I would like to use the Edge V for controlling a LED Stripe. I found a toutorial for a Rasp Pie.
| WS2801 LED Stripe | Raspberry Pi | Supply |
|---|---|---|
| 5V | — | +V |
| CK / CI | Pin 23 (SCKL) | — |
| SI / DI | Pin 19 (MOSI) | — |
| GND | Pin 6 (GND) | -V / COM |
What are the corresponding pins on the Edge GPIO for CK -> SCKL and SI -> MOSI?
Regards
Mike
Hello @MikesCo
from the looks of it, I see the device is operating over the SPI interface,
according to the given pin layout from Khadas, I see that these two pins should be suited for the operation
Here:
SPI3_CLK (Highlighted in green)
is the SCKL/CK/CI pin (serial clock signal)
and,
SPI_3_TXD (Highlighted in Pink)
is the MOSI/ SI/ DI (serial Master out slave in)
Hope it solves your query
Good day/ Guten Tag!
P.S please note in linux, you will most likely need to modify the device tree to change the muxed pins from whatever they are to SPI pins…
