MAX5498 Evaluation Kit
The MAX5498 EV kit software graphical user interface
(GUI) is a Windows program that provides a convenient
means to control the MAX5498 (Figure 1).
Pressing the Factory Reset button returns wipers 1
and 2 (and the nonvolatile memory) to the midscale tap
position.
In the Channel 1 group box, set the tap value (either by
typing the decimal tap number into one of the edit
boxes or by moving the track bar), and then press the
Write button.
In the Channel 2 group box, set the tap value (either by
typing the decimal tap number into one of the edit
boxes or by moving the track bar), and then press the
Write button.
As confirmation, the Command History window shows
the executed SPI sequence. The first hex value is the
command byte sent to the device and the next two hex
values correspond to the W-L tap value (e.g., SPI: 0x01,
0x80, 0x00).
In the Channel 1 group box, set the tap value (either by
typing the decimal tap number into one of the edit
boxes or by moving the track bar), and then press the
Write NV button.
In the Channel 2 group box, set the tap value (either by
typing the decimal tap number into one of the edit
boxes or by moving the track bar), and then press the
Write NV button.
As confirmation, the Command History group box
diaplays the executed SPI sequence. The first hex
value is the command byte sent to the device and the
next two hex values correspond to the W-L tap value
(e.g., SPI: 0x11, 0x80, 0x00).
