LPD 8806 raspberry pi

LPD8806 datasheet
https://cdn-shop.adafruit.com/datasheets/lpd8806+english.pdf

LPD8806 strips have input side and output sides.

Arduino
https://cdn-learn.adafruit.com/downloads/pdf/digital-led-strip.pdf

https://www.raspberrypi.org/documentation/hardware/raspberrypi/spi/README.md

SPI test
https://elixir.bootlin.com/linux/latest/source/tools/spi/spidev_test.c

https://pypi.org/project/raspi.lpd8806/

alright. LPD8806 can only support upto 20MHz
Default RPi3 SPI clock is 125MHz.

change SPI clock
https://www.raspberrypi.org/forums/viewtopic.php?t=177965

https://github.com/ManiacalLabs/BiblioPixel

OK:
Raspberry pi 1 or zero or zero W. works w/ py-spidev & RPi-LPD8806

spidev and examples
https://github.com/doceme/py-spidev
https://www.programcreek.com/python/example/105717/spidev.SpiDev
RPi LPD8806
https://github.com/longjos/RPi-LPD8806

Raspberry pi 3 does not even w/ 500KHz or lower SPI clock. spitest shows SPI port behaves normal. It could be a py-spidev problem. Not sure.
