setPins() for rx/tx and cs/irq?

[atestani]

I am using an MCP2515 on an ESP32 and writing code in PlatformIO/VSCode with the Arduino framework. I need to set both rx/tx and cs/irq from the defaults. I see in the API.md that there are two calls to setPins() for both pairs of pins. How does the library know which set of pins I am defining?

That depends on whether you're targetting ESP32 or AVR architecture.
