X-Git-Tag: libsigrok-0.1.0~550 X-Git-Url: https://sigrok.org/gitaction?a=commitdiff_plain;h=28a35d8ab35483b6d50e5b8404542cc11875fa5d;p=libsigrok.git This commit adds initial support for the Asix Sigma Logic Analyzer. Currently, only 200 MHz is supported, and only with software trigger. Firmware for the device will be distributed separately, with permission from the vendor.
