E-ink reader as external display
Dear all,
Maybe this is just another project of making an e-reader external display, but I didn't find any similar solution. The objectives of the project are: - The device is placed in the factory at the entrance to one of departments. - The device is displaying the list of logged in employees so anybody who visits the department can see who is "on duty". - Upon evacuation, the rescue supervisor grabs the device so the rescue team has got a list of employees which were inside before the alarm. - The display is refreshing - let's say once a minute - when put into place and freezes when grabbed. - Minimum modification of reader's software and maximum reliability working 24/7/365. Preliminarly I thought about two options: 1. Connect the reader by WiFi to the company network and prepare the web page in company intranet. Run the page on reader's web browser. Question: If I set i.e. <meta http-equiv="Refresh" content="60" /> will it work on Pocketbook's browser? 2. Connet the reader to the PC which will upload once a minute the file with the content to display (text, html, bmp, whatever). This makes the reader independent from WiFi network operation and sure the content would freeze when disconnected. Question: Is there a program for Pocketbook to display any content which will refresh it at desired time interval or when the content is overwritten? I don't feel convenient to write any software by myself, I did never program in Linux. It is possible to purchase the program from european company which can issue vat invoice. Best regards. |

E-ink reader as external display
Hi,
this functionality does not seem too complicated to me. I see a big problem however concerning reliability: If we create a program, it always relies on the pocketbook's firmware and it's programming interface "inkview". We have no influence on crashing system libs or the underlying Linux kernel. If that's OK for you, i guess it would be no problem to write a tool, like you decribed: it should be possible to periodically "wget" a bmp or png file from a web server running on a pc in your company's Intranet and push it to the framebuffer. Of course the web server will have to periodically update the image - but that's on the PC's side, where programming is much easier than on your pocketbook. |
