; MCU : ATtiny3226 (tinyAVR 2-series)
|

; Programmer: jtag2updi
|
|
; =====================================================
|
|
; The "atmelmegaavr" platform already bundles megaTinyCore
|
|
; under the hood for ATtiny3226 — do NOT add board_build.core
|
|
; or platform_packages overrides; doing so breaks the package
|
|
; resolver (KeyError: framework-arduino-megaavr-megtinycore).
|
|
;
|
|
; If USART2 (or any 2-series-only peripheral) is reported as
|
|
; "not declared", update the platform package instead:
|
|
; pio pkg update
|
|
; pio platform update atmelmegaavr
|
|
; This refreshes the underlying board manifests/io headers.
|
|
;
|
|
; Update upload_port / monitor_port below to match your system:
|
|
; Windows : COM3, COM4, ...
|
|
; Linux : /dev/ttyUSB0, /dev/ttyACM0
|
|
; macOS : /dev/cu.usbserial-*, /dev/cu.usbmodem*
