Damn quick reply... fixing the formatting...
OK, I just cracked it open to see what I did. I remember it was EXTREMELY easy to wire up.
===================================================== There are 4 conductors in the cable coming from the display:
Red: -> 12VDC (back of the main power barrel) Yellow: -> Pin3 of WRT serial port (1/3/5/7/9=bottom row) Black : -> Pin10 of WRT serial (2/4/6/8/10 top row) Green: N/C =====================================================
For code just echo/cat stuff to /dev/tts/1 .
I had a script where it would awk (print $3 /etc/node.history) into a variable then for loop through with a 1 second delay between entry. If you dont delay it, it just blasts the whole list, and with only 2 rows of display, you watch it scroll REALLY FAST and end up with the last 2 showing.
Then I cron job'd it to run every minute. The issue with 1 minute cron is that if I get into a LARGE mesh, it starts again while the first list is still running, and they start interlace the previoous with the current, so maybe then up it to every 2 minutes, adjust as needed.
Unfortunately, I forgot and blew it all away when I upgraded to 1.0.0. Paul and I worked on it again, but Ill be darned if I can find it now. But there are the basics...
