Subject: arachnid-labs-re-load-pro: Handle undervoltage condition.
X-Git-Tag: libsigrok-0.5.0~560
X-Git-Url: https://sigrok.org/gitaction?a=commitdiff_plain;h=2217be1dd452ec00ac3c59e2db60f6b088593761;p=libsigrok.git

arachnid-labs-re-load-pro: Handle undervoltage condition.

Support the SR_CONF_UNDER_VOLTAGE_CONDITION* keys.

Undervoltage (and overtemperature) conditions now emit a
warning-level message as well.
