I downloaded last available compass beta version today and installed it (beta 5).
Just plugged DRAWS hat on RPi 3B+, connected Din6 cable into left din6 plug and YAESU FT-7900 and set APRS frequency.
Starting direwolf -t 0 allowed immediate display of APRS trafic.
After editing direwolf.conf for BEACON to advertize my location and direwolf started digipeating APRS packets.
Some remarks about CARD name and din6 identification labelling:
aplay -l displays harware plugHW: CARD=udrc, DEV=0
Same for direwolf and n7nix/deviation/measure_deviate.sh in the menu and at various places
instead of DRAWS.
measure_deviate uses by default LEFT din6 (audio channel 0) that he advertizes as connector hd15 and PTT gpio 12
Same with option measure_deviate -c hd15
Starting measure_deviate -c din6
activates RIGHT din6 plug (audio channel 1) using PTT gpio 23
Using HD15 may confuse new DRAWS customers for there is no such plug.
