Fujitsu VF60 hacking

This kind of VFD display:

Pinout

Display can be used by USB and RS-232.

In USB mode, it requires custom 32-bit drivers (which eventually creates COM port). RS-232 is much easier, described below.

Protocol

9600N1

Basic usage:

• to display something, just send it
• \n to go to next line
• \r to return to begining of line
• \x1b[2J - clear display
• \x1b[y;xH - move cursor to (x, y)
• \x1b\\?LDn - set display brightness, n in [0, 1, 2, 3, 4, 5]
• \b to move cursor back
• \x1b[0K - delete text to the end of line
• to reset display, send something incorrect (such as 0x00 on 4800 baud)

Commands were found out by sniffing serial over USB packets, while running Fujitsu Line Driver Unility. This describes what was found

This PDF is for another display, but most of the commands are working just fine

Python lib

vf60 directory contains simple python library for this display. clock.py is a simple demo app
