What is BeadaPanel?

BeadaPanel is a versatile media display. It can playback images and videos in various common format. BeadaPanel comes with a 7" LCD display with a resolution of 800x480 and a 4-wire resistive touch panel. BeadaPanel has up to 16GB/32GB eMMC memory for media storage and playback. BeadaPanel supports USB 2.0 High Speed standard and WiFi communication. BeadaPanel consumes very low power and can be powered by a single Micro-USB cable. BeadaPanel comes with its own ABS bezel, which is easy to integrate into customer products.

In this application, BeadaPanel is used as a monitor/display for Raspberry Pi mini PC.

Applications

BeadaPanel for Raspberry Pi

In this application, BeadaPanel is used as a monitor/display for Raspberry Pi mini PC. Eenew.jpg

Supported Models and OS

Supported Model

Raspberry Pi A/B/B+/Zero/Zero W/2B/3B/3B+

OS Support

  • Raspbian
  • RetroPie
  • Ubuntu MATE
  • Ubuntu Core
  • CentOS
  • Kali Linux


First time setup

BeadaPanel will not work automatically when first time plugin to Raspberry Pi. Instead, A beadapanel deamon program should be running on Raspberry Pi to handle the data transmit between two USB peers. Below are procedures to setup this beadapanel deamon.

Pre-requirements
  • A Raspberry Pi mini PC
  • A BeadaPanel display kit
Procedures

1. Power on your Raspberry Pi mini PC
2. Connect BeadaPanel to Raspberry Pi by a Micro USB cable
3. BeadaPanel will be automaticaly recognized as a USB mass storage device by Raspberry Pi

pi@raspberrypi:~ $ lsblk
NAME        MAJ:MIN RM  SIZE RO TYPE MOUNTPOINT
sda           8:0    0  9.1G  0 disk
├─sda1        8:1    0 43.9M  0 part /media/pi/boot
└─sda2        8:2    0  4.9G  0 part /media/pi/rootfs
mmcblk0     179:0    0  7.4G  0 disk
├─mmcblk0p1 179:1    0 43.9M  0 part /boot
└─mmcblk0p2 179:2    0  7.4G  0 part /
pi@raspberrypi:~ $ ls /media/pi/boot/bpd
bpd

4. Locate and run beadapanel deamon in /media/pi/boot/bpd folder

pi@raspberrypi:~ $ sudo cp /media/pi/boot/bpd/bpd /usr/bin 
pi@raspberrypi:~ $ sudo chmod +x /usr/bin/bpd
pi@raspberrypi:~ $ sudo bpd
BeadaPanel Daemon Ver. 1.0

5. Run beadapanel deamon from booting

$ sudo nano /etc/rc.local -> add new line before "exit 0" with "/usr/bin/bpd &" without quote 
$ sudo reboot


Force Raspberry Pi display through HDMI

In order to let beadapanel deamon program successfully transmit HDMI video data to BeadaPanel, we have to force Raspberry Pi HDMI port work even if no HDMI monitor plugin. Further more, for best video performance purpose, we'd better to set Raspberry Pi HDMI port work under same resolution with BeadaPanel's native screen.

Procedures

1. To solve the problem, simply connect to your Raspberry Pi via SSH and modify with your favorite text editor (here we will use nano) the file /boot/config.txt.

2. Note that you will need administrator rights and therefore sudo command (with nano this will give for example sudo nano /boot/config.txt).

3. You should then find within this file the following two lines (if not, add them at the end):

#hdmi_force_hotplug=1
#hdmi_drive=2

4. To solve the problem you just have to uncomment (ie remove the sign # at the beginning) these lines and save the file (Ctrl + o, Enter, Ctrl + x with nano). Restart your Raspberry Pi and you're done!
