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	16MHz
Flash	5.87KB
RAM	512B
Vendor	Digistump

Configuration

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

[env:digispark-tiny]
platform = atmelavr
board = digispark-tiny

You can override default Digispark USB settings per build environment using board_*** option, where *** is a JSON object path from board manifest digispark-tiny.json. For example, board_build.mcu, board_build.f_cpu, etc.

[env:digispark-tiny]
platform = atmelavr
board = digispark-tiny

; change microcontroller
board_build.mcu = attiny85

; change MCU frequency
board_build.f_cpu = 16500000L

Debugging

PIO Unified Debugger - “1-click” solution for debugging with a zero configuration.

Warning

You will need to install debug tool drivers depending on your system. Please click on compatible debug tool below for the further instructions and configuration information.

You can switch between debugging Tools & Debug Probes using debug_tool option in “platformio.ini” (Project Configuration File).

Digispark USB has on-board debug probe and IS READY for debugging. You don’t need to use/buy external debug probe.

Compatible Tools	On-board	Default
simavr	Yes	Yes

Frameworks
