I have a very interesting interface card - Longan Nano and a LED stripe WS2815 (12V). As far as I understand, I need to connect to DI pin of the LED stripe some pin from SPI output of the card. As the SPI connector has 6 pins as follows:
- MISO - Master in / Slave Out
- SCK, shift clock
- MOSI - master Out / Slave In
- SS - slave select
and the LED stripe gets SPI data commands...
Am I right that I need to use a Master Out / MOSI pin (i.e. B5 or A7 on the board) to connect with the LED Stripe DI pin?
Thank you for any advice, Vlad.
