Subject: fx2lafw: Unbreak SR_CONF_LIMIT_SAMPLES for large values (above 2**32)
X-Git-Url: https://sigrok.org/gitaction?a=commitdiff_plain;h=6065d660e04b05e94bc31adc6fe0333ecadb040f;p=libsigrok.git

fx2lafw: Unbreak SR_CONF_LIMIT_SAMPLES for large values (above 2**32)

Capture does not stop for sample count values which exceed the range of
a 32bit type variable. Adjust the data type to 64bit.

How to reproduce: 8MSa/s * 600s -> 4,800,000,000 samples

  $ sigrok-cli -d fx2lafw -o capture.sr --config samplerate=8M --time 600000
