Crate teensy4_pins
source ·Expand description
Hardware pins for the Teensy 4.0, 4.1 and MicroMod boards
teensy4-pins is designed to the imxrt-iomuxc crate. The pins API constrains
the processor pads to the ones that are available on the Teensy 4.0, 4.1 and MicroMod. It also
exposes type aliases that simplify pin identification in the type system.
Note that this pin API is optional. You are free to configure the pins using the
pad identifiers, instead of the physical pin identifiers. Pads are available directly
from the imxrt-iomuxc crate.
Teensy 4.0
To acquire Teensy 4.0 pins, call t40::from_pads and provide all
of the processor pads:
use teensy4_pins::t40;
let pads = // Handle to all processor pads
let pins = t40::from_pads(pads);Teensy 4.1
The approach is the same as the Teensy 4.0, replacing t40 with t41:
use teensy4_pins::t41;
let pads = // Handle to all processor pads
let pins = t41::from_pads(pads);Teensy MicroMod
The approach is the same as the Teensy 4.0, replacing t40 with tmm:
use teensy4_pins::tmm;
let pads = // Handle to all processor pads
let pins = tmm::from_pads(pads);Safety
The safe APIs expect to work on the only instance of the processor pads. If you don’t have that
available, or you need more flexibility, use the unsafe t40::Pin::new,
t41::Pins::new, or tmm::Pins::new constructor methods
to create an instance that may be aliasing another handle to the pads or pins.
