PicoScope 6 User's Guide 77

If the channel you want to use is not listed, enable it first by using the Channels

toolbar.

For each channel that you want to decode, click in the Protocols column. A drop-

down list will appear, containing all the protocols that PicoScope understands. The

list may vary depending on which version of PicoScope you are using. For multi-

channel protocols like I

C and SPI, select the data channel. Any other channels will

be specified later.

Select the protocol you wish to use. A Settings panel for the selected channel will

then appear below the table in the dialog.

Settings panel

The settings panel shows all the adjustable settings for the selected channel. The

options available depend on the protocol selected: see Common settings and Protocol-

specific settings.

Information panel

You do not need to take action on the messages in this panel. If the number of

samples is too small then PicoScope will automatically adjust the capture settings to

improve the signal quality. If the number of samples is larger than necessary, this is

harmless and no adjustment will be made.

Common settings

These settings apply to all serial data formats.

Refresh. When you have entered the necessary information, PicoScope

analyzes the incoming signal and chooses the best settings for serial decoding. If

PicoScope is unable to decode the data, try improving the signal quality and then

click the Refresh button to analyze the signal again. For best results, click the

Auto Setup button in the Capture Setup toolbar in the main PicoScope window

before entering serial decoding mode. This will ensure that the signal is captured

with enough detail for accurate decoding.

Display. Choose where you want to display the data: In View, In Window, or

both.

In View shows the data in logic-analyzer style, on the same time axis as the

analog waveform.

Hover the mouse pointer over any decoded packet to display its contents.

Click-and-drag the decoded data up or down the scope view.

If the In Window display is visible, double-click on any packet to highlight

it in the table.

In Window displays the decoded data in a table in the serial data window,

with advanced search and filtering functions.
