DigiView User's Guide
Enabled Status -
Indicates the enabled state of the signal. When the lightbulb is ON, the signal is enabled.
Click this button to toggle the "enabled" status of the signal. This value can also be changed
by editing the signal's properties. (see: Signal Editors 10 )
Associated Channels -
All channels associated with this signal definition will be indicated in this display as a blue
"dot". Channel 0 is in the farthest right column and channel 17 (or 35) is in the farthest left
column (as marked in the header.) Light blue lines appear every 4th channel and non
associated channels appear as '-' as a reference. Also, colored squares at the top show
each channel's wire color. Notice that there are only 9 colors so the color sequence repeats
(channels 0 and 9 are both brown - the color Black is used for ground connections).
Signal Editors
DigiView provides several "Signal" type definitions which allow unique methods of interpreting and
displaying the raw data captured on the logic channels. Each Signal type has a unique editor with
relevant options for its type. From the editor you will also assign some of the physical logic
channels to be used for this new signal definition. (see: Signals 8 , Connecting Data Lines 6 )
You may choose to repeat the use of some channels in multiple Signal definitions in order to
interpret the data differently and gain a perspective that is relative to your current point of interest.
This can be done easily by creating a new Signal using the definition with the properties you
require. Using the same channels in multiple definitions will not have any effect on the actual
capture, but can greatly increase your ability to analyze the data and present visual representation
to others.
NOTE: For your convenience, the signal editors display a darker background on channels that are
already assigned to other signals. However, the same channel can be assigned to as many signal
definitions as you need. For instance, if you want to capture the Read and Write cycles of an SPI
bus using separate signal definitions (instead of the combined read/write of the SPI signal type),
you can create 2 Synchronous Serial signals and assign the same channel as the Clock for each
definition.
The currently available Signal Types are listed below. Details of each type's properties are
described in the following sections.
Multiple channels combined to a single analog view.
Serial UART analysis, pre-selected and custom baud rates, channel inversion option, from 4
to 8 bit selectable, parity option, Framing options and Glitch filter.
Single channel viewing.
Bus 12
Multi-channel viewing.
