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 40 character lines.
LCD Smartie is open-source software for Microsoft Windows which allows a character LCD to be used as an auxiliary display device for a PC. Supported devices include displays based on the Hitachi HD44780 LCD controller, the Matrix Orbital Serial/USB LCD, and Palm OS devices (when used in conjunction with PalmOrb).
A 16×2-character dot-matrix display, where each character is made from a grid of 5×7 dots. A dot-matrix display is a low-cost electronic digital display device that displays information on machines such as clocks, watches, calculators, and many other devices requiring a simple alphanumeric (and/or graphic) display device of limited resolution.
Huang and Hitachi "Execution times" differ a little bit; about 2-3 ms. I don't think there was anything inaccurate in the lead because I got it from Huang too. However, this article needs a lot of work so the content may be incomplete. Calling the controller a display may be acceptable in a hobby shop but technically it is inaccurate and incorrect.
The Hitachi H8 is a large family of 8-bit, 16-bit and 32-bit microcontrollers made by Renesas Technology, originating in the early 1990s within Hitachi Semiconductor. The original design, the H8/300 , was an 8-bit processor that had a 16-bit registers and ALU that allowed some 16-bit operations.
Motorola 6845 CRT controller. The Motorola 6845, or MC6845, is a display controller that was widely used in 8-bit computers during the 1980s. [1] [2] Originally intended for designs based on the Motorola 6800 CPU and given a related part number, it was more widely used alongside various other processors, and was most commonly found in machines based on the Zilog Z80 and MOS 6502.
The last new model that could be considered part of this line was the Tandy 600, [21] [22] introduced in October 1985. Similar to the Tandy 200, it features a flip-up screen, but with 80 columns rather than 40. Built-in features include a 3.5" diskette drive, rechargeable batteries, and 32K of RAM expandable to 224K.
A TFT LCD is an active matrix LCD, in contrast to passive matrix LCDs or simple, direct-driven (i.e. with segments directly connected to electronics outside the LCD) LCDs with a few segments. TFT LCDs are used in television sets , computer monitors , mobile phones , video game systems, personal digital assistants , navigation systems ...
