Test program for LS7366 expansion board for the WSE SBC for quad encoder interfaces. Uses the LS7366LIB device class.
mbed WSE SBC LS7366 quadrature encoder interface expansion board using the LS7366LIB library
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.
