hey, pardon my obliviousness to all things Arduino because I have not actually owned one yet, and I have just a few questions before I commit myself to owning one
suppose that I am trying to create a persistence of vision setup using a TLC5940 , where the images to be displayed is wirelessly transferred via the XBee onto the moving Arduino board and stored in an SpiRAM device
the TLC5940 uses pins 9,10,11 and 13 , while the SPI interface uses 10,11,12 and 13
can the master-out-slave-in (11) pin be shared with more than one component, since both the SpiRAM and the TLC5940 needs it?
and according to http://arduino.cc/en/Main/ArduinoXbeeShield , the XBee shield leaves all the pins above 7 uncovered, can I take this to mean that the XBee can be used concurrently with the TLC5940 and/or an SPI device such as the SpiRAM?
