in 2014 we were asked by textile dept to hack their industrial weaving machine.
its vamatex industrial weaving machine

we are trying to get a WIF (WEAVING INFORMATION FILE) into its memory cards directly from a WIF editor.

==== the problem ====

currently the only method to upload patterns to the machine is by export to image/text file from a pc and then write it line by line to the UV EPROM card \\

that means countless hours of writing line by line into the eeprom writer\\
