Linux Driver for Imaging Device (Serial, Currently on Windows)

Project Description:

We have an imaging device that currently has a Windows driver, and we need to communicate with it in Linux:

- The device: [url removed, login to view]

The windows driver/sample application has a lot of functionality. We need NONE of this. All we need is:

1. Connect to the device

2. Turn on the lights

3. Capture an image

To do this, the documentation states that you will simply need to simulate a dll function call to:

-Call IO_CaptureImage,

- get image data (Binary), and put it into a buffer, which is 1024*1280*3 in length

The source code of the windows sample application is here:

- [url removed, login to view]

You do not need to worry about any of the OCR functions, etc. All we need is to capture an image. We have documentation from the supplier explaining the interface (appears to be serial?)

You may NOT:

- Just run virtualbox

- Use X (This will be running on a server)

To test:

- I can give you access to TeamViewer to a Ubuntu 14.04 box that currently has the device connected to it. Afterwards, it will be on a VPN where you can SSH to the box all you like

Have a look at the documentation (sorry, some is in Chinese).

Currently, the device is connected through USB on linux and properly appears on the USB Bus:
