Installation
- Install the current upstream Arduino IDE at the 1.8.7 level or later. The current version is at the Arduino website.
- Start Arduino and open Preferences window.
- Enter
https://raw.githubusercontent.com/xukangmin/TinyCore/master/avr/package/package_tinycore_index.jsoninto Additional Board Manager URLs field. You can add multiple URLs, separating them with commas. - Open Boards Manager from Tools > Board menu and install TinyCore platform (and don't forget to select your TinyCore board from Tools > Board menu after installation).
Programming
There are several ways to upload sketches.
Upload through TinyCore Programmer
- Select related com port number and click upload directly, same as programming Arduino Uno
Upload through Arduino Uno or similar boards
- Connect Arduno Uno and Tiny Core boards as described here.
- Arduin IDE->Tools->Programmer->Arduino PIN as UPDI
- Arduin IDE->Sketch->Upload using programer
Upload through Atmel-ICE Programmer
- Connect Atmel-ICE UPDI, VTG and GND PIN to TinyCore, supply TinyCore with external voltage, either 3.3V or 5V.
- Make sure the green light on Atmel-ICE is on, that means target is properly powered
- Arduin IDE->Tools->Programer->Atmel-ICE-UPDI
- Arduin IDE->Sketch->Upload using programer
Pin Mapping
- Tiny Core 16 Pinout
- Tiny Core 32 Pinout
