Hardware

Platform Atmel AVR: Atmel AVR 8-bit MCUs deliver a unique combination of performance, power efficiency and design flexibility. Optimized to speed time to market-and easily adapt to new ones-they are based on the industry’s most code-efficient architecture for C and assembly programming

Microcontroller	ATTINY85
Frequency	8MHz
Flash	8KB
RAM	512B
Vendor	Adafruit

Configuration

Please use gemma ID for board option in “platformio.ini” (Project Configuration File):

[env:gemma]
platform = atmelavr
board = gemma

You can override default Adafruit Gemma settings per build environment using board_*** option, where *** is a JSON object path from board manifest gemma.json. For example, board_build.mcu, board_build.f_cpu, etc.

[env:gemma]
platform = atmelavr
board = gemma

; change microcontroller
board_build.mcu = attiny85

; change MCU frequency
board_build.f_cpu = 8000000L

Debugging

PIO Unified Debugger currently does not support Adafruit Gemma board.

Frameworks

Name	Description
Arduino	Arduino Wiring-based Framework allows writing cross-platform software to control devices attached to a wide range of Arduino boards to create all kinds of creative coding, interactive objects, spaces or physical experiences.
