These instructions were tested with:
- Ubuntu 22.04 x86-64.
- Arduino IDE 2.3.2 installed from .zip file.
- SendOnlySoftwareSerial commit a1d3d44110a6.
- Compilation verified, but actually running the code not verified.
Download the Arduino IDE from https://www.arduino.cc/en/software.
Run the IDE. Open preferences: File menu -> Preferences menu item.
Make a note of the "Sketchbook location". At least on Linux, this defaults to
~/Arduino. Use this path in the commands below.
Add http://drazzy.com/package_drazzy.com_index.json to "Additional boards
(sic) manager URLs".
Click OK. You might need to restart the IDE,
Toole menu > Board > Boards Manager. Search for ATTinyCore. Click Install.
Tools menu > Board > ATTinyCore > ATTiny 25/45/85 (no bootloader). A lot of other config options will show up in the tools menu. I assume the defaults will work fine.
Run the commands below to get a dependency library. Unfortunately, the libraries can't be part of the sketch directory despite what the IDE docs say in some places (at least for older versions; maybe that feature got removed in more recent versions.)
mkdir -p ~/Arduino/libraries
cd ~/Arduino/libraries
git clone https://github.com/nickgammon/SendOnlySoftwareSerial.gitClick the "verify" button to build the project.
Click the "upload" button to build the project then upload it to an attached device.
TODO: automate all of the above using arduino-cli and Docker.
