上海做网站收费2024年3月份病毒会爆发吗
一、前言
本编文章记录在使用嵌入式系统中的一些功能测试demo程序，大部分都是AI写的，哈哈哈，确实很有帮助，但是得根据自身设备实际情况和知道如何问AI，才能得出你想要的结果，本文就记录一些ubuntu/麒麟系统实际使用过程中测试程序。
目录
1.串口测试程序
2.CAN测试程序
3.背光测试程序（弥补系统pwm匹配异常）
4.电量获取程序（弥补底系统版本不支持电池管理）
5.GPIO测试程序控制状态led灯
6.时间测试程序
7.redis通信测试程序
8.温度、CPU主频测试程序
9.msata挂载稳定性测试程序
二、环境
RK3588（linux5.10.66+debian/ubuntu/麒麟是桌面文件系统）
调试笔记本window10，安装常用工具winscp，xshell，finalshell，secureRTP等等
VMware17+Ubuntu20.04源码开发环境（这里就依赖于各个硬件平台的厂家提供资料了）
QT5.7
三、正文
程序都是QT环境开发的程序，程序内容放的都是核心代码，相关头文件简单补充，或者直接参考核心代码继续询问AI即可，大部分AI都是可以解决的
统一说明main.cpp引用了全局函数MySleep（），common.h也都是头文件
main.cpp
//延时usetime：非阻塞时间 waittime：阻塞时间
void MySleep(uint usetime,ulong waittime)
{QCoreApplication::processEvents(QEventLoop::AllEvents, usetime);//进入此函数内给之前数据usetime毫秒时间处理，处理完立马退出执行之后，超时立马退出QThread::msleep(waittime);//阻塞延时waittime毫秒

前两路2是调用系统自带的CAN，用socketcan，可以参考我A40i帖子中的一个CAN文章
后两路CAN是其他厂家的一个USB转CAN模块，需要匹配相关的驱动，与厂家要驱动文件，引用，可能需要重新根据系统编译一下libusb-1.0.so，才能在交叉编译环境中编译通过
3.背光测试程序（弥补系统pwm匹配异常）
麒麟系统连接edp或mipi屏幕时，会出现pwm不受控现象，麒麟系统与硬件没有完成适配兼容，因为在系统设置中调节亮度不好使
下面通过第三方软件或其他方法尝试解决此问题
1第三方软件方式
未找到合适工具，最终通过自己写程序修改亮度
2自写脚本定时设置亮度方式。
命令参考手册的亮度设置章节
ls /sys/class/backlight
cat /sys/class/backlight/backlight-edp1/brightness
echo 0 > /sys/class/backlight/backlight-edp1/brightness
echo 125 > /sys/class/backlight/backlight-edp1/brightness
echo 255 > /sys/class/backlight/backlight-edp1/brightness
写了一个test_backlight测试程序，当检测到亮度为0时自动设置亮度信息为上次配置的
缺点是会出现一下黑屏，闪一下
最佳解决方式是后期更换稳定系统
后续测试高版本的linux源码尝试

4.电量获取程序（弥补底系统版本不支持电池管理）
麒麟系统V10 2303默认不支持电源管理功能，没有电池图标右下角的显示
使用xx电源模块在国防版麒麟系统可以显示电量信息，但是国防版系统镜像不好用缺图标
最终还是使用2303系统，需要自己通过软件获取电量信息
等以后有了2403系统，就没有这个问题了
方法：
upower -e
upower -i /org/freedesktop/UPower/devices/ups_hiddev0
后续写了一个demo程序 test_power，用于监测电源模块电量信息，等以后写程序可以集成在程序之中
