This journey begins when one day I got a free Grove Starter Kit (Gen2).
My studying mates are my Macbook, Arduino Uno R4, and using the official CLI for operation. All steps are following the guides in official website.
It is necessary to install the package, called the core, in arduino ecosystem. This software pack is based the board, to install the accurate one on your PC, first check your board.
// Linked the board to PC
$ arduino-cli board list
Port Protocol Type Board Name FQBN Core
/dev/cu.usbmodem14101 serial Serial Port (USB) Arduino UNO R4 Minima arduino:renesas_uno:minima arduino:renesas_uno
In the label core, you can now know the name is arduino:renesas_uno.
Port and FQBN is also essential parameters when we run the promgram, would need to check frequently if you forget.
Then, installing the core by following command:
$ arduino-cli core install $CORE_NAME
// Verified the installed cores
$ $ arduino-cli core list
ID Installed Latest Name
arduino:renesas_uno 1.2.0 1.2.0 Arduino UNO R4 Boards
- Compile a sketch
$ arduino-cli compile -b arduino:renesas_uno:minima scanner/
with a library
- Upload a sketch
$ arduino-cli upload -p /dev/cu.usbmodem14401 --fqbn arduino:renesas_uno:minima scanner
- Others: install a package
Based on the official documents,
single click -> stop the power shortly and rerun the stored sketch, memory is cleaned.
double click -> Go to boatloader mode: waiting a new sketch coming, actually the stored sketch is still there.
By uploading a clean sketch
