Adafruit's new board.

Arduino IDE (sort-of).

Primarily for the C programming Language.

• imported shattuck's forth like interpreter code initially with a git submodule

• modded it severely for clean compile non-functioning

• omitted both submodule dependencies but kept the compiler toolchain submodule available here

  REPEAT: no 'git submodule update --init' used at all, except electively for detailed informational purposes. Nothing there is compiled-against.

The board receives firmware and executes it.

Do use Arduino IDE 2.x to do the firmware upload - arduino-cli did not 'work' and is unknown (in this one git repository) to 'work' completely (it will kick out messages that indicate a conversation has taken place but that's not enough).

Or .. something was overlooked.

• blink LED on GPIO
• print to the USB serial, messages in English
• operate the NeoPixel

Each of those hit on success yesterday. Did not focus on making gains good (saving code).

Shipment arrived Saturday.

initialize repository, create minimal application, compile (no testing).
