leon912 Posted January 27, 2016 Report Share Posted January 27, 2016 Hi, does anyone know how it is possible to exchange data between the papilio pro board and the PC. Thanks Quote Link to comment Share on other sites More sharing options...
Jack Gassett Posted January 27, 2016 Report Share Posted January 27, 2016 Regular Serial communications using a sketch running on the ZPUino is the easiest way. Jack. Quote Link to comment Share on other sites More sharing options...
leon912 Posted January 28, 2016 Author Report Share Posted January 28, 2016 Hi, what if I would like to create a VHDL entity simulating the USB? Since the Papilio is provided with USB connector and a transceiver module, I want to establish a communication by using only VHDL code Quote Link to comment Share on other sites More sharing options...

leon912 Posted February 4, 2016 Author Report Share Posted February 4, 2016 Regarding the usb communication, is it possible to use the USB host shield of arduino with the papilio pro? Usually the shields work with 5V but the papilio provides only 3.3 V Quote Link to comment Share on other sites More sharing options...
Jack Gassett Posted February 4, 2016 Report Share Posted February 4, 2016 A 3.3V device can drive 5V logic since 3.3V is high enough to be considered a '1' by 5V logic. For the inputs you will need to put a 390 ohm resistor in series to protect the pin from too much current. With the current limiting resistor it is fine to connect a 5V input to the Papilio boards.
