(88, 88, 88, 200)");}
}

板载按键检测，代码实现：

void rice::keyInit()
{keyFd = open(keyPath.toUtf8().data(), O_RDONLY);if(keyFd == -1){printf("Can not open file(%s)", keyPath.toUtf8().data());return;}ui->keyTextEdit->append("Key Monitor!\n");ui->keyTextEdit->append("Key user0 pressed!");keyNotify = new QSocketNotifier(this->keyFd, QSocketNotifier::Read, this);connect(this->keyNotify, SIGNAL(activated(int)), this, SLOT(keyHandler()));
}void rice::keyDeinit()
{}void rice::keyHandler()
{struct input_event buf;if(read(keyFd, &buf, sizeof(struct input_event)) > 0){if(buf.code == KEY_PROG1 && buf.value == 1){ui->keyTextEdit->append("Key user0 pressed!");}}
}

RTC时钟获取并显示，代码实现：

void rice::dateInit()
{struct rtc_time rtc_tm_temp;dateFd = open(datePath.toUtf8().data(), O_RDONLY);if(dateFd == -1){printf("Can not open file(%s)", keyPath.toUtf8().data());return;}if(ioctl(dateFd, RTC_RD_TIME, &rtc_tm_temp) < 0){printf("Get date failed");return;}ui->yearLineEdit->setText(QString::number(rtc_tm_temp.tm_year + 1900));ui->monthLineEdit->setText(QString::number(rtc_tm_temp.tm_mon + 1));ui->dayLineEdit->setText(QString::number(rtc_tm_temp.tm_mday));
}void rice::dateDeint()
{}

网络调试助手，代码实现：

void rice::netInit()
{server = new QTcpServer();socket = new QTcpSocket();
}void rice::netDeint()
{}void rice::netNewClientConnect()
{socket = server->nextPendingConnection();connect(socket, &QTcpSocket::readyRead, this, &rice::netNewRcve);
}void rice::on_netPushButton_clicked()
{int port = ui->portLineEdit->text().toInt();if(ui->netPushButton->text() == tr("Open")){if(ui->typeComboBox->currentText() == tr("Server")){connect(server, &QTcpServer::newConnection, this, &rice::netNewClientConnect);if(!server->listen(QHostAddress::Any, port)){printf("Listen failed\n");return;}}else if(ui->typeComboBox->currentText() == tr("Client")){QString ip = ui->ipComboBox->currentText();socket->abort();socket->connectToHost(ip, port);if(!socket->waitForConnected(3000)){printf("Connect server failed");return;}connect(socket, &QTcpSocket::readyRead, this, &rice::netNewRcve);}ui->netPushButton->setText("Close");}else if(ui->netPushButton->text() == tr("Close")){if(ui->typeComboBox->currentText() == tr("Server")){socket->abort();server->close();}else if(ui->typeComboBox->currentText() == tr("Client")){socket->disconnectFromHost();}ui->netPushButton->setText("Open");}
}void rice::on_sendPushButton_clicked()
{if(socket->isOpen()){socket->write(ui->sendLineEdit->text().toUtf8().data());}
}void rice::netNewRcve()
{ui->recvTextEdit->append(socket->readAll());
}void rice::on_typeComboBox_currentIndexChanged(const QString &arg1)
{if(arg1 == tr("Server")){ui->ipComboBox->setEditable(false);}else{ui->ipComboBox->setEditable(true);}
}
