Welcome to week two of the Papilio Introduction Series. This week we are covering one of the key features of the Papilio – the ability to shift peripherals to any I/O pin.
“Possibly the most exciting feature of the Papilio is the ability to shift peripheral functionality to any pin at any time, completely on the fly. Shifting SPI pins allows you to easily connect up to 12 SPI devices at once! Or control multiple stepper motors by shifting PWM outputs! Finally, shifting functionality means you never need to worry about where to connect Wings. Every I/O pin is equal, so go ahead and connect your Wing to any open Wing Slot, the FPGA can shift to accommodate the Wing!”
