发表了主题帖：【Bit-Brick K1开源开发板】NAS体验

本帖最后由 TL-LED 于 2025-4-15 14:06 编辑体验Bianbu NAS系统一、简介 Bianbu NAS 是在 Bianbu 操作系统基础上精简并深度优化的一款专为 NAS 产品设计的系统。它集成了应用程序（如 openmediavault、docker 和常用软件）、框架、库、运行时环境、Linux 内核、引导加载程序（U-Boot）和监管程序接口（OpenSBI）等多种组件。该系统的目标是为客户提供 NAS 软件的参考设计，并支持驱动和应用程序的开发。二、下载固件下载地址：https://archive.spacemit.com/image/k1/version/bianbu/v2.1.1/ 三、烧写固件 3.1、选择镜像和U盘 3.2、烧录固件 3.3、烧录完成四、启动NAS 4.1、启动报错烧写上面最新版本固件，出现下面错误 4.2、降低版本，烧写V2.1版本固件下载地址：https://archive.spacemit.com/image/k1/version/bianbu/v2.1/ 4.3、登录系统 USB-TTL连接串口调试口串口登录，用户名：root 密码：bianbu 执行ifconfig查询IP地址 4.4、Openmediavault Web管理界面登录知道板卡IP地址后，在浏览器输入http://192.168.1.13 进入登录界面输入用户名：admin 密码：openmediavault，进入管理界面使用中出现一个问题，设备断电后，安装M2固态硬盘，再重新启动设备，输入用户名和密码进不去Openmediavault Web管理界面。重新烧写固件，正常进入。五、挂载硬盘 5.1、装好固态硬盘后，系统找到的硬盘。 5.2、挂载硬盘挂载完成六、共享文件夹 6.1、创建共享文件夹 6.2、保存更改 6.3、创建完成设置完成后，重启系统又进不去Openmediavault Web管理界面。重新烧写固件，继续操作。七、启动SMB和共享 7.1、启动SMB服务 7.2、启动SMB共享八、创建用户 8.1、创建用户 8.2、设置用户权限九、访问NAS 上面步骤创建完成后，访问NAS共享的文件夹在网络上找到了NAS的设备输入用户名和密码后，进入共享的文件夹

本帖最后由 TL-LED 于 2025-4-14 20:57 编辑在开发板上测试USB摄像头显示图像。一、查看USB设备连接USB摄像头，执行命令查看摄像头设备命令：spacemit-k1-x-deb1-board% lsusb 二、查看摄像头信息 2.1、安装v4l2-ctl工具命令：spacemit-k1-x-deb1-board% sudo apt install v4l-utils 2.2、查看连接的摄像头设备命令：spacemit-k1-x-deb1-board% v4l2-ctl --list-device 看到连接USB摄像头的设备三、查看视频 3.1、查看下上面坚持到的USB摄像头设备命令：spacemit-k1-x-deb1-board% ls /dev/video2* 3.2、cheese软件系统自带cheese软件，查看cheese软件 3.3、测试摄像头命令：spacemit-k1-x-deb1-board% cheese -d /dev/video20
发表了主题帖：【Bit-Brick K1开源开发板】VNC远程桌面

本帖最后由 TL-LED 于 2025-4-14 18:40 编辑测试远程访问系统桌面。一、安装vncserver软件执行命令： spacemit-k1-x-deb1-board% sudo apt-get update spacemit-k1-x-deb1-board% sudo apt install tightvncserver spacemit-k1-x-deb1-board% sudo apt-get install gnome-panel 二、修改配置文件命令：spacemit-k1-x-deb1-board% vi .vnc/xstartup 内容替换成下面内容， #!/bin/sh unset SESSION_MANAGER unset DBUS_SESSION_BUS_ADDRESS export XKL_XMODMAP_DISABLE=1 export XDG_CURRENT_DESKTOP="GNOME-Flashback:GNOME" export XDG_MENU_PREFIX="gnome-flashback-" [ -x /etc/vnc/xstartup ] && exec /etc/vnc/xstartup [ -r $HOME/.Xresources ] && xrdb $HOME/.Xresources xsetroot -solid grey vncconfig -iconic & gnome-terminal & #nautilus & gnome-session --session=gnome-flashback-metacity --disable-acceleration-check & 二、启动vncserver 2.1、创建登录密码命令：spacemit-k1-x-deb1-board% vncpasswd 2.2、启动vnserver 命令： spacemit-k1-x-deb1-board% vncserver -kill :1 spacemit-k1-x-deb1-board% vncserver :1 或命令：spacemit-k1-x-deb1-board% tightvncserver 三、远程登录输入IP地址和端口号输入创建的登录密码登陆后，进入桌面，和HDMI界面有点区别，可能和配置的有关

回复了主题帖： NUCLEO-C092RC开发板测评（四）——基于SPI驱动1.8寸tft屏幕

FuShenxiao 发表于 2025-4-12 14:22 这个视频展示的代码是在STM32CubeIDE里面写的，后来我换成在keil里面写，屏幕刷新速度快了不少，但依然 ... IO口输出速度改高速，LCD刷新速度会不会有改变

本帖最后由 TL-LED 于 2025-4-11 20:14 编辑测试使用板卡的SPI方式驱动LCD显示屏。一、硬件电路部分 1.1、硬件端口测试使用板卡上的SPI2，驱动单色LCD显示屏。驱动显示屏使用下面的引脚。 1.2、显示屏驱动时序图二、配置SPI 在STM32CubeMX软件中配置SPI2 配置SPI2为半双工通信，CLK上升沿采样，时钟频率12MHz 配置SPI2对应的引脚三、代码

本帖最后由 TL-LED 于 2025-4-9 18:43 编辑按照教程来学习下安装ROS2。一、系统设置设置地区 1.1、检查UTF-8 命令：locale 1.2、设置命令：sudo apt update && sudo apt install locales 命令：sudo locale-gen en_US en_US.UTF-8 命令：sudo update-locale LC_ALL=en_US.UTF-8 LANG=en_US.UTF-8 命令：export LANG=en_US.UTF-8 1.3、验证设置命令：locale 二、启动所需要的软件库命令1：sudo apt install software-properties-common 命令2：sudo add-apt-repository universe 三、安装依赖项执行以下命令： sudo apt update && sudo apt upgrade && sudo apt install -y \ build-essential \ cmake \ git \ apt-utils \ ca-certificates \ conntrack \ curl \ dh-python \ dhcpcd5 \ ebtables \ ethtool \ git-lfs \ gnupg2 \ ifupdown \ iptables \ iproute2 \ iputils-ping \ libasio-dev \ libbullet-dev \ libconsole-bridge-dev \ libtinyxml2-dev \ libeigen3-dev \ lsb-release \ net-tools \ openssh-client \ python3-dev \ python3-distlib \ python3-empy \ python3-lark \ python3-notify2 \ python3-numpy \ python3-pip \ python3-pytest-cov \ python3-setuptools \ python3-yaml \ samba \ socat \ systemd \ vim \ wget 执行完成有一些依赖项在没有ROS 2软件库的情况下是无法获得的。我们使用pip来安装：执行命令： sudo pip install vcstool \ rosdep \ catkin-pkg-modules \ rosdistro-modules \ colcon-common-extensions 执行命令后，会有提示报错创建虚拟环境，使用pip包管理工具安装软件包。执行命令： sudo apt install python3-scipy sudo apt install python3-virtualenv 创建虚拟环境配置文件夹执行命令：virtualenv myenv 进入虚拟环境执行命令：source ~/ros2_venv/bin/activate 继续使用pip获取软件库安装过程报错添加/etc/apt/sources.list.d/ubuntu.list文件 deb http://ports.ubuntu.com/ubuntu-ports/ mantic main restricted universe multiverse # deb-src https://mirrors.tuna.tsinghua.edu.cn/ubuntu-ports/ mantic main restricted universe multiverse deb http://ports.ubuntu.com/ubuntu-ports/ mantic-updates main restricted universe multiverse # deb-src https://mirrors.tuna.tsinghua.edu.cn/ubuntu-ports/ mantic-updates main restricted universe multiverse deb http://ports.ubuntu.com/ubuntu-ports/ mantic-backports main restricted universe multiverse # deb-src https://mirrors.tuna.tsinghua.edu.cn/ubuntu-ports/ mantic-backports main restricted universe multiverse # 以下安全更新软件源包含了官方源与镜像站配置，如有需要可自行修改注释切换 deb http://ports.ubuntu.com/ubuntu-ports/ mantic-security main restricted universe multiverse # deb-src http://ports.ubuntu.com/ubuntu-ports/ mantic-security main restricted universe multiverse # 预发布软件源，不建议启用 deb http://ports.ubuntu.com/ubuntu-ports/ mantic-proposed main restricted universe multiverse # # deb-src https://mirrors.tuna.tsinghua.edu.cn/ubuntu-ports/ mantic-propo 执行命令： sudo apt-get install python3-catkin-pkg sudo apt-get install python3-rosdistro sudo apt install vcstool 四、构建ROS2 执行命令： mkdir -p ~/ros2/ros2_iron/src cd ~/ros2/ros2_iron vcs import --input https://raw.githubusercontent.com/ros2/ros2/iron/ros2.repos src 下载后的文件由于报错问题较多，安装没有成功。

测试开发板的扩展IO口的输出，驱动LED灯。一、开发板的扩展GPIO口 1.1、GPIO接口引脚号 1.2、GPIO引脚定义二、安装python包使用apt安装python包执行命令：sudo apt install python3-scipy 三、安装 gpiozero库执行命令：sudo apt install python3-gpiozero 列出引脚执行命令：sudo pinout 列出的引脚只有前26pin，后面没有列出，下面就在前26pin上进行测试。四、测试代码测试使用GPIIO[51]号引脚，连接到LED灯。创建led.py from gpiozero.pins.lgpio import LGPIOFactory from gpiozero import Device Device.pin_factory = LGPIOFactory(chip=0) from gpiozero import LED from gpiozero import PWMLED from signal import pause from time import sleep led = PWMLED(51); try: while True: led.pulse(); pause(); except KeyboardInterrupt: print("Exiting") led.close() 五、运行结果运行程序后，LED点亮状态 [localvideo]df4693f137042f4ceb4bbc609013c4c4[/localvideo]
发表了主题帖：【Bit-Brick K1开源开发板】烧写Bianbu系统

本帖最后由 TL-LED 于 2025-4-8 17:49 编辑按照教程安装Bianbu操作系统到SD卡。一、硬件准备 1.1、电源适配器和TYPEC USB线 K1单板电脑不带一些外设的情况下，整机的功耗在2W左右，建议使用10W或功率更大的适配器。 1.2、TF卡 K1单板电脑没有集成EMMC FLASH，所以我们需要采用外部存储来作为固件存储的介质，推荐Micro SD卡至少是32GB以上，CLASS10的高速卡。 1.3、外设显示器,HDMI，鼠标和键盘。若使用桌面系统，连接这些外设实现桌面操作。 1.4、串口和网络板卡上没有可以直接连接电脑的串口，支持TTL电平的串口，需要USB转TTL模块与电脑串口通信。板卡上没有无线网卡，需要网络通信需要连接网线到板卡上的网口。二、安装系统 2.1、下载Bianbu操作系统 Bianbu 系统是BIT-BRICK K1的默认操作系统，它是一个基于Ubuntu社区源码编译的针对RISC-V深度优化的一个操作系统。系统下载地址：https://archive.spacemit.com/image/k1/version/bianbu/v2.1/bianbu-24.04-desktop-k1-v2.1-release-20250124144655.img.zip 下载后解压得到.img固件文件 2.2、安装系统使用balenaEtcher软件安装系统到TF卡 balenaEtcher软件下载地址：https://etcher.balena.io/#download-etcher 下载对应系统的安装包，这里我使用Windows系统下的安装包。打开balenaEtcher软件，选择系统固件和TF卡，烧写系统烧写完成三、硬件连接连接鼠标、键盘和显示器四、运行系统系统安装完成后，TF卡插入板卡上，连接鼠标、键盘、HDMI显示器和网络，上电等待进入系统。进入系统后按照提示设置后，进入桌面。

jobszheng5 发表于 2025-4-1 16:02 C0系列没有PLL时钟，是不是更适合使用HSI的48MHz时钟啊我觉得还是根据应用吧，要求时钟精度高的选外部，其他选内部就行。

本帖最后由 TL-LED 于 2025-4-1 12:37 编辑一、官网资料 1.1、开发板官网地址：https://www.st.com/en/evaluation-tools/nucleo-c092rc.html 1.2、下载STM32CubeMX软件创建项目使用官网的STM32Cube软件软件下载地址：https://www.st.com/en/development-tools/stm32cubemx.html 1.3、下载pack 地址：https://www.keil.arm.com/packs/stm32c0xx_dfp-keil/overview/ 二、创建项目 2.1、选择芯片型号 2.2、使能外部晶振，选择时钟和设置晶振频率 2.3、使能调试口默认调试口试禁止的，需要打开调试口，否则，创建项目完成后，烧写一次程序就禁用调试口，下次就写不进程序。 2.4、配置GPIO口测试板子上的LED灯，使用的端口是PA5和PC9 2.5、生成工程填写工程名称、路径和编译工具三、代码打开创建的工程修改main.c，添加代码四、运行编译后，下载程序到开发板，复位后，LED闪烁。 [localvideo]fb980d81dd819b399c679eb686552d0f[/localvideo]
