Subject: tests: extend endianess conversion tests to also cover the 48bit writer
X-Git-Url: https://sigrok.org/gitaction?a=commitdiff_plain;h=8f87c5284bf05c14e125f0cd6c292417d0decbbe;p=libsigrok.git

tests: extend endianess conversion tests to also cover the 48bit writer

Cover the recently added writer for 48bit little endian data. Prepare a
large bytes pattern buffer that can also serve for future 64bit tests.
