Particle Xenon SPI ports


Marcio Montenegro
 

Hi all,
I am developing a new project using Particle Xenon and SPI port 1.
According docs Xenon has 3 dtsi files and  SPI1 is selectable with overlay (SPI).

mesh_feather_spi_spi1.dtsi exposes SPI1 on labeled Feather SPI pins
mesh_feather_spi_spi3.dtsi exposes SPI3 on labeled Feather SPI pins
mesh_feather_spi1_spi3.dtsi exposes SPI3 on labeled Feather SPI1 pins

I'm confused about which pins I should use.The Xenon datasheet shows SPI and SPI3 and not SPI1 .Best regards,

Marcio
