What even is this?

HDA2040 is a project aiming to allow an RP2040 to talk to audio codecs using the Intel HDA (HD Audio) protocol

Software

• current state: like 2/10
• core functionality (WIP)
• usb sound card functionality (planned)
• circuit/micropython library (planned)

Hardware

PROTO1:

• basically speedran design while drinking 7up at 1am (no, not sponsored, 7up is amazing)
• flawed
• trash
• works despite the 3 above points
• basically a test
• STM32F103 as an in circuit debugger (Blackmagic Probe based)
• RP2040 as main CPU
• 16MB flash
• ALC887 codec
• minimal
• basically every pin broken out
• janky

More hardware (less janky at that) coming soon™
