I have a string of 6 DotStar LEDs that I’m trying to drive via my Picade x hat’s hacker port. But for some reason the plasma software doesn’t seem to be working? The software installed perfectly via
curl https://get.pimoroni.com/plasma | bash
I changed the plasma.service file’s output device option to
-o SERIAL:/dev/ttyACM0 to reflect my x hat and I edited the
plasma executable’s LED count from 10 to 6.
After restarting my Picade, the LEDs do not light, which was my first sign that something may not be working properly. Pressing F4 to exit emulation station and typing
plasma makes the LEDs light up perfectly though. (Yes!) However, I’m not returned to the
pi@retropie:#$ command prompt, which I would expect to be. All I get is the following
2020-03-08 16:20:21.267363: Starting plasma in the foreground with framerate 30fps 2020-03-08 16:20:21.267372: Plasma input pipe: /tmp/plasma Opening... Open... 2020-03-08 16:20:21.361884: Loaded pattern file: /etc/plasma/default.png _
Each subsequent press of Enter just returns another underscore. Nothing I type in like
cd\ will return me to the
pi@retropie:#$ prompt, I just get another underscore.
@alphanumeric has been a great help in a OT thread, but we’ve drawn a blank so far, hence this more specific thread. Could anyone offer any advice on why the plasma software isn’t working for me? I feel like that’s the issue here. My LEDs light up fine in a random rainbow fashion. But because
plasma doesn’t seem to be executing properly, I’m unable to run anything else like
plasmactl or even return to emulation station.
Hopefully he won’t mind me @ing him but @Gadgetoid it would be great if you could offer some advice on this, pretty please!
