A "bit" pin which is TRUE can have any nonzero value, not just 1. So
the line
bit_shifted = (bit_in << which_bit);
is incorrect. Instead, you may wish to write something like
if(bit_in)
accum = accum | (1 << which_bit);
to avoid the confusion. (I prefer "|" (bitwise OR) to "+" (a
rflow, and the shift will
happen with a strange number of bits).

Kirk-
How are you simulating the input in the office?

I have the a serial ADC setup and mostly working, but I have a problem
with the output value being too high. I shift bit 11 through 0 into a
byte as shown below.
