logic

On-device logic analyzer waveform viewer. It displays the latest capture made by the shared logic analyzer service or the SUMP job. With pin arguments it makes a new local capture before opening the viewer.

Usage:

logic
logic <pin[,pin...]> [rate-hz] [samples] [trigger=<pin>]

Examples:

logic
logic 1,2,3,17
logic 1,2 500000 8192
logic 1,2,3,17 10000 4096 trigger=1

trigger=<pin> waits for the next rising or falling edge on that runtime-safe GPIO before sampling. The trigger pin may be one of the captured data pins, as in the last example, or a separate GPIO that is not displayed as a channel.

Controls:

• Left/Right pans through the capture.
• +/- or Page Up/Page Down changes the time scale.
• r captures again with the current local configuration when the SUMP job is

stopped.

• a or Home shows the complete capture.
• q, Esc, or the app-exit key exits.

The app is compiled only for boards with graphics and runtime-safe GPIOs. While the SUMP job is running, the app remains a viewer and automatically reloads captures received from the host.
