Teensy Time Example

Instructions for building with a teensy40 board.

Build/Flash/Serial

Create the out build directory.

gn gen out --export-compile-commands --args='
    pw_arduino_build_BOARD="teensy40"
    pw_arduino_build_CORE_PATH="//third_party/pigweed/third_party/arduino/cores"
    pw_arduino_build_CORE_NAME="teensy"
    pw_arduino_build_PACKAGE_NAME = "teensy/avr"
    pw_arduino_use_test_server=false'

Run the compile.
```
ninja -C out
```

Flash.

arduino_unit_test_runner \
  --config out/arduino_debug/gen/arduino_builder_config.json \
  --upload-tool teensyloader \
  --verbose \
  --flash-only \
  out/arduino_debug/obj/source/teensy_time/bin/teensy_time.elf

Single line:

arduino_unit_test_runner --config out/arduino_debug/gen/arduino_builder_config.json --upload-tool teensyloader --verbose --flash-only out/arduino_debug/obj/source/teensy_time/bin/teensy_time.elf

Tail the output. If using plaintext logging using pw_log_BACKEND = "$dir_pw_log_basic" use miniterm, (use Ctrl-] to quit).

python -m serial.tools.miniterm --raw - 115200

You should see something like:

$ python -m serial.tools.miniterm --raw - 115200
--- Available ports:
---  1: /dev/ttyACM0         'USB Serial'
