_______________________________________________________________________________________
Quick Start
Recommended Equipment
MAX1168EVC16 (MAX1168EVKIT board and
68HC16MODULE-DIP)
Three DC power supplies:
+8V to +20V at 0.25A
+5V at 0.2A
-5V at 0.2A
Analog signal source:
0 to 4.096V
Windows 95/98/2000/XP-compatible computer with
an available serial (COM) port
9-pin I/O extension cable (straight-through female-
to-male)
Procedure
Do not turn on the power until all connections are
complete:
1) Verify jumper JU1 is ON, disabling DSP mode.
2) Verify jumper JU2 is connected to pins 2
–
3,
enabling an 8-bit-wide data-transfer mode.
3) Carefully connect the boards by aligning the 40-pin
connector of the MAX1168 EV kit with the 40-pin
header of the 68HC16MODULE-DIP module. Gently
press them together. The two boards should be
flush against one another.
4) Ensure that the μC module
’
s SW1 switch is in the
OFF position.
5) Connect the +8V to +20V power supply to the μC
module
’
s terminal block (J2), located next to the
ON/OFF switch (SW1) along the top edge of the μC
module. Observe the polarity marked on the board.
6) Connect the +5V power supply to the VDD pad
(with respect to the GND pad) on the MAX1168 EV
kit board.
7) Connect the -5V power supply to the VEE pad (with
respect to the GND pad) on the MAX1168 EV kit
board.
8) Connect the 9-pin serial cable from the computer
’
s
serial port to the μC module
’
s DB9 connector (J3).
9) Install the MAX1168 EV kit software on your com-
puter by running the INSTALL.EXE program on the
CD-ROM. The program files are copied and icons
are created in the
Programs
section within the
Windows
Start
menu.
10)Turn on the +5V power supply. Next, turn on the -5V
power supply. Finally, turn on the +8V to +20V
power supply and turn on the μC module
’
s slide
switch SW1 to the ON position.
11)Start the MAX1168 EV kit program by clicking on its
icon in the
Programs
section within the Windows
Start
menu.
12)The Windows program will prompt you to click
OK
for
Automatic
serial port selection. When you click
OK
, the Windows program automatically downloads
the file KIT1168.C16 to the module. Please wait
approximately 25 seconds for the download to
complete.
13)Apply an input signal (0 to +4.096V) between AIN0
and GND. Observe the AIN0 label on the running
Windows program.
Detailed Description of Software
The evaluation software
’
s main window shown in Figure
1 displays the voltage and code of the analog-input
signals AIN0
–
AIN7. The software supports manual read
or automatic read operations. Separate comboboxes
allow quick modifications to the MAX1168
’
s control
byte. The SPI
serial clock frequency is adjustable
from 4.19MHz to 33kHz, and the software
’
s reference
value can be changed to match the applied external
reference. The provided Windows-compatible software
supports SPI mode (not DSP mode) and also only sup-
ports the MAX1168 EV kit when configured in 8-bit-
wide data-transfer mode. Table 1 describes all the con-
trols on the evaluation software
’
s main window.
