DS4404 Evaluation Kit

Software Startup

If the DS4404 EV kit is connected when the software

is opened, the software first initializes the hardware to

communicate. The software then searches for all slave

addresses on the I2C bus and connects to the first valid

slave address. The GUI displays

EV Kit Hardware

Connected in the bottom right-hand corner. If the EV

kit is not connected on software startup, then the GUI

populates with default EV kit values. Once the EV kit is

connected, the GUI executes the sequence above.

Menu and Status Bar

The

File menu item contains an exit option. To exit, select

Exit. The Device menu item allows the user to connect

to a desired device.

Find Slave Addresses searches for

all slave addresses connected to the I2C bus. To select

a device, click

Select Slave Address and all the slave

addresses found are shown and are selectable.

Status Log

The status log located at the bottom left-hand side of the

GUI displays all the actions the GUI performs. Whenever

an I2C command is read or written, the action is

confirmed by the log. The log can be cleared by clicking

on the

Clear button.

Status Tab

The

Status tab, located on the bottom of the GUI,

displays the current status, EV kit software version, and

whether or not the hardware is connected.

Communicating with the Device

To read and write from the selected slave address, there

are two buttons labeled

Read and Write. Clicking the

Read button updates the four register values displayed

on the GUI. All values are represented in a hexadecimal

format. To send data, type or use the up/down arrows to

adjust the registers to the appropriate values. Then click
