ESPer-CDP

meku

ESPer-CDP platform dev board with IDE bus
ESP32-WROVER with ESP32 REV 3 or newer, with 8MB QIO Flash and 4MB QIO PSRAM (HIMEM is not used currently)
ESPer Keypad
Futaba GP1232A02 VFD display (take it out of a broken arcade cabinet… or write a driver for something less obscure, but preferably also VFD :-)
IR remote receiver + PS2 DVD remote
optional: Nixierator module for track # display (not yet implemented)

Recommended: NEC ND-3500A: just works in every aspect, and even has CD TEXT! Wish every one of the others was like this.
Philips/Lite-On DH-20A4P aka Buffalo DVSM-XE1219FB: Load a bit on the slow side, noisy mech! Janky ffwd/rewind (using software timer because the drive doesn’t do SCAN commands).
MATSHITADVD-RAM SW-9583S: Works mostly. No SPDIF output even though the jack is there?? Do we need to alter the Mode Select page?
TEAC DV-W58G: works and reads CD TEXT, janky ffwd/rewind (same as DH-20A4P). Most of the initial development was done with this drive. SPDIF output noisy during initial spin-up and pause release, or my unit just too old/faulty?
Matsushita SR-8171 (slimline): mostly works. TOC read after disc change is unstable (goes through on 3rd retry, timing/busyflag issue?) Needs a standard JAE 50pin to IDE 40pin adapter. Does not require 12V supply. Analog output only.

Matsushita/Panasonic SW-9590C: never initializes, never sets DRQ, faulty unit?

NEC CDR-1400C: kinda works, very unstable state management, sometimes freezes the whole system, doesn’t report media type codes properly.
TEAC CD-C68E: works including changer, sometimes TOC reads are broken, workaround is in place but still. No SPDIF output, so you have to resort to analog. As of V1.0a it’s become significantly more glitchy and I have no idea why. TBD in a future release…
ALi DVD Ver0.96A_0104: found inside a MUSTEK DVD player. Plays it seems but no SPDIF. Cannot stop without being paused first. Overall weird behavior.

Read CD audio TOC from an IDE drive
Ask the drive to play/pause and skip tracks (sequential playback only for now)
Read CD TEXT if the drive supports it (only English/UTF8 block is supported)
Display CD metadata found online through Musicbrainz, or GnuDB — using real libcddb ported to ESP32, lol
Cache CD metadata in Flash (no cleanup when storage runs out yet… but with compression you can fit an average CD collection in there with ease)
Display timed lyrics for the songs using the awesome LRCLib
Receive internet radio stations (as long as no crazy bitrate) in MP3 and AAC formats with up to 6 station presets
Receive sound over Bluetooth (SBC only) and control the remote device
Settings UI on screen with multiple language support: English, Japanese, Russian, feel free to add your own?
IR Remote (PS2-DVD remote)
Scrobbling to Last.FM
