README

md-classic-display

This project is a modern replacement for classic LCD displays in Sony MiniDisc portables. It uses an ATTiny1614 controller with a TPS61046 boost circuit for driving an SSD1306 OLED.

The protocol is documented here: https://github.com/MiniDisc-wiki/md-firmware/wiki/LCD-SPI-protocol-(NetMD-devices)

Confirmed to work with: MZ-N510, MZ-N520, MZ-N505. Should work on all Sony NetMD devices (non-himd), and most likely will work on older devices (the MZ-R700 uses the exact samedisplay protocol, I only haven't tested it).

How to use

Connect the OLED board to the SPI lines on the MD display board. VCC on the display board isn't stable enough, you should connect to a stable voltage line on the MD controller board (such as VCC for the remote, VCO1 on the MZ-N510).

What needs to be improved

  • I haven't implemented custom glyph support yet, so my tetris / raycaster demos will not work with this display
  • There can be minor lag between two display updates, which sometimes is visible when text is scrolling. Can be fixed by updating the display in a slightly smarter way.
  • Themes would be cool
