title: Use two things over GPIO SPI connection on Raspberry Pi
body: <p>I have a 2.8" capacitive TFT screen from and a PN532 RFID reader from Adafruit.  The problem is, they both use SPI. When I use the RFID reader, the screen goes completely white and I have to restart the Pi to get the image back. I have to use the SPI interface on the reader so that I can use the Adafruit library to use it with Python. The screen going white isn't a problem as long as it's only when the RFID reader is in use. Is there anyway to "restart" the screen after using the RFID reader? Any help is appreciated.</p>
