Graphical User Interface (GUI) Panel

The MAX5393 EV kit software GUI shown in Figure 1 is

a Windows program that provides a convenient means

to control the MAX5393 dual potentiometer. Use the

mouse or press the Tab key to navigate through the GUI

controls. The correct SPI write operations are generated

to update the MAX5393 internal memory registers when

any of these controls are executed.

Software Startup

Upon startup, the EV kit software automatically searches

for the USB interface board’s circuit connection. In the

Interface group box, the Device_Connected combo box

allows the user to select the proper part being evalu-

ated. Upon selection of the device being evaluated, the

Update_Pot_A_and_B checkbox is enabled/disabled. The

EV kit enters the normal operating mode when the USB

connection is detected and the part has been selected.

Since the MAX5393 does not have read capability, all

of the edit boxes are set to question marks (??) and the

Potentiometerꢀ track bars are set to midscale. If the

USB connection is not detected, the software prompts

the user to retry, exit the program, or enter the demo

mode.

The software divides the EV kit functions into group

boxes. The Interface group box indicates the EV kit

Status and the last write operation Command_ Sent

and Data_ Sent indicators. This data confirms proper

device operation. The Device_ Connected combo box

selects the Maxim part being evaluated and enables

the Update_ Pot_ A_ and_ B checkbox function when

choosing the MAX5393 option from the list. The Default

button programs both potentiometers to their midscale

Demo Mode

Status Indicator

The EV kit software enters the demo mode, when the

USB connection is not detected, by selecting Cancel on

the MAX5393_ Evaluation_ Kit_ Interface_ Circuit popup

window (Figure 2). The software can also enter demo

mode at any time from the main window by selecting

the Options_|_Demo_Mode menu item. When in demo

mode, all software communication to the EV kit circuit

is disabled; however, most of the software GUI is func-

tional. Demo mode allows the user to evaluate the soft-

ware without hardware connectivity. To exit demo mode,

deselect the Options_|_Demo_Mode menu item.

The Status indicator in the Interface group box displays

EV_Kit_Operational when the EV kit enters the normal

operating mode after the USB connection is detected.

If the USB connection is not detected, or when the

software enters the demo mode, the Status indicator

displays Demo_Mode. Demo mode is used to exercise

the software without hardware connectivity.

Command Sent Indicator

The Command_Sent indicator in the Interface group box

displays the last command sent from the master (soft-

ware) to the MAX5393. There are three SPI commands

available in the MAX5393 IC, which Table 2 describes.

Potentiometer A and B Wiper Positions

The wiper position track bars (WA, WB) in the

Potentiometer_ A and Potentiometer_ B group boxes

are used to independently change the wiper position

between the H_ and L_ end points. Use the computer

mouse or arrow keys to move the wiper position_between

the 256 position points. The wiper position can also be

changed by entering the desired integer value in the

edit boxes, or by pressing the up or down arrows in the

respective edit box. A change in the Wꢀ wiper position_

track bars, or HWꢀ/WLꢀ edit boxes writes to the regis-

ters and the wiper position is updated with the data sent.

The wiper position is shown in the HWꢀ and WLꢀ edit

boxes. The HWꢀ edit box shows the wiper position with

respect to the potentiometer H end point and the WLꢀ

edit box shows the wiper position with respect to the

potentiometer L_ end point.

Data Sent Indicator

The Data_Sent indicator displays the last data sent for

the write to potentiometer A (0x00), potentiometer B

(0x01), or both potentiometer A and B (0x03) commands.

The MAX5393 IC uses an 8-bit (MSBs, D7:D0) data byte

to set the wiper position. Refer to the MAX5391/MAX5393

IC data sheet for additional information.

Keyboard Navigation

Press the Tab key to select each GUI control. The select-

ed control is indicated by a dotted outline. Pressing Shift

+ Tab moves the selection to the previously selected

control. Buttons respond to the keyboard’s space bar

and some controls respond to the keyboard’s up-and-

down arrow keys. Activate the program’s menu bar by

pressing the F10 key and then pressing the letter of the

desired menu item. Most menu items have one letter

underlined, indicating their shortcut key.

Potentiometers A and B can be updated simultane-

ously by checking the Update_Pot_A_and_B checkbox.

When enabled, the Potentiometer_A group box sends

the same data to both of the digital potentiometers and

enables control of both digital potentiometers together.

When a number is entered into the edit boxes, it can be

sent to the device by pressing the Enter key. It is also

sent when Tab or Shift + Tab is pressed.

Factory Default

Pressing the Default button resets potentiometer A and

B wiper positions in the MAX5393 to the factory-default

midscale position.

Simple SPI Commands

There are two methods for communicating with the EV

the 3-Wire_Interface (Figure 3) utility from the main pro-

gram’s Options_|_Advanced_Users Interface menu bar.

A window is displayed that allows SPI send/receive data

operations.

The Send_ and_ Receive_ Data group box allows the

user to send data to the MAX5393. The Data_bytes_to_

be_written_edit box indicates data to be sent from the

master (microcontroller) to the device (MAX5393). Eight-

bit hexadecimal numbers should be comma delimited.

Press the Send_Now button to transmit the data from the

master to the device. Data appearing in the Data_bytes_

received edit box is data read from the device. The Data_

bytes_ received edit box in the EV kit software always

shows a default value of 0xFF since the MAX5393 does

not send data back to the master.

On the 3-wire_ interface tab, the Connection group

box defines the hardware connections of the interface.

For the EV kit, K10 is selected from the Clock_ (SCK)_

(SCLK) drop-down list, K12 from the Data_ from_

master_ to_ slave_ (MOSI)_ (DIN) drop-down list, K11

from the Data_ from_ slave_ to_ master_ (MISO)_ (DOUT)

drop-down list, K9 from the Chip-select_(CS)_for_data_

framing drop-down list, and the Use_standard_connec-

tions_ for_ high-speed_ SPI checkbox is checked (see

Figure 3).

Note: The SPI dialog boxes accept numeric data in

hexadecimal format. Hexadecimal numbers must be

prefixed by $ or 0x. Figure 3 shows a simple SPI write-

byte operation using the included 3-wire interface diag-

nostics tool. In this example, the software is sending

command 0x11 (write to potentiometers A and B) and

data 0x7F. The data sequence sets potentiometer A and

B wiper positions to 127.

The Configuration group box allows the user to config-

ure the logic level and data rate. For the MAX5393 EV

kit, check the Send_&_Receive_MSB_first checkbox and

verify that the CPOL=1_(clock_idle_high) and CPHA=1_

(sample_ 2nd_ edge) checkboxes are unchecked (see

Figure 3).

General Troubleshooting

EV Kit VDD Input Source

Problem:_Software_reports_it_cannot_find_the_interface_

circuit:

The VPOWER rail is typically supplied as 3.3V or 5V by

the MINIQUSB+ interface board circuitry or 2.6V using

LDO regulator U6. LDO regulator U5 output is set to 1.7V

and is powered from the VPOWER rail. The VPOWER rail

and U5 are used to set the MAX5393 VDD input to 5V,

3.3V, 2.6V, or 1.7V.

•

Is the USB cable connected to the MINIQUSB+ board?

• Has Windows plug-and-play detected the board?

Bring up Control_Panel->System->Device_Manager,

and look at what device nodes are indicated for USB.

If there is an Unknown_ device_ node attached to

the USB, uninstall it—this forces plug-and-play to try

again.

Regulator U5 has an adjustable output that can be con-

figured to a different voltage by replacing resistor R1.

Use the following equation to set U5 output voltage:

VOUT

1.225





•

If using an off-board SPI interface, is the power ground

connected to the EV kit ground (GND) at one of the

header J1 pin connections (J1-2, J1-4, J1-6, or J1-8)?

R1 = 10

where R1 is in ohms and VOUT is the desired U5 output

voltage.

Detailed Description of Hardware

Jumper JU20 selects the source for the MAX5393 EV

kit circuit VPOWER rail. See Table 3 for proper jumper

configuration for setting VPOWER rail.

The MAX5393 EV kit is an assembled and tested PCB

that features the MAX5393M 256-tap, 50kI, dual digital

potentiometer. Each wiper can be programmed inde-

pendently among 256 tap positions. The EV kit uses a

MAX5393M in a 16-pin TSSOP package on a proven

two-layer PCB design.

Alternatively, the EV kit’s VDD PCB pad can be used to

supply an external 1.7V to 5.25V to the circuit’s VPOWER

rail, by removing the shunt at jumper JU20.

Jumper JU1 enables/disables U5 output. Install a shunt

across JU1 to enable U5 1.7V output. Remove the shunt

at JU1 to disable U5 output. See Table 4 for proper JU1

configuration.

The EV kit provides connector J1 to interface with the

MAX5393 CS, DIN, SCLK, and GND signals directly to

a user-supplied 3-wire system. Connector J1 also pro-

vides a connection for the EV kit’s 1.7V to 5.5V VPOWER

power-supply input.

Note:_LDO U6 output is disabled when the MINIQUSB+

board is not installed at headers J1 and J2.

The EV kit is typically used with a MINIQUSB+ interface

board for communicating with a PC through the 3-wire

serial interface. Logic-level translators U7 and U8 pro-

vide proper SPI interface translation when using 1.7V to

5.5V to power the MAX5393 VDD input.

MAX5393 Evaluation System

Potentiometer, Voltage-Divider or Variable Resistor,

with Ground Reference

MAX5393 VDD Input Configuration

Jumper JU19 selects the power source for the MAX5393

VDD input. Install a shunt across pins 1-2 to set the

MAX5393 VDD input to 1.7V. Install a shunt across pins

2-3 to set the MAX5393 VDD input to the VPOWER rail.

See Table 5 for proper jumper configuration for the

MAX5393 VDD power-supply input.

The EV kit provides an option to configure the MAX5393

as a potentiometer or voltage-divider, open-ended or

with ground reference, respectively. Use jumpers JU12

and JU13 for potentiometer A, and jumpers JU14 and

JU15 for potentiometer B configurations. See Tables 7

and 8 for jumper options for configuring potentiometers

A and B.

SPI Clock and Data-/Chip-Select Inputs

The MAX5393 features a clock and data-/chip-select

input pins for SPI-compatible communication to control

the wiper position. The clock and data-/chip-select pins

can be driven by the MINIQUSB+ interface circuit or the

PCB header (J1), along with a user-supplied external

SPI-compatible controller. An external SPI-compatible

controller can be connected to CS (J1-3), DIN (J1-5),

SCLK (J1-7), and GND (J1-2, J1-4, J1-6, J1-8) on header

J1 to communicate with the MAX5393 IC. When using

an external SPI-compatible controller, verify that the

MINIQUSB+ interface board has been disconnected

from the EV kit’s J2 and J3 headers. See Table 5 for

header J1 pin assignment.

The MAX5393 IC can also be configured as a variable

resistor by shorting the H_ and W_ pads together using

a wire. When operating as a variable resistor, any power

source connected to the H_, W_, or L_ pads must be

voltage and current limited to the maximum conditions

stated in the MAX5391/MAX5393 IC data sheet.

Note:_To test the device in resistor mode, the ohmmeter

must be GND referenced to the MAX5393. This can be

accomplished by connecting the L_ pin to GND or the H_

pin to VDD. Resistance can then be measured between

W_ and L_ or W_ and H_PCB pads.

Evaluating the MAX5386M/

MAX5388/MAX5391 ICs

The EV kit is populated with additional PCB footprints

(U1, U2, and U4) and various jumpers to evaluate the

MAX5386M, MAX5391, and MAX5388, respectively.

Note: It is recommended that the CS, DIN, and SCLK

signals not drive more than one device at any given time.
