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.
