DEFINITION

Register Window

Scrolling text box that displays the address and data for the I2C registers that are defined for the device

Address Edit Box

Contains the I2C subaddress that will be accessed using the Write and Read buttons. Clicking on a row selects

an address, which then appears in the address edit box.

 

 

NOTE: After clicking on a row, the Data Edit box contains the data that was in the register window. The device

 

has not yet been read.

 

The address up/down arrows are used to jump to the next/previous subaddress that is defined for the device. If

 

an address is not defined for the device, it can still be accessed by typing the subaddress in the Address Edit

 

box.

Data Edit Box

Contains the data which will be written to, or was read from, the I2C subaddress.

 

The data up/down arrows increment/decrement the data value by 1.

Write Button

Writes the byte in the Data Edit box to the address in the Address Edit box.

 

The I2C register is written to whether or not the data is different from the last time the register was read.

Read Button

Reads the data from the address in the Address Edit box into the Data Edit box and the register window.

Read All Button

Reads all defined readable registers from the device and updates the register window.

Hex Button

Converts all values in the register window and address and data edit boxes to hexadecimal.

Dec Button

Close Button

NOTE: Multiple edit register map windows can be open at the same time (one for each device). Use the

 

Window menu to navigate.
