MAX21100 MInD SetupMInD does not require any particular setup. It is configured to work at 3.2V with a single supply for the MAX21100. 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.

ToolbarThe toolbar is located on the top of the MInD GUI window (Figure 18).A short description of each toolbar button follows: The Connection management buttons allow the
user to select a MInD device and to open/close a connection to it.
The Console button shows/hides the console window on the bottom side of the main window. The console reports the commands exchanged by the software and the device and the decoded streaming output (if active).
The Views button launches the Views panel contain-ing a set of graphical visualizations of the sensors data (see the Views Panel section).
The Macro management tool permits the user to select a macro and launch its play/pause function (see the Macro section).
The Direct commands tool permits the execution of raw commands on the MInD device.
Views PanelThis panel contains a set of graphical visualizations of the sensors data and gyroscope plot (Figure 19).Using the Views panel, you can select among different dockable views by clicking on the related button of the toolbar on the top of the window. The available views are: Accelerometer Plot: This view shows a plot for the
accelerometer data (Figure 20).

MacroA 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.

MAX21100 Maxim Inertial Demo (MInD) Evaluation Kit
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 the advanced macro manager with macro list (on the left) and the code related to selected macro from the list (on the right).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.
LoggingThe 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).

ISSUE NO. SYMPTON CAUSE SOLUTION
1When 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.
2
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.
3
The LEDs are all red and the firmware upgraders do not show the device in the List of COMs components.
The MInD device is stuck in programming mode.
1) Connect the battery.2) Select the Recovery tab (Figure 35).3) Select the COM port of the connected device
(Figure 36).4) Click the Recovery Board button. The
message shown in Figure 37 should appear.5) Click OK to terminate the procedure.The original firmware has been restored.
4
The firmware upgrader failed to upgrade the firmware and showed the message “Error Loading Firmware.”
The battery is not connected.Connect the battery and apply the solution for Issue 3 above and try to upgrade the new firmware again.
5
The firmware upgrader failed to upgrade the firmware and showed other error messages.
The procedure failed for internal reasons.
Apply the solution for Issue 3 above and then uninstall and reinstall the software.
