Years ago I used to have a HD44780 20x4 LCD attached to a media PC via parallel; travel years down the line and we have a HTPC setup which does not have a parallel port.
Reading up on the use of standard USB to parallel convertors as can be bought on ebay etc... most of which will not work with anything other than a printer as they do not support bitbanging.
Something that I have discovered is that a micro controller can be used to bridge the two devices, mimicking something like the Matrix Orbital USB character displays for use with LCD Smartie. Past this, the information I have found is quite limited other than the fact that it can be done and people do use it.
Does anybody know of any information or guides on how to use an Arduino in this way; either connecting a HD44780 in 8-bit mode or via an i2c backpack?
Thank you in advance. Jim
