so i would hold a pin high on the chip i am using and then shiftin
the data as a byte from pins 0-7, and store that data into a variable?

Make that INL and INH for proper compilation.

I was assuming the counter chip was a parallel output.....What is the number
of the counter chip you are using to count, and explain a little about your
application. The Stamp does have a COUNT instruction.

the chip i am using is a LS7166, i am attempting to use this to read
quadrature outputs from an encoder, i beleive the data output is
parallel, 24 bit, the data is sent in three bytes

Pins 0~7 can be read as IN LOW, while 8~ 15 IN HIGH.

hi guys, how would one read 8 data pins from a counter chip?
