MCU Compatibility

ViewPoint supports three memory profiles: Minimal, Lite, and Full. On current builds, small AVR boards auto-select VIEWPOINT_MINIMAL, Mega 2560 and UNO R4-class Renesas boards auto-select VIEWPOINT_LITE, and most other 32-bit boards default to VIEWPOINT_FULL unless the sketch overrides the profile before #include <ViewPoint.h>. Use this table as the current support snapshot for the Arduino library:

Board / Family	Suggested Profile	Core Library	VoidLoop SignalCore	Verification Status	Notes
Teensy 4.1	Full	Verified	Verified	Hardware verified	Primary reference platform and main development target
Arduino Giga R1	Full	Verified	Verified	Hardware verified	DSP path tested on hardware
ESP32 Dev Module	Full	Verified	Build-verified	Partial hardware verification	Many core features tested on hardware; DSP currently compile-verified only
Arduino UNO Q	Full	Verified	Build-verified	Partial hardware verification	Uses the Zephyr core
Raspberry Pi Pico	Full	Verified	Verified	Hardware verified	Both Arduino board profiles tested
STM32 Nucleo-F446RE	Full	Build-verified	Build-verified	Hardware unverified	Current STM32 status is based on STM32duino compile checks
AVR Uno, Nano, Leonardo, Micro	Minimal	Build-verified	Not recommended	Limited / unverified	Basic plotting compiles, but SRAM is too tight for the DSP examples

Hardware verified means the sketch was flashed and observed working in ViewPoint. Build-verified means arduino-cli compile succeeded, but runtime testing on the device is still pending. Community contributions are welcomed on the forum threads by board type!
