Conguration
The Master Control File can direct Flyer to read the state of all eight digital inputs or it
can congure Flyer to read up to 16 bit states using a multiplexed scheme. FH Flyer inputs
and their corresponding decimal and hexadecimal equivalents are shown below. For clar-
ity, hexadecimal values are preceded with an “0x” prex.
Lower byte (LSB):
Input IN7 IN6 IN5 IN4 IN3 IN2 IN1 IN0
Decimal value 128 64 32 16 8 4 2 1
Hex value 0x80 0x40 0x20 0x10 0x08 0x04 0x02 0x01
Upper byte (MSB):
Input IN7 IN6 IN5 IN4 IN3 IN2 IN1 IN0
Decimal value 32768 16384 8192 4096 2048 1024 512 256
Hex value 0x8000 0x4000 0x2000 0x1000 0x0800 0x0400 0x0200 0x0100
Example: When reading only one byte (eight bits) and the active input state is:
Input IN7 IN6 IN5 IN4 IN3 IN2 IN1 IN0
Input state 0 0 0 0 1 1 1 1
this corresponds to decimal 15 (8 + 4 + 2 + 1 =15) or hexadecimal 0x0F.
The Master Control File can direct Flyer to set the state of all eight digital outputs. FH
Flyer outputs and their corresponding decimal and hexadecimal equivalents are shown
below. For clarity, hexadecimal values are preceded with an “0x” prex.
Output OUT7 OUT6 OUT5 OUT4 OUT3 OUT2 OUT1 OUT0
Decimal value 128 64 32 16 8 4 2 1
Hex value 0x80 0x40 0x20 0x10 0x08 0x04 0x02 0x01
Example: You need to set output OUT7 high (active) to indicate a particular condition.
If OUT7 is the only active output, then this state corresponds to decimal 128
or hexadecimal 0x80.
Output OUT7 OUT6 OUT5 OUT4 OUT3 OUT2 OUT1 OUT0
Output state 1 0 0 0 0 0 0 0
