EVALUATION SOFTWARE FUNCTIONS

The ADE7953 evaluation software allows access to all registers

and features of the ADE7953 using SPI, I2C, or UART communi-

cation. The communication mode and speed should be set in the

main window (see Figure 7). The menu options available are

•

Active Energy

•

Reactive Energy

•

Apparent Energy

•

Waveform Sampling

•

Interrupts

•

Power Quality Information

•

Read and Write Registers

•

Access All Registers

•

Reset ADE7953

•

EXIT (stops LabVIEW)

These options provide access to all internal registers and allow

the evaluation of ADE7953 performance. To access these func-

tions, click the desired option in the MENU box (see Figure 7).

Clicking an option in the MENU box displays a window where

the specific function can be accessed. Each window includes an

EXIT button that should be used to return to the main window.

Note that only one option from the MENU box can be open at a

time; click EXIT to return to the main window before choosing

another option from the MENU box.

ACTIVE ENERGY

The Active Energy window is shown in Figure 10. This window

allows access to all registers associated with the active energy

measurement.

The tabs at the top of the window allow registers associated

with Current Channel A or Current Channel B to be accessed.

A register can be read by clicking READ All Registers. Register

modifications can be made directly on the signal path diagram;

these modifications are written to the part by clicking WRITE

All Registers.

From the Active Energy window, the CF Outputs window can

be accessed by clicking CF Output. Clicking CF Output opens

the window shown in Figure 9.

Figure 9. CF Outputs Window

From this window, the functionality of the CF1 and CF2 output

pins can be selected.
