The return of the Hybrid Sid Player by xAD/Nightfall & Gianluca Renzi (RetroBit Lab)

Based on the Project and Hardware Schematic by Markus Gritsch released in the years 2011-2015 on the forum dangerousprototypes. Thanks Markus.

Changelog:

v1.22 – 6/2/2023

Note:

• From this release the new versions will be developed and tested on the v2 prototype PCB and no longer on the Breadboard prototype.

Added:

• Software implementation of the new audio Switcher.
• Added a new value (0: Nothing) to the DEFAULT_SID_SOCKET in the configuration file (config.ini).

  # Choose the default SID Socket on bootup (0: Nothing – 1:Socket #1 – 2:Socket #2) – default: 1
  DEFAULT_SID_SOCKET=1

• Added control via MCU of the power-up led. It might come in handy for future implementations.

Updated:

• Updated label on the oled display for the “sid switch” mode, now “sidSet” is written and not just “sid”
• Updated boot screen with the text “sorting files…” if the folder contains too many files (max 800).

Fixed:

• The encoder cannot be used for manual SID SWITCH mode in case the SID tune played is multitunes because the encoder is used to select the songs, so although the “sidset” option will be displayed on the display in this  specific case the selection of the sid socket will not working.
• Logic for the switch of the Socket SID with which to play the song and the consequent LED.
• Default SID Socket if nothing is specified in the config file (config.ini)
• Manual “sid switch” mode, the SID that was played with this mode would stop after 2 minutes and start over.
