On the last line, all of the switches will switch at once. The most significant bit of
highByte will control OUT15 and the least significant bit will control OUT8 and
likewise for lowByte, OUT7 and OUT0.
Daisy Chaining
This shield is designed to be
daisy-chained in order to get
greatly expanded numbers of high
current outputs. This requires a
cable of the type shown in Figure
4. All of the pins are carried over,
with the exception of SIN & SOUT
(pins 8 & 7, respectively). SOUT of
the source shield must be
connected to SIN of the next
shield, and so on down the chain.
If you're using IDC connectors with ribbon cable to make your daisy chain cable, this is
straightforward. Assemble the first connector normally. At the second connector,
separate and swap conductors seven and eight. After assembling the connector, cut
conductor seven (now plugged into pin eight of the second connector) downstream of
the second connector and conductor eight (now plugged into pin seven of the second
connector) upstream of the connector. Assemble the third connector normally, but after
you have assembled it, trim conductor eight downstream and conductor seven
upstream. Assemble the fourth connector as you did the second and the fifth as you did
