SolarOS 4.17.7 manual · job

sump

SUMP-compatible logic analyzer server on cdc0. It claims the CDC port and uses the shared logic analyzer service for acquisition. PulseView and sigrok can connect with the OpenBench Logic Sniffer/SUMP serial driver.

Usage:

job start sump [pin ...]
job start sump [pin[,pin...]]
job stop sump
job status sump

Examples:

job start sump
job start sump 1 2 3 17
job start sump 1,2,3,17

If no pins are supplied, the job uses up to eight runtime-safe GPIOs from the active board profile. Host commands select the sample rate and capture size. The current implementation supports 10 kHz to 2 MHz requests and up to 32768 one-byte samples; the status recorded with each capture reports the measured effective rate.

Notes:

• The job requires both CDC and runtime-safe GPIO capabilities.
• cdc0 cannot be used by a port shell, logger, bridge, or another job while SUMP is active. Start SUMP from the display shell, SSH, or another port after stopping any shell attached to cdc0.
• Basic trigger commands are accepted for host compatibility, but this first implementation captures immediately instead of waiting for a trigger.
• Captures remain available to the logic app after the job stops.
