I am using pyserial to acquire data from an A/D converter plugged to
my serial port.
my hardware represents analog voltages as 12bit numbers. So, according
to the manufacturer, this number will be stored in two bytes like
Byte1: x x x n1 n2 n3 n4 n5
Byte2: x n6 n7 n8 n9 n10 n11 n12
where x is some other information, and nx are the digits of my number.
My problem is to how to recover my reading from these bytes, since
pyserial gives me a character (string) from each byte... I dont know
how to throw away the unneeded bits and concatenate the remaining
bits to form a number...
