Introduction

As computing terminal expanded gradually from the desktop to the portable handheld device, we have witnessed the rapid development of smart phones. The complex operating system also gradually get rid of the bloated body to be ported into MiniPC from PC including RaspberryPi, Cubieboard, the rounter embeded with OpenWrt, etc. Those become compact and easy to carry embedded platform with majority has Ghz level of the CPU.

Like MiniPC, with a compact system but containing considerable computing resources, becomes the computing solutions the various enthusiasts and many open source hardware vendors have been dreaming of for some time. However, some interactions like debugging or displaying for MiniPC still need those bulky HDMI monitor or even TV.

In order to allow the device having same portability and saving power, RoboPeak is proud to release RPUSBDisp, the portable USB monitor with touch screen. It is designed specifically for MiniPC with same size of business card, and just requires a USB cable to make it work without additional power supply.

Features

Extensive Device Support

You could leverage it as a display to present most of embedded development board on the current market (such as RaspberryPi, Cubieboard, etc.). Benefit from USB interface that provides opportunity for those devices that cannot connect with monitor for display in the past like Router.

Usage

Please download the document User Manual for specific Usage.

As a newly launched product, the core driver of RPUSBDisp has not yet become part of the firmware produced by MiniPC manufactures by default. So, to make RPUSBDisp to work, you need to install RPUSBDisp drivers.

Quick Start: Using Prebuilt ROM Image

For common MiniPC, you simply download and flash the ROM image which included USB display driver provided by us.

We provide most of MiniPC SD-card ROM image, you can use some mirror writing tools (windows: Win32DiskImager, Linux / Mac: dd)  to flash the image into SD card.

For those built-in Nand Flash devices (e.g. Cubieboard, most MiniPC TV stick), we offer some packaged nand flash ROM images, using corresponding download tools will flash the ROM image to be stationed into your development edition permanently.

For specific operation details, please take the User Manual as reference.

Advanced Usage: Kernel Driver Compilation and Implementation

For those devices we have not yet provided ROM image supported, do not worry, we provide RPUSBDisp Linux kernel driver code. You can follow the bellow documentation or the steps in the README of source code to compile the code into driver to drive RPUSBDisp run on your device.

Experienced User: Customizing Driver

For those customer that our driver cannot meet your requirement, you can also customize more powerful driver according to published USB communication protocol specification from us.

  1. Hi,

    Very attractive device for many applications where size is a factor.
    Like it so much that I would like to purchase one. But where can I obtain one please.

    Best regards

  2. Wonderful product!

    – Is it possible to show programatically bitmap images from a Windows PC on the screen?
    – Do I need to install any Windows driver for this purpose?
    – I plan to show a new bitmap image in every 5 second, while connecting the display and PC with a USB cable only. Is this possible?

    Thanks
    Joe

    1. Hi Joe,
      To display image on Windows is possible, we will release a user-mode SDK very soon:)
      The user-mode SDK for our USB Display is actually a series of DLLs that provides C/C++ APIs to allow you fully control the display on Windows/Linux/Mac.
      We will post more details of this SDK in the following weeks.

  3. Hello,
    I am working on a project to display home automation data (temperature, power usage, intruder alarm etc) on your USB display. To send data to the display, I would like to set up a wireless link using a pair of nRF24L01+. I have already several of those up and running for data aquisition throughout the house – no cabling required 😀
    My impression is that using the USB interface is not so reasonable.
    The datasheet shows that there seems to be a serial interface with Rx / Tx as well (connector and pads on the back of the display). Can this interface be used to control the display ? If so, is there docomentation available ? Can you pleas make this documentation available to me ?

    Thank you very much in advance and best regards

  4. I have one of this displays in my raspberry pi but runs with extremely slow frame rate , i can see the refresh 1 per 1 of the screen.

    Somebody know how to solve this?

  5. Dear sir, we are really interested in your product. we are developing a project and need a 5inch or 7 inch touchscreen, so whether you have any product with bigger screen.

    1. Hi Loc, thanks for your interest in our product. For your bigger screen requirement, exactlly we are developing 5inch solution and will be on sale shortly, we will keep you informed once it’s ready.

  6. Do you have any idea of when you will provide support for the Galileo and offer a bigger screen. My university will be getting a number of Galileo boards and I am looking at options for how to use them, and your screen has potential since the Galileo doesn’t have built in video support.
    thanks

  7. Hello.
    I own one of your LCD’s. I’m new in linuks i i would like to make this LCD work with my OpenElec on Ras Pi. Is there some easy way to make it work. OpenElec dos not have /Lib/modules directory so hov to do it to put there drivers?

  8. Hi:
    I need to ask two questions:
    1) can i rotate the screen using your drivers in a pcDuino
    2) what name has the white connector below the board
    Thanks in regards

  9. Hi

    I second as I want to use this screen with Android Jelly Bean on the Pcduino 3!!! Are there drivers available?

    Regards

  10. Hi,

    I want to announce that I successfully compilled rp_usbdisplay on Odroid U3 running Ubuntu 14.04 LTS using kernel: 3.8.13.23.

    After doing some configuration to framebuffer configs I run links2 and startx running Firefox with Classic Theme Restorer minimalistic settings to hide all bars and display only webpage.

    The X11 does not have any icons and bars since I run it for a reason to fire single application like xterm showing top or measure CPU temp etc.

    But I must say that I have a problem with touchscreen input, ~30s after connecting the display it stops working. Anybody got an idea?

    Also mplayer2 failed to run color conversion properly on framebuffer (no X11!) resulting in garbage colors.

  11. Nvm, did run apt-get update/upgrade, some packages got updated and the touchscreen works all the time 🙂

    Very goog product. Was a little painful to compile it on odroid but it was worth it. 🙂
