20) The EV kit is now ready for further evaluation.
The MAX11068 EV kit is evaluated in conjunction with
the MAX11068 evaluation software. The graphical user
interface (GUI) provides a friendly environment for read-
ing and writing to all device registers, as well as execut-
ing the seven device commands. The GUI is divided into
three sections, Initialization group box, register tabs,
and command tabs.
The Initialization_ group box provides controls for the
HELLOALL, ROLLCALL, and SETLASTADDRESS com-
mands, as well as device-shutdown capability. The
command tabs, located in the upper-right section of
the GUI, provide controls for executing the WRITEALL,
READALL, and STROBEALL commands. This group of
tabs also includes a Device_Address grid that displays

Note: Jumper designators JU27 and JU127 are not used on
this EV kit.

the address of each device in the SMBus ladder, a
Communication_ Log that displays a summary of bus
activity, and a Short_Cuts tab that provides faster ways
of executing useful software functions.
The seven register tabs provide access to all the devices
in the SMBus ladder. Each tab includes a grid that is
used to display the contents read from the registers. The
grid is made of x columns and y rows, where x is the
number of registers (shown above each grid) associ-
ated with that tab and y is the number of devices in the
SMBus ladder. In addition, each tab includes various
controls (checkboxes, edit boxes, buttons, labels, etc.)
for configuring each device. Refer to the I
and Register Map sections in the MAX11068 IC data
sheet for additional interface and register details.
The software also provides a few functions to facilitate
the evaluation process. These include a PEC calculator,
the capability to save ADC measurements to file, and the
ability to save/load register configurations to/from a file.
When evaluating the EV kit, the MAX11068 IC data sheet
should also be referenced for additional details.
The SMBus ladder of the EV kit is initialized using the
controls provided in the Initialization group box on the
EV kit software GUI. The recommended initialization
sequence is as follows:
