Subject: uni-t-dmm: Add support for the Voltcraft VC-840.
X-Git-Tag: dsupstream~21
X-Git-Url: https://sigrok.org/gitaction?a=commitdiff_plain;h=695d0e1efa819dc98914ce1baec388c8734e98a7;p=libsigrok.git

uni-t-dmm: Add support for the Voltcraft VC-840.

This DMM is already supported via the serial-dmm driver when using the
RS232 cable. The uni-t-dmm support makes it usable with the USB/HID
cable too.
