I have seen a project called LightshowPi using an RPI. I wonder if there is an equivalent using the Libre Computer. I tried installing the Lightshowpi software on the Libre Computer but it fails to fully installed. I’m not familiar enough to get it going.
I was using the Libre Computer AML-S905X-CC. Installed Rasbian on the sd card. I got it to work up to this point. But once I installed the Lightshowpi, the software will not fully install.
Any suggestion or direction of any similar project but using the Libre Computer will greatly appreciated.
You need to post some logs or something. Just saying it fails don’t give us much to go on.
Here’s the log. The installation of pyalsaaudio is failing.

This project relies on WiringPi which a dreadfully written piece of software that we don’t have the bandwidth to support. There’s no future in WiringPi because it does too many things (incorrectly). If the project author for lightshowpi abstracts their software from WiringPi and just use standard Linux interfaces with a simple GPIO map getting interface, we can help get the normal device requirements like GPIO/SPI/I2C/PWM going and create bindings for our boards.
This is a general problem with Raspberry Pi based user developed software. A lot of garbage libraries like WiringPi were written and now a lot of projects depend on them. We cannot in good conscience continue the trend just for compatibility sake because we would be putting engineering resources in supporting the wrong way to do things.
Having said that. Is there an alternative project so I can use the Libre computer to do something similar to the lightshowpi?
The modifications to LightshowPi should not be too extensive and I recommend that you contact the authors about supporting generic SPI interface for their pixel driver instead of using WiringPi. You can link them to this thread.
Taking a brief look at their code, they use WiringPi to enable SPI userspace /dev/spidev0.0
The same can be done on our boards via enter a couple of ldto commands. The rest of the stuff should run as is. I’m not sure about the pyalsaaudio dependency failing but that should be the same as Raspberry Pi since it’s just a userspace library.
