Positive Gain Calibration RAM: Entering 7 from the Write
Menu invokes a write communication cycle with the Posi-
tive Gain Calibration RAM. The user will be prompted,
per channel, to enter the data to write. The number of
channels prompted for is determined by the CR<7:5>
bits. The software requires the data be entered in hex,
most signi?cant to least signi?cant format. A Positive
Gain Calibration RAM word is 3 bytes, all bytes must be
entered at the prompt.
Negative Gain Calibration RAM: Entering 8 from the
Write Menu invokes a write communication cycle with the
Negative Gain Calibration RAM. The user will be
prompted, per channel, to enter the data to write. The
number of channels prompted for is determined by the
CR<7:5> bits. The software requires the data be entered
in hex, most signi?cant to least signi?cant format. A Neg-
ative Gain Calibration RAM word is 3 bytes, all bytes
must be entered at the prompt.
Hex Input: Entering 9 from the Write Menu invokes a
series of prompts allowing write access to any HI7188
Register. The user must know the instruction byte infor-
mation for this command to be useful. The user will ?rst
Software Execution
The PORTADR.DAT ?le contains the port identi?cation for
the parallel printer port interfacing the HI7188 Evaluation
Board to the PC. Check the printer port address you are
using and if required, update the PORTADR.DAT ?le. The
DOS MSD command can be used to ?nd the printer port
address. Communication between the Evaluation Board
and the PC is not possible without the proper printer
port address in the PORTADR.DAT ?le.
Also on the diskette is the directory SRCCODE, which con-
tains the evaluation software source code. The source code
was compiled with Borland’s Turbo C++, Version 3. The
project ?le used for compilation is 88EVAL.PRJ. If disc space
is limited, do not load this directory onto the PC disc.
Loading Software - Copy the four ?les (88EVAL.EXE,
TESTALL5.CFG, TESTALLA.CFG and PORTADR.DAT) from
the diskette onto your PC hard drive into the directory of your
choice. The ?le 88EVAL.EXE is the executable program. The
TEST*.CFG ?les are con?guration ?les used during the
boot-up test. They must remain at the same hierarchial level
as the 88EVAL.EXE ?le.
be asked to enter, in hex, the IR byte of the communica-
tion cycle. The IR byte entered will be analyzed. If a read
has been requested (from the Write Menu), an error
message is displayed and execution returns to the Write
Menu. If the IR byte entered is a write operation, the IR is
analyzed for register destination and the user is
prompted to input the data, in hex. The number of hex
digits required at the input prompt is a function of the
destination register and the instruction byte entered.
When the I/O cycle has been completed, execution
returns to the Write Menu.
Towards the bottom of the Write Menu are picks that allow
the user to quickly access the Main Menu, Con?guration
Menu, and Read Menu.
m Main Menu: Entering m from the Write Menu returns
software execution to the Main Menu.
Executing the Program - Change directory (cd) into the
directory containing the 88EVAL.EXE ?le. At the DOS
prompt type 88EVAL [return]. The software reminds the user
to apply power to the board before continuing with a
automatic test that checks the communication capability
between the PC and evaluation board. After completing this
test, the Main Menu is displayed and evaluation of the
HI7188 may continue.
If errors occur during the boot-up test routine, the on chip
memory element that cannot be read will be displayed on the
screen and the user must hit the return key for each failure to
complete the test. If errors occur, an incorrect printer port
identi?cation is usually the problem.

c
Con?guration Menu: Entering c from the Write Menu
When programming the HI7188 con?guration via the Con?g-
returns software execution to the Con?guration Menu.
w Read Menu: Entering w from the Write Menu returns
software execution to the Read Menu.
uration Menu entering c at any of the prompts will return the
user to the Con?guration Menu. This feature is useful if an
undesired input is made allowing the user to quickly restart
con?guring the product without having to answer any further
i
s
I/O Reset: Entering i from the Write Menu sends an
active low signal to the HI7188 RSTI/O pin, clearing the
Serial Interface Controller effectively aborting an ongoing
communication cycle. The Write Menu remains displayed
on the screen.
Reset: Entering s from the Write Menu sends an active
low signal to the HI7188 RST pin, which initializes the
HI7188. The Write Menu remains displayed on the
screen.

questions.
Active Channels Display
The upper right corner of the screen displays the current
number of active channels programmed into the DUT,
regardless of the current menu. This is helpful as a quick
check on the current con?guration of the HI7188.
