Figure 41. Download Failed
There are three reasons that a download may fail:
•
The ADE71xx/ADE75xx/ADE51xx/ADE55xx is not
powered up correctly.
•
The communication failed.
•
The part was not in serial download mode.
Ensure that the ADE71xx/ADE75xx/ADE51xx/ADE55xx is
receiving 3.3 V from either the 9 V dc power supply or the
220 V line power. If using the 9 V dc power supply, this can be
verified using an oscilloscope or voltmeter to probe both the
V
DD
and V
INTD
pins.
Ensure that the USB-to-UART board connects to the P2 header
and the necessary drivers are installed (see the Installing the
Drivers section). To verify communication has been established,
use the procedure outlined in the HyperTerminal
Communication
section.
Place the part in serial download mode once again by pressing
the push-button sequence described in the Launching the
Evaluation Software section.

Figure 42 shows the main menu of the ADE71xx/ADE75xx
evaluation software. The COM port address and the ID string
of the ADE71xx/ADE75xx part detected during the download
process are displayed on this window. The left option box lists
the functional blocks that can be tested using this software.

option should be chosen. Selecting this option causes the series
of prompts described in the Launching the Evaluation Software
section to appear. The
Exit
option causes the evaluation soft-
ware to stop running.
Each of the remaining
MAIN MENU
options, with the excep-
tion of the
Metering Functions
option, causes a new window to
appear in front of the main menu window. Clicking the
EXIT
button in the new window brings you back to the main menu
window. Register values are not reset by the program when a
new window opens or closes. Clicking the
Metering Functions
option opens a secondary menu with more evaluation options.
These options are described in the Metering Menu section.
