Linux command line to update HMI display
Posted: Fri Jan 24, 2020 10:43 pm
Hello, I haven't used Matrix Orbital stuff, but I have used Nextion displays in a previous factory test automation project and I love the HMI display concept.
Would it be possible to make a Linux command-line program to download the display file for the HMI display? The reason this is important to me is because my testers can get deployed to remote locations and I don't use Windows. My testers run on Linux embedded computers and Raspberry Pi's.
I don't mind developing the GUI on Windows (as long as it works fine with Windows on a VM), but I really want to be able to update the HMI display remotely without Windows, something akin to microcontroller programming tools via the command line. This way, I can update the HMI displays of remote testers just over an SSH connection, or using bash scripts or other automation tools.
I asked a similar question to 4D Systems and they had no such tool. I asked if they could provide specs on the download protocol so I can write a downloader and they wanted me to sign an NDA to tell me how to the download protocol worked.
This seemed rather silly to me because I would think manufacturers would want to open source the download protocol so folks can write their own open-source programming utilities for their displays and help out all users. All I want to do is get the updated HMI file into the display without a giant desktop OS running.
Please let me know your thoughts. Thanks, -Vince
