Module teensy4_pins::common[−][src]

Expand description

Common pinout

The Teensy 4.0 and 4.1 share many pins. This module provides the pins that are common across both boards. For pins that are unique to each board, and to acquire all of a board’s pins, see the t40 and t41 modules.

Common pin table

This table describes all common pins and their possible functions. Besides this table, there are two other ways to identify which pads support which peripheral:

study the i.MX RT 1060 Reference Manual. This is the authority on pad configuration.
study the trait implementations for the pad. Select a pin type alias, like P0, and click-through to its pad documentation (AD_B0_03). Notice the listing of imxrt-iomuxc trait implementations. This describes what kinds of functions the pin supports. The constraints may be enforced by the HAL’s APIs.
