Следующая вкладка Si570 USB Control пока в стадии эксперимента, как я понял будет управление синтезатором на Si570 из под самой программы. Extract them into a new directory, and connect the Si570 unit to a USB port. I added then just two pins to the ISE Project from the example to create the connection, but the serial interface (a USB-Uart connection) is not working with that project. Nun sieht es so aus, als ließe sich auch dieser Wert in der Praxis noch deutlich unterschreiten. USB; import ch. This SI570 can be ordered directly from SI Labs, at a cost of about $13 each, but I recommend group buys. 0 port doesn't work, try a USB 2.
