LED Screen Display Control Instructions

• The configuration files are located in the /usr/share/openvfd directory of the Armbian/OpenWrt system. The command file for the Armbian system is at /usr/sbin/armbian-openvfd, and the command file for the OpenWrt system is at /usr/sbin/openwrt-openvfd. If they are not currently in the system, they can be manually uploaded, and file execution permissions can be assigned: chmod +x /usr/share/openvfd/vfdservice /usr/sbin/*-openvfd.

• Upgrade the system kernel to the latest version. The Armbian system uses the armbian-update command for upgrades. The OpenWrt system upgrades using System Menu → Amlogic Service → Online Download Update.

• Currently, x96max.conf, x96maxplus.conf, h96max-x3.conf, hk1-x3.conf, hk1box.conf, tx3.conf, x96air.conf, x88pro-x3.conf and other devices have been tested. Configurations for other devices can be modified by checking: arthur-liberman/vfd-configurations and LibreELEC/linux_openvfd. The second field value in the corresponding content in the configuration files from these two websites needs to be reduced by 1. For example:

vfd_gpio_clk='0,69,0'
vfd_gpio_dat='0,70,0'

Modify to:

vfd_gpio_clk='0,68,0'
vfd_gpio_dat='0,69,0'

• Taking the configuration of x96maxplus as an example: If the order of the displayed time text is incorrect, you can adjust the order of numbers in vfd_chars='4,0,1,2,3' to vfd_chars='1,2,3,4,0' for testing. If the time is displayed upside down, you can adjust the first value 0x02 in vfd_display_type='0x02,0x00,0x01,0x00' to 0x01 for testing. The content displayed can be adjusted according to the specific situation of your device in functions='usb apps setup sd hdmi cvbs'.

• Rename the configuration file to diy.conf and upload it to the /usr/share/openvfd/conf directory, then enter the command armbian-openvfd 99 for testing.

• The command armbian-openvfd 0 can disable the LED display and clear the system process. Before each new configuration test, please first execute this disable command, and then execute armbian-openvfd 99 to test the modified configuration.

• After the screen display is normal, you can add it to the boot autostart task, change the 15 in the following command to your box number:

# Execute the following command in the terminal to enable the openvfd service
sed -i 's|^#*openvfd_enable=.*|openvfd_enable="yes"|g' /etc/custom_service/start_service.sh
sed -i 's|^#*openvfd_boxid=.*|openvfd_boxid="15"|g' /etc/custom_service/start_service.sh

• Everyone is welcome to test and share their device's configuration file (diy.conf) to benefit more people.

LED 屏显示控制说明

• 配置文件放在 Armbian/OpenWrt 系统的 /usr/share/openvfd 目录下，Armbian 系统的命令文件位于 /usr/sbin/armbian-openvfd，OpenWrt 系统的命令文件位于 /usr/sbin/openwrt-openvfd。如果当前系统中没有的可以手动上传，并赋予文件执行权限：chmod +x /usr/share/openvfd/vfdservice /usr/sbin/*-openvfd

• 将系统的内核升级到最新版本。Armbian 系统使用 armbian-update 命令升级。OpenWrt 系统使用 系统菜单 → 晶晨宝盒 → 在线下载更新 功能升级。

• 目前有 x96max.conf、x96maxplus.conf、h96max-x3.conf、hk1-x3.conf、hk1box.conf、tx3.conf、x96air.conf 和 x88pro-x3.conf 等设备经过测试，其他设备的配置可以查看：arthur-liberman/vfd-configurations 和 LibreELEC/linux_openvfd 进行修改，需要把这两个网站中配置文件里对应内容中进行调整，把第二个字段的值减 1 后使用，如：

vfd_gpio_clk='0,69,0'
vfd_gpio_dat='0,70,0'

修改为：

vfd_gpio_clk='0,68,0'
vfd_gpio_dat='0,69,0'

• 以 x96maxplus 的配置为例：如果显示的时间文字顺序不正确，可以调整 vfd_chars='4,0,1,2,3' 的数字顺序为 vfd_chars='1,2,3,4,0' 等进行测试。如果时间是翻转显示，可以调整 vfd_display_type='0x02,0x00,0x01,0x00' 中的 第一个值 0x02 为 0x01 等进行测试。显示的内容可根据自己的设备支持的具体情况调整 functions='usb apps setup sd hdmi cvbs' 中的值。

• 将配置文件命名为 diy.conf 并上传至 /usr/share/openvfd/conf 目录下，输入命令 armbian-openvfd 99 进行测试。

• 通过命令 armbian-openvfd 0 可以禁用 LED 显示并清除系统进程，在每次测试新的配置前，请先执行此禁用命令，再执行 armbian-openvfd 99 进行更改后的配置测试。

• 屏幕显示正常后，可以添加至开机自启动任务，下面命令中的 15 改为你的 盒子编号 ：

# 在终端执行以下命令启用 openvfd 服务
sed -i 's|^#*openvfd_enable=.*|openvfd_enable="yes"|g' /etc/custom_service/start_service.sh
sed -i 's|^#*openvfd_boxid=.*|openvfd_boxid="15"|g' /etc/custom_service/start_service.sh

• 欢迎大家测试后分享自己设备的配置文件（ diy.conf ），让更多人受益。
