The Hitachi HD44780 LCD controller is an alphanumeric dot matrix liquid crystal display (LCD) controller developed by Hitachi in the 1980s. The character set of the controller includes ASCII characters, Japanese Kana characters, and some symbols in two 28 character lines. Using an extension driver, the device can display up to 80 characters.

The Hitachi HD44780 LCD controller is limited to monochrome text displays and is often used in copiers, fax machines, laser printers, industrial test equipment, and networking equipment, such as routers and storage devices.

Compatible LCD screens are manufactured in several standard configurations. Common sizes are one row of eight characters (8×1), and 16×2, 20×2 and 20×4 formats. Larger custom sizes are made with 32, 40 and 80 characters and with 1, 2, 4 or 8 lines. The most commonly manufactured larger configuration is 40×4 characters, which requires two individually addressable HD44780 controllers with expansion chips as a single HD44780 chip can only address up to 80 characters.

Character LCDs use a 16 contact interface, commonly using pins or card edge connections on 0.1 inch (2.54 mm) centers. Those without backlights may have only 14 pins, omitting the two pins powering the light. This interface was designed to be easily hooked up to the Intel MCS-51 XRAM interface, using only two address pins, which allowed displaying text on LCD using simple MOVX commands, offering cost effective option for adding text display to devices.

R/W : Read/Write. 0 = Write to display module, 1 = Read from display module (in most applications reading from the HD44780 makes no sense. In that case this pin can be permanently connected to ground and no processor pins need to be allocated to control it.)

In 8-bit mode all transfers happen in one cycle of the enable pin with all 8 bits on the data bus and the RS and RW pins stable. In 4-bit mode, data are transferred as pairs of 4-bit "nibbles" on the upper data pins, D7-D4 with two enable pulses and the RS and RW pins stable. The four most significant bits (7–4) must be written first, followed by the four least significant bits (3–0). The high/low sequence must be completed each time or the controller will not properly receive further commands.

Selecting 4-bit or 8-bit mode requires careful selection of commands. There are two primary considerations. First, with D3-D0 unconnected, these lines will always appear low (0b0000) to the HD44780. Second, the LCD may initially be in one of three states:

The same command is sent three times, Function Set with 8 bit interface D7-D4 = 0b0011, the lower four bits are don"t care, using single Enable pulses. If the controller is in 4 bit mode the lower four bits are ignored so they can"t be sent until the interface is in a known size configuration.

In all three starting cases the bus interface is now in 8 bit mode, 1 line, 5×8 characters. If a different configuration 8 bit mode is desired an 8 bit bus Function Set command should be sent to set the full parameters. If 4 bit mode is desired 0b0010 should be sent on D7-D4 with a single enable pulse. Now the controller will be in 4 bit mode and a full 4 bit bus Function Set command sequence (two enables with command bits 7-4 and 3–0 on subsequent cycles) will complete the configuration of the Function Set register.

The original HD44780 character generator ROM contains 208 characters in a 5×8 dot matrix, and 32 characters in a 5×10 dot matrix. More recent compatible chips are available with higher resolution, matched to displays with more pixels.

Introduction:As we all know, though LCD and some other displays greatly enrich the man-machine interaction, they share a common weakness. When they are connected to a controller, multiple IOs will be occupied of the controller which has no so many outer ports. Also it restricts other functions of the controller.Therefore, LCD1602 with an I2C port is developed to solve the problem. It is also simple to handle. It has only two bidirectional data lines, a serial data line and a serial clock one.How to wire:GND-GND; VCC-VCC; SDA-A4; SCL-A5Features:Voltage: 5V DCLCD display type: CharactersModule dimension: 80mm x 35mm x 11mmData：1602 standard 16-pin interface, including:Pin 1: VSS is the ground power.2 feet: VDD then 5V positive power supply3 feet: V0 LCD contrast adjustment end, then the positive power supply when the contrast is the weakest, the highest contrast when grounded power, the contrast is too high will have a "ghosting", when used by a 10K potentiometer to adjust the contrast.4 feet: RS for the register selection, high-level data register selection, low-level instruction register selection.5 feet: R / W for the read and write signal lines, high-level read operation, low-level write operation.6th foot: E end is enable end, when E end jumps from high level to low level, the liquid crystal module carries out the order.7 ~ 14 feet: D0 ~ D7 for the 8-bit bidirectional data lines.15 feet: the positive power supply backlight16th foot: backlight power negative

The closest thing to a standard is, unfortunately, for LCD panels that have controllers but no drivers. IIRC, a typical interface will have signals for phase polarity, frame clock, line clock, data clock and 4 data bits. Every line of pixels one should clock in enough groups of four pixels to fill the width of the display (extra bits will be ignored), driving the data clock high and low for each group. The drive the line clock high and low to strobe the line. The first line of each frame should have the frame clock high, and the phase polarity signal should toggle every frame.

The line clock signals, and those derived from them, must be sent at a uniform rate. The precise timing of the data clock signals, however, doesn"t matter provided that all the clocks happen for a line happen within the proper window. If you don"t have DMA, it may be possible to keep a small display happy and still have time to do something else, but refreshing the display will be a pain. If you do have DMA, however, and can manage a small CPLD to handle a few aspects of the timing, implementing the display that way may be very rewarding. I"ve done a display panel like that and achieved display-update performance superior to anything I could have done with a conventional display controller. I even achieved 4-level gray-scale by running the display at 100 frames/second and, every three frames, driving the display twice using one buffer and once with another.

Having been in the business of designing embedded electronics for some time, we love all the old electronic stuff (ask us about our collection of 1980’s Atari vector arcade games in the break room!). So when we came across an “Advance Copy” of the Hitachi LCD Driver Data Book dated 1985 on eBay, we snapped it up.

To give you an idea or how long ago this was, this is a physical, paper, databook,not some ephemeral stream of coded electron states delivered from nebulous cloud. As far as we can tell, there is not ANY version information about the HD44780 chip in the databook. Our best guess is that there was only the one design, so there were not any versions to track.

The problem with physical paper books is that we can’t share that book with everyone. But we can share a high-resolution scan of the section of the data book that includes the HD44780 (delivered to you as an ephemeral stream of coded electron states) a PDF of the Advance Copy Datasheet for the HD44780!

So enjoy a little time travel back to 1985 when even a big company still used mono-spaced fonts printed on real paper to give you advance information on their brand new HD44780 LCD controller.
