My display arrived early this week. I have it monitoring both cgminer instances with this quick-and-dirty shell script that just alternates between the two:
#!/bin/sh
while [ 1 == 1 ]
do
python cgminerLCDStats.py -d 15 &
sleep 10
kill $(ps auxw | grep cgminerLCDStats.py | grep -v grep | awk '{print $2}')
python cgminerLCDStats.py -d 15 -p 4029 &
sleep 10
kill $(ps auxw | grep cgminerLCDStats.py | grep -v grep | awk '{print $2}')
done
Port 4028 (the default) is an scrypt mining instance with a Radeon 6870 and a Radeon 7750. Port 4029 is an SHA-256 mining instance with a couple of BFL Jalapeños. Every 10 seconds, it reads one and displays it. The running instance is then killed and the other one is started.
The only real downside is that the display is cleared once every 10 seconds. I'm also not sure that more information (as from two miners at once) could be displayed without some lower-level mucking around in the display software to make the text smaller. Perhaps rendering text (in a smaller font) to an image and uploading that to the display would work.
Very, VERY cool
It's nice to see people getting some use out of this!
Yeah, the text size isn't something you can set, at least with the library code I've looked at. As you say, the next best bet would be to render up an image in the background and then display it. Kinda old school style
As for the screen blanking every time it's restarted - you could try commenting out line 341 in cgminerLCDStats.py:
# display.clear_lines(TextLines.ALL, BackgroundColours.BLACK)
Not sure that will work as expected, but it's worth a try.
Thanks for sharing your tip for monitoring multiple instances. I'll try and add that to the readme.
was shipped from HK yesterday but i have to wait 20~30 days before it will be in my hand
