Modules

adc
calibration

NVM Software Calibration Area Mapping

clock

Configuring the system clock sources. You will typically need to create an instance of GenericClockController before you can set up most of the peripherals on the atsamd51 device. The other types in this module are used to enforce at compile time that the peripherals have been correctly configured.

delay

Delays

gpio

Working with GPIO pins. The pins are associated with the PORT hardware. This module defines a split method on the PORT type that is used to safely reference the individual pin configuration. The IO pins can be switched into alternate function modes, which routes the pins to different peripherals depending on the mode for the pin. The pin configuration is reflected through the use of type states to make the interface (ideally, or at least practically) impossible to misuse.

pad
pins

ItsyBitsy M4 Express pins

prelude

Import the prelude to gain convenient access to helper traits

pwm
sercom

Working with the SERCOM peripherals.

time

Time units

timer

Working with timer counter hardware

trng

Functions

dotstar_bitbang

Convenience for setting up the dotstar LED using bitbang'ed SPI.

i2c_master

Convenience for setting up the labelled SDA, SCL pins to operate as an I2C master running at the specified frequency.

spi_master

Convenience for setting up the labelled SPI peripheral. This powers up SERCOM1 and configures it for use as an SPI Master in SPI Mode 0.

uart

Convenience for setting up the labelled TX, RX pins to operate as a UART running at the specified frequency.

Attribute Macros

entry

Attribute to declare the entry point of the program
