arduino-cli-based scripts to compile, upload and start serial monitor for Arduino Uno connected through USB.

Why

Scenario. I've just made changes to sketch and want to compile it. Then (if it is compiled) upload to /dev/ttyUSB0. Then start serial monitor for that port at 57600 baud.

This is very typical and there is only one real way to do this:

• gcc, avrdude, screen

  Compile with gcc, upload with avrdude. Terminal program is variable, let it be screen.

  But there hella lot of parameters for gcc.

  So people created Arduino IDE

• Arduino IDE

  Click "compile", click "upload", click "serial monitor". Real easy, I've used it for years.

  But later idgaf to their IDE with code editor. I just wanted compile, upload and monitor.

  I believe I wasn't alone, so arduino-cli existed when I came to it

• arduino-cli

  arduino-cli compile --fqbn arduino:avr:uno .
  arduino-cli upload --fqbn arduino:avr:uno --port /dev/ttyUSB0
  arduino-cli monitor --port /dev/ttyUSB0 --config baudrate=57600
  

  Clean command interface, I've used is for several years.

  But later I wanted to add additional compilation flags, assume board name, assume USB port index.

  So I wrote my custom scripts..

ino

ino

Yeah, just like HQ9+ language! It does exactly what is said in scenario.

But it is reasonably configurable and consists of parts:

• Compile

  ino.pile
  

• Upload

  ino.load 1
  

  Upload to /dev/ttyUSB1. Use 0 or drop argument for /dev/ttyUSB0

• Monitor

  ino.mon 1 115200
  

  Serial monitor for /dev/ttyUSB1 at 115200 baud.

  Defaults are /dev/ttyUSB0 and 57600 baud.

So to execute full chain to second Arduino on /dev/ttyUSB1 working on 115200 baud, call

ino 1 115200

Base library

All arduino-cli-related functionality is located in acli_wrappers.sh. Those ino's are just callers and parameter jugglers.

I encourage you to change implementation. Not design (I think design is okay).

Your stock Arduino firmware not compiles because of -Werror? Remove it! Using 115200 or 9600 by default? Change defaults!

Other boards

It's fixed to Arduino Uno. For other boards, I'd use another names for external callers. lora sounds neat for Esplora btw.

Where to install?

I'm using ~/bin for my scripts. Typical location is /usr/local/bin tho.
