Hi,
another project in progress :
USBLPT : an usb parallel port that behaves like a real parallel port
The board plugs on a dev kit.
This is based on USB2LPT project, high speed version 1.7, based on the Cypress CY7C68013A : https://www-user.tu-chemnitz.de/~heha/basteln … PT/index.en.htm
(it is not the atmega project(low speed version) but the cypress high speed version).
This project has a nice software driver that can emulate a legacy USB port, including input and output instructions.
It will not be a perfect solution, as it is still limited by the USB frame timing, for high speed that is 125us
But I hope we can get quite far with this (for example connected to dosbox and have real opl2 music on a modern laptop over USB)
