Arduino Nano 33 IOT Board Support Crate

This crate provides a type-safe API for working with the Arduino nano 33 IOT board.

Examples

Blinky Basic

Requirements

• Arduino IDE installed
  • samd package installed
  • Now the arduino distribution contains bossac.exe in ArduinoData/packages/arduino/tools/bossac/1.7.0/ add it to your path
    • ArduinoData is likely something like ~/.arduino15/
  • Probably best to install an example sketch via the IDE just to make sure everything is working
  • Note that the arduino cli (or just regular bossac) may soon replace this section
• arm-none-eabi tools installed, you need gcc and objcopy.
• thumbv6m-none-eabi rust target installed via rustup target add thumbv6m-none-eabi

Steps

cargo build --release --example blinky_basic
arm-none-eabi-objcopy -O binary target/thumbv6m-none-eabi/release/examples/blinky_basic target/blinky_basic.bin
bossac -i -d -U true -i -e -w -v target/blinky_basic.bin -R

(You may need to use --port with something like /dev/ttyACM0 or /dev/ttyACM1

Notes

• It may help to double-press the center button to reset when re-flashing the device. This sets the device in a bootloader mode.
• For the usb example, picocom is a good simple terminal serial emulator
