Joseph Bradshaw / Mbed 2 deprecated mbed_QUAD_ENCLIB_TEST

Test program for LS7366 expansion board for the WSE SBC for quad encoder interfaces. Uses the LS7366LIB device class.

Dependencies:   LS7366LIB mbed

This printed circuit board connects 2 LS7366 SPI encoder interface IC's to the mbed WSE SBC. The LS7366LIB library allows the user to instantiate encoder objects with chip selects on p27 and p28 to expand the two encoder interfaces on the WSE SBC to 4.
