Crate teensycore
source · [−]Expand description
A kernel for teensy-4.0 microcontroller.
This crate provides all the resources necessary to begin interfacing with the teensy-4.0. To get started, you simply need to use the main! macro. This will perform a number of chores for you including the following:
- Initialize uart, xbar, gpio, system clock
- Enable interrupts
- Add panic handling
- Verify memory access
- Enable FPU
Modules
This module provides the ability to designate any two gpio pins as SDA/SCL which allows you to introduce i2c capabilities into your project.
This module represents basic math functionality that you might find useful in a kernel.
Mem
Phys module handles kernel-level interfacing for physical, on-board peripherals.
This module represents the serial communication protocol based on UART physical hardware.
System
Macros
This method will call the asm! macro but
in a way that doesn’t break tests. Use it
in lieu of the asm! macro.
This is the primary macro necessary to bootstrap your application. It takes a code block that will be used as the entrypoint to your logic.
A thin wrapper around Str::with_content($X)
This macro takes a static string and returns a vector containing the sequence of characters.
This macro returns a vector of the items you pass to it.
Enums
Constants
Returns how many nanos are in a microsecond
Returns how many nanos are in a millisecond
Returns how many nanos are in a second
Traits
Functions
This function returns a u32 containing the program counter of the line of code which invokes this function.
Data Memory Barrier
Use this method to enter a system-wide failure event.
Instruction Synchronization Barrier
This method will intiate a pendsv interrupt
This method will wait a certain amount of milliseconds
by calculating how many nop commands it will take
and issuing them sequentially.
Waits for a specific amount of nanoseconds.
