Using an SPI interface only consumes three or four of the pi’s pins depending on how you wire it. This is a 2×16 character display that interfaces via SPI or Parallel. The first thing to do was to select an appropriate display. They often have a blue/green character color. They differ from LCDs in that LCD displays typically have a backlight whereas a VFD emits light directly, in a similar manner to how a fluorescent light works. VFDs are an older technology that has existed since the early 1960s. VFD stands for “Vacuum Fluorescent Display”. I figured just to be different I would try a VFD display. There were many options for a display - I could go with an LCD, an OLED, etc. 1000 1000 1000 1000 8 700 PART NUMBER: REVISION: CIG LCD EMULATORS A.I’m in the process of building a home automation controller using my Raspberry Pi, and I figured it would be cool if it could display the current song and artist on my Pandora player. A 10K pull-up resistor is provided on each input for TTL compatibility.
Due to this feature, the execution times for each instruction are not specified. Thus, the busy flag is always 0 and the host never has to read the busy flag bit to determine if the modules are busy. A primary advantage of these modules over industry standard LCD modules is that they have a dual-port RAM that allows data and instructions to be sent to them continuously. Additional options include English-Katakana or English-European character font, with or without a connector, and internal or external reset function. The luminance level of the VFD can be varied by setting two bits in the function set instruction, which aredon t car bits for LCD modules.
#Futaba vfd serial generator
A character generator ROM with 240 5x8 characters is provided along with RAM for the user to program an additional 8 characters.

The modules can be configured for a Motorola M68-type parallel interface, an Intel I80-type parallel interface, or a synchronous serial interface. The modules are designed to be directly compatible with industry standard liquid crystal display (LCD) modules that utilize the Hitachi HD44780U LCD controller/driver. 1.0 GENERAL DESCRIPTION The Futaba Chip In Glass (CIG) LCD Emulator Vacuum Fluorescent Display (VFD) modules consist of a multiple character by multiple line 5x8 dot matrix display, DC-DC converter, and controller/driver circuitry.
