Package rand implements a cryptographically secure random number generator.

Package tls partially implements TLS 1.2, as specified in RFC 5246, and TLS 1.3, as specified in RFC 8446.

CMSIS abstraction functions.

Connects to an BlinkM I2C RGB LED.

Simplistic example using the DAC on the Circuit Playground Express.

This is a echo console running on the device UART.

This is a echo console running on the os.Stdin and os.Stdout.

this is intended to be used as wasm32-unknown-unknown module.

Example using the i2s hardware interface on the Adafruit Circuit Playground Express to read data from the onboard MEMS microphone.

Connects to an MCP3008 ADC via SPI.

blink program for the BBC micro:bit

This reads from UART1 and outputs to default serial, usually UART0 or USB.

package usb contains the subpackages with USB descriptors and device implementations for standard USB device classes such as the Communcation Data Class (CDC), Human Interface Device (HID), and Audio Device Class (ADC).

package adc is for USB Audio Device Class devices.

package cdc is for USB Communication Device Class devices.

package descriptor is for the USB descriptor definitions.

package hid is for USB Human Interface Devices.

Package debug is a very partially implemented package to allow compilation.

Package interrupt provides access to hardware interrupts.

Stubs for the runtime/trace package

Package volatile provides definitions for volatile loads and stores.
