BiblioPixel on Raspberry PI

Old Google Group Archive
#1

Hello,

because I didn’t need my ambilight anymore I wanted to do something new.
I glued the LPD8806 strip as a matrix on a plate. Then it took me some days to get everything to work on a raspi3b.

Following yaml-code works, but the text runs from the bottom to the top, turned 90 degrees and the letters are mirrored.

How to I rotate and flip the output?

Here is the used code:

shape: [8,20]

driver:
typename: spi
ledtype: LPD8806
num: 160
dev: “/dev/spidev0.0”
interface: PERIPHERY
spi_speed: 4
c_order: GRB

LED order:

01 16 17

02 15 18

03 14 19

04 13 20

05 12 21

06 11 22

07 10 23 and so on…

08 09 24 25

#I think, I need something like this

#layout:

Rotate: 270 (or 90?)

Flip: horizontal

animation:
typename: $bpa.matrix.Text.ScrollText
text: ‘This sentence no verb!’

What is the right solution, I did not find the right hint.

Regards,

Holger

Hello, Holger! Always willing to help a fellow fan of Douglas Hofstadter! :smiley:

Some books still have a place in my book shelf. (See att. :wink: )

Thank you for this very fast help. I managed it with your information. Now I know what I have to do this weekend. I will deal with yaml a bit.

Greetings,

Holger

You should be able to simply add this to your project:

layout:

rotation: 90

y_flip: True

For historical reasons, the twin of y_flip is vert_flip, sorry about that!
