Raspberry Pi 5 and Electromage Output Expander

[reedsearle]

I have recently been working with a Raspberry Pi 5 and LED strips to show Java student a visual demonstration of sorting methods. I eventually stumbled on this site and bought the Output Extender from Electromage. I was having trouble making the combination work until I noticed the following line in PixelblazeOutputExtender.java:
helper = new PixelBlazeOutputExpanderHelper("/dev/ttyS0");
The Pi 5 does not have a /dev/ttyS0 as the UART conflicts from previous version have been resolved. I modified the code to be:
helper = new PixelBlazeOutputExpanderHelper("/dev/ttyAMA0");
Now, the neopixels work perfectly.

Could a note be added to the Pixelblaze page to reflect this?

Thanks @reedsearle and @taartspi for this info and the update of the website. I also added this info now in the jbang example code as a comment.
