From the project

Firmware for a portable DAP using a AVR128DA48 and VS1063 chip.

Firmware for a distraction‑free portable audio player built around AVR128DA48.

No networking. No background services. Boot fast, play audio.

The primary development environment is curiositynano`, which targets the Microchip Curiosity Nano board and uses UPDI for flashing.

Available environments: - curiositynano (Main Development) - Curiosity Nano target with UPDI upload - avr128da48 - generic AVR128DA48 build - curiositynanossd1333minimal - controller smoke test for the SSD1333 panel
