Currently mine is working with my Blinkt after doing the git clone. If I decide to start over I will try the curl bash option.
“Removed some misinformation”
I will have a look see at that link you posted, thanks. I ran plasmactl trippy and the pattern changed, but it didn’t stick on a reboot.
EDIT:
It looks like its sudo systemctl stop plasmato turn it off. I had tried plasmactl 0 0 0 and they turned off. They strated back up on a reboot though.
Hi alphanumeric,
Sorry didn’t realise you had neopixels. They have only a data line and no clock, so will be different. I think gizmo1990 has dotstars, which have four wires rather than 3 (i.e a data and clock). I think he needs the GPIO, purely because he said that it worked when he ran /usr/bin/plasma with no options. Maybe I misread though.
Incidently all the patterns are in “/etc/plasma/”. You could just copy the pattern you want to /etc/plasma/default.png to make it stick!
Good luck
This is super confusing! :S I think going from DOS’s file structure to Linux based is confusing me to heck!
Cheekymoomin, thanks for bearing with me here. Are you saying that the directory structure doesn’t matter then?
I’ve typed which plasma and it does indeed say /usr/bin/plasma
I’ve also changed both plasma.service settings to -o GPIO:14:15
However when I restart I still get no lights. And when I run `plasma’ I still get dropped to an underscore, not a correct prompt?
Alphanumeric, I thought the Blinkt uses DotStar’s? It says so on the product page. APA102 pixels
The Blinkt has Data and clock
Actuaslly i think i know whats going on. Go here and look at the picture of how he has his dotstrat wired to the Xhat
He has them wired to the button 7 button 8 pins, which explains why they sort of work with the deafult plasma. Button 7 and button 8 go to GPIO 15 and 14. He should have them wired to the plasma connector on the Picade x.
Hang on, afaik I do have them wired to my picade x. There is no plasma connector on it just a Hacker Header with an Expand section, like this?
Do you have the Pi 3B or Pi 4B version? I ask because the Pi 4B USB C version here shows the Plasma connector
Ahh that’s interesting. No I have aPi 3B version, so no standalone plasma header. But it shouldn’t matter. The LEDs should still be wired up via the hacker header going by Pimoroni’s own instructions.
I have mine plugged into the same btn7 and btn8 on the x-hat. I remember having to switch the wires to get it to work. I think the instructions are wrong for the data and clock. I am definitely using 14 and 15 for my GPIO.
Oooh now that is interesting too! You thnk the clk and data should be switched?
Ok, I’m now on the same page as you too, I was thinking you were using the plasma connector. As I don’t own a Picade of any type.
Yeah, that is super confusing that they’ve included that port but not updated their instructions.
alphanumeric,
That board is interesting. I have a usb-c version, but it hasn’t got that extra header. Maybe pimoroni will soon be offering a marquee add-on!
Here is mine (without extra header):
Thanks for posting that cheekymoomin. Any chance you can confirm switching the DATA and CLK wires?
Currently I have
DATA to BTN7
CLK to BTN8
Ok, that’s interesting, it even has Plasma silk screened on those pins. One of my biggest pet peeves here is out of date documentation. =(
Even so to be honest I didn’t look all that closly at the picade X hat stuff, only at the plasma stuff, and how it applied to my setup. sort of kind of.
Data -> BTN8
Clk -> BTN7
THAT WAS IT!! It seems to work perfectly now!!
Great gizmo1990,
Look forward to seeing pictures of your marquee!
Flipping heck, it was just that. Why haven’t Pimoroni noticed and fixed this mistake before!? Surely everyone who has purchased a plasma kit from them has run into the same issue??
Can’t thank you guys @alphanumeric @cheekymoomin enough for sticking with me!
I totally missed the miss wiring? I’m glad somebody is paying attention.
There is a contact us link on the shop page you could use to report his type of thing. Just put a link to these two threads in it.
https://shop.pimoroni.com/pages/contact-us
The other option is to report it on the github page under issues.
Will do alphanumeric. I’ll send them an email tomorrow morning regarding the mistake.
At the very least I’ve learnt a heck of a lot more than I knew before I started these two threads!
