PT6315 VFD driver (192 segm max), Keyboard scan (32 max).
Lib for the PT6315 Vacuum Fluorescent Display (VFD) driver. The lib also provides a class to use the PT6315 as found in DVDR3510 player. SPi Interface.
Vacuum Fluorescent Displays (VFD) have been around for quite some time, but they are still popular. You will find them in audio and video equipment (eg DVD players), Point-Of-Sale stations, car displays etc. They are not cheap, unless produced in large numbers. However, they look good since they have nice bright colors and are readable in daylight. The best known types are the seven segment displays (e.g. alarmclock radios). These types can all display numbers 0-9 and some characters like A-F. The 14- or 16- segment 'starburst' displays are more suitable when you need more flexibility to display characters or symbols. This library interfaces to a PT6315 VFD controller that supports multiple display modes from 4 digits of 24 segments to 12 digits of 16 segments (192 segm). It has internal memory for all digits and will continuously output that data to the display. It supports dimming (brightness control) and has additional 4 LED outputs and a 16x2 keyboard matrix scan. The device can be controlled by SPI bus.
