Evaluation Kit
General Description
The MAX21000 Maxim inertial demo (MInD) evalua-
tion kit (EV kit) allows evaluating the performance of the
MAX21000 ultra-accurate, low-power, 3-axis digital output
gyroscope.
The MInD EV kit provides a complete ecosystem
composed of hardware and software to evaluate the
gyroscope using a PC.
Using the USB connection and a PC, it is possible to evalu-
ate the main important parameters and configurations of
the device.

MAX21000 MInD Setup
MInD does not require any particular setup. It is configured
to work at 3.2V with a single supply for the MAX21000.
See the schematics if different settings are required.
The current consumption is measured using the drop
voltageonresistorR28(20Ω).Foramoreaccuratecur-
rent estimation, measure the resistor and insert it in the
corresponding box of the MInD tab of the GUI.
By inserting and removing STAMP from the PLCC28
socket, some electrical contact issues can be
identified. These can be solved, improving the folding of
thePLCC28pins,asshowninFigure1.

Macro
A macro is a set of commands that can be executed
through the selection of its identifier. The macro feature
provided by the software permits the user to run an exist-
ing macro, record a new one, and save the current con-
figuration as a macro.
Each macro is composed of two functions: play and
pause. The play button on the Macro management sec-
tion of the toolbar (see the Toolbar section) triggers the
execution of the play function; the Pause button triggers
the execution of the pause function. The macro to be
executed can be selected using the drop-down list in the
Macro management section.
Toplayamacro:
● SelectthedesiredmacrofromtheSelect the macro
drop-down list in the Macro management section of
the toolbar.
● ClickthePlay button in the Macro management sec-
tion of the toolbar to execute the play function of the
macro.
● Click the Pause button in the Macro management
section of the toolbar to execute the pause function of
the macro.
Recording a macro means that every write operation
executed using the Tabs frame is saved in a macro. Note
that the write operation executed using the Direct com-
mands tool are not recorded.
Torecordamacro:
● OpentheMacro menu.
● ClickontheRecord a macro menu entry.
● Insertthenameofthenewmacrointhedialogwindow
and click OK.
If a valid name is set, the recording starts.
If the name is not valid, an error message appears
and the name is requested again.
● Executeallthewriteoperationsyouwanttostore.
● OpentheMacro menu.
● ClickontheRecord a macro menu entry to stop the
recording.
Whentherecordingisterminated,allthewriteoperations
are stored in the play function of the created macro. To
recall the recorded macro, select it from the Select the
macro drop-down and click the Play button.
The macro feature also permits the user to save the cur-
rent status of the registers in a macro.
Tosavethecurrentregister’sstatusasamacro:
● OpentheMacro menu.
● ClickontheSave as macro… menu entry.
● Insertthenameofthenewmacrointhedialogwindow
and click OK.
If a valid name is set, the register status is saved in
a new macro.
If the name is not valid, an error message appears
and the name is requested again.
The Macro management tool also provides an interface
to manage the macros. The Advanced macro man-
ager interface permits the user to manually create a new
macro, edit, modify, or delete an existing macro, and to
check the syntax of a macro.
A macro in the MInD software is a set of instructions
written in a Javascript-like language. Almost all the basic
instructions of Javascript are provided, so refer to a
Javascript reference guide for a list of available instruc-
tions. To add the software functionalities, a new object
called mind hasbeenintegrated.Thisobjectprovidesthe
followingfunctions:
● ReadRegister(<device name>, <bank address>, <reg-
ister address>):returnsaregistervalue;
● WriteRegister(<device name>, <bank address>, <reg-
ister address>, <data to write>) :write a value on a
register;
● print(<string to print>) :printsthespecifiedstringinthe
Output text area.
Some other external functions could be released together
with the software; you can find their definition in the util-
func.js file on the root installation folder. Currently, only
the sleep(time) function is provided; it introduced a delay
oftimemsintheexecution.Foranexampleofcode,see
Figure26.
To open the Advanced macro manager:
● OpentheMacro menu.
● ClickontheAdvanced macro manager menu entry.
Figure26 shows the Advanced macro manager interface.
The interface is composed by a toolbar on the top that
provides all the functionalities of the Advanced macro
manager, the list of available macros on the left, a text
editor to show the macro content on the right, and a
debugging output text area on the bottom.

The toolbar offers the following functionalities (from left
toright):
● Create a new macro: Creates an empty macro and
adds it on the list of available macros.
● Save the current macro: Saves the currently edited
macro.
● Deleteamacro:Deletesthecurrentlyselectedmacro.
● Checkmacrosyntax:Checksifthesyntaxofthecur-
rently edited macro is correct.
Figure26 shows an example of macro, which increments
the value of the SENSE LOW PASS BW field of the
SENS_CFG_1registerevery500ms.
Note that the behavior of the Play button of the Advanced
macro manager is different from the behavior of the Play
button of the main window, in that it executes the script
as is, without calling a specific function; so, if you want to
debug a function you have to call it inside the code (as
shownintheexample).Whenthedebuggingiscomplete,
you should delete the call instruction.
Maxim Integrated strongly suggests that you write your
code inside a play or pause function, in order to permit the
execution from outside the Advanced macro manager.
Logging
The logging feature permits the user to save the captured
data from the MInD device to a desired text file. The log-
ging options are available by clicking on the Logging
menu at the top of the GUI window (Figure27).
Clicking on the Configure menu entry allows the user to
select the destination file for the logging information and
the fields to be saved on the destination file, as shown in
Figure28.
Clicking on the Start/Stop menu entry allows the user to
enable/disabletheloggingonfile.
Note: If you are planning to execute a long-time
logging, it is suggested to keep the 3D view closed (see
the Troubleshooting section for details).

WhenIexecutethe3D
view, everything goes
very slow.
The 3D view uses some graphical
libraries that might not be
compatible with old graphic cards
or with obsolete drivers.
Try to improve the performance or update the
drivers of your graphic card.

If I keep the 3D view
running, the physical
memory consumption
increases continuously.
The 3D libraries cause memory
leakage with some graphical cards.
This problem has not been solved yet. In case
of long running (e.g., if you use the device to log
data for hours), it is suggested to keep the 3D
view closed.

Falling edge condition:
Pull up must be bigger than (Vdd_io_sens - Vol) / Iol where:
Vol = 0.4V typ
Iol = 3mA typ
If Vdd_io_sens = 3.3 pull up must be bigger than 966 ohm
Rising edge condition:
t0.7-t0.3 < 300ns
It depends on RC of the net and load
Pull mup must be less than 300ns/(0.847298* Cbus)

This bridge is a workaround
for MAX8903 issue DNM
R Optional: bridge as workaround for
MAX8625 issue. Mount together wit RO4.
U3 is used for supply. Unmount FL 3 and 4
V_LED is equal to 2.2V.
RSet1 = Rset2 *((V_LED/1.2V) -1)
RSet max=1.5Mohm
Charge current max is 1A setted with Riset.
Formula is: Riset = 1200V/Ichgmax
Ichgmax = 1A -> Riset = 1.2K
Current in DCM mode is given by Ridc.
Formula is: Ridc = 6000V/Idc-max
Idc-max = 1.8A -> Ridc = 3.3K
Thermistor control is not mounted.
THM is set ot gnd.
R95 and RO4 are used for control
VDD_DCDC is equal to 3.1V.
RFeed1 = Rfeed2 *((VDD_DCDC /1.25V) -1)
Rfeed2 = 100K -> RFeed1 =148K
RFeed2=0 for 3.3V out
